Sell Your Business: A Guide for UK SME Owners

Selling the company you built is likely the biggest financial decision of your life. This guide explains how an SME sale works in the UK, what drives the price, how long it takes, and when an M&A adviser earns their fee. Deal Ascent advises founders and family owners of UK businesses with enterprise values of roughly £5m to £100m.

1. Is now the right time to sell?

The right moment combines personal readiness, trading momentum, market conditions and buyer appetite in your sector. Buyers pay most for a business that is growing, with a management team that can run it without the owner. Selling after a weak year, or under time pressure, usually costs value. For the current market, see our UK M&A backdrop for Q3 2026; for the personal side, read business succession planning.

2. What is my business worth?

Most UK SMEs are valued as a multiple of EBITDA. The starting point is the multiple paid for comparable companies in your sector, which you can check on our valuation multiples by sector page. Private companies usually trade at a discount to listed peers for size and liquidity, and the figure you bank is equity value: enterprise value less debt, plus surplus cash, adjusted for working capital. Our guide What Is My Business Worth? explains each step, and our valuation tools give an indicative range.

3. How the sale process works

A competitive sale typically runs through six stages. Our M&A sale process page sets out each one in more detail.

1. Exit readiness and preparation. Tidy the figures, contracts and structure before buyers look. Start with a transaction readiness assessment and check your quality of earnings.
2. Valuation and positioning. Set a realistic price range and the story that supports it, using sector multiples and our valuation guide.
3. Teaser and information memorandum. An anonymous teaser and a detailed information memorandum present the business to buyers. See how to draft a teaser and information memorandum.
4. Buyer outreach. Approach trade buyers, private equity and international acquirers; more than half of UK M&A involves foreign buyers. Read more in what we do.
5. Offers, negotiation and heads of terms. Compare offers on price and terms, then agree heads of terms. See valuation and deal structuring trade-offs.
6. Due diligence, SPA and completion. The buyer checks the business, the lawyers negotiate the sale and purchase agreement, and the deal completes. Plan for tax early with our pre-sale tax planning guide.

4. M&A adviser or business broker?

5. Deal structure: what you actually take home

Two offers with the same headline price can leave you with very different amounts. Cash paid at completion is worth more than deferred consideration or an earn-out that depends on future results. Warranties, indemnities and liability caps in the sale agreement decide how much risk you keep after the sale. Read our guide to earn-outs and valuation and deal structuring trade-offs.

6. Tax before you sell

Business Asset Disposal Relief can reduce the tax on your gain, but it has qualifying conditions that must be met well before the sale. Some structures need two years or more to be in place. See our pre-sale tax planning guide, Business Asset Disposal Relief in 2026 and BADR qualifying conditions.

7. Fees

Deal Ascent charges a 100% success fee, with no retainer, monthly or interim fees. The fee is calculated on equity value, the cash you receive, on a sliding scale from 5% up to £5m down to 2% between £25m and £50m. See our fee structure for the full scale.

Frequently asked questions

How do I sell my business in the UK?

Prepare the business and your figures, get a realistic valuation, approach a range of qualified buyers, negotiate heads of terms, then complete due diligence and the sale agreement, ideally with an M&A adviser and a corporate lawyer.

How much can I sell my business for?

Most UK SMEs are valued as a multiple of EBITDA, adjusted for size, growth, margins and customer concentration. What you bank is equity value after debt and deal terms.

How long does it take to sell a business?

Typically 6–9 months from preparation to completion, depending on how ready the business is, the number of buyers involved and the complexity of due diligence.

What does an M&A adviser do for an SME?

Prepares the business, values it, writes the marketing materials, finds and approaches buyers, runs a competitive process, negotiates price and terms, and manages the deal to completion.

Should I use a business broker or an M&A advisor?

Brokers suit smaller businesses sold through listings; M&A advisers suit businesses of roughly £5m+ value that benefit from targeted buyer outreach and negotiation.

How much does an M&A adviser charge?

Many charge a retainer plus a success fee. Deal Ascent charges only a success fee, with no retainer, calculated on the equity value you receive.

Can I sell my business without an adviser?

Yes, but owners selling alone usually face one buyer, less price tension and weaker protection in the sale agreement.
