Understanding FRS 102 Lease Accounting Standards
Under the amended FRS 102 Section 20, most operating leases will move onto the balance sheet.
The changes apply to accounting periods beginning on or after 1 January 2026.
What Changes at Transition Date
Instead of recognising rental expense on straight-line basis, entities will recognise a lease liability measured at the present value of future lease payments and a corresponding right-of-use asset.
At transition, existing operating leases will be brought onto the balance sheet using the modified retrospective approach, requiring:
• Determination of the lease term
• Identification of lease payments to include
• Selection and support of an appropriate discount rate
• Calculation of opening lease liability and right-of-use asset
• Consideration of any impact on retained earnings
• Consideration of practical expedients including short-term and low-value exemptions
What Changes after Transition Date
Subsequently, the lease liability will unwind using the effective interest method and the ROU asset will be depreciated over the shorter of the lease term or remaining useful life.
What Changes at Year-End Reporting
At the end of the reporting period, FRS 102 now requires certain disclosures including a:
• Description of nature of leasing arrangements and significant terms
• Disclosure of key judgements
• Disclosure of profit or loss lease amounts (depreciation and interest expense)
• Table of movements in ROU assets and lease liabilities
• Disclosure of short-term and low-value lease expenses
In the first year of application there are additional transition disclosures including a:
• Disclosure of the impact on profit or loss of applying the revised standard
• Disclosure of the application of the modified retrospective approach
• Disclosure of any practical expedients applied
How Will Lease Accounting Changes Impact SMEs and Accountancy Firms?
What Will Change For Businesses
- Bigger reported debt & weaker leverage ratios – Gearing/net debt metrics look higher and can affect lender and investor conversations.
- EBITDA uplift – Rent expense is replaced by depreciation + interest, so EBITDA increases mechanically.
- Tax profile may shift – Rent expense is replaced by depreciation+ interest; tax deductions follow that pattern changing the timing of taxable profits.
- More work, more data, more judgement – You’ll need a reliable lease schedule, clear assumptions, ongoing updates for remeasurements/modifications and extra year-end disclosures.
What The Amendment Means in Practice
For most SMEs and their advisers, the ongoing requirement becomes a structured, repeatable year-end process.
✓ One structured lease model per lease
✓ Documented discount rate rationale
✓ Annual interest unwind and depreciation update
✓ Standardised disclosure note
✓ Clear audit trail for assumptions and calculations
Impact on Accounting Firms
- Higher Volume of Calculations – Multiple client lease models requiring consistency.
- Documentation & Audit Trail – Clear support for discount rates, lease terms and assumptions.
- Recurring Annual Updates – Ongoing recalculation and disclosure preparation.
- Audit Scrutiny – Greater focus on assumptions and methodology.

Frequently Asked Questions on FRS 102 Lease Transition
Why is the FRC introducing this change to lease accounting?
The FRC is seeking to improve transparency and comparability by bringing operating leases onto the balance sheet. This better reflects the economic substance of long-term lease commitments and aligns FRS 102 more closely with international practice.
What discount rate should be used?
If you cannot readily determine the interest rate implicit in the lease the lessee shall choose, on a lease‑by‑lease basis, to apply either the lessee’s incremental borrowing rate or the lessee’s obtainable borrowing rate (20.49).
Can a portfolio discount rate be applied?
A lessee may apply Section 20 to a portfolio of leases with similar characteristics (20.13). This allows SMEs to use estimates and assumptions at a portfolio level, reducing administrative burden.
What is the modified retrospective approach?
Under the modified retrospective approach, comparative periods are not restated. Instead the cumulative impact of applying FRS 102 is accounted for as an adjustment to equity at the start of the current accounting period in which it is first applied.
