2025 ANNUAL REPORT & FINANCIAL STATEMENTS

IOM3 supports professionals in materials, minerals, mining and associated technical disciplines to be champions of the transition to a low-carbon, resilient and resource efficient society. It seeks to be the best professional membership body it can be by providing modern, flexible services; quality technical content; and value for money.

Public benefit

Materials form an integral and important part of all our lives. The materials cycle covers the exploration and extraction of raw materials, processing them into industrial/engineered materials, application of these materials, recycling of waste and the ultimate disposal of waste in an environmentally responsible way. It’s more important than ever that the scientists, engineers and technologists involved in the materials cycle are qualified and experienced to make the best use of materials in terms of economics, efficiency and sustainability for the benefit of all. The objectives and activities of the Institute, together with government and other parties, have been designed to support and achieve these ideals. The Institute has referred to the Charity Commission’s guidance on public benefit when reviewing its aims, objectives, and future activities.

Vision

Advancing materials, minerals and mining through innovation and excellence for an inclusive and sustainable future.

Mission

Our activities promote and develop all aspects of the materials cycle, from exploration and extraction, characterisation, processing and application to product recycling, repurposing and reuse.

As the leading professional body representing the global materials, minerals and mining community, we champion excellence and innovation to drive responsible and efficient use of the planet’s resources. Acting as an inclusive and collaborative network, we advance science, engineering and technology across the entire materials cycle. In doing so, we promote sustainable solutions that create real value for our members, educators, researchers, producers, users and society at large.

As I look back on 2025, I can honestly say it was busy, uplifting and deeply rewarding. Becoming President of IOM3 is a pinnacle of my career and I remain truly honoured to hold this role. The warmth, enthusiasm and dedication I’ve seen across our community has made every visit and conversation a pleasure.

One of my aims as President has been to support and celebrate the full breadth of the Institute, from our staff teams in London and Grantham to our Affiliate Local Societies and Technical Communities. I firmly believe that these groups sit at the backbone of IOM3 and I’ve tried to meet as many of you as possible. I’ve had the pleasure of joining committee meetings, speaking at conferences and visiting society events around the country. Everywhere I’ve gone, the welcome has been warm and I’m grateful for the time and hospitality shown to me.

I’ve particularly enjoyed being able to join so many different activities throughout 2025. Meeting members from all parts of our community has been a privilege, especially our students and

early career professionals. Encouraging the next generation into the materials cycle is one of my key goals and hearing directly from people about their projects, ambitions and innovations has reminded me just how vibrant and capable our future workforce is. Their energy strengthens my belief that IOM3 must remain a place where people can learn, explore ideas and feel supported as they build their careers.

Last year I also had the privilege of speaking at events across the Institute. From opening Materials, Minerals & Mining for People, Places, Planet (M3P3) to welcoming delegates at the Advances in Mining Technology and Mineral Supply conference and addressing students at the University of Strathclyde, I’ve tried to bring enthusiasm and a sense of connection wherever I could. What has struck me at every event is the shared commitment to progress, responsible innovation and collaboration. We’re in an era of rapid change, from advances in mining technology to new materials and shifting supply chains, and our community continues to respond with expertise and purpose.

PRESIDENT’S OVERVIEW

3

I want us to keep strengthening our local societies, opening more opportunities for early careers, championing responsible and sustainable practice and ensuring that diversity, inclusion and high standards remain central to everything we do. I also remain committed to an open-door policy. If I can support, help or encourage you in any way, I am here to do so.

Thank you to everyone who has invited me to speak, welcomed me into their meetings or shared their work over the past year. Your dedication is what makes IOM3 such a strong and supportive community. I look forward to meeting even more of you in the coming year and continuing our work together.

In many respects, 2025 was a year of consolidation, with the new Membership Strategy being bedded in, our journal publishing partnership maturing and our improved approach to communicating with members flowing through the year. At the same time, we saw some real highlights, from the critical success of Materials, Minerals & Mining for People, Places, Planet (M3P3) in Birmingham in November, through our #WeAreIOM3 campaign, to the growing impact of our policy and influence work. As always, none of this would have been possible without the hard work and dedication of our active supporters and volunteers and the IOM3 team. Once again, we were also able to generate an operational surplus, which allows us to deliver more charitable activity and member benefits whilst keeping our membership fees reasonable.

Dr Colin Church CEnv FIMMM IOM3 CEO

Professional membership numbers remained broadly stable in 2025, though our overall numbers have fallen slightly, mainly due to delays in recruiting students. The Qualified for Minerals Reporting (QMR) scheme remains strong, and the numbers of people coming forward for professional registration

CEO’S REVIEW

mirror wider professional body trends. Having launched a tool to collect diversity information at the end of 2024, it’s good to see such a positive response, but if you have not yet completed it, please do so via your MyIOM3 webpage. This information helps us understand and support our members better.

Our member magazine, Materials World , continues to receive very positive feedback, and our increased output of online sector news saw greater interest this year. Our podcast series, IOM3 Investigates… has developed nicely, and webinars have been extremely popular. Our more traditional journals, conferences and events continue to deliver high quality content too, as do the events being run by our Affiliate Local and International Societies, who do so much to support local communities of professionals in materials, minerals and mining. If you haven’t already signed up to receive information about their activities, I strongly encourage you to do so, also via your MyIOM3 page.

‘Our work to champion materials, minerals and mining developed significantly last year. With more team members engaged in both our outreach work and our policy work, we were able to do more than ever.’

Some of 2025’s content highlights were:

Despite a difficult economic context for training, the IOM3 professional development offering remains strong. The Training Academy successfully ran 46 courses for over 300 learners, including three new courses in the popular Metallurgy in Practice suite. As metallurgy knowledge is consistently highlighted as a growing gap in the UK, this is not surprising!

There was great interest in our professional awards, with 152 nominations across 40 categories for the 2025 IOM3 Awards & Prizes and good interest for our Student & Apprentice Awards. Our third outing for the Sustainable Future Awards brought in another very impressive set of nominations.

Our work to champion materials, minerals and mining developed significantly last

year. With more team members engaged in both our outreach work and our policy work, we were able to do more than ever. Highlights for the former include a return of our teacher conferences and five Polymer Study Tours . On policy, our landmark report Materials Driven Missions: Delivering the Plan for Change highlighted the central role of materials, minerals and mining in achieving the UK government’s ambitions; a message we stress at every opportunity. We also continued to engage with government, including through membership of the Critical Minerals Expert Committee and the Circular Economy Taskforce.

In 2025, we also said goodbye to Irene Rudnicki, the Head of Membership, who is retiring after many years’ sterling service. We wish her well in this next stage!

My final word goes, as always and as is proper, in thanks: to the active supporters and volunteers who provide so much expertise and time to support IOM3, its charitable purpose and its members; and to the wonderful IOM3 team, who make working here a daily joy. We aim to continue delivering for professionals in materials, minerals and mining, and for society as a whole, for many years to come.

We worked with other Professional Engineering Institutions (PEIs) to participate in the third self-assessment against the new Progression Framework from the Science Council and the Royal Academy of Engineering.

In order to showcase and support the different communities within our membership, we have a regular calendar of activities to support various ‘awareness days’. In 2025, we saw increased participation from our Member Networks in social media campaigns and blogs. Coordinating activity through the calendar allowed us to take a more proactive approach and support a wider range of initiatives, such as Visibility in Engineering for UK Disability History Month and Global Accessibility Awareness Day.

We supported a dedicated Women in Materials, Minerals & Mining (WIM3) event for International Women’s Day and hosted a special in-person celebration in London, ‘Celebrating Women in Our Industries’, marking 12 years of WIM3.

We further improved the accessibility of our content through wider use of alt text on social media and website images.

The Institute has a Trustee Board of 15 people with 26% female representation, and our Advisory Council is 41% female. Across our full governance structure, IOM3 has 29% female representation. In 2026 we plan to expand our data collection to better understand our delegates and learners.

Materials World

A diverse range of contributors continued to write for the magazine and feature in the professional development section. The team actively sought to widen the pool of contributors and interviewees from varied backgrounds.

A steady stream of content addressed issues around equity, diversity and inclusion (EDI). Examples include articles on neurodivergence and engineering; decolonisation of materials science; developing a diverse workforce for the green transition; inclusive design; and supporting refugees coming to the UK to return to careers in STEM.

This also included profile pieces reflecting diverse backgrounds within materials, minerals and mining, as well as contributions from the IOM3 Pride, Ably Different (ADM3), Women in Materials, Minerals & Mining (WIM3) and Student & Early Career (SEC) networks.

Technical Communities

2025 saw the continued implementation of the revamped Technology Communities Board (TCB) and the introduction of several new Technical Community (TC) Chairs. Work began in late summer to review how our Strategic Advisors operate and where they provide coverage, to help strengthen collaboration across our Technical Communities and support the embedding of the nine technical themes.

years since the 2022 restructure, making it an appropriate point for the TCB and IOM3 staff to review progress.

We held an in-person TC Forum in September 2025, following the successful model of previous years. The event provided a valuable networking opportunity for TC Chairs, Strategic Advisors and IOM3 staff to share best practice and strengthen working relationships. The 2025 theme focused on the circular economy, with plenary talks from IOM3 CEO Dr Colin Church CEnv FIMMM on the work of the Circular Economy Taskforce, followed by Dr Flavie Lowres FIMMM, Chair of the IOM3 Construction Materials Group, who highlighted opportunities for material reuse.

The TCB set clear strategic objectives and metrics to monitor TC performance, and 2025 was the first full year of this framework being in place. Each TC submited an Annual Report at the end of the year through its leadership team, outlining activity against the agreed objectives and metrics. As in most years, the TC structure continued to evolve with new Chairs appointed and refreshed leadership teams to keep the communities active and engaged.

Technical Communities also played an important role in identifying speakers for M3P3 and aligning the technical themes.

We encourage all members to connect with their chosen TC via the MyIOM3 portal by selecting one primary TC and any number of secondary preferences. This helps us better understand members’ interests and tailor activities, content and events to meet their needs.

TC Chairs regularly reviewed the structure and operation of their leadership teams in line with TCB objectives and with a commitment to inclusivity. This work will continue into early 2026 as we reach four

TECHNICAL CONTENT

Events

We designed our events to be accessible and inclusive, offering features such as prayer rooms, quiet spaces and family-friendly options to reduce barriers to participation. Community-building activities, including photo competitions, WhatsApp groups and informal meet-ups, helped create a sense of belonging. Interactive elements like our mini golf networking game and relaxed social spaces gave attendees more opportunities to connect in ways that felt natural and engaging.

By the end of November 2025, our events had attracted a total of 6,477 delegates, of whom 61% were IOM3 members. Participants from 27 countries attended the in-person events.

The 2025 events programme generated strong support from sponsors and exhibitors, with organisations using their presence to raise their profile and network with industry professionals. Sponsors and exhibitors in 2025 included BAM Ritchies, AWE, SLR Consulting, Rolls Royce, Lucideon, Eco Belt and Cornish Metals.

Sustainability remains central to how we work. We moved away from plastic pull-up banners to fully recyclable eco banners and continued to reduce printed materials through the use of a conference app. These choices reflected our commitment to delivering events that support our members while having a positive impact on the wider community and the environment. This philosophy in action was recognised at the 2025 Memcom

Our approach to IOM3 events continued to focus on

sustainability and human connection, creating experiences that bring our community together in meaningful ways. We took a people-centred approach that prioritises individual needs and encouraged genuine interaction, to help participants make lasting connections and take away insights that extend beyond the event itself. We listened to attendee feedback and used it to shape our planning, ensuring each event built on what our community values most.

Materials, Minerals & Mining for People, Places, Planet (M3P3)

On 11 November we held M3P3 and the event buzzed with energy from start to finish. Delegates appreciated the chance to connect across sectors and share varied perspectives and ideas. One attendee described the conference as ‘a hugely impressive event with multi-faceted dialogues, thought-provoking plenaries and deep-dive breakouts’. Another told us it was ‘great to network with people in a similar field. Bringing multiple organisations into one room feels rare’.

Our Technical Communities were at the heart of the programme. Working across disciplines, they showed what makes IOM3 unique and how collaboration is shaping the future of our sectors. As one delegate said, ‘It was great to see all the communities together. The auditorium programme mixed up some of the common crossover topics which worked well.’

M3P3 came alive because of our community. Every conversation, question and shared experience helped shape the event. Thank you to everyone who joined us, contributed to sessions, or simply made time to connect with others.

Member magazine

Our in-house team of journalists continued to deliver a broad range of high-quality content, maintaining strong editorial and reporting standards. Their work supports multidisciplinary coverage across materials, minerals and mining and our nine technical themes, helping members stay informed and supporting ongoing professional development. We aim to make our content as accessible as possible so that readers can see connections between their own field and developments in other sectors.

We used a wide mix of content types, including news, features, professional development pieces, event reports, thought leadership and profiles covering technical, industrial, policy and EDI topics. This variety helped us engage readers, supported strong social media traction and encouraged contributors from across our community to share their work with us.

This broad scope helps nurture relationships with academia, industry, members, non-members and partner organisations. In 2025 we continued to see strong engagement and contributions from our Technical Communities, alongside input from prominent organisations such as the Henry Royce Institute, the Faraday Institution, the Critical Minerals Intelligence Centre, UK Research and Innovation and the Foundation Industries Sustainability Consortium.

Through our coverage, we continued to highlight the contribution our sectors make to a low-carbon, resource efficient society. Materials World featured key IOM3 policy areas and outputs, including critical minerals, the energy transition, the need for a national materials strategy, the transformation of the Foundation Industries and the circular economy.

21

Podcasts

The IOM3 Investigates… podcast series continued to grow in both reach and variety, with episodes covering topics ranging from communicating STEM to the pathways open to early career professionals. We introduced new strands, including re-edited archive episodes, contributions from the IOM3 Student & Early Career Group and forthcoming digitised versions of historical recordings. The 2026 line-up is already in development and will explore a similarly wide range of subjects, reflecting all nine themes.

Online Industry News

Engagement with our online industry news remained strong. In 2025 we increased the amount of content published each day to reflect the breadth of our members’ interests and to keep them up to date with policy, science and industry developments.

22

Journals

Our journals continued to perform well in 2025, with strong results across key metrics this year.

Several journals recorded significant rises in impact factors, reflecting the growing influence of our research community. Highlights include Materials Science and Technology (MST) and Ironmaking & Steelmaking (IRS), both rising from 1.7 to 2.2, and Mining Technology, which increased from 1.8 to 2.2. The standout achievement came from Applied Earth Science, which saw a 56% increase in its impact factor, rising from 0.9 in 2023 to 1.4 in 2024 (results released in 2025).

International Materials Reviews (IMR) maintained its Q1 ranking, placing 29th out of 460 journals in Materials Science, Multidisciplinary . In addition, four titles achieved Q2 rankings this year, doubling the number from last year. These were Interdisciplinary Science Reviews (ISR), Science and Technology of Welding and Joining (STWJ), MST and IRS.

We’re updating the aims and scopes of several journals to better reflect emerging research areas. Work has started on Materials Science and Technology (MST), with exciting changes planned for 2026 and beyond under the leadership of Dr Radhakanta Rana FIMMM, a member of the IOM3 Iron & Steel Technical Community Leadership team and recipient of the 2025 IOM3 Gold Medal.

Members have full and free access to the complete IOM3 journal portfolio, along with a wide range of additional titles, all available through via MyIOM3 publications.

23

Library

In 2025 the IOM3 Library continued to support members and researchers across the materials, minerals and mining community through access to resources, information services and new outreach and storytelling activities.

Our online catalogue, ICON, holds more than 170,000 records, including books, journals, maps, reports, theses and digitised media. In 2025 our scientific and industrial collections were strengthened by generous donations from several long-standing members. The most significant addition came from the personal library of W A (Frank) Tandy, a long-standing member with a distinguished history in rubber and materials science, who donated his extensive collection on the history of rubber, spanning works from the Spanish conquest of the Americas to the present day.

We expanded our digitisation work, with a particular focus on the cassette archive of the Plastics Historical Society, making rare interviews and recordings more accessible. Work is also underway on a series of online exhibitions that will showcase highlights

from our archive collections. These exhibitions will bring historical materials to life, link them to contemporary themes in science, industry and society, and make them more accessible to members.

At our Grantham site, we curated a new display of thirty historical objects, each supported by research into its provenance and significance. The display reflected the depth and diversity of our collections and sparked new conversations about the history of materials and mining. Looking ahead to 2026, we will exhibit the Institute’s collection of Viva Talbot prints at Grantham, offering a fresh opportunity to explore the intersection of art, industry and social history.

Like all archives, our collections face risks of deterioration. To support long-term preservation, we introduced new processes to monitor environmental conditions in the library. Daily checks on humidity and temperature, along with systematic stack rotation, will help protect the collections and ensure they remain accessible for future members.

Training & Apprenticeships

2025 was another busy year for the Training Academy. Despite a challenging market, we successfully ran 46 courses for more than 300 learners. We launched several new courses, including three additions to our popular Metallurgy in Practice suite: Introduction to Ferrous Metallurgy, Introduction to Stainless Steels and Introduction to Material Certificates. We also introduced a new Metals Process suite with courses on Powder Metallurgy, Heat Treatment and Metals Processing Fundamentals to complement our existing Additive Manufacturing course.

We expanded our training offer for mining and mineral processing professionals with the launch of our Introduction to Mining course and we look forward to building on this in 2026 with a course on Responsible Mining Principles. Ahead of the Geometallurgy conference in June, the teams collaborated to deliver two half-day workshops linked to the conference theme.

In the second half of 2025 we have trialled an increase in the member discount on Training Academy courses from 10% to 20%. For our virtual and classroom courses we also tested an early bird rate, offering an additional 10% discount for bookings made more than eight weeks in advance. These changes enabled more members to access our courses and look forward to continuing them into 2026.

2025 was also a busy year for End Point Assessment activity, with 22 candidates completing their Level 3 Composites Technician apprenticeship. The autumn term was equally active, with apprentices completing their Level 6 Materials Science Technologist apprenticeship and 12 candidates completing their EPA.

INFLUENCE

School support

2025 got off to a strong start as we returned to the Association of Science Education annual conference to relaunch the School Affiliate Service (SAS) for 5-19 educators. More than 800 teachers are now subscribed to access support that will help them teach materials, minerals and mining across the school curriculum.

We ran our first teachers’ conference in many years on 12 November as part of M3P3 called ‘Materials Minerals & Mining for the Energy Transition’. This was delivered with support from passionate volunteers from the Energy Transition and Energy Materials groups. Teachers took away a set of seven posters with accompanying notes, enabling them to run the same interactive activity back in their classrooms.

Materials Matter celebrated its tenth anniversary in 2025, and returned to Luxfer MEL Technologies in March and Rolls Royce plc Bristol in July. We also ran a special Materials Minerals & Mining Matter event ahead of M3P3 and Discover Materials and Minerals Matter/Future is Mine provided workshops to inspire the young people who attended.

The Magic of Materials course also celebrated a milestone year. Delivered with St Paul’s School and supported by Discover Materials Ambassadors, the tenth course welcomed a bumper group of 14- to 15-year-olds and, for the first time, included a parallel workshop for teachers. In June and November, we ran five Polymer Study Tours (PST) for around 60 secondary school design and technology teachers at WHS Plastics Larkhall, Victrex, Bericap, Biffa Polymers and for the first time at Amcor (formerly Berry Global).

The Starpack Schools competition saw 86 schools register to take part. The brief, closely linked to the secondary school design and technology curriculum, required young people to design packaging to safely transport four celebration sweet treats through the post. We received a total of 87 entries across three categories (years 7 & 8, years 9 & 10, and year 12). Judges commented on the high standard of submissions and we celebrated the winners at a special event on 5 December.

35

2025 Polymer Study Tour delegate feedback:

‘Professional development of this quality is increasingly hard to come by.‘

‘It was a genuinely inspiring experience that gave me time to reflect, learn, and reconnect with why I love teaching Design and Technology.‘

Education & Outreach Trust

The IOM3 Education & Outreach Trust continued to provide vital funding to initiatives which develop interest, recognise excellence and support professional development in materials, minerals and mining.

Developing interest

Resource development and STEM Intervention Access grants awarded to support the teaching of chemistry, contribute to the cost of purchasing equipment for a school design & technology workshop. They enabled a school to run a materials-focused competition and support an undergraduate outreach project.

Recognising excellence

In addition to the IOM3 Student & Apprentice Awards, the Trust provided funding to enable best student poster and presentation prizes to be awarded at the Ferroelectrics UK & Ireland conference.

Supporting professional development

‘I am really excited to put the knowledge I gained on the course into my teaching to benefit my students.‘

The Trust awarded two large research grants, 20 smaller travel grants to allow early career researchers to present their work at technical conferences and funded free tickets for student and early career members to attend M3P3.

36

Policy

2025 was an impactful year for IOM3 policy activity. Through direct engagement with government officials, proactive policy reports, representation on government taskforces and new resources to support members in navigating the policy landscape, our influence continued to grow.

Championing the role of materials, minerals and mining

In 2025, we launched our landmark report Materials Driven Missions: Delivering the Plan for Change , which highlights the central role of materials, minerals and mining in achieving the UK government’s ambitions. The report calls for a strategic and sustainable approach to managing material resources and was shaped by extensive member expertise, including input from 11 Technical Communities and five Strategic Advisors.

Ahead of the Spending Review, we published our key asks of government, setting out the fundamental importance of materials, minerals and mining to the UK’s economy, health, energy transition and national security. Our submission called on government to address the following priorities:

  1. Establish and implement a UK Materials Strategy

  2. Advance the transition to a more circular economy

  3. Bolster the UK’s approach to critical materials

  4. Support energy intensive industries to decarbonise

  5. Deliver a skills and workforce development plan across materials, minerals and mining

37

Following the cabinet reshuffle, we sent congratulatory letters to the newly appointed Secretaries of State underlining the key contribution materials, minerals and mining make across their respective department’s priorities.

Harnessing the knowledge of our members, we responded to a wide range of consultations and parliamentary inquiries in 2025 – including the steel strategy, Building the North Sea’s Energy Future, the Modern Industrial Strategy and the Defence Industrial Strategy statement of intent.

Collaborating and amplifying member voices

We partnered with the Institution of Chemical Engineers and the Royal Society of Chemistry, supported by the Department for Business and Trade, to gather insights from across our communities and publish a report on the skills required to support a circular economy. We met with the Department for Business & Trade, the Department for Energy Security & Net Zero, and the Department for Environment, Food & Rural Affairs to share the report’s key findings and feed them directly into government policymaking.

Building on our earlier report, The talent gap: critical skills for critical materials , we collaborated with the Department for Business and Trade, the Critical Minerals Association UK, Innovate UK and Imperial College London to hold a workshop that brought together stakeholders to explore the challenges and opportunities in developing skills for domestic midstream and recycling capabilities.

Empowering members to engage with policy

To help members better understand and engage with the policy process, we launched a series of policy explainers. These guides break down how government policymaking works, covering areas such as select committees, consultations, and taskforces, illustrate how IOM3 engages and how members can get involved and contribute. You can find them via our policy pages on the IOM3 website.

38

UNDERPINNING INFRASTRUCTURE

People

During the year, we welcomed three new team members: Zanna Buckland as Staff Writer, Joe Hinds as Facilities and AV Assistant and Loretta Williams as Technical Community Support. In December 2025, Irene Rudnicki, our Head of Membership retired, and the membership team was reorganised to better support our colleagues and members.

We created a quiet room in London and began redesigning the Grantham space to provide private areas for reflection, relaxation or prayer. The team also supported several charities, including Macmillan and Save the Children.

The team visited the AMRICC Centre to see materials testing in action and enjoyed a competitive day at Clays for our annual IOM3 Team Day.

In order to celebrate team members who live our values of Professional, Inclusive, Supportive and Agile (PISA), we present an award in each category. Congratulations to last year’s winners whose dedication and teamwork have made a real difference: Professional - Tia Byer, Inclusive - James Lee, Supportive - Sue Harris and Julie Fitt and Agile - Dilyana Todorova

Right: IOM3 is committed to creating a positive, inclusive and supportive working environment. Our four values define who we are.

39

Below:

We created a new ‘Why work with us’ landing page to highlight our values.

Digital

During 2025, we continued improving our digital platforms while planning for future developments. This included various improvements to the MyIOM3 member experience, reviewing images to improve alt text and aid accessibility, and a check of member email address validity. We also undertook our annual website content and structure review, updating information and links.

Looking ahead to 2026 and beyond, IOM3 is entering a new phase of our digital transformation. A working group from the Executive Board is scoping a new CMS (website), DMS (digital marketing system) and EMS (events management system) to provide our team and members with improved functionality and engagement.

40

Building

Since 2020, we’ve made significant progress in reducing its carbon footprint. In 2025, we reduced our scope 1 and 2 emissions to 11.39 tCO2e, over a 93% drop from the 2019 baseline of 170 tCO2e. We continue to purchase 100% renewable energy where possible and installed solar panels at 297 Euston Road, London.

In 2025, we expanded our scope 3 emissions reporting. Working with suppliers improved data quality and transparency. Total 2025 emissions were 391.5 tCO2e including investments and 74.87 tCO2e excluding investments this is a further reduction of over 10tCO e in non-investment emissions from 2024. 2

In 2025, our London Headquarters was awarded a Gold Eco Smart Award for sustainable venues, building on our Silver award from the previous year.

We continued promoting venue hire through seasonal campaigns. The summer offer gave 20% off bookings in July and August, with drinks and refreshments. The festive campaign offered the same discount for December, plus complimentary prosecco or soft drinks and mince pies. Both campaigns encouraged early booking and added value to client events.

In 2024 trustees engaged an independent investment advisor to review IOM3 investment policy and strategy to de-risk IOM3 investments portfolio and align income generation and capital growth with IOM3 strategy and future business needs. Following review, trustees agreed to diversify both restricted and unrestricted investment portfolios and move investments to a number of different funds. Transition from BlackRock portfolio commenced in November 2024 and was completed in March 2025. IOM3 investments are now split between Rathbones Investment Management discretionary fund and Waverton Investment Funds plc absolute return, real asset, sterling bond and strategic equity funds.

Formal valuation of IOM3 freehold property was last carried out in 2023. Having reviewed the open market value of freehold properties in the Fitzrovia area and consulted the property price index, trustees agreed that the value of IOM3 freehold property should be increased as at 31 December 2025. An uplift of 2% was applied to the freehold property value resulting in unrealised gain on valuation of £147k and a final year end value of £7,509k.

Restricted funds

IOM3 Education & Outreach Trust was granted charity registration by Charity Commission of England and Wales at the end of 2022 under the number 1201414. Since then trustees have worked with Charity Commission to broaden the objects of various IOM3 restricted funds and align them with objects of IOM3 Education & Outreach Trust. The trustees have subsequently applied to Charity Commission and were granted permission to transfer a number of restricted funds to IOM3 Education & Outreach Trust, with IOM3 donating a total of £930k to IOM3 Education & Outreach Trust during the year. Details of the funds donated are listed in note 19 on p.88. 2025 marked the first year of operations for IOM3 Education & Outreach Trust and its results are shown in note 13 on p.84.

In 2025 IOM3 general fund generated an operating deficit of £197k (2024 – surplus of £113k). After taking into account realised and unrealised gains on disposal and market value of IOM3 investment portfolio and actuarial gains on the defined benefit pension scheme and gain on revaluation of freehold property and movement in restricted and designated funds, IOM3 ended 2025 with an overall surplus of £841k (2024 - £1,679k).

43

Reserves review

The Trustees’ policy on reserves is to:

Principal risks and uncertainties

Trustees have identified the following major risks facing the Institute:

The risk register is being reviewed and updated on a regular basis and the trustees, employees and professional advisors are taking steps to mitigate these risks and minimise their impact on the Institute’s future performance.

The trustees set a budget for net operating surplus of £23k for 2026 (before depreciation and defined benefit pensions scheme costs) to support ongoing initiatives for the development of membership, training and conference programmes.

Objectives & activities

The charitable objects of IOM3, as set out in the Royal Charter, are:

To advance and develop all aspects of science, engineering and technology as applied to the discovery, exploration, development, characterisation, exploitation, processing, application and re-cycling of materials, minerals and fuels, to further and co-ordinate education, training and practice in these disciplines and to facilitate the acquisition, preservation and dissemination of knowledge pertaining to these disciplines, provided that in pursuing these objects, in so far as they may be similar to those of existing organisations, the Institute shall use its best endeavours to co-operate with them and to ensure that its activities are complimentary to those of such organisations.

Our Corporate Strategy sets two objectives for IOM3:

  1. To support professionals in materials, minerals and mining to be champions of the transition to a low-carbon, resilient and resource efficient society.

  2. To be the best professional membership body it can be.

Through our activities we aim to:

Raise the profile of our sectors as technologies vital to the health and wealth of the nation; engage in public, policy and media debate to increase the visibility of materials, minerals and mining.

IOM3 has always worked closely with Government in relation to the delivery of new technology to industry. We are also increasingly deploying the expertise of our members to influence the public, media and policy debates that have materials, minerals and mining aspects, including through participation in Government advisory groups and contributing to public and parliamentary consultations. Our communications efforts also explain the vital importance of materials, minerals and mining to the future of our society.

Stimulating innovation in the extraction, use and application of materials, IOM3 organises both UK and worldwide competitions to develop a broad understanding of the importance of materials, minerals and mining, and such events engage with schools, students and businesses from the UK and beyond. Separately, IOM3 provides an extensive range of awards both to members and non-members who have provided outstanding contributions to our communities and professions.

51

Support people within the materials, minerals and mining sectors to address the societal challenges we face today such as climate change, equity, diversity and inclusion, etc.

The Sustainable Future theme brings together many IOM3 activities that seek to ensure our members and wider society understand how materials, minerals and mining need to contribute to the transition to a low-carbon, resilient and resource efficient society. Both individually, and as part of the wider networks of engineering, environmental and scientific professional institutions, IOM3 encourages and promotes the participation of under-represented and minority groups in the engineering, environment and science professions. To help support and encourage individuals in STEM careers who share particular characteristics or non-technical interests, IOM3 has created five Member Networks (ADM3, EMM3, IOM3Pride, SEC and WIM3).

Support and encourage education in materials, minerals and mining to attract young people to the profession.

IOM3 accredits a number of university, college and industry courses in the UK and overseas, and provides a special low-cost membership package for undergraduates which is often sponsored by local societies or by their university. The thriving Student & Early Career Group organises regular events for students and early career members. IOM3 has an active education programme that enriches the teaching of materials, minerals and mining in the curriculum and promotes careers within our sphere of influence. We provide help, advice and teaching materials free of charge to teachers that have signed up to our School Affiliate service and to date over 1,200 schools have registered. Our schools presentations have so far been delivered to more than 100,000 pupils throughout the UK. The team also organises study days for teachers and events to allow older pupils to interact with young people already working in the sector. Together with the IOM3 Education & Outreach Trust we provide financial support for schools, students and early career researchers.

52

Provide a central resource of expertise and information through content; disseminate information through conferences, events, publications, online resources and social media; increase the visibility of new technology to industry; provide networking opportunities through technical, local and other activities to increase interaction between industry, academia and government.

IOM3 publishes technical books, learned journals and member magazines and organises conferences on materials, minerals and mining related subjects. The publishing of learned journals is outsourced to Sage Publishing. Access to this material is available to both members and non-members. In-house teams publish the member magazines and organise the majority of conferences. IOM3 maintains an extensive resource of technical and historical publications that form the core of our information and library services, a source of expertise accessible to all. The IOM3 Technical Enquiries service provides consultancy and advice services to anyone who needs access to expertise in materials, both individuals and organisations. Of the 1,500 enquiries routinely handled each year, 50% originate from the UK public. The Business Partner Programme enables organisations to visibly associate themselves with IOM3 and access its resources and work programmes. Confirmed subscribers to date include Lucideon, National Composites Centre and Lloyds Register.

IOM3 organises dozens of events every year covering a wide range of topics of relevance to professionals in materials, minerals and mining. In addition, we partner with other organisations to support similar activities, including the UK-wide network of local societies affiliated to IOM3, our international affiliated societies, other UK and international professional bodies and learned societies and other like-minded organisations.

Provide our members with benefits, services and opportunities to support their careers.

IOM3 technical communities, boards and committees are all composed of active supporters and volunteers (ASVs) drawn from the IOM3 membership, who freely give their time and expertise to deliver the Institute’s charitable purposes and professional activities, develop our communities and provide peer review processes where needed. IOM3 depends on the engagement of our members in the broad range of our activities and could not deliver our objectives effectively without their significant contribution. IOM3 members play a prime role in promoting our objectives and providing public benefit. Accordingly, a wide range of member services and benefits have been developed in pursuance of our objectives and to attract new members. Benefits of membership include professional recognition, networking opportunities to share knowledge and experience, free technical enquiry services, a choice of members’ magazine, a members’ business centre and use of facilities, discounted conference fees, training courses and publications, and additional online services. In addition, the regulation of the profession provides benefits to both members – who are recognised as competent and professional – and to wider society.

IOM3 provides support to our worldwide membership through our UK offices, our technical communities and societies, and our network of affiliated local societies and national groups. Career progression is recognised through various grades of membership and IOM3 is licensed to deal with applications for Chartered Engineer, Incorporated Engineer, Engineering Technician, Chartered Environmentalist, Registered Environmental Practitioner, Chartered Scientist, Registered Scientist and Registered Science Technician status.

Independent auditor’s report to the Trustees of the Institute of Materials, Minerals & Mining

Opinion

We have audited the financial statements of The Institute of Materials, Minerals and Mining for the year ended 31 December 2024, which comprise the Consolidated Statement of Financial Activities, the Consolidated and Parent Balance Sheets, the Consolidated Statement of Cash Flows and notes to the financial statements, including a summary of significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102, the Financial Reporting Standard applicable in the UK and Republic of Ireland (United Kingdom Generally Accepted Accounting Practice).

In our opinion the financial statements:

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the financial statements section of our report. We are independent of the group in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s Ethical Standard, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Conclusions relating to going concern

In auditing the financial statements, we have concluded that the trustees’ use of the going concern basis of accounting in the preparation of the financial statements is appropriate.

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the group’s ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.

Our responsibilities and the responsibilities of the trustees with respect to going concern are described in the relevant sections of this report.

59

Other information

The trustees are responsible for the other information. The other information comprises the information included in the Trustees’ Annual Report and the Letter from the Chair and Letter from the Chief Executive. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon.

In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements, or our knowledge obtained in the audit or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether there is a material misstatement in the financial statements or a material misstatement of the other information. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard.

Opinions on other matters prescribed by the Companies Act 2006

In our opinion, based on the work undertaken in the course of the audit:

Matters on which we are required to report by exception

In the light of the knowledge and understanding of the group and the parent charitable company and its environment obtained in the course of the audit, we have not identified material misstatements in the Trustees’ Annual Report (which incorporates the strategic report and the directors’ report).

We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 and the Charity Accounts (Scotland) Regulations (as amended) require us to report to you if, in our opinion:

60

Responsibilities of trustees for the financial statements

As explained more fully in the trustees’ responsibilities statement set out on p53, the trustees (who are also the directors of the charitable company for the purposes of company law) are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the trustees determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the trustees are responsible for assessing the group’s and the parent charitable company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the trustees either intend to liquidate the group or the parent charitable company or to cease operations, or have no realistic alternative but to do so.

Auditor’s responsibilities for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below.

Based on our understanding of the group and the environment in which it operates, we identified that the principal risks of noncompliance with laws and regulations related to company and charity law in England and Wales, company and charity law in Scotland and compliance with overseas laws and regulations in the jurisdictions the Group operates in. We considered the extent to which non-compliance might have a material effect on the financial statements. We also considered those laws and regulations that have a direct impact on the preparation of the financial statements such as the Companies Act 2006 and the Charities Act 2011, Charity Accounts (Scotland) Regulations (as

61

amended), Charities and Trustee Investment (Scotland) Act 2005 and the impact of payroll taxes and sales taxes.

We evaluated management’s incentives and opportunities for fraudulent manipulation of the financial statements (including the risk of override of controls), and determined that the principal risks were related to posting inappropriate journal entries to revenue, the cut-off of revenue at the year end and management bias in areas of accounting estimate. Audit procedures performed by the engagement team included:

Use of our report

This report is made solely to the charitable company’s members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006, section 44(1)(c) of the Charities and Trustee Investment (Scotland) Act 2005 and regulation 10 of the Charities Accounts (Scotland) Regulations 2006. Our audit work has been undertaken so that we might state to the charitable company’s members those matters we are required to state to them in an Auditor’s report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the charitable company and the charitable company’s members as a body, for our audit work, for this report, or for the opinions we have formed.

A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council’s website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report.

Accounting policies

Basis of financial statements

The Institute of Materials, Minerals and Mining (“the Charity”) is an unincorporated charity domiciled in England. The address of the Charity’s registered office and principal place of business is 297 Euston Road, London NW1 3AD.

The Charity’s principal activities and the nature of the Charity’s operations are described in the Trustees’ Report on pages 50-53.

The financial statements have been prepared in accordance with Accounting and Reporting by Charities: Statement of Recommended Practice applicable to charities preparing their accounts in accordance with the Financial Reporting Standard applicable in the UK and Republic of Ireland (FRS 102) (effective 1 January 2019) – (Charities SORP (FRS 102)), the Financial Reporting Standard applicable in the UK and Republic of Ireland (FRS 102) and the Charities Act 2011.

The Institute of Materials, Minerals and Mining meets the definition of a public benefit entity under FRS 102. Assets and liabilities are initially recognised at historic cost or transaction value unless otherwise stated in the relevant accounting policy notes.

The financial statements are prepared in sterling, which is the functional currency of the Charity. Monetary amounts in these financial statements are rounded to the nearest £1,000.

Preparation of the accounts on a going concern basis

The Trustees confirm that at the time of approving these financial statements, there is a reasonable expectation that the Institute has adequate resources to continue for the foreseeable future. In arriving at this conclusion, the Trustees have taken into account the current and anticipated financial performance in the current economic conditions and the charity’s reserves position. The Trustees have considered forecasts to June 2027. The Trustees are satisfied that the charity has adequate reserves and strategies in place and have concluded that it remains appropriate to prepare the financial statements on the going concern basis.

Group financial statements

The financial statements consolidate the results of the wholly owned subsidiary companies and companies over which the Institute exercises dominant influence on a line-by-line basis. The members’ benevolent funds are not consolidated because they are under independent control.

Details of the Institute’s total incoming resources and net movement in funds are shown in the notes.

Income

Income is recognised when the charity has entitlements to the funds, any performance conditions attached to the items of income have been met, it is probable that the income will be received and the amount can be measured reliably.

Subscription income represents the amount received in respect of current and past years. Amounts received in advance are carried forward to the following year and subscriptions in arrears have not been anticipated.

Income from conferences represents the amount receivable in respect of the current year. Amounts received in respect of conferences to be run in future years are carried forward to the following year.

Incoming resources from grants, where related to performance and specific deliverables, are accounted for as the charity earns the right to consideration by its performance.

Other income is recognised where there is entitlement, probability of receipt and the amount can be measured with sufficient reliability.

67

Expenditure

Expenditure is recognised once there is a legal or constructive obligation to make a payment to a third party, it is probable that settlement will be required and the amount of the obligation can be measured reliably.

All expenditure is accounted for on an accruals basis and has been classified under headings that aggregate all costs related to the category. Where costs cannot be clearly attributed to particular headings they have been allocated to activities on a basis consistent with the use of the resources. Overheads have been allocated on the basis of head count.

Grants and prizes are awarded annually, mainly to affiliated societies and individuals.

Allocation of support costs

Support costs comprise employment, establishment and administration costs in support of the charitable activities of the Institute. Allocations of these costs are made to the various activities of the Institute using standard rates based on staff time involved on each activity and facility usage. The basis on which support costs are allocated is set out in note 7.

Tangible fixed assets depreciation and amortisation

Individual fixed assets are capitalised where the purchase price exceeds £1,500.

Depreciation is calculated by reference to the cost of fixed assets using the straight line method at rates considered appropriate having regard to their expected useful lives. The bases used are:

Freehold Property (excluding land)
Leasehold property		 2% p.a.
over the term of the lease
Furniture 15%-20% p.a.
Equipment 20%-33% p.a.

Impairment reviews are carried out where there is an indication that the recoverable amount of a fixed asset is below its net book value. Any such impairments are charged through the Statement of Financial Activities in the year in which the impairment occurs.

Freehold property is accounted for using the revaluation method with the building element depreciated at a rate of 2% per annum and revalued to its market value at the end of the financial year. The net value of gains on revaluation are held in the revaluation reserve.

Donated services and materials

Where services are provided to the Institute as a donation that would normally be purchased from suppliers, this contribution is included in the financial statements at an estimate based on the value of the contribution to the Institute.

Heritage Assets

A description of heritage assets held by the Charity is given in note 11. These assets were formally valued in April 2025 and details are given in note 11.

The Trustees have considered the value of the assets at 31 December 2025 and are satisfied that the previous valuation remains materially accurate.

The heritage assets have been recognised in the Institute’s balance sheet at valuation.

The Institute’s freehold property is recognised in the financial statements at its market value. Details of the valuation at 31 December 2025 are given in note 10.

Intangible fixed assets

Intangible fixed assets, including patents and software, are amortised at rates calculated to write off the assets on a straight line basis over their estimated useful economic lives. Where it is not possible to make a reliable estimate of the useful life of an intangible asset, the life shall not exceed five years. Impairment of intangible assets is reviewed where circumstances indicate that the carrying value of an asset may not be fully recoverable. Intangible fixed assets are amortised over the following periods:

Website and software costs 4-5 years

68

Investments and investment income

Listed investments are shown at market value at the balance sheet date. Realised and unrealised gains or losses are taken to the fund to which they relate via the Statement of Financial Activities in the year in which they arise. Unlisted investments are held at cost. Income is included together with the tax related credit in the financial statements of the year in which it is receivable. Investment income and any gain or loss on the asset development and service development designated funds is taken to general funds.

Stocks and work in progress

Sundry stocks are valued at cost. Work in progress is valued at cost and includes staff and other overheads.

Debtors

Trade and other debtors are recognised at the settlement amount due after any trade discount offered. Prepayments are valued at the amount prepaid net of any trade discounts due translated at the rate of exchange ruling at the balance sheet date. Transactions in foreign currencies are recorded at an internal rate of exchange ruling at the date of the transaction. All differences are taken to the Statement of Financial Activities.

Cash at bank and in hand

Cash at bank and in hand includes cash and short term highly liquid investments with a short maturity of three months or less from the date of acquisition or opening of the deposit or similar account.

Creditors and provisions

Creditors and provisions are recognised where the charity has a present obligation resulting from a past event that will probably result in the transfer of funds to a third party and the amount due to settle the obligation can be measured or estimated reliably. Creditors and provisions are normally recognised at their settlement amount after allowing for any trade discounts due.

Financial instruments

The Institute only has financial assets and financial liabilities of a kind that qualify as basic financial instruments. Basic financial instruments are measured at their settlement value.

Foreign currencies

Assets and liabilities denominated in foreign currencies are translated at the rate of exchange ruling at the balance sheet date. Transactions in foreign currencies are recorded at an internal rate of exchange ruling at the date of the transaction. All differences are taken to the Statement of Financial Activities.

Operating leases

The rentals under operating leases are charged to the Statement of Financial Activities on a straight line basis over the lease term.

Irrecoverable VAT

Irrecoverable VAT incurred in respect of the year is included in the Statement of Financial Activities except for any amounts relating to capital expenditure which are included in the cost of fixed asset additions.

Pension costs

The Institute participates in both a defined benefit scheme and defined contribution schemes.

Under the defined benefit scheme, the Institute makes contributions to The Institute of Materials Pension and Life Assurance Scheme. Pension costs are assessed in accordance with actuarial advice and based on the most recent actuarial valuation of the scheme. The scheme was closed to new entrants during 2002 and was closed to accrual on 31 December 2021.

The assets of the scheme are held independently from the Institute in separate trustee administered funds. Full actuarial valuations, by a professionally qualified actuary, are obtained at least every three years, and updated to reflect current conditions at the balance sheet date. Fair value is based on the market price information and in the case of quoted securities is the published bid price.

69

The pension scheme assets are measured at fair value. The pension scheme liabilities are measured using the projected unit method and discounted at the current rate of return on a high quality corporate bond that has been rated at AA or equivalent basis of equivalent term and currency. A pension scheme asset is recognised in the balance sheet only to the extent that the surplus may be recovered by reduced future contributions or to the extent that Trustees have agreed a refund from the scheme at the balance sheet date. A pension liability is recognised to the extent that the group has a legal obligation to settle the liability.

The actuarial gain or loss arising in the year is included under ‘other recognised gains or losses’. Contributions are charged to expenditure so as to spread the regular cost of pensions over the expected working lives of the employees in the scheme. Any difference between the cumulative amounts charged and contributions paid is included as an asset or liability on the balance sheet.

The interest element of the defined benefit cost represents the change in present value of scheme obligations relating to the passage of time and is determined by applying a discount rate to the opening present value of the benefit obligation, valuing into account material changes in the obligation during the year. The expected return on plan assets is based on an assessment made at the beginning of the year of long-term market returns on scheme assets adjusted for the effect on the fair value of plan assets of the contributions received and benefits paid during the year. The difference between the expected return on plan assets and the interest costs is recognised in the consolidated SOFA (Statement of Financial Activities) as pension finance income or within resources expenses as appropriate.

Under the defined contribution schemes, the Institute contributes to group personal pension plans providing benefits for some employees. Pension costs are based on current salaries and charged to the statement of financial activities in the year in which they are due.

Critical accounting estimates and assumptions

The Institute makes estimates and assumptions concerning the future. The resulting estimates and assumptions will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are those used by the scheme actuary in calculating the Institute’s defined benefit scheme liability (see note 22 for details).

Revaluation of freehold property: the revaluation is based on the building element of freehold properties depreciated at a rate of 2% per annum and revalued to its market value at the end of the financial year (see note 10 for details).

Institute funds and reserves policy

Funds held by the Institute are:

Further explanation of the nature and purpose of each fund is included in the notes to the financial statements.

10. Tangible fixed assets (continued)

The Institute’s freehold land and buildings are accounted for using the valuation method. The London property was formally valued at its market value of £7.33m by Michael Riordan MRICS on 18 December 2023. Trustees have reviewed the value of the freehold property at 31 December 2025 and based on the movement in the property index for similar freehold properties in the local area in the last year consider it is reasonable to apply an uplift of 2% to the property value at 31 December 2025. Based on the carrying amount of £7,363k this has given rise to a gain on revaluation of £147k and a final year end value of £7,509k.

If the freehold property was stated using the historical cost model, the carrying amount recognised at 31 December 2025 would have been £7,188k.

11. Heritage assets

In addition to the assets outlined in note 10, the Institute owns a collection of paintings and artefacts of historic and scientific importance which is deemed to be heritage assets as defined under SORP (FRS 102). The collection comprises portraits, paintings, artefacts and sculptures, which the Institute has commissioned, acquired or received as a donation to either enhance the fabric of its building or to celebrate its history in science, engineering and technology.

The Institute maintains a comprehensive register of these assets. The Institute’s heritage assets were valued in February 2019 by Penny Bingham (MRICS), an independent Fine Art Valuer, at a combined value of £287k. The most valuable items (forming 70% of this collection by 2019 valuation) were revalued in April 2025 by Gurr Johns Ltd, with an average reduction of 37.5% from the previous valuation. This was taken as an indication of impairment to the whole collection at 31 December 2024 and the collection was recognised at the reduced value of £179k at 31 December 2024. The impairment loss of £108k was deducted from the revaluation reserve against previously recognised gains.

Separately, the Institute’s Mining Lamp collection was valued in May 2016 by David Rimmer of the Miners Lamp Society at a combined value of £169k. A new independent, specialist valuation of the lamps is being sought in 2026.

The independent valuers consider that the resale value of individual heritage assets is very sensitive to the number of potential purchasers with the ability and willingness to pay. Trustees have considered the valuation at 31 December 2025 and are satisfied it remains accurate.

22. Pension schemes

22.1 Introduction

The Institute operates a funded defined benefit occupational pension scheme. The assets of the scheme are held separately from those of the Institute and are invested in an insured fund administered by the Prudential Assurance Company Limited and Mobius Life Fund administered by Mobius Life Limited. Under the terms of the Trust Deeds, the scheme is administered by the Trustees.

The scheme was closed to new members during 2002 and closed to accrual on 31 December 2021. New employees are given the opportunity to join the group personal pension arrangements with Royal London. The group personal pension plan is a defined contribution benefit scheme and complies with the stakeholder legislation.

At the year end, the scheme had 49 deferred members.

Results of the most recent triennial actuarial valuations, at 1 January 2019, 2022 and 2025 showed the following results.
