For UK companies preparing and filing accounts, four major changes are taking effect between now and 2028. This is a summary of what’s changing and how we can help you to be ready. 

  • Affecting all UK companies
  • For periods beginning on or after 6 April 2025

  • Significant amendments to UK GAAP, particularly lease accounting (FRS 102 only) and revenue recognition
  • Already in effect, as it applies for periods beginning on or after 1 January 2026
    This means that a company with a December 2026 year end is already in the first affected year, with transition balances captured from 1 January 2026
  • Most leases move onto the balance sheet (a right-of-use asset and a lease liability, replacing off-balance-sheet operating leases)
  • Revenue follows a five-step model – from identifying contracts to establishing price and revenue recognition
  • For businesses with long leases, the balance-sheet impact can be material – increasing reported debt and borrowing levels, changing key profit measures, and affecting bank covenants, KPIs and size thresholds
  • The revenue change is less visible but higher risk, sitting in the detail of customer contracts

Action to take now:

An impact assessment on leases and revenue, and early conversations with lenders

  • Revenue and gross asset size thresholds increased for accounting periods beginning on or after 6 April 2025; employee thresholds haven’t changed
  • Entities must meet at least two of the three size criteria for two consecutive years
  • As a result, your company/group may move into a lower size category, and some entities that were previously subject to a statutory audit may no longer meet the audit requirement
  • For accounting periods beginning on or after 6 April 2025, the new thresholds will first apply to companies with a 31 March year end in the year ending 31 March 2027. If your year end falls close to the cut-off date or your results are near a size threshold, take advice early, as the timing can affect how and when the new limits apply
  • Recognising lease assets and liabilities on the balance sheet increases gross assets for company size assessment purposes. Your company may move up a size threshold despite the increase in threshold boundaries

  • For IFRS reporters, IFRS 18 applies to periods beginning on or after 1 January 2027, replacing IAS 1. Retrospective application is required
  • It changes presentation, not profit: new income and expense categories, required subtotals, and disclosure of management-defined measures such as adjusted EBITDA, with comparatives restated
  • Net profit is unchanged, but review covenants, KPIs and remuneration that reference reported metrics
  • Businesses preparing financial statements under FRS 101 will also need to assess the impact of IFRS 18, although certain new disclosure requirements don’t apply to qualifying FRS 101 entities

  • From April 2028, UK accounts filing will move to software-only (electronic) submission, and companies will not be able to file abridged accounts
  • These changes form part of the Economic Crime and Corporate Transparency Act 2023 (ECCTA), which is intended to improve the quality, transparency and reliability of information held at Companies House and help tackle economic crime
  • The previously announced plan requiring all companies – including small and micro-entities – to file a full profit and loss account on the public register has been relaxed
  • The key step is to ensure your accounts are produced through commercial software

Our accounts and audit specialists can run a focused impact assessment across all these four areas: evaluating the effect on your balance sheet, covenants, KPIs and reporting, and giving you confidence that your business is fully prepared for the changes.

We can also provide a detailed guidance that includes worked examples and real client scenarios.

What are the most important accounting and accounts filing changes UK companies should be preparing for? 

The key changes are the revised FRS 102 requirements for leases and revenue recognition, higher company size thresholds, the introduction of IFRS 18, and mandatory software-only accounts filing at Companies House. Together, these changes can affect financial reporting, audit requirements, banking arrangements, KPI reporting, and compliance processes. Businesses should assess which changes apply to them and start planning well before their reporting periods are affected.

How do I know whether my business is affected by FRS 102 changes? 

Any business preparing accounts under FRS 102 should assess the impact of the updated standard. The most significant effects are typically seen where a company has property leases, equipment leases, vehicle fleets, or complex customer contracts. Even where reported profits do not change significantly, the accounting treatment may alter how assets, liabilities, revenue, and performance measures appear in the financial statements.

Why are lease accounting changes important for lenders and bank covenants? 

Bringing most leases onto the balance sheet can increase reported liabilities and change key financial ratios. As a result, existing banking covenants, borrowing limits and internal KPIs may produce different results even where the underlying business has not changed. Businesses with significant leased property or equipment should discuss potential impacts with lenders early to avoid unexpected covenant issues.

Does the new FRS 102 lease accounting rule mean my business has taken on more debt? 

Not necessarily. The change is primarily an accounting change rather than a change in commercial reality. Businesses have always had contractual lease commitments, but many operating leases were previously reported off the balance sheet. The revised rules bring these obligations into the financial statements as lease liabilities, making them more visible to investors, lenders, and other stakeholders.

What is changing with revenue recognition under FRS 102? 

Revenue recognition is moving to a more structured five-step model that focuses on contracts, performance obligations, pricing and the timing of delivery. For straightforward transactions, the impact may be limited. However, businesses with long-term contracts, multiple service components, subscription arrangements, or bespoke customer agreements may need to review how and when revenue is recognised. Contract reviews can help identify areas where accounting treatment may change.

Could the new company size thresholds remove my audit requirement? 

Potentially, yes. Some companies that previously exceeded the thresholds for a statutory audit may fall into a lower size category under the revised limits. However, eligibility depends on meeting at least two of the relevant criteria for the required period, and the rules can be complex. Businesses close to the thresholds should seek advice, particularly if growth, restructuring, or accounting changes may affect their classification.

Can a company move into a different size category because of the lease accounting changes? 

Yes. This is a commonly overlooked consequence of the FRS 102 amendments. Recognising lease assets on the balance sheet can increase gross assets, which may affect company size calculations. In some cases, a business could move into a larger reporting category despite the increase in the statutory size thresholds. The interaction between these two changes should be reviewed carefully.

What is IFRS 18 and who needs to comply with it? 

  IFRS 18 is a new financial reporting standard that replaces IAS 1 for affected businesses from accounting periods beginning on or after 1 January 2027. It applies mainly to organisations reporting under IFRS and has implications for entities using FRS 101. The standard introduces new presentation requirements, categories of income and expenses, and additional disclosures aimed at improving consistency and transparency in financial statements.

Will IFRS 18 change my company’s profit figures? 

No. IFRS 18 changes how financial performance is presented rather than how profit is calculated. Net profit remains the same, but businesses may need to report different subtotals and explain management-defined performance measures such as adjusted EBITDA. Companies should review reporting frameworks, management reporting packs, remuneration arrangements, and lending agreements that rely on specific performance metrics.

What happens when Companies House moves to software-only filing in 2028? 

From April 2028, companies will need to submit accounts electronically through approved software rather than using existing filing methods. The changes arise from the Economic Crime and Corporate Transparency Act 2023 and are designed to improve the quality and reliability of information held by Companies House. Businesses that still rely on manual processes or unsupported systems should begin considering how their accounts production and filing processes will operate in a fully digital environment.

Do small companies and micro-entities need to prepare for the Companies House changes? 

Yes. Although some previously proposed disclosure requirements have been relaxed, the move to electronic filing affects companies of all sizes. Small companies and micro-entities should ensure that their accounts preparation process is compatible with commercial software and that internal teams understand future filing requirements. Leaving preparations until 2028 could create unnecessary compliance pressures.

When should businesses start preparing for these accounting and reporting changes? 

The best time is as early as possible. Some changes are already effective, while others require retrospective information, contract reviews, covenant assessments, or system updates. Early preparation provides time to evaluate impacts on financial statements, tax planning, reporting obligations, audit requirements, banking relationships, and business decision-making. A structured impact assessment can help identify priorities and avoid last-minute surprises.
