Most owners sell a business once. The buyer on the other side of the table may have bought dozens. That imbalance is the real problem with selling a business, and it is why so many owners accept a structure they do not fully understand, at a price that was decided by the condition of the business long before the first meeting. This guide sets out how a UK sale works from start to finish, so you know what is coming.
Step 1: decide what you want from the sale
Before anything else, write down the number you need, the date you want to stop, and what you want for your team and your customers. "As much as possible, as soon as possible" is not a plan. A clear answer narrows the buyers worth talking to and stops you accepting the first offer because it is there.
Step 2: choose the route
- A trade buyer: a company in your industry or a related one. Often pays the most where the fit is strong, and usually wants you to stay for a handover period.
- Private equity: usually for larger, growing businesses with a management team. You may be asked to keep a stake and stay on.
- Your management team: continuity and discretion, but often funded partly by payments to you over time. See management buyouts.
- An employee ownership trust: a sale to a trust for your staff, now with half the tax relief it had before November 2025. See employee ownership trusts.
- A family member or an individual buyer: common for smaller businesses, with its own funding and tax questions. See succession planning.
Step 3: prepare the business
This is where the price is really set. Buyers pay a multiple of profit they believe will continue without you, and they discount anything they cannot verify. The work that moves the price:
- monthly management accounts and an evidenced add-back register (see add-backs);
- a business that runs without you, with key relationships held by your team;
- customer contracts, a spread of customers and a credible growth story;
- clean legal and tax affairs, including your eligibility for Business Asset Disposal Relief;
- a data room built before anyone asks for it. The due diligence checklist lists what goes in it.
Step 4: put the right people on your side
- A corporate solicitor who does deals, not your usual high-street firm.
- An accountant or tax adviser who has handled sales like yours.
- A broker or corporate finance adviser if you want a wide search for buyers. They are usually paid largely on success, so ask exactly how, and what they earn if you sell to someone you introduced yourself.
The Harvest Club teaches the preparation. We do not broker sales or take fees from brokers, which is why we can tell you plainly what each route is likely to cost you.
Step 5: the deal itself
- Information: an anonymous profile, then a fuller information memorandum to interested buyers who sign a confidentiality agreement.
- Offers: indicative offers, meetings, and a preferred buyer.
- Heads of terms: the price, structure and timetable agreed in principle, often with a period of exclusivity.
- Due diligence: the buyer's investigation of your financial, legal, tax and commercial position. This is where unprepared businesses lose value.
- The sale agreement: warranties, indemnities, the price mechanism and any deferred or earn-out payments. Read our guide to earn-outs before you agree to one.
- Completion: signing, money and handover.
The five mistakes that cost owners most
- Going to market before the business can run without them.
- Judging offers on the headline price instead of what reaches them, after debt, deferred payments, earn-outs and tax.
- Letting exclusivity start before the data room is ready.
- Using advisers who have never done a deal of this size.
- Not knowing their own number, so any offer feels like a good one.
Where to start
Put a number on your business with the valuation calculator, then find the gaps a buyer will find with the Harvest Score. Both are free and take minutes. If you want help turning the gaps into a plan, that is what the Harvest Intensive is for.
Common questions
How long does it take to sell a business in the UK?
The sale process itself usually runs for months, from preparing information through due diligence to completion. The preparation that decides the price takes longer: six to twelve months of deliberate work is a sensible minimum, and more is better.
Do I need a business broker to sell my business?
Not always. Smaller businesses are often sold through brokers, larger ones through corporate finance advisers, and some owners sell directly to a buyer they already know. Whoever you use, you will still need your own solicitor and accountant, and you should understand how your adviser is paid.
Should I sell shares or assets?
Most owner-managed UK companies are sold as a share sale, where the buyer takes the whole company. Some buyers prefer to buy the assets and trade instead, leaving liabilities behind. The tax and legal consequences differ, so take advice early.
