Most UKI finance teams are now preparing for the revised FRS 102 leasing requirements coming into effect from 2026. Under the previous framework, many operating leases sat off the balance sheet, but the updated approach now brings them directly into the primary financial statements as both a lease liability and a right-of-use (ROU) asset. This increases the level of measurement, judgement, and ongoing monitoring required from finance teams and places greater focus on how lease portfolios are managed.

In practice, this means finance teams must now evaluate whether their current systems and processes can support the updated requirements, particularly where lease data, calculations, and modifications will need to be applied consistently throughout the year.

What exactly is changing in the revised FRS 102 lease model?

The revised Section 20 of FRS 102 introduces a new right-of-use lease accounting model for lessees, effective for periods beginning on or after 1 January 2026. This replaces the previous operating-lease/finance-lease distinction and brings most leases onto the balance sheet.

While the revised model aligns closely with IFRS 16 in principle, the UK GAAP version remains distinct.

Key differences include:

• A modified retrospective transition approach, with a practical expedient for entities that already hold IFRS 16 lease balances for group reporting
• UKI-specific formats, especially for Section 1A small entities
• Additional legal disclosures required under Appendix C for UKI small companies
• Simplified options and exemptions tailored to UK GAAP preparers

In short, the updated FRS 102 applies familiar principles but within a uniquely UKI framework, and any supporting software must reflect those UKI-specific requirements.

Why is using spreadsheets or generic, non-UK GAAP lease software risky under the revised FRS 102?

Spreadsheets and generic non-UK GAAP lease software do not automatically apply the UK-specific rules and transition requirements introduced in the revised FRS 102. As a result, finance teams often need manual workarounds to meet the updated model, which leads to several accounting and audit risks, such as:

1. Misaligned accounting treatments

Many generic systems are designed around rigid rule sets (often more aligned with US GAAP), rather than the more principles-based choices FRS 102 allows. Under the revised FRS 102, UKI companies will have the ability to choose many aspects on exactly how the accounting standard should be applied. Organisations should not be dictated on what they can and cannot post for their lease accounting based on their choice of accounting system.

2. New data gathering requirements

For many organisations, the initial data collection of the leasing portfolio details will represent the hardest and most time-consuming part of the transition process. This is because organisations are required to find and categorise data points they have not previously reported, and subjective decisions will need to be made on a lease by lease basis which can’t always be found on the leasing contract.

3. Confusion caused by US GAAP-centric terminology

Finance teams end up translating US GAAP terms into UK GAAP equivalents, slowing down close processes and increasing audit queries.

4. Spreadsheet dependency and error risk

Teams often compensate with spreadsheets, which are prone to formula errors, version control problems and audit trail limitations, particularly under re measurements, index-linked increases and partial terminations.

5. Audit delays

Auditors frequently request UK-GAAP-formatted support. When system reports do not match UKI formats, teams must rebuild calculations manually, adding pressure to already tight reporting cycles.

How can FRS 102-ready software support finance teams under the updated leasing model?

UK GAAP reporters need software designed specifically for FRS 102 as the revised leasing requirements introduce UKI-specific recognition, measurement and disclosure requirements that must be applied consistently throughout the life of each lease. The model requires structured processes for discounting, transition, reassessment and remeasurement, along with UKI-aligned reporting outputs and audit evidence. At the same time, flexibility is required in the generation of the accounting entries, and how and when these are applied.

Purpose-built FRS 102 software provides the workflows and calculation logic needed to support the updated standard in practice. This support is most visible in areas such as:

• Capturing renewals, rent-free periods, CPI-linked increases
• Handling partial terminations and mid-term modifications
• Managing multiple entities across a UKI group
• Matching lease schedules to the UKI chart of accounts
• Reducing friction with auditors

Together, these capabilities give finance teams a more controlled, consistent and audit-ready way to manage leases under the updated FRS 102 model.

A practical next step for UK GAAP reporters

Moving to the revised FRS 102 lease model represents both a compliance requirement and an opportunity to strengthen control, improve efficiency and reduce manual work across the lease portfolio. For many organisations, FRS 102-ready lease accounting software is now the most reliable way to manage the new model with consistency and confidence.
