The FRS 102 lease changes are not something to prepare for anymore. For a client with a 31 December 2026 year end, they are in the accounts on your desk right now.
Retrofitting lease data across a client base is the kind of job that does not look big until you start it. Every property lease, every company car, every piece of financed equipment has to be found, measured and brought onto the balance sheet, and for December year ends the deadline to do that is the current filing cycle, not a future one.
This post covers what changed, which clients it hits, the leases you can still leave off, and how first-time adoption actually works at transition.
What changed in FRS 102 lease accounting?
The FRS 102 periodic review has replaced the old operating and finance lease split for lessees with a single on-balance-sheet model. For most leases, the lessee now recognises a right-of-use asset and a lease liability, effective for accounting periods beginning on or after 1 January 2026, with early application permitted.
The model is based on IFRS 16, but simplified for FRS 102. It is not IFRS 16 itself, and the simplifications matter in practice, particularly on transition and on the discount rate.
The effect on the accounts is a change in shape as well as in numbers. Instead of a rent expense in the profit and loss account, the lessee now carries an asset it depreciates and a liability it unwinds, so the charge splits into depreciation and interest. The periodic review also brought in a new five-step revenue recognition model on the same 1 January 2026 effective date, which is worth flagging to clients in the same conversation even though it is a separate change.
Which leases come onto the balance sheet
Most leases that used to sit off balance sheet as operating leases now come on.
For a typical trading company that means the obvious things: the lease on the office or the trading premises, company cars, and equipment taken on longer financing arrangements. Each of those becomes a right-of-use asset with a matching lease liability, measured at the present value of the future lease payments.
This is the part clients feel, because it changes the look of the balance sheet. Net assets can move, gearing ratios change, and anything with a covenant tied to the balance sheet needs checking before the accounts are finalised.
The leases you can still leave off
Two exemptions keep the smallest items off the balance sheet, and they are worth applying deliberately rather than by default.
- Short-term leases. Leases with a term of 12 months or less, with no purchase option, can be kept off balance sheet and expensed as before.
- Low-value asset leases. Leases of low-value assets can also be left off. The standard points to items like laptops, office furniture and phones as low value, and is clear that cars, heavier equipment, aircraft, land and buildings are not.
Used well, these two exemptions stop the exercise becoming about tagging every printer and handset, and keep the focus on the leases that actually move the numbers.
Which clients this hits, and which it does not
The clients most affected are ordinary trading companies with premises, vehicles or financed equipment. For those, this is a real piece of transition work in the current cycle, not a disclosure tweak.
The question every practice asks first is about the smallest clients, and the answer is clear: FRS 105 micro-entities are outside the lease changes. A micro-entity continues to account for leases as it does now, so the bulk of the very smallest client base is unaffected. The work concentrates in the FRS 102 and FRS 102 Section 1A population.
How first-time adoption works
Transition is where the detail lives, and FRS 102 has kept it deliberately simpler than a full retrospective restatement.
The approach is modified retrospective. A lessee does not restate its comparatives. Instead, it recognises the cumulative effect of first applying the amendments as an adjustment to the opening balance of retained earnings at the date of initial application.
From there the mechanics are:
- Measure the lease liability as the present value of the remaining lease payments, discounted at the lessee’s incremental borrowing rate, or an obtainable borrowing rate.
- Measure the right-of-use asset. The practical route for most firms is to set it equal to the lease liability, adjusted for any prepaid or accrued lease payments already on the balance sheet. A lessee already preparing IFRS 16 figures can instead carry over its IFRS 16 right-of-use asset and liability at the date of initial application.
- Apply the transition expedients where they save time without distorting the result.
The expedients are the part worth knowing, because they take real work out of a portfolio:
- Apply a single discount rate to a portfolio of leases with reasonably similar characteristics.
- Use hindsight when assessing the lease term, for example whether a break or renewal option is likely to be exercised.
- Choose not to reassess whether contracts in place at the date of initial application are, or contain, leases.
A worked example (illustrative)
Take a client with a five-year property lease, £20,000 payable annually in arrears, and an incremental borrowing rate of 6 per cent.
The lease liability at transition is the present value of the five remaining payments, which is roughly £84,250. Under the practical route, the right-of-use asset is recognised at the same figure, adjusted for any rent prepayment or accrual already in the books. From that point the asset is depreciated over the lease term and the liability unwinds at 6 per cent, so the single rent expense becomes a depreciation charge plus an interest charge.
These figures are illustrative and should be confirmed against the client’s actual terms. The judgement that moves the numbers most is the discount rate, which is why it is worth setting a consistent, defensible basis across the client base rather than deciding it job by job.
The knock-on effects worth raising with clients
The accounting change has consequences beyond the balance sheet, and clients are better told before the year end than after.
- Covenants and ratios. Bringing leases on balance sheet increases both assets and liabilities, which can move gearing and other balance-sheet ratios. Any loan covenant measured on those ratios should be checked against the new figures.
- Tax. The transition does not follow the accounting one for one. Spreading rules allow the transitional adjustment to be brought in for tax over a period based on the weighted average of the remaining lease terms, so the tax effect is smoothed rather than landing all at once.
- Distributable reserves. Because the cumulative effect goes to opening retained earnings, it can affect reserves, which is worth a look where a client is close to its distributable limit.
None of these is a reason to delay. They are reasons to have the conversation early, while there is still time to plan around them.
What to gather from clients, and how to make it repeatable
First-time adoption is, in the end, a data exercise, and the firms that handle it well treat it as one.
The useful step is a standard lease information request: the lease term, the payment amounts and timing, any break or renewal options, and enough to set the discount rate. Capture that once in a consistent format and next year is a roll-forward rather than a fresh hunt through the client’s filing cabinet.
Doing that the same way for every affected client is the difference between a controlled transition and twenty slightly different ones.
Where Active fits
The hard part of this change is not understanding the model. It is making sure the same lease is treated the same way by two people in two offices during a transition year, when the judgements behind it are easy to make differently.
That is a standardisation problem, and it is what Active is built for. Active builds the accounts dataset from Xero, QuickBooks Online, FreeAgent or a CSV trial balance and produces iXBRL tagged accounts ready to file with Companies House, with the treatment carried in the production process rather than in whichever file someone last opened. In a transition year, that is what turns first-time adoption into a controlled rollout instead of a series of reworks.

Frequently asked questions
Does IFRS 16 apply to FRS 102?
No. The new FRS 102 lease model is based on IFRS 16 and takes the same on-balance-sheet approach, but it is a separate, simplified set of requirements within FRS 102. It is not IFRS 16 itself, and some of the measurement and transition rules are deliberately simpler than the full IFRS standard.
When does FRS 102 adopt the new lease model?
The revised lease requirements are effective for accounting periods beginning on or after 1 January 2026, with early application permitted if the full package of periodic review amendments is adopted together. For a client with a 31 December 2026 year end, the first affected accounts are the ones being prepared now.
Are FRS 105 micro-entities affected by the lease changes?
No. FRS 105 micro-entities are outside the revised lease accounting model and continue to account for leases as they do currently. The on-balance-sheet right-of-use model applies to entities reporting under FRS 102, including those using the Section 1A reduced disclosures.
Do you have to restate comparatives on transition?
No. Transition uses a modified retrospective approach, so comparatives are not restated. The cumulative effect of first applying the amendments is recognised as an adjustment to the opening balance of retained earnings at the date of initial application.
