UK GAAP 2026: A practical guide to the financial reporting changes

How businesses can prepare for the most significant overhaul of UK GAAP since 2013

From 1 January 2026, wide‑ranging changes to UK Generally Accepted Accounting Practice (GAAP) came into force, representing the most significant reform to financial reporting since the introduction of FRS 102 in 2013.

Driven by the Financial Reporting Council’s (FRC) 2024 periodic review, the amendments bring UK GAAP into closer alignment with International Financial Reporting Standards (IFRS). As a result, many businesses will need to reconsider how they recognise revenue, account for leases, and present financial performance.

These changes go beyond accounting compliance alone. They may affect reported profits, tax timing, financial systems, banking covenants, and commercial arrangements, making early assessment and preparation essential.

In our latest guide, we bring together the key changes and their practical implications in one clear, accessible resource.
