FRS 102 Update 2026: Key Changes from the Triennial Review for UK Accountants

The FRS 102 Triennial Review: What Changed in 2026

The Financial Reporting Council's (FRC) triennial review of FRS 102 introduced significant amendments effective for accounting periods beginning on or after 1 January 2026 (with early adoption permitted from 1 January 2025). These are the most substantial changes to FRS 102 since it was introduced in 2015 and affect virtually every entity applying the standard. Finance professionals working with UK GAAP accounts need to understand these changes and their practical implications.

Revenue Recognition: Alignment with IFRS 15

Section 23 of FRS 102 has been substantially rewritten to align with IFRS 15's five-step model. The key practical changes: identifying performance obligations in contracts (now required rather than optional), variable consideration — revenue can only be recognised to the extent it is highly probable there will not be a significant reversal, and the concept of "point in time" vs "over time" recognition is now more explicitly codified. For many entities this change will be familiar from IFRS 15 exposure, but for entities that were applying the old risks-and-rewards model, adjustment will be required.

Lease Accounting: Right-of-Use Asset Model

Section 20 has been amended to introduce a right-of-use asset model similar to IFRS 16 for lessees with qualifying leases. Short-term leases (12 months or less) and low-value asset leases remain off-balance-sheet. This is the most impactful change for entities with significant operating lease portfolios — property-heavy businesses, retailers, and professional services firms will see balance sheets grow substantially as operating leases are brought on. The transition adjustment (bringing existing leases on balance sheet on adoption) is a practical priority for 2025 and 2026.

Other Significant Changes

Financial instruments: enhanced guidance on measurement of financial assets and liabilities, with some alignment toward IFRS 9 principles. Disclosures: updated and expanded disclosure requirements across multiple sections. Investment property: further guidance on the cost-depreciation-impairment model for entities that do not use fair value.

Transition: Practical Steps

Entities should: identify all operating leases in scope of the new lease model, collect lease data (term, payments, extension options), determine the incremental borrowing rate for discounting, calculate the opening right-of-use asset and lease liability, and prepare the transition note disclosure. For small entities considering moving to FRS 105 (micro-entities) to avoid the new requirements, check eligibility carefully.
