The UK GAAP shake-up: turning insight into action

As major reforms to FRS 102 are set to reshape balance sheets and borrowing capacity, Andrew Watkinson, Managing Director at CPiO, one of the UK’s longest-standing Sage partners, breaks down what finance leaders need to know and how they can turn insight into action.

From January 2026, UK accounting is set for one of its most significant changes in recent memory. The updates to lease accounting under UK GAAP, FRS 102, will not just tweak how leases are reported; they will fundamentally reshape how businesses present their financial position to lenders, investors and auditors.

This change is far from technical housekeeping. It has the potential to impact loan covenants, audit thresholds and EBITDA reporting.

Finance leaders need to treat this as a strategic event, not a compliance footnote.

From simplicity to substance

Historically, many organisations have enjoyed the simplicity of recording operating leases as rental expenses, a consistent line item that never appeared on the balance sheet. That model is now being retired. Inspired by IFRS 16, the revised FRS 102 removes the distinction between finance and operating leases for lessees.

From 2026, nearly all leases will need to be reported on the balance sheet. That means recognising two key elements:

  • A Right of Use Asset: representing the lessee’s right to use the leased asset.
  • A Lease Liability: representing the present value of the obligation to make lease payments.

For businesses with extensive leasing arrangements, this will create a dramatic increase in both reported assets and liabilities.

Why it matters for financial strategy

The implications go far beyond accounting policy. This change will affect how lenders assess creditworthiness, how boards view leverage and how businesses qualify for audit exemptions or reporting simplifications.

  • Balance Sheet Expansion: Both assets and liabilities will increase. Key ratios, such as debt to equity or gearing, may deteriorate on paper,  even if nothing changes operationally.
  • EBITDA Inflation: As lease costs move below the line, split between depreciation and interest, EBITDA may appear stronger. While this could superficially improve performance metrics, it may also trigger unintended consequences in loan agreements.
  • Audit and Reporting Thresholds: The larger balance sheet could push some companies into audit territory or disqualify them from streamlined reporting frameworks.
  • Hidden Lease Risk: Leases embedded within broader service contracts need to be identified. Missing them risks misstatement and potential audit issues.

High-risk sectors

All industries will feel some impact, but those heavily reliant on leased infrastructure face the greatest disruption. This includes retailers with multiple property leases, logistics firms running leased fleets and manufacturers with equipment leasing arrangements.

For these businesses, the shift could alter not just accounting treatment, but how external stakeholders view risk and stability.

Time to act

With the 2026 implementation date approaching fast, now is the time to take decisive steps. Begin by conducting a comprehensive review of all lease agreements across the business, including those that might be embedded in broader service contracts.

Capturing the full picture, lease term, payment profile, renewal options and related expenses is essential for accurate reporting under the new standards.

Once leases are identified, scenario modelling will be key. Finance teams should project how the new rules will influence balance sheets and income statements, particularly in relation to EBITDA and key financial ratios like debt-to-equity or interest cover. This modelling will be critical for assessing the risk of breaching existing loan covenants.

Where those risks exist, open discussions with lenders now to explain the anticipated changes and agree how covenants will be measured going forward.

Technology and expertise will also play a major role in managing the transition. Finance systems must be capable of supporting the right calculations, disclosures and reporting formats.

For businesses with large or complex lease portfolios, dedicated lease accounting software may be required. It’s also vital to consult auditors early to validate assumptions and ensure alignment. Proactive planning and clear communication will reduce compliance risk and ensure this transition becomes a lever for better financial visibility, not a burden.

Turning compliance into competitive advantage

This isn’t simply a change in standards; it’s a change in how financial health is interpreted. The updated FRS 102 lease rules bring greater transparency, but they also demand stronger leadership from finance professionals.

Handled well, the transition can enhance internal reporting, sharpen financial planning and demonstrate governance maturity to external stakeholders. Delay and the business risks, scrambling to meet compliance, straining lender relationships, or making missteps that could have been avoided with foresight.

The numbers may change, but the strategy is yours to shape. Now is the time to lead.
