How to buy a business in the UK: a step-by-step guide

To buy a business in the UK you typically follow ten stages: set your criteria and budget, get an early view on funding, find a target, sign a confidentiality agreement and review the information, value the business and make an offer, agree heads of terms, carry out due diligence, secure finance, negotiate the legal documents, and complete and take over. This guide is for first-time buyers, managers buying their employer and owners making their first acquisition, and it walks through each stage in order. Smart Funding Solutions is a broker, not a lender. We arrange purchase funding from around £10,000 to £500,000+, with larger facilities available in suitable cases, through our acquisition finance service. If you are still deciding whether borrowing is right for you at all, read our guide on whether to take a loan to buy a business first.

02Step 1: Decide what you want to buy and what you can afford

Start by defining the kind of business you want and the money you can put in yourself, because both narrow the search and shape every later decision.

Write down the sector, size, location and role you want, and what you are not prepared to take on. A business that depends entirely on its owner's personal relationships, for example, is a very different purchase from one with a capable management team. Then work out your personal contribution: savings, pension lump sums and other capital you are prepared to risk. Lenders expect buyers to invest meaningfully in the deal; our guide to the deposit needed to buy a business explains what that usually means.

03Step 2: Get an early view on funding

Talking to a funding specialist before you find a target tells you the realistic size of deal you can pursue and makes your offers more credible to sellers.

Acquisition lenders look at the target's profits and cash flow, the buyer's experience and contribution, and the security available. An early conversation can indicate whether a deal of a certain size is likely to be fundable, which structures are common in your sector, and what lenders will want to see. It also allows you to show a seller that you have thought about funding, which matters when several buyers are interested.

04Step 3: Find a business to buy

Most businesses are found through business brokers and online listings, direct approaches to owners, and personal networks such as accountants, solicitors and industry contacts.

Listed businesses are easy to find but often attract competition. Off-market approaches to owners nearing retirement can lead to better information, a cooperative seller and more flexible terms. If you already work in the business, a management buyout may be the natural route; an outside team buying in follows a similar process through management buy-in finance. Our guide on how to find a business to buy covers search methods in detail.

05Step 4: Sign a confidentiality agreement and review the information

Before sharing detailed figures, a seller will normally ask you to sign a non-disclosure agreement, after which you receive an information memorandum and the accounts.

Use this stage to test whether the business matches your criteria. Look at several years of accounts, the trend in sales and margins, customer concentration, staff and premises. Check the company's filing history and any registered charges at Companies House. Meeting the owner and visiting the premises tells you a great deal that figures cannot, including how dependent the business is on the seller personally.

06Step 5: Value the business and make an offer

The value of a business depends mainly on its sustainable profits, the risk attached to them and the assets that come with it, and your offer should reflect what the business can afford to pay for itself as well as what the seller wants.

Common approaches include a multiple of adjusted profit, asset-based valuations for asset-heavy businesses and, in some professional sectors, a multiple of recurring fees. Adjust the seller's reported profit for one-off items, the owner's salary and personal costs, and the cost of replacing the owner's work. Our guide on how to value a business explains each method. Your offer should also say how you intend to pay: how much at completion, how much deferred and on what conditions.

07Step 6: Agree heads of terms

Heads of terms are a short, mostly non-binding document that records the agreed price, structure, payment terms, conditions and timetable, usually with a binding period of exclusivity.

This is a critical stage for funding. The choice between buying shares or assets, the split between cash and deferred payments, the seller's handover and the working capital the business must contain all affect how much you need to borrow and what lenders will accept. Our guide to heads of terms when buying a business includes a checklist of what to cover. Deferred payments to the seller are explained in our guide to deferred consideration.

08Step 7: Carry out due diligence

Due diligence is the detailed investigation of the business you are buying, covering finances, tax, legal matters, employees, customers and assets, so you know exactly what you are taking on before you commit.

Your accountant will usually examine the quality of earnings, working capital and tax position, while your solicitor reviews contracts, leases, employment matters and any litigation. Specialist checks may cover property, environmental issues, technology or regulatory compliance. Findings can lead to a renegotiated price, specific indemnities or more of the price being deferred. See our guide to business acquisition due diligence.

09Step 8: Secure the finance

Most buyers fund a purchase with a combination of their own money, borrowing and payments deferred to the seller, and the finance application runs in parallel with due diligence.

Typical sources include a term loan sized on the target's profits, asset-based facilities secured on debtors, stock or equipment, and property finance where premises are included. Lenders will want the heads of terms, the target's accounts, your personal financial information and a forecast for the business under your ownership. Plan the business's day-one cash needs at the same time; our page on working capital after an acquisition explains why this is often overlooked. Our guide comparing business acquisition lenders explains how funders differ.

As one example, our accountancy practice acquisition case study describes a £137,500 acquisition facility for an accountancy firm buying another practice, presented to lenders on agreed heads of terms.

10Step 9: Negotiate the legal documents

The legal stage turns the heads of terms into a binding sale agreement, supported by a disclosure letter from the seller and any ancillary documents such as leases, consultancy agreements and security for deferred payments.

The sale agreement contains warranties, which are statements about the business that the seller stands behind, and indemnities for specific known risks. The seller's disclosure letter lists exceptions to the warranties, so read it carefully. On an asset purchase, employees usually transfer automatically under TUPE, and contracts and leases may need consent to be transferred. Your lender's solicitor will also prepare the loan and security documents, which must be ready for completion.

11Step 10: Complete the purchase and take over

At completion the documents are signed, the lender releases funds, the seller is paid, any existing charges over the business are cleared and ownership passes to you.

The work then shifts to the handover. Agree in advance how the seller will introduce you to staff, customers and suppliers, how long they will stay involved, and what you will and will not change in the first few months. Tell the bank, HMRC, insurers and key suppliers about the change of ownership, and update the Companies House record as needed. Monitor cash closely: the first months under new ownership are when unexpected costs and customer caution are most likely to appear.

12How long does it take to buy a business?

Buying a business commonly takes several months from first approach to completion, and the search before that can take much longer. The timetable varies widely with the size and complexity of the deal, the state of the seller's records and how quickly each party's advisers work.

The period after heads of terms is usually the most intense, because due diligence, the finance application and legal drafting all run at once. Delays most often come from incomplete information, landlord or regulatory consents, issues found in diligence and late engagement with lenders. Lender decisions can come within a few working days in straightforward cases, but the full funding process, including legal work on security, takes longer, so start it early.

13Mistakes first-time buyers often make

The most common mistakes are avoidable with preparation and good advice.

• Falling in love with a business before testing whether it can carry the debt.
• Relying on the seller's figures without independent due diligence.
• Leaving funding until after heads of terms are signed, then running out of exclusivity.
• Paying too much in cash at completion when the seller would accept some deferral.
• Underestimating professional fees, stamp duty on share or property purchases, and integration costs.
• Planning no working capital for the first months of ownership.
