Lease Accounting Under FRS 102 (2026 Changes): A Practical Guide

Lease accounting under FRS 102 — the main accounting standard for UK and Irish entities that don't apply full IFRS — is changing significantly. A periodic review of FRS 102 has introduced a new, on-balance-sheet model for leases, bringing it much closer to IFRS 16. This practical guide explains how lease accounting has worked under FRS 102, what is changing, when it applies, how to prepare, and why it matters — in plain language. It's an important topic for accountants applying UK GAAP. (Always check the latest version of FRS 102 and the effective dates for authoritative requirements.)

What is FRS 102?

FRS 102 is the principal UK and Ireland GAAP standard — the financial reporting standard applied by many entities that are not required, or do not choose, to apply full IFRS. It provides a single, somewhat simplified framework for preparing financial statements, and it's reviewed periodically by the Financial Reporting Council (FRC) to keep it up to date and broadly aligned with international standards where appropriate.

How lease accounting worked under FRS 102

Historically, FRS 102 took a different approach to leases from IFRS 16. For lessees, it retained the older-style distinction between:

• Finance leases — where the risks and rewards of ownership substantially transfer to the lessee. These were recognised on the balance sheet (as an asset and a liability).
• Operating leases — all other leases. These were kept off the balance sheet, with the rentals simply charged to profit or loss, usually on a straight-line basis.

This was similar to the old IAS 17 approach — and notably different from IFRS 16, which had already moved listed companies to an on-balance-sheet model for nearly all leases.

What is changing

Following its periodic review, the FRC has issued amendments to FRS 102 that introduce a new on-balance-sheet lease model for lessees, aligned with the approach of IFRS 16 (but with some simplifications appropriate to FRS 102 entities). Under the new model, lessees will generally recognise a right-of-use asset and a lease liability for their leases — ending the previous off-balance-sheet treatment of operating leases. Practical exemptions, such as for short-term and low-value leases, are expected to keep the change proportionate.

When does it apply?

The amendments are effective for accounting periods beginning on or after 1 January 2026, with early application generally permitted. Because the change brings previously off-balance-sheet leases onto the balance sheet, affected businesses need to prepare — identifying their lease arrangements, gathering the necessary data, and considering the impact on their financial statements and on measures such as gearing. As always, the precise requirements and effective date should be confirmed against the latest version of the standard.

How to prepare

Businesses and their accountants can take practical steps ahead of the change: identify all lease arrangements, including ones currently treated as operating leases that may now come on balance sheet; gather the data needed to measure them (lease terms, payments, and an appropriate discount rate); assess the impact on the balance sheet, profit profile and any loan covenants or ratios that could be affected; consider the exemptions for short-term and low-value leases; and update systems and processes to capture lease information going forward. Starting early avoids a last-minute scramble and helps manage any knock-on effects with lenders or stakeholders.

Why it matters

This change matters because it significantly affects how UK GAAP entities report their leases — bringing greater transparency and comparability, and aligning FRS 102 more closely with IFRS 16. For affected businesses, the move can have a real effect on the balance sheet, key ratios and the way performance is presented. For accountants applying FRS 102, understanding the new lease model — and helping clients or employers prepare for it — is an important and timely area of knowledge.
