How to Sell Your Business in the UK (Step-by-Step Guide)

Preparation is the most underestimated phase of a business sale. Buyers and their advisers will scrutinise your financials, contracts, operations, and team. Starting preparation at least 12 months before your target sale date gives you time to address issues that would otherwise reduce your price or kill the deal entirely. Key preparation tasks include ensuring your accounts are up to date and professionally produced, documenting processes so the business can run without you, renewing any contracts that are expiring on unfavourable terms, and resolving outstanding disputes or regulatory matters. You should also review your cost base and remove any personal expenses run through the business, since buyers will reverse these adjustments when calculating your adjusted profit.

Before approaching any buyer, you need a realistic view of what your business is worth. Pricing too high deters serious buyers and results in a listing that stagnates; pricing too low leaves money on the table. Use a structured valuation tool to model your asking range using EBITDA multiples, revenue multiples, or asset-based approaches depending on your sector. For most UK SMEs, the EBITDA multiple method is the most relevant starting point. Once you have a range, consider whether your financials are strong enough to support the upper end of that range or whether some preparation work would meaningfully improve your position. For businesses seeking over £500,000, an independent valuation from a business transfer agent or chartered accountant is worth the investment.

The traditional route to finding buyers in the UK is a business transfer agent (BTA) or M&A adviser. Agents bring experience and contacts, but they typically charge a success fee of 3-8% of the sale price, plus upfront marketing fees. The newer route is a business marketplace, which allows you to market your business directly to a large pool of pre-registered buyers at a fraction of the cost. Marketplaces are not a replacement for professional advice in complex deals, but they give you reach and control that a single agent cannot match. Many sellers now use both: a marketplace for broad buyer exposure and an agent or solicitor for deal management and legal work.

Not every enquiry is a serious buyer. Before sharing sensitive financial information, qualify each interested party by checking their financial capacity, acquisition experience, and strategic rationale. A signed non-disclosure agreement (NDA) should be in place before you share detailed accounts, customer lists, or operational information. Once a buyer has access to the full information pack, conversations move to price and structure. Most UK deals involve a mix of cash at completion, deferred consideration paid over time, and an earn-out element tied to the business hitting performance targets in the 12-24 months after sale. Understanding the difference between headline price and actual consideration is critical at this stage.

Due diligence is the buyer's formal process of verifying everything you have represented about the business. Expect requests covering three years of statutory and management accounts, VAT and PAYE records, all customer and supplier contracts, staff contracts and employment records, property leases and asset schedules, intellectual property ownership, and any pending litigation or regulatory matters. Good preparation in step one means due diligence moves quickly. Poor preparation means delays, renegotiation, and sometimes deal collapse. Responding promptly and thoroughly to due diligence requests signals professionalism and reduces the risk of buyers using issues as leverage to reduce the price.

Once due diligence is complete and both parties are satisfied, solicitors draft and negotiate the Sale and Purchase Agreement (SPA). The SPA covers the purchase price, deal structure, representations and warranties, indemnities, restrictive covenants, and completion mechanics. This stage typically takes four to eight weeks, depending on deal complexity and how quickly both sides' lawyers can work. You will need a solicitor experienced in business sales - this is not the time to use a general-purpose firm. Completion day involves the formal transfer of shares or assets, payment of the consideration, and handover of all business materials. Post-completion, you may be required to assist with transition for a defined period under a consultancy or employment agreement.
