FRS 102 Changes in 2026: Leases, Lenders and Why Timing Matters

The biggest changes to UK GAAP in years now apply to accounting periods beginning on or after 1 January 2026. For December year ends, the first set of accounts under the new rules is being built right now.

Our earlier article on the latest amendments to UK GAAP covered the technical detail of the revenue changes. This piece is the practical view of what the FRS 102 changes mean for your business. We asked our founder, Asli Saka, what finance directors should actually be doing about it.

What has changed in FRS 102 from 1 January 2026?

Two changes will be felt by most businesses:

•      Leases. The split between operating and finance leases goes. Most leases now sit on the balance sheet as a right-of-use asset and a lease liability. Short-term leases of 12 months or less and leases of low-value assets can stay off.

•      Revenue. A five-step model now decides when, and how much, revenue is recognised: identify the contract, identify the performance obligations, set the transaction price, allocate it, and recognise revenue as each obligation is satisfied.

For leases, the cumulative effect of the change is taken to equity at the start of the first year, and comparatives are not restated. For revenue, businesses can choose between full retrospective application and a modified approach. Micro-entities reporting under FRS 105 are not affected by the lease changes.

Who is affected by the FRS 102 changes?

“The businesses that need to pay attention are those with significant lease commitments or complex customer contracts. In practice, that's a lot more companies than people initially realise. We're talking about retailers, hospitality businesses, manufacturers, logistics companies, technology firms with subscription models, professional service firms working on long-term contracts, and groups with external lenders or investors.”

“If you're a finance director who signs off management accounts, speaks to lenders, reports to shareholders, or relies on financial KPIs to make decisions, this isn't just an accounting update. It has the potential to change how your business looks on paper and how others assess its performance.”

FRS 102 lease accounting: the cash doesn't change, the ratios do

“The simplest way to think about it is this: leases are no longer just a monthly expense running through the profit and loss account. If you've got property leases, vehicle fleets, warehouse space or equipment leases, you'll effectively be recognising the future commitment upfront. For many businesses, the cash doesn't change at all. You're still paying the same rent every month. What changes is how that commitment is presented in the accounts.”

“A scenario I can easily see is a business that has always comfortably met its leverage covenants. Then they apply the new lease accounting rules and suddenly several million pounds of lease liabilities appear on the balance sheet. Nothing has changed commercially. The business hasn't borrowed more money. Cash generation hasn't deteriorated. But the ratios the bank monitors have changed overnight.”

The practical step: check how your facility agreement defines debt and earnings, and whether it refers to the accounting rules in force when it was signed. If the answer isn't clear, talk to your lender well before year end.

FRS 102 revenue recognition: what exactly have you promised?

“Businesses with straightforward sales transactions may see very little impact. The biggest challenges tend to arise where contracts contain multiple promises, long delivery periods, milestone payments, retainers, subscriptions, licences, implementation services or performance-based fees.”

“Technology businesses are a good example. A contract might include software licences, implementation support, training and ongoing maintenance. Finance teams need to identify each element and determine when revenue should actually be recognised. The difficulty isn't recording the invoice. It's determining exactly what has been promised, when that promise has been fulfilled, and how the revenue should be allocated across the contract.”

The hidden workload

“The hidden workload is almost always data gathering. People focus on the accounting treatment because that's the technical part. In reality, most of the effort sits in finding contracts, reviewing lease agreements, identifying missing information, understanding historic transactions and validating assumptions. The accounting entries often take less time than the preparation work needed to support them.”

The most common mistake

“Leaving it too late. Many finance teams assume they'll deal with it during year-end preparation. By that point, the challenge becomes far more difficult because you're working under reporting deadlines. The mistake isn't misunderstanding the standard. It's underestimating the time needed to prepare properly.”

Where to start with FRS 102 implementation

“I'd tell them not to start with the accounting manual. Start by identifying where the changes could affect your business. Once you know where the exposure is, you can assess the financial impact and prioritise the areas that require attention.”

In practice, that means five steps:

1.    List every lease, with its start date, term, payments and any break clauses.

2.    Pull your largest customer contracts and note what each one promises the customer.

3.    Check your covenant definitions and the KPIs used for bonuses and board reporting.

4.    Model the likely effect on profit, net assets and gearing.

5.    Talk to your lender and your auditor before year end, not after.

When accounting becomes commercial

“One thing that often surprises finance directors is how quickly a purely accounting change can become a commercial issue. Management initially view a reporting change as something only the finance team needs to worry about. Then, once the numbers are modeled, it becomes clear the changes could affect banking discussions, shareholder reporting, bonus calculations and performance metrics. That's usually the moment when the conversation shifts from compliance to business impact.”

How we help

“We start by understanding the business rather than jumping straight into the technical accounting. Our first step is usually an impact assessment. We identify where the changes apply, quantify the likely effect on the financial statements and highlight any wider implications for lenders, shareholders, management reporting or business decisions. From there, we help build a practical implementation plan. The aim isn't simply to achieve compliance. It's to give management clarity and confidence so there are no surprises.”

Questions we're asked about FRS 102

What is changing in FRS 102 from 1 January 2026?

Two changes affect most businesses. Most leases now sit on the balance sheet as a right-of-use asset and a lease liability, and a five-step model now decides when, and how much, revenue is recognised. Both apply to accounting periods beginning on or after 1 January 2026.

Will the new FRS 102 lease rules affect my loan covenants?

They can. The cash you pay does not change, but lease liabilities appear on the balance sheet, which can move the ratios your bank monitors. Check how your facility agreement defines debt and earnings, and talk to your lender well before year end.

Do the FRS 102 lease changes apply to micro-entities?

No. Micro-entities reporting under FRS 105 are not affected by the lease changes.

When should I start preparing for the FRS 102 changes?

Now. For December year ends, the first set of accounts under the new rules is being built right now. Leaving it until year-end preparation means working under reporting deadlines.
