The Five-Week Countdown: Fire Safety Owners and the April Tax Year End

Update, November 2026. The October 2026 Budget announced that the Business Asset Disposal Relief lifetime limit will fall from £1 million to £500,000 for qualifying disposals from the start of the 2027 to 2028 tax year in April 2027. Relief already claimed counts towards the limit, and the 18% rate does not change. For tax, the date of an unconditional contract normally counts as the date of disposal rather than completion, and specific rules will apply to contracts signed before the change that complete after it. Where this page quotes a different limit, rate or date, this note takes priority. Take advice on your own position. What the change means for owners.

The binding contract fixes the rate, and that date is rarely where you think it is

The date that governs a business disposal for tax is normally the day the sale contract becomes binding with no conditions left, which is often but not always completion day. Not the day you agreed a price with an acquirer, not the day heads of terms, the outline of the deal, were signed, not the day your accountant first ran the figures. That date is what places the disposal in one tax year rather than the next, and everything before it is preparation.

Business Asset Disposal Relief, the reduced tax rate for owners selling a business they work in, was 10% on qualifying gains up to a £1m lifetime limit for a disposal in or before Apr 2025, and 14% for one in the 2025/26 tax year. The tax rate then went up again, to 18%, in Apr 2026. All of that was announced at the Autumn Budget in Oct 2024, so nothing about it was a surprise; the only variable was which side of the line a sale landed on.

Since Budget day, rules have stopped owners signing early just to lock in a lower rate: a contract entered into before a rate change and completed afterwards is examined on its purpose rather than taken at its date. That is a conversation for your own tax adviser rather than something to design a deal around, and it is the reason the honest answer to "can we get it done before April" is usually no.

A fire safety sale takes longer than a tax year end leaves you

A sale of an owner-managed fire safety business usually occupies months rather than weeks, and diligence here, the buyer's detailed checking of the business, is heavier than in most trades because so much of what is being bought is documentary. An acquirer will want certification records, service contracts with renewal dates, engineer qualifications, commissioning certificates and the audit history behind the scheme registration. None of that is quick to assemble under pressure.

So if the tax year end is five weeks away and nothing has started, the useful question is not how to compress a sale. It is how to use the coming twelve months so that the following year end is a real option rather than a theoretical one.

There is one honest exception, and it is worth naming. Where a process is already well advanced, heads of terms signed, diligence under way, solicitors instructed on both sides, the tax year end is a legitimate thing to work towards, and a few weeks of concentrated effort genuinely can matter. That is a different situation from starting in March, and the owners it applies to already know who they are.

There is a second reason not to hurry. The things that move the price, contract documentation, certification currency, a named technical authority who is not the owner, customer spread, are all built over quarters. A rushed process tends to lose more on the headline number than the rate step costs, which makes urgency an expensive way to save tax.

What five weeks is genuinely long enough to achieve

Five weeks will not produce a completion, but it will produce most of a diligence pack, and that has value in every scenario including never selling. Start with the contract base: every service and maintenance agreement in one schedule, with the client, the site count, the renewal date, the annual value and whether it renews automatically or by re-tender.

Then the certification file. Confirm the BAFE registration scope is current, that the nominated individuals behind it are the people still doing the work, and that engineer qualifications and CPD records are filed rather than assumed. Anything out of date is quicker to fix in March than to explain in diligence.

Then the accounts. Three years of statutory accounts plus management figures split between contracted servicing income and project work, because that split is the first thing an acquirer models and the last thing most owners have to hand. An owner who does this in a quiet March spends the following autumn answering questions in days rather than weeks.

Do the employment file at the same time. Contracts of employment, the current engineer list with qualifications and start dates, holiday and pension records, and a note of anything unusual in anyone's terms. Staff transfer with the business when it changes hands, so a buyer reads that file closely, and it is the one owners most often find is incomplete when somebody finally asks for it.

Tax and legal advice on a sale comes from your own advisers, and it helps to know who you will need, and when to bring them in.
