Major Changes to UK GAAP in 2026

From 1 January 2026, significant changes to UK GAAP (Generally Accepted Accounting Practice) will come into force, with a particular focus on revenue recognition and lease accounting. These updates align Sections 23 and 20 more closely with international standards – IFRS 15 and IFRS 16 –and will require proactive planning from finance teams.

If your business prepares financial statements under UK GAAP, now is the time to start preparing.

What’s Changing to uk gaap?

Revenue Recognition (Section 23)

The revised Section 23 introduces a five-step model for revenue recognition, designed to bring greater consistency and transparency.

Businesses most likely to be affected include:

• Construction and long-term contract providers
• Service-based businesses
• Companies offering bundled contracts

These changes will likely affect how and when revenue is recognised—potentially impacting earnings, key metrics, and even your tax position.

Lease Accounting (Section 20)

Under the new rules, all leases must be recognised on the balance sheet, reflecting the full financial commitment of the business.

This means:

• Greater transparency around liabilities
• Potential implications for financial covenants
• A more complex accounting process requiring detailed lease data

While the UK approach may include some practical exemptions to ease the transition, this still represents a significant shift for many.

Enhanced Disclosure Requirements

Smaller companies will also be expected to meet stricter disclosure rules to provide a more complete, true and fair view of their financial position.

Why It Matters

These changes are far-reaching. They could impact:

• Earnings and dividend planning
• Earnouts in business sales
• Financial covenants with lenders
• Stakeholder confidence and investment decisions

As a result, leaving implementation too late could result in delays to your year-end accounts, increased audit fees, or covenant breaches.

What Should You Do Now?

While 2026 may seem a way off, early action is essential. Here’s a three-step plan to get started:

1. Assess the Impact

Start by understanding how these changes will affect your business:

• Review your revenue contracts and lease agreements
• Identify complexities in bespoke contracts
• Seek guidance from your local TC Group office

2. Engage Stakeholders

Speak with your investors and lenders about the potential impact on:

• Earnings forecasts
• Financial ratios
• Existing covenants or credit agreements

Being proactive will help maintain trust and avoid surprises.

3. Develop an Implementation Plan

Think about:

• Gathering and standardising contract and lease data
• Training your finance team
• Determining what additional systems or processes may be required
• Ensuring your team has the skills and resources to adopt the changes

Remember: your auditors cannot do the heavy lifting due to independence restrictions.
