FRS 102 revenue recognition changes from January 2026: aligning UK GAAP with IFRS 15

The Financial Reporting Council’s amendments to FRS 102 represent one of the most significant changes to UK GAAP in recent years. For accounting periods beginning on or after 1 January 2026, the revised Section 23 Revenue guidance under FRS 102 applies a framework broadly aligned to the principles of IFRS 15 Revenue from Contracts with Customers. 

The updated framework introduces a structured five-step revenue recognition model that moves away from the traditional “risks and rewards” approach towards recognising revenue based on the transfer of control to the customer. For many businesses reporting under UK GAAP, this may affect the timing of revenue recognition, accounting disclosures and wider commercial metrics. 

The revised Section 23 requirements form part of wider amendments to FRS 102, including the FRS 102 upcoming changes to lease accounting already affecting many UK GAAP entities. 

What is changing under FRS 102 Section 23? 

The revised Section 23 introduces a comprehensive framework for recognising revenue from contracts with customers. The amendments bring UK GAAP closer to international accounting standards while improving consistency and comparability across financial reporting. 

Under the previous FRS 102 guidance, revenue recognition often depended on when significant risks and rewards transferred to the customer. Under the amended framework, the focus instead shifts to when control of goods or services transfers to the customer. 

This updated approach may accelerate or delay revenue recognition depending on the nature of contractual arrangements and performance obligations. As a result, businesses may need to reassess existing accounting policies, customer agreements and reporting procedures. 

The five-step revenue recognition model 

The revised Section 23 adopts a five-step model broadly aligned with IFRS 15. Businesses must assess contracts using the following framework. 

Step 1: Identify the contract with the customer 

Businesses must determine whether an enforceable contract exists and whether both parties have approved the arrangement. The contract must have commercial substance and clearly identifiable payment terms. 

Step 2: Identify the performance obligations 

Entities must identify the distinct goods or services promised within the contract. In some cases, contracts may contain multiple performance obligations that require separate accounting treatment. 

This may be particularly relevant for software businesses, professional service firms, subscription-based businesses and companies providing bundled services or support agreements. 

A software business providing implementation services, licensing and ongoing support may now need to separate those elements into distinct performance obligations under the revised Section 23 model. 

Step 3: Determine the transaction price 

The transaction price represents the amount the business expects to receive in exchange for transferring goods or services to the customer. 

This may include variable consideration such as discounts, rebates, bonuses, performance incentives or penalties. 

Step 4: Allocate the transaction price 

Where contracts contain multiple performance obligations, the transaction price must be allocated between them based on their relative standalone selling prices. 

This may require additional judgement and supporting documentation where standalone pricing is not directly observable. 

Step 5: Recognise revenue when or as obligations are satisfied 

Businesses recognise revenue either at a point in time or over time, depending on when control transfers to the customer. 

For some entities, this may significantly change the profile of reported revenue and profitability across accounting periods. 

Who is most affected by the FRS 102 revenue recognition changes? 

Although the revised framework applies broadly across UK GAAP entities, some sectors are expected to experience more significant changes than others. 

These may include: 

– software and technology businesses 
– construction and property businesses 
– engineering and manufacturing companies 
– professional service firms 
– businesses with subscription-based income models 
– businesses offering warranties, maintenance or support packages 
– businesses with milestone or performance-based contracts 

Businesses with complex contractual arrangements may find that revenue previously recognised at a single point in time now requires recognition over the life of a contract, or vice versa. 

Why do the FRS 102 revenue recognition changes matter? 

The revised framework is not simply an accounting exercise. The changes may create wider operational, commercial and reporting implications across a business. 

Potential impacts may include: 

– changes to reported profitability and financial performance 
– impacts on distributable reserves 
– covenant compliance considerations 
– revisions to management reporting and KPIs 
– changes to contract drafting and pricing structures 
– additional accounting judgements and disclosures 
– accounting system and process changes 

Businesses may also need to review how they negotiate future contracts, as relatively small contractual differences could materially affect revenue recognition outcomes under the revised model. 

Entities should also consider transitional adjustments, comparative reporting implications and whether existing contracts require reassessment under the amended framework. 

What should businesses do now? 

Although the revised requirements now apply for accounting periods beginning on or after 1 January 2026, many businesses are still assessing the practical impact of the changes. 

Early preparation may include reviewing customer agreements, identifying performance obligations, assessing accounting systems and evaluating whether additional disclosures or accounting judgements are required. 

Finance teams may also require training to understand how the revised framework applies in practice, particularly where contracts involve variable consideration, bundled services or long-term customer arrangements. 

For some entities, transitional adjustments could materially affect opening reserves and comparative reporting. 

Further technical guidance is available from the Financial Reporting Council and ICAEW implementation guidance.
