How to value your small business in the UK

The main ways to value a UK small business – earnings multiples, assets and discounted cash flow – what affects the price, and how to prepare for a sale.

Updated: 2026-10-24 · 7 min read

In short: Most small UK businesses are valued using a multiple of their maintainable profits, an asset-based valuation, or a cash flow forecast. The right method depends on the type of business. A valuation is an estimate, not a price: the final figure depends on buyers, risk and how well prepared your records are, so use a qualified adviser for a sale or tax matter.

You might need a valuation to sell your business, bring in an investor, buy out a partner, plan for retirement or deal with a tax or legal matter. There is no single correct figure. Different methods give different answers, and the real value is what a willing buyer pays.

Start with clean numbers

Every method relies on reliable financial information. Before valuing, gather:

  • at least three years of accounts, if you have them
  • up-to-date management accounts
  • details of assets, debts and stock
  • key contracts with customers, suppliers and staff
  • any leases, loans and guarantees

If your records are messy, a buyer will see more risk and offer less.

Method 1: earnings multiple

This is the most common approach for profitable small businesses.

  1. Work out maintainable profit. Start with your profit before tax and adjust for one-off or personal items. For example, add back a one-off legal bill, and adjust the owner's salary to a market rate for someone doing the job.
  2. Apply a multiple. Multiply the adjusted profit by a figure that reflects risk and growth prospects.

There is no fixed multiple. It depends on your sector, size, growth, how dependent the business is on you, and the wider market. A specialist adviser or business broker can tell you what comparable businesses have sold for.

Some valuers use EBITDA (earnings before interest, tax, depreciation and amortisation) as the profit figure. Make sure you know which measure is being used when comparing figures.

Method 2: asset-based valuation

This adds up what the business owns and subtracts what it owes.

  • Net book value uses figures from your balance sheet.
  • Adjusted net assets revalues items, such as property or equipment, at their current market value.

It suits asset-heavy businesses, such as property or manufacturing, or businesses that are not very profitable. It often undervalues service businesses, whose value lies in clients and people rather than equipment.

Method 3: discounted cash flow (DCF)

DCF estimates future cash the business will generate and converts it into today's value using a discount rate that reflects risk. It is useful for growing businesses but is only as reliable as the forecasts behind it, so buyers will test the assumptions closely.

Other approaches

  • Revenue multiples are sometimes used for fast-growing or subscription businesses with little profit yet.
  • Comparable sales look at what similar businesses sold for.
  • Entry cost asks what it would cost to build an equivalent business from scratch.

What pushes value up

  • steady, growing profits
  • a wide spread of customers rather than one or two big clients
  • recurring or contracted income
  • a business that runs well without the owner
  • strong brand, website and reputation
  • good systems, records and documented processes
  • protected intellectual property, such as trade marks

What pulls value down

  • reliance on the owner's personal relationships
  • unclear or messy accounts
  • overdue filings or tax issues
  • disputes, legal claims or unclear ownership of shares
  • key staff who could leave

Valuing shares in a limited company

If the business is a limited company, a buyer may purchase the shares or just the assets. A share sale transfers the whole company, including its history and liabilities, so buyers usually carry out detailed due diligence. A minority shareholding is often valued at a discount because it carries less control.

Tax and legal points

Selling a business or shares can have Capital Gains Tax consequences, and some reliefs may apply depending on your circumstances. HMRC may also need a formal valuation in some situations, such as gifts of shares or employee share schemes. These rules are complex, so speak to an accountant or tax adviser before you agree a deal.

Preparing for a sale

  1. Get your accounts and Companies House filings up to date.
  2. Tidy up contracts, leases and share records.
  3. Reduce dependence on yourself by delegating and documenting processes.
  4. Get an independent valuation.
  5. Appoint a solicitor experienced in business sales.
