How Long Does It Take to Sell a Business?

For most owner-managed UK businesses, six to twelve months from the start of preparation to money in the bank is a reasonable planning assumption. It is not a promise. Some transactions complete inside four months; others run well beyond a year, usually for reasons that were visible at the outset. What matters more than the headline figure is understanding which stages you control and which you do not.

The timetable, stage by stage

The ranges below describe what we typically see on lower mid-market UK transactions. They overlap in practice, and they vary with the size and complexity of the business.

• Preparation. Usually one to three months, occasionally longer where management information needs rebuilding or a structural issue has to be resolved first. This is the work that determines how the rest of the process goes.
• Buyer research. Two to four weeks, running alongside preparation. Building a considered list of credible acquirers, rather than a list of everyone in the sector, takes real time and saves far more later.
• Approaches. Two to six weeks. Buyers are approached selectively and anonymously. Corporate development teams are frequently slow to respond, and the first reply is rarely the decision.
• NDA and information release. Two to four weeks. Confidentiality agreements are signed and the information memorandum is released to parties who have demonstrated genuine interest.
• Management meetings. Three to six weeks. Interested buyers meet the owner and, in most cases, a small number of senior people. Diary coordination alone often costs a fortnight.
• Indicative offers. Two to four weeks after meetings. Offers are non-binding and arrive in inconsistent formats, which is why they need to be compared on structure as well as headline price.
• Heads of terms. Two to four weeks. The commercial shape of the deal is agreed and usually an exclusivity period begins.
• Due diligence. Six to twelve weeks, and the single most variable stage. Financial, legal and commercial workstreams run in parallel, and each produces follow-up questions.
• Legal documentation. Six to ten weeks, largely overlapping due diligence. The share purchase agreement, disclosure letter and any ancillary documents are negotiated between solicitors.
• Completion. Signature, funds flow and the agreed post-completion mechanics, including any completion accounts process that follows in the weeks afterwards.

The full sell-side process sets out what happens at each of those stages and who does what.

What makes a sale faster

• Clean, reconciled management accounts that agree to the statutory accounts without explanation.
• A data room assembled before launch, rather than compiled question by question during diligence.
• A single decision-maker, or shareholders who have already agreed their objectives and their price expectations.
• A buyer who has done this before and has funding in place rather than subject to approval.
• Prompt responses. A seller who answers within a day keeps momentum; a week's delay compounds through every workstream.

What makes a sale slower

• Reconstructing financial information after the process has already started.
• A first-time or acquisitive-but-unstructured buyer whose internal approvals are unpredictable.
• Issues discovered late, such as an unassigned property lease, informal supplier terms or a customer contract with a change-of-control clause.
• Multiple shareholders who have not aligned on price, structure or timing before offers arrive.
• Funding that depends on a lender, which adds its own diligence and credit process.
• Seasonality, both in the business's own trading cycle and in the calendar.

Common misunderstandings

The first is that finding a buyer is the long part. It rarely is. Interest usually emerges within the first couple of months; the months that follow are spent verifying the business and documenting the deal. The second is that a fast process is a good one. Speed achieved by accepting the first offer, with no competing party, almost always costs more in price and terms than it saves in time. The third is that preparation delays a sale. Time spent before going to market is the most reliable way to shorten the period a buyer can see, and to reduce the risk of renegotiation later.

What to do next

If you have a date in mind, whether a retirement, a shareholder deadline or a family reason, work backwards from it and allow for slippage. If you want to be in a position to transact in twelve months, the preparation work should be starting now. Our guide to selling your business covers valuation, buyers and the process in one place.
