If you want to know how to buy a small business UK style, the short answer is this: you find a business that fits your skills and budget, you check its numbers and contracts carefully (this is called due diligence, which means investigating before you commit), you agree a fair price, and you complete the sale through a solicitor with a written contract. Do those four things properly and you buy something that already has customers, staff and cash flow. Rush them and you can inherit debts, disputes and problems the seller was quietly hoping to pass on.
This guide walks through the whole process for a typical UK deal: finding and valuing a business, running due diligence, structuring the purchase (assets versus shares), and the legal steps to completion. It uses realistic figures for a business turning over roughly £200,000 to £1m, the size most first-time buyers actually target.
Why buy rather than start from scratch?
Starting a business means building demand from zero. Buying one means the demand already exists. You get an established customer base, trained staff, supplier relationships, a trading history the bank can see, and often a recognisable local name. That is why many owners choose acquisition over launch, especially in trades, hospitality, care, professional services and e-commerce.
The trade-off is cost and risk. You pay a premium for something that already works, and you take on whatever is hiding under the bonnet. The whole point of due diligence is to find those hidden problems before you sign.
Step one: find the right business and set a budget
Businesses come to market through commercial brokers, online marketplaces (BusinessesForSale, Daltons, Rightbiz), trade press, accountants, and plain word of mouth. Off-market deals, where you approach an owner directly, often produce the best value because there is no bidding pressure.
Before you view anything, be honest about your budget. Your purchase funds usually come from savings, a bank loan, or a mix. Many acquisitions also use “deferred consideration”, where you pay part of the price over time out of future profits, which reduces the cash you need on day one. If you are borrowing, get an indication from your bank early, and make sure you have the right business bank account set up for the trading you plan to do.
Step two: value the business realistically
Valuation is where emotions and reality collide. Sellers remember the good years; buyers should price on sustainable performance. Small businesses are usually valued in one of three ways.
- Multiple of profit. The most common method. You take adjusted net profit (often called SDE, seller’s discretionary earnings, or EBITDA for larger deals) and apply a multiple. For small UK businesses this is frequently in the range of 2 to 4 times, higher for businesses with recurring revenue and strong systems, lower for those that depend heavily on the owner.
- Asset-based. You value the tangible assets (stock, equipment, vehicles, property) plus goodwill. Useful for asset-heavy businesses like manufacturing or a shop with fittings.
- Revenue multiple. Used for fast-growing or subscription businesses where profit is being reinvested. Less common for traditional SMEs.
Whichever method you use, “normalise” the accounts first. Add back the current owner’s above-market salary, one-off costs and personal expenses run through the business, then subtract a fair salary for whoever will actually run it after purchase. A business that only makes money because the owner works 70 hours a week for nothing is worth far less than it looks.
A quick worked example
Say a local cleaning company shows £60,000 net profit. You add back the owner’s £15,000 excess salary and a £5,000 one-off legal cost, giving £80,000 adjusted profit. You then subtract £30,000 for a manager to replace the owner, leaving £50,000. At a 3x multiple, that is a £150,000 valuation, before any adjustment for assets, debt or working capital.
Step three: run proper due diligence
Due diligence is your investigation of everything the seller claims. It normally happens after you have agreed heads of terms (an outline of price and conditions) but before contracts are signed. Give yourself several weeks and involve an accountant and a solicitor.
Cover at least these areas:
- Financial: three years of accounts, management accounts, bank statements, VAT returns, and aged debtor and creditor lists. Check that profits are real and cash is actually collected. A 13-week cash flow forecast for the business you are buying is one of the most useful things you can build.
- Tax: confirm the business is up to date with HMRC on Corporation Tax, PAYE and VAT. Understand which VAT scheme it uses and whether it is registered, because that affects both price and your own obligations.
- Legal: customer and supplier contracts, the lease, licences, and any ongoing disputes. Check whether key contracts can be transferred to a new owner.
- People: employee contracts, salaries, holiday owed, pensions and any grievances. If you buy the trade, TUPE rules usually mean staff transfer to you on existing terms, so read our guide to UK employment obligations before you commit.
- Customers: is revenue spread across many clients or dangerously concentrated in one or two? Losing a single customer that is 40% of sales could sink the deal’s economics.
- Company records: for a limited company, check the filings at Companies House for accuracy, charges (loans secured on assets), and director history. Directors also now need to complete Companies House identity verification.
Step four: asset purchase or share purchase?
This is the single most important structural decision, and it changes your risk and your tax.
In an asset purchase, you buy specific assets and goodwill but not the legal company itself. Historic liabilities, debts and past claims generally stay with the seller. Most first-time buyers of a small business prefer this because it is cleaner.
In a share purchase, you buy the company’s shares, so you get the whole entity including its history, contracts, and any hidden liabilities. It can be simpler for transferring contracts and licences, and sometimes more tax-efficient for the seller, but you need stronger warranties and indemnities (promises and financial protections written into the contract) to cover unknown problems.
| Feature | Asset purchase | Share purchase |
|---|---|---|
| What you buy | Selected assets and goodwill | The whole company (shares) |
| Historic liabilities | Usually stay with seller | Transfer to you |
| Contract transfer | Often need renegotiating | Usually continue automatically |
| Stamp duty | Not on most assets | 0.5% stamp duty on shares |
| Buyer risk | Lower | Higher, needs strong warranties |
| Best for | First-time buyers, sole traders selling | Established companies, tax planning |
Step five: the legal process to completion
Once due diligence is done and you still want the business, the legal steps run roughly like this:
- Heads of terms: a short, mostly non-binding document setting out price, structure and key conditions.
- Sale and purchase agreement (SPA): the main contract, drafted by solicitors, containing warranties, indemnities, and what happens if promises turn out to be false.
- Disclosure letter: the seller’s formal list of anything that qualifies the warranties. Read it closely, this is where problems are legitimately confessed.
- Lease assignment or new lease: if premises are involved, the landlord must usually consent to the transfer.
- Completion: money changes hands, documents are signed, and you take control. You then notify HMRC, register as employer if needed, update insurance and, if buying shares, file changes at Companies House.
Budget for professional fees. A solicitor for a straightforward small acquisition often costs £2,000 to £7,000 plus VAT, and accountant due diligence a similar range, depending on complexity. It is money well spent against a five or six figure purchase.
The first 90 days after you buy
Completion is the start, not the finish. Reassure staff and customers quickly, keep the previous owner available for a handover period (build this into the contract), and resist the urge to change everything at once. Sort the practical basics early: transfer utilities and software, set up your own systems, confirm the insurance cover the business must legally have, and check the tools you inherit against something like the operations stack a sub-£1m business should be running.
Frequently asked questions
How much does it cost to buy a small business in the UK?
The purchase price depends entirely on profit and sector, but professional costs are separate. Expect solicitor and accountant fees combined of roughly £4,000 to £15,000 plus VAT for a typical small deal, plus any lender arrangement fees and, for share purchases, 0.5% stamp duty on the shares.
Can I get a loan to buy a business?
Yes. High street banks lend against acquisitions, often needing a deposit of 30% to 50% and a credible business plan. Government-backed options and challenger lenders exist too. Deferred consideration, where the seller is paid partly from future profits, is also common and reduces upfront borrowing.
How long does buying a small business take?
From agreed heads of terms to completion, a straightforward deal usually takes two to four months. Due diligence, lease consent from a landlord, and finance approval are the most common causes of delay.
Do employees transfer when I buy a business?
In most asset purchases of a trading business, TUPE regulations mean staff transfer automatically on their existing terms and length of service. You cannot simply cut pay or make redundancies because of the transfer, so factor the full wage bill and any holiday or pension liabilities into your valuation.
Is it safer to buy the assets or the shares?
For most first-time buyers an asset purchase is lower risk, because historic debts and claims generally stay with the seller. A share purchase can be simpler for keeping contracts and licences in place, but you inherit the company’s full history and need strong warranties and indemnities to protect yourself.
What to do next
- Set your budget and finance. Confirm how much cash you have and get an early indication from a lender before you view businesses.
- Line up your advisers. Appoint an accountant and a solicitor experienced in small business sales before you agree heads of terms, not after.
- Do the numbers yourself. Normalise the accounts, build a cash flow forecast, and stress-test the deal against losing a major customer.
- Read the official guidance. Review the gov.uk business support resources and check the target’s filings at Companies House before you commit.
