UK businesses applying FRS 102 are now working under some of the most significant accounting changes the standard has seen in years.
Most amendments from the Financial Reporting Council’s Periodic Review 2024 apply to accounting periods beginning on or after January 1, 2026. The biggest changes affect leases and revenue recognition, with additional updates covering fair value measurement, tax treatment, and disclosures.
Understand the Revised FRS 102 Requirements
The first step is determining which amendments affect the business.
The latest changes to FRS 102 move several areas of UK GAAP closer to international accounting principles while retaining some simplified requirements for FRS 102 preparers.
The impact will vary considerably. A company with few leases and straightforward sales may see limited disruption, while a business with multiple properties, vehicles, equipment agreements, or complex customer contracts may need more substantial changes.
Rather than reviewing every accounting policy equally, finance teams should focus first on areas where the underlying transactions are affected.
More Leases Are Moving Onto the Balance Sheet
One of the biggest changes affects lessee accounting.
The previous distinction between operating and finance leases has been removed for most lessees. Many agreements that previously resulted primarily in rental expense will now create a right-of-use asset and lease liability.
Qualifying short-term leases and leases of low-value assets can still receive exemption treatment.
Businesses should identify property, vehicle, machinery, and equipment agreements that may fall within the revised rules. Contracts do not have to be labeled as leases to require analysis.
The accounting change can also affect EBITDA, gearing, current ratios, and interest coverage even when the underlying cash payments remain unchanged.
Companies with borrowing arrangements should therefore check whether loan covenants rely on metrics affected by the new treatment.
Revenue Recognition Has Also Changed
Section 23 of FRS 102 now uses a five-step model for revenue from contracts with customers.
Businesses need to identify the contract, determine the promises made to the customer, establish the transaction price, allocate that price where necessary, and recognize revenue as the promised goods or services are transferred.
For simple retail transactions, the outcome may remain largely unchanged.
More complicated arrangements deserve closer attention. Long-term service contracts, bundled products and services, variable consideration, customer incentives, and contracts containing several deliverables may produce different timing or measurement outcomes.
The Financial Reporting Council’s FRS 102 guidance provides the current standard and supporting material for businesses applying UK GAAP.
Fair Value Measurement Has Been Updated
The Periodic Review also introduced a new Section 2A covering fair value measurement.
The definition and measurement approach are now more closely aligned with IFRS 13. Liability fair values, for example, are based on transfer value rather than settlement value, and non-performance risk can affect measurement.
Businesses holding financial instruments, investment properties, or other items measured at fair value should check whether existing valuation methods still comply.
The result may not always change, but the method used to reach it may need to.
Pay Attention to Transition Rules
The transition method depends on the accounting topic.
For the revised lease requirements, businesses generally use a modified retrospective approach. The cumulative effect is recognized when the amendments are first applied, while comparative information is generally not restated under that method.
Revenue offers more than one transition approach, including fully retrospective and modified retrospective options.
Those differences matter when comparing current results with previous periods. Financial statements may show movements caused partly by the accounting transition rather than underlying business performance.
Clear disclosure can help users understand that distinction.
Strengthen Contract and Data Controls
The new rules place more pressure on the quality of contract information.
Lease details may sit with facilities, procurement, or branch managers, while customer terms may be held in sales systems. Finance needs access to the information that affects accounting without reconstructing it at year-end.
Useful controls include:
- Central registers for significant contracts
- Defined approval procedures
- Finance review of unusual agreements
- Reconciliation between operational and accounting records
- Clear ownership of contract changes
The objective is to capture relevant information when transactions happen rather than searching for it months later.
Consider How Facility Investments Are Recorded
Operational spending can also create accounting questions that need attention before projects are completed.
Manufacturing, warehousing, and industrial businesses may invest in ventilation, extraction equipment, dust control, or an industrial air purifier to improve working conditions.
Those projects can raise questions around capitalization, useful life, depreciation, leasing arrangements, and whether building work and equipment should be recorded separately.
Finance should understand who owns the equipment, what installation costs were incurred, and whether the arrangement involves purchase, lease, or service elements.
That information is much easier to capture during procurement than after the project has been completed.
Check Systems Before Reporting Pressure Builds
More complex lease and revenue calculations can expose limitations in spreadsheets or older accounting systems.
Businesses with a small number of straightforward transactions may still manage effectively with existing tools. Larger organizations may need more structured systems for contract data, lease calculations, disclosures, or recurring reporting.
The key question is whether the process can produce consistent, reviewable results without excessive manual intervention.
If reconciliations, journal entries, or disclosure schedules require repeated manual correction, the system may no longer be suitable for the volume or complexity involved.
Explain Changes to Financial Statement Users
The 2026 amendments can change reported figures even when the economics of the business remain broadly the same.
A company may report higher assets and liabilities because of lease accounting. EBITDA may change because lease costs are presented differently. Revenue timing may shift under the new five-step model.
Directors, lenders, investors, and other users should understand whether a significant movement comes from business performance or a change in accounting treatment.
That is especially important where financial ratios influence lending decisions, bonuses, or internal performance targets.
Focus on the Changes That Matter Most
Businesses do not need to rebuild every accounting process simply because FRS 102 has changed.
The priority is identifying transactions affected by the amendments, applying the correct transition method, and making sure contract data and reporting systems can support the new requirements.
For many companies, leases and revenue will require the most attention. Others may also need to revisit fair value measurement, disclosures, tax treatment, or facility-related investments.
The strongest approach is targeted rather than repetitive: identify the affected areas, fix the underlying process, and make sure the resulting financial statements clearly explain what changed.
