Lease Accounting Under FRS 102 (2026 Changes): A Practical Guide

If your organisation leases premises, vehicles, equipment or anything else of substance, the way those leases show up in your accounts is about to look very different. For periods beginning on or after 1 January 2026, FRS 102 moves lessees onto an on-balance-sheet model that looks a lot like IFRS 16 — and for many UK and Irish businesses, this is the single biggest change to hit their financial statements in years. This guide walks through what's changing, where FRS 102 has deliberately kept things simpler than its IFRS cousin, how the transition actually works, and what it means for your numbers, your covenants and your reporting timetable.

What's Changing: From Rental Charges to Right-of-Use Assets

Under the old FRS 102 rules, most leases were classified as either "finance leases" (which went on the balance sheet) or "operating leases" (which didn't). An operating lease — your typical office rental, car lease or equipment hire — simply generated a rental expense in the profit and loss account, spread evenly over the lease term. The obligation to keep paying rent for the next five, ten or fifteen years never appeared as a liability. It was, in effect, off-balance-sheet financing, hiding in the notes.

The Financial Reporting Council's Periodic Review 2024 amendments scrap that distinction for lessees. Almost every lease — subject to the exemptions below — now results in two new entries: a right-of-use (ROU) asset, representing the right to use the underlying item for the lease term, and a corresponding lease liability, representing the obligation to make future lease payments. This single-model approach mirrors IFRS 16, which large UK-listed and many international groups have been applying since 2019. If your organisation sits in a group that already reports under IFRS, this will feel familiar. If you've only ever reported under old UK GAAP, it's a genuinely new way of thinking about leases.

Where FRS 102 Deliberately Stays Simpler Than IFRS 16

It's worth being clear that FRS 102 is not simply "IFRS 16 with a new cover page." The FRC built in several simplifications specifically to keep the standard proportionate for the smaller, less resourced entities that report under FRS 102, and it's worth knowing about them before you assume the worst.

First, there's a short-term lease exemption: leases with a term of 12 months or less at the commencement date can be kept off the balance sheet entirely and expensed on a straight-line basis, just as before, provided the lease doesn't contain a purchase option.

Second, there's a low-value asset election. Leases of assets that are low in value when new can also be exempted, at the lessee's choice, on a lease-by-lease basis. FRS 102 doesn't set a specific monetary threshold for this — so resist the temptation to look for a magic number. What it does give is guidance by example: assets such as cars, cranes, tractors, aircraft and buildings are explicitly not considered low-value, no matter how old or heavily depreciated they might be, because their value when new is significant. By contrast, items like laptops, tablets and small items of office furniture are the kind of thing the exemption is aimed at. Judgement is required, and that judgement should be applied consistently and documented.

Third — and this is a genuinely useful practical simplification — FRS 102 offers a simplified "obtainable borrowing rate" (OBR) as an alternative to the lessee's incremental borrowing rate when discounting lease payments. Rather than working through IFRS 16's full discount-rate hierarchy (which asks preparers to first try to determine the rate implicit in the lease, and only fall back to an incremental borrowing rate when that can't reasonably be determined), FRS 102 allows entities to use the rate they would obtain if borrowing over a similar term with similar security. The FRC has been explicit that this is intended to be simpler to determine in practice than the IFRS 16 approach — useful news for finance teams without a treasury function to lean on.

Transition: Modified Retrospective, No Restated Comparatives

The mandatory transition method is modified retrospective. In practice, this means you don't need to go back and restate your prior-year comparative figures as though the new rules had always applied. Instead, you recognise the cumulative effect of applying the new lease accounting as a one-off adjustment to opening retained earnings at the start of the period of initial application. It's a considerably lighter lift than a full retrospective restatement, but it still requires a proper lease-by-lease calculation at the transition date.

To make that calculation more manageable, several practical expedients are available on transition:

• Group entities that are already IFRS 16 compliant can carry across their existing IFRS 16 right-of-use asset and lease liability amounts rather than recalculating from scratch.
• A single discount rate can be applied to a portfolio of leases with reasonably similar characteristics, instead of calculating a separate rate lease by lease.
• Hindsight can be used when assessing lease term — for example, in deciding whether an extension or termination option is reasonably certain to be exercised.
• Entities can rely on their previous assessment of whether an operating lease was onerous under old UK GAAP, rather than carrying out a fresh impairment test on the new right-of-use asset at transition.
• There's no need to reassess whether contracts entered into before the transition date actually contain a lease — existing conclusions can stand.

Taken together, these expedients are designed to stop transition turning into a research project on every single contract you hold. Use them — but document which ones you've applied, since your auditors and your accounts' disclosures will need to reflect that.

What This Actually Does to Your Numbers

This is the part that tends to catch finance teams and their stakeholders off guard, because nothing about the underlying business has changed — only how it's reported. Understanding the mechanics matters as much as understanding the rule.

The balance sheet gets bigger on both sides: the new right-of-use asset increases total assets, and the new lease liability increases total liabilities. Because the liability side typically outweighs the depreciating asset side over time, gearing and leverage ratios generally worsen — sometimes significantly, for lease-heavy businesses like retailers, hospitality operators and healthcare providers.

In the profit and loss account, the single straight-line rental charge disappears and is replaced by two separate lines: depreciation of the right-of-use asset (usually straight-line) and interest on the lease liability (calculated on the reducing balance, so it's higher in earlier years and tapers over the lease term). Added together, this front-loads the total expense recognised in the early years of a lease compared with the old, flat operating-lease charge — even though the cash paid to the landlord hasn't changed at all.

Perhaps the most counter-intuitive effect: EBITDA typically goes up. Rent used to sit above the EBITDA line as an operating expense. Now it's gone, replaced by depreciation and interest — both of which sit below EBITDA. So a business can look more profitable on an EBITDA basis and simultaneously look more leveraged and worse-covered on interest, purely as a mechanical consequence of the accounting change, with no change whatsoever to the underlying economics.

This is exactly why the covenant conversation matters. Many banking facilities and loan agreements set gearing, leverage or interest cover covenants by reference to the financial statements — and if those covenants weren't drafted with "frozen GAAP" wording or otherwise adjusted for this change, a business could technically breach a covenant purely because of the new lease accounting, not because anything has actually deteriorated. Firms should be talking to their lenders now, well ahead of their first FRS 102 (2024) year end, rather than discovering a covenant problem when the accounts are already drafted.

Who Is — and Isn't — Affected

Not every entity reporting in the UK and Ireland is caught by this change. Micro-entities reporting under FRS 105 are not affected by the new lease accounting rules at all — they continue to account for leases exactly as before. That said, FRS 105 preparers shouldn't assume they're untouched by the Periodic Review altogether: they are affected by the separate revenue recognition changes introduced under the same amendments, which is a topic worth understanding in its own right.

Entities reporting under full FRS 102, including those applying the Section 1A reduced disclosure regime for small entities, are affected in full. There's a common misconception that "small entity" status somehow exempts a business from the new recognition and measurement requirements — it doesn't. Section 1A only reduces the disclosures a small entity has to give in its notes; it does not change how leases are recognised or measured on the balance sheet. In fact, the Periodic Review went the other way on some points, making certain disclosures mandatory for small entities that were previously only encouraged or discretionary. If you've been assuming your small-entity clients or subsidiaries get a lighter version of this change, it's worth revisiting that assumption now.

For the fuller picture of what else moved under this set of amendments — revenue recognition, the fair value and financial instruments changes, and more — it's worth reading everything else that changed under the FRC's Periodic Review 2024 alongside this lease-specific guide.

Keep an Eye on the Latest FRC Guidance

The Periodic Review 2024 amendments aren't a static, one-off document that was finalised in 2024 and then left alone. The FRC published further clarifications to the amendments in March 2026, alongside a separate "adapted formats" amendment that doesn't take effect until 2027. If you or your advisers have been working from the original 2024 documents without checking for updates, it's worth pausing to check the latest guidance — in particular Factsheet 11, which deals specifically with lessee lease accounting under the new regime, rather than relying on materials that may already be a step behind.

How to Prepare: A Practical Checklist

With the effective date now well within most organisations' current financial year, preparation shouldn't wait for the audit to start asking questions. A sensible approach looks something like this:

• Identify every lease. Pull together a complete register of property, vehicle, equipment and other leases — including ones that might not obviously look like "leases" on paper but meet the definition in substance.
• Gather the data you'll need. Lease term, payment schedule, extension and termination options, any residual value guarantees, and a defensible discount rate (whether incremental borrowing rate or the simplified OBR) for each lease or portfolio.
• Assess the impact on your balance sheet and covenants. Model the effect on gearing, leverage and interest cover before it happens, not after — and start the lender conversation early if covenant headroom looks tight.
• Consider which exemptions and expedients apply. Work through the short-term and low-value exemptions lease by lease, and decide which of the transition practical expedients you'll rely on — then document your reasoning.
• Update your systems and processes. Spreadsheet-based lease tracking becomes much harder to maintain once you're calculating depreciation and effective-interest charges on dozens or hundreds of leases every period; many finance teams are moving to dedicated lease accounting software well ahead of their first affected year end.

Why It Matters

This isn't a cosmetic tweak to a footnote. For any organisation with a meaningful lease portfolio, it changes the shape of the balance sheet, the pattern of profit recognition, and the ratios that lenders, investors and boards use to judge financial health — all without a single pound of extra cash changing hands. Getting ahead of it means fewer surprises at year end, a smoother audit, and a much easier conversation with your bank when the numbers move.
