IFRS 15 Revenue Flowchart — UK Edition

IFRS 15 in United Kingdom

IFRS 15 Adoption in the United Kingdom

The United Kingdom adopted IFRS 15 Revenue from Contracts with Customers as part of UK-adopted international accounting standards, effective for annual periods beginning on or after 1 January 2018. Following the UK's departure from the European Union, the UK Endorsement Board (UKEB) assumed responsibility for endorsing IFRS standards for use in the UK. UK-adopted IFRS 15 is substantively identical to the IASB-issued version, with no carve-outs or modifications to the five-step revenue recognition model. All listed companies and AIM-traded entities preparing consolidated financial statements must apply UK-adopted IFRS 15, while private companies may choose between IFRS and FRS 102 (the Financial Reporting Standard applicable in the UK and Republic of Ireland).

FRC Regulatory Expectations and Enforcement Focus

The Financial Reporting Council has made revenue recognition a sustained area of supervisory focus since IFRS 15 became effective. The FRC's Corporate Reporting Review (CRR) team has written to numerous companies challenging the adequacy of their IFRS 15 disclosures, particularly regarding the identification of performance obligations in bundled arrangements, the allocation of the transaction price to distinct goods and services, and the timing of revenue recognition for over-time versus point-in-time transfers. The FRC published a Thematic Review on IFRS 15 implementation in 2019, which assessed the quality of first-time adoption disclosures across a sample of UK-listed entities and identified widespread deficiencies in the granularity and entity-specificity of revenue accounting policy descriptions.

FRC Thematic Review Key Findings

• Many entities provided generic descriptions of their revenue recognition policies that did not explain how the five-step model was applied to their specific contracts and business activities.
• Disclosure of significant judgements, particularly around the identification of performance obligations and the determination of the transaction price for variable consideration, was often insufficient.
• The disaggregation of revenue required by IFRS 15.114-115 did not always provide meaningful insight into the nature, amount, timing, and uncertainty of revenue streams.
• Transition disclosures lacked quantified reconciliation between IAS 18 and IFRS 15 balances, making it difficult for users to assess the standard's impact.

FRC Audit Quality Review Inspection Findings

The FRC's Audit Quality Review (AQR) team has consistently identified revenue recognition as a significant risk area in its annual inspection cycle. Common findings include insufficient auditor challenge of management's identification of distinct performance obligations in multi-element arrangements, inadequate testing of variable consideration estimates including rebates and volume discounts, limited assessment of contract modification accounting, and failure to evaluate the appropriateness of the input or output methods used to measure progress for over-time revenue recognition. The AQR has emphasised that auditors must go beyond testing controls and perform substantive procedures that directly address the IFRS 15 five-step model application.

UK GAAP Alternative: FRS 102 Section 23

Private companies in the UK that do not choose to apply IFRS may report under FRS 102, where revenue recognition is governed by Section 23 Revenue. FRS 102 Section 23 is simpler than IFRS 15, based on the former IAS 18 principles, and uses a risks-and-rewards transfer model rather than the IFRS 15 control-transfer approach. For groups with both listed and private entities, the parent company applies IFRS 15 in consolidated financial statements while subsidiaries may use FRS 102 in their individual entity accounts, creating the need for consolidation adjustments where the two frameworks produce different revenue timing outcomes.

Companies Act Requirements

UK companies must also comply with Companies Act 2006 requirements that affect revenue presentation and disclosure. The strategic report must provide a fair review of the entity's business, including key performance indicators that often reference revenue metrics. The Companies (Miscellaneous Reporting) Regulations 2018 added Section 172 reporting requirements, which may reference revenue-related stakeholder considerations. Directors must ensure that revenue recognition policies are consistent with the true and fair view requirement and are adequately explained in the notes to the financial statements.

Industry-Specific Considerations for the UK Economy

The UK economy has significant concentrations in financial services, technology, construction, defence contracting, and professional services, each presenting distinct IFRS 15 challenges. For UK construction companies, the timing of revenue recognition under the over-time model and the estimation of variable consideration in target-cost contracts require careful application of IFRS 15 paragraphs 35-37 and 50-59. Technology and software companies face complexity in identifying distinct performance obligations within bundled SaaS arrangements and determining whether software licences provide a right to access or a right to use. Defence contractors dealing with the Ministry of Defence must assess whether long-term contracts contain single or multiple performance obligations and how to account for contract modifications through change orders.

Regulatory Inspection Focus Areas

FRC AQR findings include insufficient challenge of performance obligation identification in multi-element arrangements, inadequate testing of variable consideration estimates and constraint assessments, limited scrutiny of over-time revenue recognition input methods, and failure to assess contract modification accounting for long-term contracts. The FRC Thematic Review identified widespread deficiencies in the entity-specificity and granularity of IFRS 15 policy disclosures among UK-listed entities.
