On 1 January 2026 the biggest overhaul of UK GAAP in a decade took effect. The Periodic Review 2024 changes to FRS 102 — the standard most UK companies and LLPs report under — rewrote two of the most fundamental areas of any set of accounts: how leases are recognised and how revenue is measured. For the firms that advise owner-managed businesses, this is not a technical footnote. It is the single biggest reason a client will be surprised by their own numbers this year, and the single biggest reason to be the accountant who warned them first.
This post is about what changed, what it does to a client's balance sheet, and why the firm that explains it before year-end wins the work the firm that stays silent will lose.
What actually changed
Two changes carry almost all the impact, and a third raises the workload.
Leases move onto the balance sheet. For lessees, FRS 102 has dropped the old distinction between operating and finance leases. Most leases — the office, the vehicles, the equipment that used to sit quietly in the notes as an annual rental cost — now appear on the balance sheet as a right-of-use asset and a matching lease liability. A business that rents its premises and leases its vans can see its balance sheet grow materially overnight, with no change whatsoever to the underlying business.
Revenue recognition is rebuilt around control. FRS 102 now aligns closely with the international standard IFRS 15. Revenue is recognised when, or as, control of goods or services transfers to the customer, replacing the older test based on the transfer of risks and rewards. For service businesses, contractors, and anyone billing across multiple periods or with bundled deliverables, the timing of recognised revenue can shift — which moves reported profit between years.
Small companies face more disclosure. Entities using the Section 1A reduced-disclosure regime, which is most small companies, now face additional disclosure requirements covering areas such as going concern, provisions, leases, deferred tax, and dividends. The reduced-effort filing got less reduced.
Why this is a client conversation, not a compliance task
Here is the part most firms will miss. These changes do not alter how a business actually trades, but they change what its accounts say about it — and that has consequences a business owner feels.
A bigger balance sheet with new lease liabilities changes gearing ratios. A shift in the timing of revenue moves reported profit between years. Both can affect the covenants a business agreed with its bank, the KPIs an investor watches, and the figures a buyer scrutinises in due diligence. A client who discovers at year-end that their accounts now show a lease liability that tips them through a covenant threshold is a client who is angry, frightened, and asking why nobody told them.
The firm that modelled the impact in advance — that sat the client down and said "your numbers are going to look different this year, here is why, and here is what we have already discussed with your bank" — is the firm that just became indispensable. This is precisely the kind of proactive, advisory relationship covered in our complete guide to digital marketing for accounting firms: the value is not the compliance, it is being the adviser who saw it coming.
The opportunity for proactive firms
Every owner-managed business affected by these changes is, right now, a potential advisory conversation. Covenant reviews, restating comparatives, explaining the new numbers to a board or a lender, helping a client understand why their profit moved without their business changing — none of that is commodity compliance, and clients pay for judgement.
It is also an acquisition opportunity. Business owners are already typing "FRS 102 changes 2026", "are leases on the balance sheet now", and "why has my profit changed" into Google. The firm whose page answers those questions clearly is the firm that earns the enquiry from a business whose current accountant said nothing. Regulatory change is the most reliable trigger for a client to reconsider who advises them — the same dynamic we documented in our analysis of the 2026 UK accounting client switching window.
The cost of staying quiet
The downside is not neutral. A firm that processes the new figures without ever explaining them looks reactive at best and asleep at worst. The client who gets blindsided by a covenant breach, or who finds out from their bank rather than their accountant, does not just feel let down — they start looking. And the well-optimised competitor who published a clear FRS 102 explainer, ranked for it, and used it to start conversations is the firm they find.
Silence during a mandated change is not safe. It is market share handed to whichever firm decided to be visible and proactive while you stayed busy in the back office.
Visibility is the deliverable
Technical competence on FRS 102 is assumed — every qualified firm can apply the standard. What separates the practices that grow from this transition from the ones that merely cope is whether a worried business owner can find them at the moment they go looking.
That is a marketing problem with concrete parts. It means a fast, clear page targeting the exact phrases clients search, which is the work of search engine optimisation. It means that page turning a reader into a booked call rather than a bounce, which is the work of website design and development. And it means a proactive note landing in every affected client's inbox before year-end, which is the work of email and lifecycle marketing. The full framework for UK firms is set out on our page for digital marketing for UK accounting firms.
What to do this week
Publish one authoritative page explaining the FRS 102 changes in plain English for a non-accountant business owner: what moved onto the balance sheet, why reported profit may shift, and what it means for covenants and KPIs. Identify the clients most exposed — those with significant leases or multi-period revenue — and contact them before their year-end, not after. Then make sure the page is fast, findable, and connected to a clear way to book a conversation.

Frequently asked questions
FAQs
What are the main FRS 102 changes from January 2026?
The Periodic Review 2024 changes took effect for accounting periods beginning on or after 1 January 2026. The two biggest are lease accounting, where most leases now sit on the balance sheet as a right-of-use asset and a lease liability rather than as an annual rental cost, and revenue recognition, which now aligns with IFRS 15 and is based on the transfer of control. Small entities using Section 1A also face additional disclosures.
Why would these changes affect my bank covenants?
Putting leases on the balance sheet increases liabilities and assets, which changes gearing and other ratios, while the revenue changes can move reported profit between periods. If your loan agreements set covenants based on those ratios or on profit, the new accounting presentation can affect them even though your business has not changed. This is why it is worth reviewing covenants before your year-end.
Is this a marketing opportunity for accounting firms?
Yes. Business owners are searching for clarity on what the changes mean, and most do not understand why their numbers will look different. A firm that publishes a clear explainer, ranks for those searches, and proactively contacts affected clients captures both retention and new enquiries from businesses whose current accountant stayed silent.
What happens to firms that do not communicate these changes?
The searcher finds whichever practice answered the question first, and the client who is blindsided by a covenant issue or an unexplained profit shift starts looking for a more proactive adviser. During a mandated change, staying quiet is lost trust and lost market share.
How does Triomatic Marketing help accounting firms with this?
