FRS 102 is the principal financial reporting standard for companies, LLPs, charities, and other entities in the UK and Republic of Ireland that do not apply full IFRS. Issued by the Financial Reporting Council (FRC), it sets out how those organisations must recognise, measure, present, and disclose financial transactions in their accounts. The FRC estimates the standard affects around 3.2 million entities across the UK and Republic of Ireland, making it the backbone of UK GAAP.
If you work in finance for a private company, an LLP, a charity, or a housing association in the UK or Republic of Ireland, FRS 102 almost certainly governs how your financial statements are prepared. This guide explains what the standard covers, who it applies to, what it does not apply to, and what changed when the 2024 Periodic Review amendments came into effect on 1 January 2026. For background on how lease accounting specifically works under the new rules, our FRS 102 right-of-use asset guide covers the ROU asset mechanics in detail.
Updated May 2026.
FRS 102 governs the full scope of financial reporting for eligible entities: how revenue is recognised, how leases are accounted for, how financial instruments are measured, how business combinations are treated, how tax is presented, and how disclosures are structured. It covers all primary financial statements, including the balance sheet, profit and loss account, cash flow statement, and notes.
The standard is based on the IASB's IFRS for SMEs, but it has been adapted in material ways to reflect the legal requirements and practical circumstances of UK and Irish entities. It does not simply replicate full IFRS. The FRC reviews FRS 102 on approximately a five-year cycle, with each periodic review adjusting the standard to improve alignment with international practice where that alignment is proportionate.
The key sections finance teams encounter most frequently are:
Section 1A provides a separate set of reduced presentation and disclosure requirements for small entities. Small entities that qualify can apply Section 1A and benefit from meaningful simplifications, while still applying the full recognition and measurement requirements of FRS 102 in all other respects.
FRS 102 applies to any entity that prepares financial statements intended to give a true and fair view, operates within the UK or Republic of Ireland, and does not apply full IFRS or FRS 105. The standard covers companies, limited liability partnerships, charities, housing associations, pension schemes, public benefit entities, and subsidiaries using reduced disclosures under FRS 101. It applies to entities of all sizes, from small private companies to large unlisted groups.
In practical terms, the entities most commonly reporting under FRS 102 include:
Micro-entities that meet the qualifying size thresholds also have the option to report under FRS 102 Section 1A rather than FRS 105, if that better serves their stakeholders. Eligibility for the micro-entity regime does not require its use.
Three categories of entity fall outside FRS 102. Listed companies in the UK preparing consolidated financial statements must use full IFRS as adopted in the UK. Micro-entities that choose to apply the micro-entities regime must use FRS 105, a separate and more simplified standard. Subsidiaries and parent companies within certain groups may elect to apply FRS 101 (the Reduced Disclosure Framework), which uses IFRS recognition and measurement but with fewer disclosure obligations.
The dividing lines matter practically. A financial controller at a UK subsidiary of a listed group prepares individual entity accounts under UK GAAP (either FRS 102 or FRS 101) even though the parent reports under full IFRS. The group's consolidated statements use IFRS; the subsidiary's standalone statutory accounts do not.
How the UK and Irish reporting frameworks compare
| Standard | Who it applies to | Lease accounting from 2026 | Disclosure level |
|---|---|---|---|
| Full IFRS | UK-listed companies (consolidated accounts) | IFRS 16: all leases on-balance sheet | Full IFRS disclosures |
| FRS 102 | Private companies, LLPs, charities, housing associations, subsidiaries (UK/ROI) | New Section 20: most leases on-balance sheet (with some simplifications vs IFRS 16) | Full UK GAAP disclosures (reduced for Section 1A small entities) |
| FRS 105 | Micro-entities that choose to apply the micro-entities regime (turnover up to £1m, assets up to £500k, employees up to 10) | Unchanged: old finance/operating lease split still applies under FRS 105 | Minimal disclosures only |
Note that the micro-entity thresholds were increased from April 2025 under new government legislation: turnover up to £1 million (previously £632,000) and total assets up to £500,000 (previously £316,000). This means some entities that previously fell under FRS 102 may now qualify for FRS 105, though use of the micro-entities regime remains optional.
The FRC published the Periodic Review 2024 amendments on 27 March 2024, concluding its second full review of the standard. The primary aim was to bring UK GAAP into closer alignment with IFRS 15 (revenue recognition) and IFRS 16 (leases), improving comparability between UK and Irish entities and those reporting under international standards. A group finance team consolidating a UK subsidiary alongside IFRS-reporting entities in the same group previously had to reconcile two materially different lease accounting models; the 2024 changes narrow that gap.
The review was not about wholesale replacement of UK GAAP. It was deliberate and proportionate: bring FRS 102 into line with the economic substance of IFRS where that alignment improves transparency, while retaining simplifications that make the standard workable for entities without the resources and infrastructure of a listed company. The two areas most material to most finance teams are leases and revenue recognition.
The amended standard was issued in September 2024. Early adoption was permitted from 1 January 2025, provided all Periodic Review amendments were adopted together. For most organisations, mandatory application begins with accounting periods starting on or after 1 January 2026. For a December year-end, that means the first affected accounts will be for the year ending 31 December 2026.
Section 20 of FRS 102 was fundamentally rewritten: the old finance lease vs operating lease split is abolished for lessees, and almost all leases must now be recognised on the balance sheet as a right-of-use (ROU) asset and a corresponding lease liability, regardless of how they were previously classified. This applies to accounting periods beginning on or after 1 January 2026. For how the ROU asset itself is measured and depreciated, see the FRS 102 right-of-use asset guide.
The practical consequences are significant. For organisations with material lease portfolios, property, vehicles, and equipment that previously sat entirely off-balance sheet now appear as both assets and liabilities on the face of the balance sheet. Total assets increase, total liabilities increase, and key ratios shift. Net debt covenants, loan-to-value ratios, and EBITDA-based metrics all need reviewing against the new balance sheet position.
Two exemptions apply for lessees: short-term leases (original term of 12 months or less) and leases of low-value assets may be kept off-balance sheet. These are policy elections, not automatic treatments, and they must be applied consistently across asset classes. The definition of the lease term also now requires judgement: optional extension periods must be included in the lease term if the lessee is reasonably certain to exercise the option.
What changed: old Section 20 vs new Section 20
| Area | Old Section 20 (pre-2026) | New Section 20 (from 1 Jan 2026) |
|---|---|---|
| Lessee classification | Finance lease or operating lease (risks and rewards test) | Single model: right-of-use asset + lease liability for all leases (with two limited exemptions) |
| Operating leases | Off-balance sheet; straight-line expense in P&L | On-balance sheet (ROU asset + liability); interest and depreciation replace rental expense |
| Balance sheet impact | Minimal for operating lessees | Potentially material: all qualifying leases increase assets and liabilities |
| Exemptions available | N/A (classification-based) | Short-term leases (12 months or less); low-value asset leases |
The revised Section 23 aligns FRS 102 revenue recognition with the five-step model from IFRS 15: identify the contract, identify the performance obligations, determine the transaction price, allocate the price to each obligation, and recognise revenue when (or as) each obligation is satisfied. This replaces a less structured approach that relied on general principles and specific rules for different transaction types. For most straightforward businesses, the practical outcome is similar to before; for those with complex contracts, variable consideration, or multiple deliverables, the change is more significant.
Construction companies, software businesses, and professional services firms with multi-element arrangements are most likely to see the largest changes in timing of revenue recognition. Where revenue was previously recognised at delivery of a single milestone, it may now need to be allocated and recognised across multiple performance obligations within the same contract.
Retail businesses with twenty shop locations feel the Section 20 changes differently from a professional services firm with a single office lease. Both bring previously off-balance sheet operating leases onto the balance sheet, but the materiality differs dramatically. Retailers, transport and logistics operators, healthcare providers, and any organisation with large property or vehicle fleets will see the most significant balance sheet movements from the new lease rules.
For revenue recognition, the industries where the five-step model creates the most complexity are:
For any of these sectors, the 2026 changes are not just an accounting adjustment; they require a re-examination of contract structures, system capabilities, and financial reporting processes.
The Section 20 lease changes are operationally the most disruptive because they require data, not just accounting policy. Under the old model, an operating lease required only the total commitment and a straight-line charge; under the new model, every qualifying lease needs a full set of terms: commencement date, lease term (including options), initial direct costs, lease incentives, payment schedule, and the discount rate to be applied. That data needs to be gathered, validated, and maintained for every lease in the portfolio.
For organisations managing leases on spreadsheets, the calculation burden is considerable. Each lease generates an amortisation schedule for the liability and a depreciation schedule for the ROU asset. Modifications, rent reviews, and lease extensions each require remeasurement. The audit trail for every change needs to be maintained and auditable. This is where the volume of operational work diverges sharply from the accounting policy change itself: the policy is a paragraph; the implementation is months of work.

Does FRS 102 apply to charities?
FRS 102 applies to charities in the UK and Republic of Ireland that prepare accruals-based accounts, supplemented by the relevant Charities SORP (Statement of Recommended Practice). The Charities SORP adapts FRS 102 to the specific circumstances of the charity sector, including fund accounting, grant income, and donated goods. Smaller charities using the receipts and payments basis are not required to apply FRS 102. The 2024 Periodic Review amendments, including the new Section 20 lease requirements, apply to charities in the same way as to other FRS 102 entities.
Does FRS 102 apply to subsidiaries of listed groups?
A UK or Irish subsidiary of a listed group prepares its standalone statutory accounts under UK GAAP (FRS 102 or, where eligible, FRS 101) even if the parent company consolidates under full IFRS. The subsidiary's individual accounts follow FRS 102 unless the entity has elected FRS 101. The group's consolidated statements use IFRS; what the subsidiary uses for its own statutory filing is a separate decision. This is a common source of confusion for finance teams in multinational structures.
Can an entity adopt the 2024 amendments early?
Early adoption of the 2024 Periodic Review amendments was permitted for accounting periods beginning on or after 1 January 2025, provided all the amendments were adopted together rather than selectively. An entity could not, for example, early-adopt the new revenue recognition rules while retaining the old lease accounting. The FRC required a package approach to early adoption to maintain internal consistency within the financial statements. For most entities with a December year-end, mandatory application begins for the year ending 31 December 2026.
What is the difference between FRS 102 and FRS 105?
FRS 102 is the full UK GAAP standard applying to most entities in the UK and Republic of Ireland. FRS 105 is a separate, more simplified standard available only to micro-entities: companies with turnover up to £1 million, total assets up to £500,000, and no more than 10 employees (thresholds updated from April 2025). FRS 105 does not require on-balance sheet lease accounting; the old finance/operating lease split remains under FRS 105. A micro-entity can choose to use FRS 102 Section 1A instead of FRS 105 if that better serves its stakeholders.
Does FRS 102 apply to entities in the Republic of Ireland?
FRS 102 applies in both the UK and the Republic of Ireland. The standard is issued by the FRC with the endorsement of the Consultative Committee of Accountancy Bodies in Ireland (CCAB-I) and is the principal GAAP for Irish entities that do not apply EU-adopted IFRS. Irish companies listed on a regulated EU market must use EU-adopted IFRS for consolidated accounts; unlisted Irish companies and groups use FRS 102. The 2024 Periodic Review amendments apply equally to Irish entities from accounting periods beginning on or after 1 January 2026.
