New Year, New Accounting: your practical roadmap for new FRS 102

Publications

Major changes to compliance for UK businesses are almost here. With the amended FRS 102 accounting standard becoming mandatory for periods beginning on or after 1 January 2026, the transition window for companies is shrinking. The good news is that with the right plan in place, your core work can be delivered in good time for reporting under the new rules in 2026.

Read on for a reminder of what’s changing, our recommended six-step roadmap for getting your systems and processes ready, and how our FRS 102 experts can help you.

Recapping the changes

The new FRS 102 will put almost all leases on your balance sheet and change when revenue is recognised. Your EBITDA will change, your balance sheet will change, and your disclosures will grow.

Every company preparing FRS 102 accounts, including small companies, must adopt the changes. With good preparation, the financial impact can be managed and communicated clearly to lenders, investors and boards.

While leases and revenue dominate the headlines, remember other amendments will also require attention.

Watch our video series for an overview of what’s changing under FRS 102, with focuses on lease accounting and revenue recognition.

Your transition roadmap

To break down your transition into a manageable process, we recommend following these six steps.

Step 1: Scoping 

The foundation of a smooth transition is identifying exactly what is affected.

  • Identify affected entities and contracts. If your business has significant lease arrangements or complex revenue contracts, you should begin this as soon as possible
  • Assess practical expedients for transitional or ongoing benefit, such as exemptions for short-term leases (12 months or less) and low-value assets

Step 2: Gathering data

Your finance team will need more granular information than before.

  • Compile data on lease terms, renewal options, variable rents, revenue contracts, performance obligations and termination rights

Completing this repository early will save you time and uncertainty later. It will also enable accurate transition calculations as your next step.

Step 3: Transition calculations

This is where technical adjustments are determined.

Key judgements and estimates are made at this stage and should be fully documented, as accuracy here underpins audit readiness.

  • Calculate and recognise lease liabilities at present value, and right-of-use assets applying chosen expedients

  • Reassess revenue timing under revenue timing under the new five-step model (listed in our article here) focussing on transfer of control, and calculate any tax or deferred tax impacts

Step 4: Tax impacts

The amended FRS 102 will create new temporary differences.

  • Align deferred tax adjustments with year-end computations

Step 5: Systems & controls

  • Transition changes must be embedded operationally, including any updates to ERP tools for lease postings and revenue tracking
  • Consider automation tools for lease management to reduce manual errors
  • Train teams and embed new KPIs

While the initial investment of effort will be largely one-off in the year of transition, you will still require ongoing systems and controls maintenance to ensure that contract data is accurate and complete.

Step 6: Disclosure preparation

  • Prepare expanded lease and revenue disclosures and judgement notes
  • Draft illustrative templates for audit committees and ensure consistency across group entities

Communication is key

To help this process run as smoothly as possible:

  • Share impacts internally across finance and operations and externally with auditors, lenders and investors to avoid surprises
  • Engage early with auditors to confirm interpretations and avoid last-minute adjustments
