📘FRS 102 Lease Accounting Disclosures: A Practical Guide for UK SMEs

Transition, disclosures, and Section 1A requirements explained clearly

Introduction

The 2024 revision of FRS 102 Section 20 (Leases) represents the most significant change to SME lease accounting in over a decade. From 1 January 2026, UK entities must adopt a right-of-use (ROU) model similar to IFRS 16 — bringing most leases onto the balance sheet.

For many SMEs, the challenge is not just calculation — it is understanding what must actually be disclosed in the financial statements.

This practical guide breaks down:

✅ What SMEs must disclose on transition

✅ What must be disclosed in a normal (post-transition) year

✅ What Section 1A small entities must disclose

All paragraph references come directly from the 2024 edition of FRS 102.

🔄 Transition-Year Disclosures

Transition requirements for leases are set out in paragraphs 1.44–1.54.

These apply in the first year an entity adopts the revised Section 20 — for a lot of SMEs, the year ending 31 December 2026.

From a practical perspective, transition disclosures should clearly explain what changed, how it was measured, and the financial impact.

📊 Required transition disclosures

✅ Effect on profit or loss

Entities must disclose the impact on profit or loss of applying the revised Section 20, or explain if impracticable. Reference: FRS 102 para 1.44(a)–(b)

✅ Transitional method

Entities must disclose the modified retrospective approach used and confirm that comparatives were not restated. Reference: FRS 102 paras 1.47–1.50

✅ Practical expedients

If used, entities must disclose expedients such as:

• Not reassessing whether a contract contains a lease (para 1.45)

• Using IFRS 16 carrying amounts (para 1.48)

• Portfolio discount rates, onerous-lease assessments, hindsight, etc. (para 1.53)

  
  

👉 Why this matters: Expedients can materially affect lease balances, so transparency is important.

✅ Measurement bases

Entities must disclose how they measured:

• Lease liabilities (para 1.51(a))

• ROU assets (para 1.51(b))

• Impairment or use of onerous-lease expedient (para 1.51(c))

👉 Keep this simple: Avoid boilerplate — briefly explain the methodology used.

✅ Opening equity adjustment

Entities must disclose the adjustment to opening retained earnings. Reference: FRS 102 paras 1.47–1.50

👉 This is often one of the first figures reviewers look for when assessing transition impact. In practice most transition journals will have an adjustment to the right of use asset as a result of lease incentives liability, accrued rent and/or prepaid rent positions.

📅 Ongoing FRS 102 Lease Disclosures (Section 20)

Once transition is complete, entities must comply with the full disclosure requirements in Section 20, particularly 20.80–20.116.

The objective is straightforward: enable readers to understand the scale of leasing activity and its financial effect.

🔢 Quantitative disclosures

• Movements in ROU assets (20.80–20.90)

• Movements in lease liabilities (20.110–20.115)

• Depreciation and interest expense (20.112)

• Variable lease payments (20.113)

• Short-term and low-value lease expenses (20.114)

• Maturity analysis of lease liabilities (20.116)

🧾 Qualitative disclosures

• Nature of leasing activities

• Significant terms (options, restrictions, residual value guarantees)

• Judgements such as lease term and discount rate. Reference: 20.100–20.109

👉 Focus on the judgements that genuinely affect measurement — avoid unnecessary volume. Ensure any areas of judgement are documented thoroughly should you require an audit. See Front Foot Finance's take on how to apply and document your discount rate.

🏢 Section 1A Small-Entity Lease Disclosures

Small entities applying Section 1A must still provide enough information for a true and fair view. Reference: FRS 102 paras 1A.5–1A.17

The regime is simplified — but it is not a disclosure exemption.

✅ Minimum required disclosures

Appendix C (UK) sets out the minimum disclosures small entities must provide. Reference: FRS 102 para 1A.16A

For leases, this typically includes:

• Total lease commitments

• Lease liabilities (if material)

• Narrative description of lease arrangements

• Any additional disclosures needed for a true and fair view (1A.16–1A.17)

⚠️ Small entities do not automatically get exemption from lease disclosures — material information must still be provided.

👉 Practical reality: If leases are significant to the balance sheet, additional explanation is usually expected.
