On 30 October 2025, Chancellor Rachel Reeves delivered the Autumn Budget. For pest control business owners who had been keeping one eye on the rumour mill, the key question was simple: did they change the tax rules on selling a business? The answer is yes, and the changes are significant enough to warrant careful attention from anyone considering a sale in the next twelve months.
Business Asset Disposal Relief: The Headline Change
Business Asset Disposal Relief, which was previously known as Entrepreneurs' Relief, has been the cornerstone of tax-efficient business sales for years. Before the Budget, qualifying business owners could sell their business and pay Capital Gains Tax at a reduced rate of 10% on the first £1 million of qualifying gains, rather than the standard CGT rates of 10% or 20% depending on income.
The Budget changed this in two stages. From 30 October 2025, the BADR rate increased from 10% to 14%. This change took effect immediately, meaning any business sale completing from that date onwards is subject to the higher rate. From April 2026, the rate will increase again to 18%. The £1 million lifetime limit on qualifying gains remains unchanged.
To put this in context: a pest control business owner who sold their business in September 2025 and made a qualifying gain of £400,000 would have paid £40,000 in CGT under the old 10% BADR rate. The same sale completing today, in December 2025, would attract tax of £56,000 at the new 14% rate. And if that same sale were to complete after April 2026, the tax bill would be £72,000 at 18%.
What This Means in Pounds and Pence
Suppose you own a pest control business that a buyer is willing to purchase for £400,000. After deducting your base cost, which for most owner-managed businesses is relatively small, your qualifying gain is close to £400,000.
Each Budget carries the risk of further changes, and the direction of travel has been consistently towards higher rates and reduced reliefs for business sellers.
If you complete the sale before April 2026 at the current 14% BADR rate, your CGT liability would be £56,000. You would keep £344,000 before any other costs.
If you complete the sale from April 2026 onwards at the 18% BADR rate, your CGT liability would be £72,000. You would keep £328,000.
The difference is £16,000. For larger gains, it grows proportionally: £30,000 on a £750,000 gain, and £40,000 on the full £1 million lifetime limit. These are not trivial sums.
Employers' National Insurance: The Other Change That Matters
The Budget also confirmed an increase in Employers' National Insurance contributions from 13.8% to 15%, effective from April 2025. Alongside this, the threshold at which employers start paying NI was lowered from £9,100 to £5,000 per employee per year.
For pest control businesses with employed technicians, this is a meaningful increase in operating costs. A business with five technicians could see an additional £6,000 to £7,500 per year in employer NI alone, depending on salary levels.
This matters for valuations because it directly reduces net profit. A buyer will model their offer based on the profit they expect to inherit. If you are preparing for sale, make sure your financial projections reflect these increased costs so there are no surprises during due diligence.
Should You Rush to Sell Before April 2026?
This is the question that every pest control business owner with sale plans is now asking, and the honest answer is: it depends.
If your business is already well prepared, completing before April 2026 would save you money. The tax saving is real and quantifiable.
If your business is not ready, however, rushing to market is almost always a mistake. Selling for £350,000 instead of £400,000 because you were not properly prepared, just to save £16,000 in CGT, is poor arithmetic.
The right approach is to assess honestly where you stand. If you are close to ready, accelerate and aim to complete before April 2026. If you are not, start preparing now with a realistic timeline and focus on maximising the sale value rather than minimising the tax rate.
The Window Is Narrowing, But It Has Not Closed
At the time of writing, there are approximately four months until the April 2026 BADR rate increase takes effect. A pest control business sale typically takes three to six months from going to market to completion, which means the window for completing a sale at 14% is tight but not impossible for businesses that are already substantially prepared.
For those who cannot realistically complete before April 2026, the 18% rate is still significantly lower than the standard higher CGT rate of 24% that would apply without BADR. The relief has become less generous, but it has not been abolished. Qualifying business owners will still benefit from a preferential rate on the first £1 million of gains.
What You Should Do Next
Speak to your accountant. Make sure you understand your personal CGT position, including how much of your £1 million BADR lifetime limit you have already used (if any), and what the tax implications of a sale would be at both 14% and 18%.
Get a realistic valuation. Understand what your business is actually worth in the current market, not what you hope it might be worth. A valuation based on the specifics of your contract book, team, and geography will give you the information you need to make a sound decision.
Assess your readiness. Are your accounts clean? Are your contracts formalised? Is your team stable? Could the business operate without you for three months? If the answer to all of these is yes, you are in a strong position to move quickly. If not, start addressing the gaps now.
The Autumn Budget has changed the arithmetic of selling a business. It has not changed the fundamentals. A well-prepared pest control business with strong recurring revenue, qualified staff, and good documentation will still attract multiple buyers and achieve a strong price. The difference now is that timing matters more than it did six months ago, and every month of delay after April 2026 carries a tangible cost.
