FRS 102 Lease Accounting: IFRS 16 Explained for UK Finance Teams

The landscape of lease accounting has changed forever. Whether you report under IFRS 16 or are preparing for the upcoming FRS 102 (Section 20) amendments, the era of "off-balance-sheet" financing is ending. This guide breaks down the technical requirements into actionable steps.

What is IFRS 16?

IFRS 16 represents the biggest change to accounting standards in a generation. It requires lessees to recognize almost all leases on the balance sheet as of the commencement date, creating a Right-of-Use (ROU) Asset and a corresponding Lease Liability.

This ensures transparency, but it also increases the volatility of the P&L as rent is replaced by interest and depreciation. It's critical to understand the transition impact on your opening balance sheet.

FRS 102 (2026) Amendments

The FRC has recently aligned FRS 102 with the IFRS 16 model. For UK SMEs, this means the simplified operating lease accounting is being phased out. Preparation must start now to avoid year-end restatement shocks, especially regarding short-term lease exemptions and low-value asset exemptions which still apply under certain conditions.
