We hosted a Professional Review Assessor Workshop at IGEM House for Engineering Technician (EngTech MIGEM), Incorporated (IEng MIGEM), and Chartered (CEng MIGEM) members volunteering to become IGEM approved Assessors. The workshop was extremely well received and proved highly successful. In addition, we delivered a dedicated Professional Review Assessor Webinar for our Far East District Section, ensuring existing Assessors remained up to date while training new Assessors.

Alongside these activities, we delivered a series of professional registration webinars open to prospective members and those seeking to transfer grades, as well as in-house webinars and exhibitions supported by our Company Members. Our online 1:1 booking system has also continued to provide valuable, personalised guidance for individuals exploring their pathway to membership and professional registration.

Our new members continued to benefit from our New Member Welcome Meetings, which provide a comprehensive introduction to membership services and benefits. These sessions offer insights into the MyIGEM portal, Hydrogen Knowledge Centre, Section membership, and the range of support available to help members plan and record their Continuing Professional Development (CPD).

To prepare for an increase in the CPD sample size to 5% from 2026 onwards, we contacted over 100 of our professionally registered members for our 2025 annual CPD sampling and once again recorded a new high in CPD submissions. Thanks to the support of IGEM members and their engagement with the CPD sampling process, we successfully sampled 4.1% a CPD record, to support their professional development and future goals. Those that did not submit a record will be offered additional support in order to enable them to provide a submission for 2026. This year no members were removed from the national Engineering Council register due to non-compliance.

We had another successful year with our Scholarships, Grants and Awards scheme. The scheme continues to support the engineers of the future, and this year we awarded two Prospective Undergraduate Scholarships, two current Undergraduate Scholarships and one Engineering Technician Grant.

IGEM develops and produces Technical Standards with related activities including research, record management, training and liaising with industry and external stakeholders. Selected standards are made available for a reduced rate through the Gas Safe Register. This supports operatives working in the downstream sector to enable more industry representatives to have affordable access to Standards.

Working with the technical committees, expert panels and working groups, members and volunteers were involved in 117 meetings, resulting in the department producing 259 technical papers and publishing 8 standards throughout the year, these were:

hydrogen standards continued in 2025. Through the Hydrogen Committee, chaired by Keith Owen of Northern Gas Networks (NGN), the Committee continues to grow in strength, working on the strategic plan with key stakeholders on a range of research and demonstration projects investigating the role of hydrogen.

Work also began on a new major funded project on a comprehensive revision of the Hydrogen transmission standards, focusing on incorporating recent research, industry collaboration, and addressing fracture and fatigue assessment for high pressure hydrogen pipelines.

IGEM also continued to support the OFGEM funded project led by SGN and partnering with the gas networks, National Gas and DNV on the Velocity Design with Hydrogen Project. This project will demonstrate safe velocity limits for hydrogen, and hydrogen blends, with focus on erosion, vibration, noise, and particle transportation. This project will conclude in 2026 and will provide key information for updates to the IGEM standards.

Significant progress was made during the year on the new IGEM/H/4 hydrogen quality standard chaired by Dr Martin Brown from DNV. The panel continues to be well supported by members from GDNs, Progressive Energy, Storengy, ITM Power, GERG, ICOM, HHIC, Ofgem, HSE and Policy/Technical leads from DESNZ.

The annual programme of events then continued with ongoing strong performance. Amongst these events was The Gas Utilisation Conference, the only dedicated downstream engineering conference meeting the downstream members needs with an engaging programme of speakers.

The Gas Industry Awards in conjunction with EUA was held in May, and a record audience for recent years heard a keynote address from Simon Virley CB FEI, Vice Chair and Head of Energy and Natural Resources at KPMG, ahead of host Jo Caulfield announcing the winners of the twelve categories.

The Policy Conference in June welcomed an estimated 40% increase in attendance, with attendees hearing from a wide range of speakers, with the programme designed around the Gas Policy : Time To Act theme, with sessions looking at Realising the Potential of Biomethane, Hydrogen Blending, End User Technology and Role of Gas in Clean Power 2030 Mission.

We closed the year out with the Annual Conference, with a theme of 'Pushing the Boundaries', which had a packed programme for the increased audience, that was mix of presentations, and panel discussions looking at Leading through the energy transition, System operations - navigating through uncertainty, Growing and creating capacity for biomethane, Enablers for the energy transition and Delivering hydrogen pipelines and CCS for industrial clusters.

almost 35% of the events dedicated to training on the technical standards we continue to provide essential learning opportunities for IGEM members and non-members to ensure the industry continues to provide a safe and secure gas network.

We also launched an updated Beach to Burner course, aimed at those new to the industry which, with sell-out attendance in November, lead to bookings for in-house and public courses for later into 2026, showing we are meeting training needs for our members and the industry.

Outside of the annual calendar IGEM also had presence at various industry events such as the CO Research Conference, Utility Week Live, and Political Party Conferences to name a few.

Reserves

developments to benefit members, customers and support the gas industry in a viable and sustainable manner. The Development Reserve is for future investment into the development of the Institution and to facilitate the investment into the energy transformation that is facing the industry.

With Council approval in September 2025, funding was provided to enable IGEM to work towards Cyber Essentials Certification, a UK government-backed scheme designed to help organisations protect against common online threats. Certification demonstrates a baseline level of cybersecurity and is increasingly recognised as a mark of credibility, particularly in technical and regulated industries. Importantly, this initiative directly supports one of the key mitigations r for IT, specifically in relation to data security and cyber threat exposure. This certification has successfully been achieved in January 2026.

With Council approval, the audio-visual (AV) equipment and infrastructure have been renewed across IGEM House, to provide better connectivity, support modern meeting demands, improve client experience, and maintain Meetpoint egworth and surrounding areas.

The General Reserve is the free reserve, held at a value of up to approximately six months expenditure, held at £1,300,000 for the institution, which provides adequate resilience to maintain liquidity and mitigate risks. The Restricted Funds were repurposed to enable increased application of the funds in order to make proper use of them in line with their objectives.

Total funds held by the group at the end of the reporting period are £5,270,279. This is constituted of general, designated and restricted funds as detailed below.

THE INSTITUTION OF GAS ENGINEERS AND MANAGERS YEAR ENDED 31 DECEMBER 2025

TRUSTEES EPORT (CONTINUED)

The amount of reserves freely available to the charity, after allowing for restricted funds, committed expenditure, assets and designations are therefore greater than six months of expenditure and is in line with the reserve policy.

Further details of the funds held are included in Notes 19 and 20 to these financial statements.

Risk Management

The Audit & Risk Committee is responsible for providing a robust risk management framework with effective controls that are integrated to the operational management of the Institution. The committee oversees quality management and governance processes including health, safety and environment, quality assurance management system that complies with BS EN ISO 9001:2015 standard and also a comprehensive risk register to identify, monitor and improve controls embedded within the organisation. The risk register has undergone a full review and has been simplified into a new format that has dashboard views for headline risks.

Strategies for managing these risks include the maintenance of identified processes that specifically mitigate the risk and a regularly reviewed action plan that is considered to provide further mitigation.

The Secretariat are responsible for the identification of risks and the effectiveness of management action to mitigate adverse performance against the Business Plan.

The detailed planning and execution of objectives and actions, resulting from risk reviews, are managed at an operational level within the Secretariat and are overseen by the Executive Board. There is an integrated management system that links risks, strategies, objectives and actions, managed by the Chief Executive Officer.

As a part of the requirements of this Standard, internal audits have to be undertaken. There are four member auditors, sitting on Audit & Risk Committee and two staff auditors. There were eight audits planned and all have been completed in 2025. We also completed a deep dive into the risk register. The review resulted in six changes to the risk scores in which all were lowered. There were six risks reviewed which resulted in no change to risk score. Two risks were considered opportunities for improvement and removed from the risk register but entered on to the opportunities register.

Lloyds Register Quality Assurance is our Accreditor and there was a recertification audit completed in June. The two non-conformances from the last audit were closed off and no new non-conformances were raised. The audit outcome -20I5.

Provision of Information to the Auditor

So far as each of the Trustees are aware at the time the report is approved:

The Trustees have taken all steps that they ought to have taken to make themselves aware of any relevant audit information and to establish that the auditors are aware of that information.

This report was approved by the Council on 18 March 2026 and signed on its behalf.

The Trustees are responsible for preparing the Trustees' Annual Report and the financial statements in accordance with applicable law and United Kingdom Accounting Standards (United Kingdom Generally Accepted Accounting Practice).

The law applicable to charities in England and Wales requires the Trustees to prepare financial statements for each financial year, which give a true and fair view of the state of affairs of the charity and of the incoming resources and application of resources of the charity for that period. In preparing these financial statements, the Trustees are required to:

The Trustees are responsible for maintaining proper accounting records, which disclose with reasonable accuracy at any time the financial position of the charity and to enable them to ensure that the accounts comply with the Charities Act 2011, the Charity (Accounts and Reports) Regulations 2008 and the provisions of the trust deed. They are also responsible for safeguarding the assets of the charity and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

OF THE INSTITUTION OF GAS ENGINEERS AND MANAGERS

Opinion

31 December 2025 which comprise the consolidated statement of financial activities, the consolidated and charity balance sheets, the consolidated statement of cash flows and notes to the financial statements, including significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including FRS 102 The Financial Reporting Standard applicable in the UK and Republic of Ireland (United Kingdom Generally Accepted Accounting Practice).

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 charity in accordance with the ethical requirements that 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

accounting in the preparation of the financial statement is appropriate.

Based on the work we have performed, we have not identified any material uncertainties relating to events or 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.

Other information

The other information comprises the information included in the annual report other than the financial statements and statements. 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.

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 course of 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.

16

OF THE INSTITUTION OF GAS ENGINEERS AND MANAGERS

Matters on which we are required to report by exception

In the light of the knowledge and understanding of the charity and its environment obtained in the course of the audit, we have not identified material misstatements in the Trustees' report. We have nothing to report in respect of the following matters where the Charities Act 2011 requires us to report to you if, in our opinion:

Responsibilities of Trustees

As explained more fully in the Trustees' responsibilities statement, the Trustees 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.

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 charity 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 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 charitable company and the industry in which it operates, we identified that the principal risks of non-compliance with laws and regulations related to the acts by the charitable company, which were contrary to applicable laws and regulations including fraud, and 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. We evaluated of override of controls), and determined that the principal risks were related to completeness of income for the year.

Audit procedures performed included:

17

OF THE INSTITUTION OF GAS ENGINEERS AND MANAGERS

There are inherent limitations in the audit procedures described above and the further removed non-compliance with laws and regulations is from the events and transactions reflected in the financial statements, the less likely we would become aware of it. Also, the risk of not detecting a material misstatement due to fraud is higher than the risk of not detecting one resulting from error, as fraud may involve deliberate concealment by, for example, forgery or intentional misrepresentations, or through collusion.

A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting

Use of our report

Act 2011 and regulations made under section 154 of that Act. Our audit work has been undertaken so that we might 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 for our audit work, for this report, or for the opinions we have formed.

THE INSTITUTION OF GAS ENGINEERS AND MANAGERS NOTES TO THE FINANCIAL STATEMENTS YEAR ENDED 31 DECEMBER 2025

1 ACCOUNTING POLICIES

(a) Basis of preparation and assessment of going concern

The financial statements have been prepared under the historical cost convention, as modified by the inclusion of fixed asset investments at market value. The financial statements have been prepared in accordance with the second edition of the Charities Statement of Recommended Practice issued in October 2019, the Financial Reporting Standard applicable in the United Kingdom and Republic of Ireland (FRS 102) and the Charities Act 2011.

The Institution constitutes a public benefit entity as defined by FRS 102.

The Trustees consider that there are no material uncertainties about the Institution going concern.

There are no significant areas of adjustment or key assumptions that affect items in the accounts.

(b) Group financial statements

These financial statements consolidate the results of the charity, its wholly-owned subsidiaries, IGEM House Ltd and IGEM Future Energy Networks Ltd; and the Scholarships, Medals, Prizes and Lectureship Fund, the History Fund and the Institution of Gas Engineers (Scottish Section) Benevolent and Education Funds, which are separate charities, on a line by line basis. A separate Statement of Financial Activities (SOFA) for the Institution alone is not presented because the charity has taken advantage of the provisions to not disclose.

(c) Funds accounting

Funds held by the charity are:

Unrestricted general funds - these funds can be used in accordance with the charitable objects at the discretion of the Trustees.

Designated funds - these are funds set aside by the Trustees out of unrestricted general funds for specific future purposes or projects.

Restricted funds - these funds can only be used for particular restricted purposes within the objects of the charity. Restrictions arise when specified by the donor.

(d) Incoming resources

All income is recognised once the charity has entitlement to the income, it is probable that the income will be received and the amount of income receivable can be measured reliably.

Voluntary income is accounted for when received. Incoming resources represents the amount receivable during the year in respect of subscriptions, fees and other income.

Dividends are recognised once the dividend has been declared and notification has been received of the dividend due. This is normally upon notification by our investment advisor of the dividend yield of the investment portfolio.

Where income is received in advance of performance, its recognition is deferred and included in creditors until the contract is performed. Membership subscriptions received in advance are deferred and included in creditors.

23

THE INSTITUTION OF GAS ENGINEERS AND MANAGERS NOTES TO THE FINANCIAL STATEMENTS (CONTINUED) YEAR ENDED 31 DECEMBER 2025

1 ACCOUNTING POLICIES (continued)

(e) Resources expended

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. Expenditure is classified under the following activity headings:

Irrecoverable VAT is charged as a cost against the activity for which the expenditure was incurred.

(f) Tangible Fixed Assets and Depreciation

Individual fixed assets costing £1,000 or more are capitalised at cost.

Depreciation is not charged on freehold land. Depreciation on other tangible fixed assets is provided to write off the cost of fixed assets to their residual value evenly over their estimated useful lives, which are as follows:-

Freehold property 50 years
Fixtures & Fittings 7 years
Computer equipment 3 years

(g) Foreign currencies

Monetary assets and liabilities denominated in foreign currencies are translated into sterling at rates of exchange ruling at the balance sheet date.

Transactions in foreign currencies are translated into sterling at the rate ruling on the date of the transaction.

Exchange gains and losses are recognised in the statement of financial activities.

(h) Investments

Investments are a form of basic financial instrument and are initially recognised at their transaction value and subsequently measured at their fair value as at the balance sheet date using the closing quoted market price. The statement of financial activities includes the net gains and losses arising on revaluation and disposals throughout the year.

The charity does not acquire put options, derivatives or other complex financial instruments.

The main form of financial risk faced by the charity is that of volatility in equity markets and investment markets due to wider economic conditions, the attitude of investors to investment risk, and changes in sentiment concerning equities and within particular sectors or sub sectors.

(i) Realised gains and losses

All gains and losses are taken to the Statement of Financial Activities as they arise. Realised gains and losses on investments are calculated as the difference between sales proceeds and their opening carrying value or their purchase value if acquired subsequent to the first day of the financial year. Unrealised gains and losses

24

THE INSTITUTION OF GAS ENGINEERS AND MANAGERS NOTES TO THE FINANCIAL STATEMENTS (CONTINUED) YEAR ENDED 31 DECEMBER 2025

1 ACCOUNTING POLICIES (continued)

(i) Realised gains and losses (continued)

are calculated as the difference between the fair value at the year-end and their carrying value. Realised and unrealised investment gains and losses are combined in the Statement of Financial Activities.

(j) Heritage assets

The Institution possesses a collection of regalia and memorabilia, and a collection of library books. heritage assets.

Where heritage assets are donated, the Trustees consider that in the absence of reliable cost information, the expense of determining a reliable valuation of these artefacts is onerous compared with the additional benefit derived by users of the accounts in assessing the T assets are gifted and are therefore excluded from the balance sheet in accordance with paragraph 18.14 of the SORP. Where heritage assets are purchased, the purchase costs are capitalised in the balance sheet.

(k) Cash and cash equivalents

Cash and cash equivalents include cash at bank and cash in hand as well as short-term highly liquid investments with a short maturity (recognised within short-term investments).

(l) Pensions

The Institution makes payments to defined contribution pension schemes on behalf of qualifying employees. Such contributions are charged in the Statement of Financial Activities when made. The contributions are sets.

(m) Operating leases

Operating lease rentals are charged on a straight-line basis over the lease term.

(n) Corporation tax

The charity is exempt from tax on income and gains falling within section 505 of the Taxes Act 1988 or section 252 of the Taxation of Chargeable Gains Act 1992 to the extent that these are applied to its charitable objects. However, one of the subsidiaries has elected to not gift-aid any surplus to the parent charity and as such, incurs

(o) Government grants

Government grants are recognised at the fair value of the asset received or receivable when there is reasonable assurance that the grant conditions will be met and the grants will be received.

A grant that specifies performance conditions is recognised in income when the performance conditions are met. Where a grant does not specify performance conditions it is recognised in income when the proceeds are received or receivable. A grant received before the recognition criteria are satisfied is recognised as a liability.

(p) Judgements in applying accounting policies and key sources of estimation uncertainty

In preparing these financial statements, the Trustees consider that there are no material judgements or estimates.

The Institution initially identifies the costs of its support functions. It then identifies those costs that relate to the governance function. Having identified its governance costs, the remaining support costs together with the governance costs are apportioned between the five key charitable activities undertaken (see note 6) in the year, based on the income generated for these charitable activities.

12. TANGIBLE FIXED ASSETS (continued) Regalia, memorabilia and library collection of books Heritage assets

The Institution has in its possession items gifted to it that comprises of regalia, memorabilia and a library collection of books, which have historical qualities and are held principally for their contribution to knowledge and therefore met the criteria for heritage assets.

These assets have not been included on the balance sheet as the information on their cost or valuation is not available, as these items were gifted to the Institution, and the information cannot be obtained at a cost commensurate with the benefit derived from obtaining this information. This is due to these items being unique and therefore a market value cannot be obtained, as their value would differ dependent on the user.

These regalia and memorabilia items are insured at a cumulative value of £327,986 (2024: £322,567). While the collection of library books has an insurance value of £71,350 (2024: £67,593).

13. INVESTMENTS (continued)

Holdings in excess of 5% of the total market value:

Rathbones Core Investment Fund for Charities 99.5%

IGEM House Ltd, a wholly owned subsidiary of the Institution, was incorporated to carry out the commercial activities of the Institution.

IGEM Future Energy Networks Ltd, a wholly owned subsidiary of the Institution, was incorporated to carry out the management of the transition towards building the energy networks of the future.

All investments are carried at their fair value. Investment in equities and fixed interest securities are all traded in quoted public markets. Holdings in common investment funds, unit trusts and open-ended investment companies are at the bid price. The basis of fair value for quoted investments is equivalent to the market value, using the bid price. Asset sales and purchases are recognised at the date of trade at cost (that is their transaction value).

The main risk to the Institution from financial instruments lies in the combination of uncertain investment markets and volatility in yield.

Liquidity risk is anticipated to be low as all assets are traded and the commitment to intervention by central banks and market regulators has continued to provide for orderly trading in the markets and so their ability to buy and sell quoted equities and stock is anticipated to continue. The Institution investments are mainly traded in markets with good liquidity and high trading volumes.

The Institution has no material investment holdings in markets subject to exchange controls or trading restrictions. The Institution does not make use of derivatives and similar complex financial instruments as it takes the view that investments are held for their longer-term yield total return and historic studies of quoted financial instruments have shown that volatility in any particular 5-year period will normally be corrected.
