Ask three advisers what your business valuation should be and you will probably get three different answers. All three could be defensible. A business valuation is not a single figure waiting to be uncovered. It is a range. Four things shape it: who is asking, why they want to know, what else they could compare you to, and how much risk they see in your numbers.
That matters whether you are weighing up a sale in five years or bringing in an investor next quarter. It matters just as much when settling a shareholder dispute, or simply trying to understand what you have built. This guide covers how business valuation works for UK small and medium-sized businesses in 2026. It explains the methods behind the numbers, and where to get a credible figure without overpaying for one.
There is no single business valuation, only a range
The same business can be worth different amounts to different buyers at the same moment. A trade competitor might pay a premium for your customer list because it removes a rival. A private equity buyer might value your recurring contracts more than your brand. A family member taking over might simply pay what they can afford. That often means a gradual buyout rather than a lump sum.
This is why it helps to treat a business valuation as a range, not a number. Four things decide where you land: the buyer, their motivation, their alternatives, and the risk they see in your numbers.
The gap between what owners expect and what the market actually pays is wider than most founders assume. The Dealsuite UK and Ireland M&A Monitor, published in August 2026, puts numbers on this gap. In 49 per cent of sale processes, seller price expectations were too high relative to what buyers were willing to pay. Nearly half of owners, in other words, start from a business valuation that the market simply will not support. Understanding the methods behind the multiples is the best defence against that gap.
The main valuation methods, in plain English
Most valuation approaches for UK businesses fall into four categories. Which one applies depends on your size, your sector, and how much the business relies on your own labour.
Earnings multiples on EBITDA
This is the standard approach for established SMEs with proper management accounts. EBITDA means earnings before interest, tax, depreciation and amortisation, essentially your trading profit before financing and accounting adjustments. You multiply that figure by a sector-appropriate multiple to reach an enterprise value.
As a general guide, basic service businesses facing high competition tend to sit around 2 to 3 times EBITDA. Established businesses with a steady, diversified customer base typically command 4 to 6 times. Businesses with genuine competitive advantages, strong brands, proprietary technology, or locked-in contracts can reach 7 times or higher.
Seller’s discretionary earnings, for owner-run businesses
For sole traders and very hands-on limited company directors, EBITDA alone often understates real earning power. Your own salary, benefits, and personal expenses all run through the accounts. Seller’s discretionary earnings, or SDE, adds these back to show what a new owner-operator could realistically take home.
SDE is the standard basis for valuing micro businesses: cafés, salons, trades, and small e-commerce shops. Multiples here are lower than EBITDA multiples, typically 1.5 to 3 times. That is because the buyer is usually buying themselves a job, not a management team.
Asset-based valuation
For asset-heavy businesses, the trading profit may understate the real worth. Think engineering firms, haulage companies, or anyone sitting on valuable premises, plant, or stock. An asset-based valuation totals the net value of tangible and intangible assets, minus liabilities. This approach matters most when a business is loss-making or marginal. Its equipment, property, or stock may be worth more than the trading multiple would suggest.
Discounted cash flow, in outline
Larger or high-growth businesses sometimes use discounted cash flow. This method projects future cash flows and discounts them back to today’s value using a chosen rate of return. It is the most theoretically rigorous method, but it is also the most sensitive to assumptions about future growth. For most owner-managed UK businesses, it is enough to know this method exists. Earnings multiples and SDE will do the practical work.
The size discount: why smaller businesses sell for less
UK deal data shows a consistent pattern: smaller businesses attract lower multiples than larger ones, even in the same sector. This is often called the size discount, and it is worth understanding before you anchor on a figure.
The MarktoMarket H1 2026 UK M&A Valuation Indices put numbers on it. In the first half of 2026, businesses selling for under £2.5 million changed hands at a median of 3.7 times EBITDA. Across the wider market, defined as all UK deals under £250 million in enterprise value, the median was 6.0 times. That is a substantial gap for what might look, on paper, like a similar business.
The Dealsuite UK and Ireland M&A Monitor from August 2026 shows the same pattern in finer detail. Average multiples rise from 3.6 times at £200,000 of EBITDA to 8.2 times at £10 million of EBITDA. Multiples do not scale in a straight line. They climb as businesses get bigger, more resilient, and less dependent on any one person.
Market conditions shift year to year as well. The UK200Group SME Valuation Index 2025 recorded a decline in the median EBITDA multiple for UK SME deals. The figure fell from 5.5 times in 2024 to 4.5 times in 2025. That is a reminder that valuation is not just about your own numbers. It also reflects borrowing costs, buyer confidence, and how much competing deal flow is in the market at the time.
Why does size matter so much? Buyers usually see smaller businesses as riskier. They often depend on a handful of customers, run with thin management teams, and have little financial cushion. The pool of buyers able to finance a smaller deal is also narrower. All of that feeds into a lower multiple.
What pushes your multiple up or down
Within any sector range, two businesses with identical turnover can attract very different multiples. A handful of factors consistently move the number.
- Recurring revenue. Subscriptions, retainers, and long-term contracts make future income predictable. Buyers reward that with a higher multiple than one-off project work.
- Customer concentration. If one client accounts for 40 per cent of revenue, buyers see concentrated risk. They will discount the multiple accordingly, however strong the relationship feels to you.
- Transferability. Could the business run without you for a month? Buyers discount heavily for founder dependency because the value walks out of the door with you. Documented processes and a trusted second-in-command both push the multiple up.
- Sector. Some sectors simply command more than others, regardless of how well-run an individual business is.
Indicative sector ranges commonly quoted by UK brokers and business transfer agents in 2026 give a useful anchor. Treat them as rules of thumb rather than figures from a single published dataset:
- Retail: 2 to 3.5 times EBITDA
- Garages and automotive: 2.5 to 4 times EBITDA
- Construction and trades: 3 to 5 times EBITDA
- Hospitality: 2.5 to 4.5 times EBITDA
- Consultancies and agencies: 3.5 to 5.5 times EBITDA
- Manufacturing: 4 to 6 times EBITDA
- Care homes: 5 to 9 times EBITDA
- Software and technology: 6 to 12 times EBITDA, sometimes more
For owner-run micro businesses valued on seller’s discretionary earnings, the multiples are lower. Cafés and takeaways typically sit at 1.5 to 3 times SDE, hair and beauty at 1 to 2.5 times, and e-commerce at 2.5 to 5 times.
Two worked examples of business valuation in practice
Numbers make this concrete. Here are two scenarios that show how the methods and multiples interact.
Example one: a hair and beauty salon. The owner works full-time in the business alongside one part-time stylist. After adding back the owner’s salary, pension contributions, and personal use of the business car, SDE comes to £45,000. Hair and beauty businesses typically sell at 1 to 2.5 times SDE. That gives a valuation range of £45,000 to £112,500. Where you land depends on lease length, client loyalty, and whether the stylist would stay on under new ownership.
Example two: a marketing consultancy. This business has EBITDA of £300,000. Most of it comes from 12-month retainer contracts spread across 15 clients. None represents more than 12 per cent of revenue. Consultancies and agencies typically trade at 3.5 to 5.5 times EBITDA. Strong recurring revenue and low customer concentration could push a buyer towards the upper end, say 4.5 times. That gives a valuation of around £1.35 million, within a realistic range of £1.05 million to £1.65 million. This sits comfortably under the £2.5 million threshold. At that size, the MarktoMarket data shows median multiples closer to 3.7 times. So the owner would be wise to treat 4.5 times as an ambitious but achievable target, not a guaranteed outcome.
Getting a business valuation, even when you are not selling
You have three broad routes to a number, each suited to a different purpose.
- Online calculators. Free, quick, and useful for a rough first estimate. They rely on generic multiples, though, and cannot account for your specific customer base, contracts, or sector nuances.
- Broker valuations. Many business brokers offer free indicative valuations as part of pitching for your instruction. These can be useful as a sense check. Treat them with some caution, though, since a broker benefits from a higher estimate that wins your business.
- Accountant or corporate finance valuations. This usually costs a few hundred to a few thousand pounds, depending on complexity. It draws on your actual accounts, so it is far more defensible if a buyer, investor, or HMRC challenges it.
You do not need to be selling to benefit from a proper business valuation. Commission one before raising investment, because investors will want a pre-money figure to calculate what equity they receive. For women founders this carries extra weight: all-women founding teams still receive only a small fraction of UK equity investment, so walking into that negotiation with a defensible figure is leverage, not vanity. A valuation also matters for shareholder or partnership disputes, and for divorce or probate settlements. The same applies to succession planning when a family member takes over, and to employee share schemes such as Enterprise Management Incentive (EMI) options. HMRC has its own process for shares and asset valuations for tax purposes, and it follows its own rules. Get it right from the start rather than retrofitting later.
A valuation done every year or two, even informally, gives you something more useful than a sale price. It tells you whether the business is actually becoming more valuable, or just busier.
If you are building towards a future business valuation, understanding your profit and loss statement properly is the first step. Every method above starts with accurate numbers. And if you are considering outside investment rather than a sale, look at grants for women in business and other ways to raise cash without asking the bank before you commit to giving away equity at any particular price.
