How to buy a business in the UK
A practical, step-by-step guide to buying a small or medium UK business, from working out your budget through to completion and handover.
Overview
Buying an established business can be a faster, lower-risk route to running your own company than starting from scratch: the customers, the revenue, the staff, and the systems are already there. But the process has its own language and its own pitfalls, and most first-time buyers go in without a clear map of what happens when.
This guide walks through the whole journey in order, with realistic timings and honest notes on where you should take professional advice. It is written for owner-operators buying their first business, not for private equity. Where Fair Handover makes a step simpler or cheaper, we say so.
Step 1: Get clear on what you are looking for, and your budget
Before you browse a single listing, write down what you actually want: a sector you understand or can learn, a location you can realistically run, a size you can afford, and a lifestyle you want afterwards. Then work out your real budget. That is your available cash plus what you can sensibly borrow, minus a buffer for working capital and the first few months. Buyers who skip this end up chasing businesses they cannot fund or do not want to run.
Step 2: Search and shortlist
Browse by sector and location to learn what is available and at what price. Public listing details are visible without signing up. Shortlist a handful that fit your budget and your skills, and do not be put off by a business that needs work; a fixable problem is often where the value is.
Step 3: Make contact and sign the NDA
When a listing looks right, sign the NDA to unlock the full confidential details and open secure chat with the seller. On Fair Handover your real contact details stay hidden until you choose to share them. Be straightforward about who you are and how you would fund the purchase; sellers prioritise buyers who can clearly proceed.
Step 4: Review the information and value the business
Ask for three years of accounts, recent management figures, and the basis for the asking price. Work out what you think the business is worth and what it is worth to you specifically. Our guide on valuing a business before you buy covers the methods and the typical UK multiples.
Step 5: Make an offer (heads of terms)
Once you are seriously interested, put your headline terms in writing. The heads of terms (or letter of intent) sets out price, payment structure, what is included, an exclusivity period, and a target timeline. It is mostly non-binding, but it frames everything that follows.
Step 6: Due diligence
This is where you verify what you have been told. Expect 4 to 12 weeks of detailed checking across financials, tax, contracts, employment, customers, and any legal or regulatory matters. Use an accountant and a solicitor. Surprises found here are the most common reason buyers renegotiate or walk away, which is exactly what diligence is for.
Step 7: Legal completion
Your solicitor and the seller's solicitor finalise the purchase agreement (a Share Purchase Agreement or Asset Purchase Agreement), the warranties, and the disclosure letter. Funds transfer on completion day, and ownership passes to you.
Step 8: Handover and the first 100 days
Most deals include a handover period where the seller stays on to introduce you to customers, suppliers, and staff and to transfer the knowledge in their head. Agree the length and shape of this in advance. Resist the urge to change everything at once; spend the first few months learning how the business really works before you start reshaping it.

Frequently asked questions
- How long does it take to buy a business?
- From first serious enquiry to completion, four to nine months is typical. A well-prepared seller and a straightforward business can complete in three to four months; complex or larger deals can run to a year. The due diligence and legal phases usually take the most time.
- Do I need a solicitor and an accountant?
- For anything beyond a very small asset purchase, yes. A solicitor handles the purchase agreement, warranties, and lease or contract transfers; an accountant verifies the numbers and advises on the tax-efficient structure. Their fees are small relative to the price and they routinely save buyers far more than they cost by catching problems early.
- Should I buy the shares or just the assets?
- It depends. Buying shares means buying the company whole, including its history, debts, and liabilities. Buying assets means cherry-picking what you want (equipment, stock, goodwill, contracts) and leaving liabilities behind, though some contracts and the lease may need consent to transfer. Sellers often prefer a share sale for tax reasons; buyers often prefer an asset sale for safety. Take advice on which fits your deal.
- How much money do I need upfront?
- More than just the deposit. Budget for your equity contribution (often 20 to 50 percent of the price if you are borrowing), professional fees for your solicitor and accountant, and working capital to run the business through its first quieter months. Going in undercapitalised is one of the most common reasons new owners struggle.
