How to Value a Business in the UK: A Practical Guide for Buyers and Sellers

When people first look at how to value a business in the UK, they almost always start with the same assumption: the asking price is the valuation. It isn't.

The asking price is what the seller wants. The valuation is what the business is actually worth — derived from its earnings, assets, risk profile, and what comparable businesses have sold for. These two numbers can be very far apart, and confusing them is one of the most expensive mistakes a first-time buyer makes.

Valuation confuses sellers too. Some believe their business is worth a round multiple of revenue. Others peg their price to what they "need" for retirement. Neither is how buyers assess value, and arriving at a number that doesn't match how the market thinks will mean either no sale or a long, painful process of adjustment.

This guide walks through the main valuation methods used in UK business sales, how to apply them, and what factors push a price up or down. Whether you're browsing businesses for sale on NewOwner or preparing your own exit, understanding valuation is the skill that will save or cost you the most money.

For any business with a trading history and meaningful profit, the EBITDA multiple is the dominant valuation method in UK M&A. You need to understand it. It's how buyers, sellers, and advisers all talk about price.

What EBITDA actually measures

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortisation. It strips out financing decisions, tax structures, and accounting treatment to expose the underlying operating performance of the business. It measures what the business actually generates each year, once you strip out how it's financed and how the accountant treats depreciation.

For owner-managed SMEs, this figure is almost always normalised first — adjusted to remove personal expenses, above-market owner salaries, and one-off costs that wouldn't exist under new ownership. If you want to understand that process in depth, the normalised EBITDA guide for UK business buyers and sellers covers every common adjustment and how buyers assess them.

How the multiple works

The formula:

Enterprise value = Normalised EBITDA x Multiple

So if a business generates £400,000 in normalised EBITDA and the applicable multiple is 4x, the enterprise value is £1.6 million. The purchase price for the shares or assets is then derived from enterprise value, adjusted for cash, debt, and working capital at completion.

What determines the multiple

The multiple isn't a fixed number — it reflects how buyers assess the risk and growth potential of that specific business. The main factors:

• Sector. Software businesses attract 8–12x; manufacturing might see 4–6x
• Size. Larger businesses trade at higher multiples because they carry lower risk
• Revenue quality. Recurring income gets a premium over project-based work
• Growth trajectory. Consistent 15%+ annual growth lifts the multiple
• Owner dependence. A business that can't function without the current owner gets discounted
• Customer concentration. If one client accounts for more than 25% of revenue, buyers get nervous

For small UK businesses with EBITDA below £250,000, expect multiples in the 2.5–4x range. Mid-market businesses with EBITDA of £500,000–£2 million typically see 4–6x. Above that, multiples climb, especially in tech and healthcare.

Knowing your industry's typical multiple range matters more than most first-time buyers realise. A 4x EBITDA offer on a SaaS business is deeply undervalued. A 4x offer on a newsagent is generous. The sector changes everything.

The table below reflects typical EBITDA multiples being paid in UK business sales. These are ranges, not guarantees — good businesses sell at the top of the range, average ones sit in the middle or below.

Sector	Typical EBITDA multiple	Key value drivers
Software / SaaS	8x – 14x	ARR, churn rate, net revenue retention
Technology services	6x – 9x	Contracted revenue, IP, technical talent
Business services	5x – 7x	Client retention, contracted work, scalability
Healthcare / dental	6x – 10x	CQC compliance, patient list, recurring income
Recruitment	4x – 6x	Perm fees vs contract mix, sector specialism
Manufacturing	4x – 6x	Equipment condition, customer concentration
Construction / trades	3x – 5x	Pipeline, key-person risk, certification
Hospitality / food & drink	3x – 5x	Lease terms, footfall, brand, reviews
Retail (physical)	2x – 4x	Lease length, online presence, margin
E-commerce	3x – 6x	Traffic quality, supplier terms, margin

These multiples apply to normalised EBITDA, not gross profit or revenue. Buyers who've looked at a few deals will immediately ask for the normalised EBITDA figure — presenting revenue multiples or turnover-based valuations signals you haven't done this before.

For a professional framework on how chartered accountants approach business valuation evidence, the ICAEW's guidance on business valuations is a useful reference point, especially on what makes a valuation defensible.

Not every business earns its value through profit. For some, the assets are the value.

Asset-based valuation calculates the net asset value (NAV) of a business — the total of its tangible assets minus its liabilities. It's the method most relevant for:

• Businesses with significant physical assets (property, plant, machinery, vehicles, stock)
• Companies with low or negative profitability where EBITDA multiples produce a depressed result
• Holding companies where the assets are the point
• Situations where a buyer is acquiring specific assets rather than the company itself

How to calculate it

Start with the balance sheet. Take the value of fixed assets, stock, debtors, and cash. Subtract liabilities: creditors, loans, lease obligations, tax payable. What remains is the net asset value.

Book value and market value rarely match, though. Machinery on the balance sheet at £80,000 after depreciation might fetch £140,000 at auction — or £30,000. Property often carries significant uplift versus historic cost. So an asset-based valuation typically requires independent appraisals, not just the accounts.

Its limits

The caveat: for most profitable, going-concern businesses, asset-based valuation produces a floor, not a ceiling. If a profitable business is worth 5x EBITDA on an earnings basis but only 1.8x on an asset basis, no rational seller accepts the lower number. The earnings method wins.

Asset-based valuation takes over when earnings are minimal (a business that breaks even doesn't give you much from EBITDA multiples) or when the buyer is specifically acquiring assets rather than an ongoing enterprise. Liquidation value (what you'd get if you wound the business up tomorrow and sold everything) is the most conservative version of this approach, and it's typically a buyer's backstop when things go wrong.

The comparable sales method (often just called "comps") values a business by looking at what similar businesses have sold for. It's standard practice in residential property. In UK business sales, it's less dominant but useful as a cross-check.

The idea is simple: if three businesses in the same sector, with similar turnover and profit margins, sold at 4–5x EBITDA in the past 18 months, that range is evidence of market value for a fourth comparable business.

Where to find comparable data

This is where it gets harder for private buyers. Unlike listed company transactions, private UK business sales aren't disclosed publicly by default. The main sources of comparable transaction data:

• Corporate finance advisers. Firms like BDO and Grant Thornton maintain proprietary databases of completed deals with transaction multiples. Their research on UK mid-market M&A transactions is widely cited.
• Sector-specific brokers. BCMS and similar SME brokers accumulate deal data from their own completed transactions.
• ICAEW and professional bodies. Publish valuation guidance with sector reference ranges.
• Companies House. For asset deals or share sales where a statutory filing reveals consideration paid.

Using comps intelligently

Comparables are a sense-check, not a definitive answer. Every business is different. A 20-year-old plumbing company with three vans and no digital presence isn't comparable to a plumbing business with a subscription maintenance offering and 40% repeat revenue, even if they look similar in size.

The strongest valuations use all three methods and check them against each other. If EBITDA multiples, asset values, and comps all point at roughly the same number, you're probably in the right place. If they diverge sharply, the gap itself tells you something worth understanding.

You can also observe current market pricing directly by browsing investment opportunities on NewOwner — what sellers are asking, in what sectors, at what implied multiples.

Two businesses can have identical EBITDA and still sell at dramatically different prices. The difference comes down to qualitative factors that experienced buyers — particularly private equity and trade buyers — have learned to price in.

The factors that add value

Recurring revenue. A business where 70% of income is contracted or subscription-based is far less risky than one that has to win every pound from scratch. Recurring revenue typically adds 1–2x to the multiple.

Management depth. If the business runs for six months without the current owner, that's worth money. If it can't survive a fortnight, that's a problem.

Customer diversification. No single customer should account for more than 20–25% of revenue. Above that, buyers apply a concentration discount, sometimes a steep one.

Clean accounts. Accounts that match the management information and don't throw up surprises. Where the numbers don't add up, buyers get nervous, and nervous buyers don't offer full price.

The factors that take value away

Key-person risk kills more SME deals than anything else. If the business's relationships, knowledge, or reputation live entirely with the current owner, buyers price in the risk of losing those when the owner exits.

Revenue decline. Even a modest downward trend in the last 12–18 months is deeply concerning. A business earning £500,000 EBITDA two years ago and £380,000 today isn't worth 5x £380,000 in most buyers' minds — they're pricing where it heads next, not where it's been.

Poor financial records. Incomplete management accounts, cash transactions not properly recorded, or accounts that differ from the information memorandum are deal-breakers for most professional buyers.

For buyers trying to assess a specific deal, the business buyer starter kit covers the due diligence steps to verify these qualitative factors before making an offer. And once a deal completes, understanding how to transition into business ownership — handling staff, customers, and processes in the first 90 days, makes a real difference to how the first year plays out.

It's worth being direct about this, because it comes up in nearly every conversation with first-time sellers.

An asking price is a negotiating position. It reflects what the seller wants, which might be based on what they need for retirement, what a friend got for a vaguely similar business, or a multiple someone mentioned at a networking event. None of that is valuation.

Valuation is what the market will pay, derived from earnings, assets, comparables, and risk. Those two things can differ by 30%, 50%, or more.

Worth noting: In the UK SME market, it's common for businesses to sit unsold for 12–24 months because they're priced above what buyers will pay. Getting an independent valuation before setting an asking price — not after — saves a great deal of time and frustration.

Common seller pricing mistakes

Revenue multiples. "We turn over £2 million, so we're worth at least £1 million." Revenue isn't the metric buyers use. A £2 million turnover business generating £100,000 EBITDA is worth far less than one generating £500,000 on the same revenue.

Ignoring normalisation. Sellers who add back personal expenses but don't deduct a replacement MD salary, or who add back "one-off" costs that recur every year — end up with an inflated EBITDA that falls apart in due diligence.

The retirement number fallacy. Needing £800,000 for retirement has nothing to do with what your business is worth. Market value is determined by buyers, not by seller needs.

Overweighting strategic value to one specific buyer. Yes, your business might be worth more to one particular acquirer who could achieve synergies. But valuing a business as if every buyer is that strategic acquirer doesn't work in practice — most buyers aren't paying for synergies they have to create.

Pricing based on past performance. A business that earned £600,000 EBITDA three years ago but earns £350,000 today will be valued on current and projected performance, not historic peak. Buyers pay for future cash flows.

There are several routes to getting a valuation, and they vary considerably in rigour and cost.

Online valuation tools

Free calculators give you a rough sense of range in 30 seconds. They're useful for a quick sanity check, not for setting an asking price or making an offer. They typically use simple revenue or profit multiples without accounting for sector, quality, or current market conditions.

Business brokers

Most brokers will provide a free indicative valuation as part of their pitch for the mandate. The caveat: some inflate valuations to win instructions, then spend months managing expectations downward. Ask how many of their listings sell at the original asking price, and in what timeframe.

Corporate finance advisers

For businesses above roughly £500,000 EBITDA, a corporate finance adviser's formal valuation report is worth commissioning. These draw on transaction databases, sector expertise, and financial modelling. They cost money — typically £5,000–£15,000 for an SME — but for a transaction worth several million pounds, that's not a meaningful number.

Accountants

Chartered accountants with M&A experience can prepare defensible valuations, particularly for probate, shareholder disputes, or HMRC purposes. They're also the right people to commission a quality of earnings report on behalf of the buyer.

Doing it yourself

If you understand the methods, you can produce a reasonable working valuation. Take three years of normalised EBITDA, apply the appropriate sector multiple, adjust for qualitative factors, and cross-check against asset values and any available comparables. It won't be definitive, but it tells you whether you're in the right ballpark — and it gives you a basis for challenging the seller's number during negotiations.

Buyers and sellers use the same valuation methods but with completely different objectives. Knowing how the other side thinks helps.

If you're a buyer

Your job is to stress-test every assumption in the seller's valuation. Is the normalised EBITDA genuinely clean? Does the multiple reflect the actual risk profile of this specific business? What happens if the top customer leaves, or if the current owner's relationships don't transfer?

A buyer's valuation is forward-looking. You're not paying for what the business earned last year — you're paying for what you believe it will earn under your ownership. If you can improve it, you might justify a higher price. If the seller's projections are optimistic, you need to price that risk in.

Paying a multiple that implies significant growth you're not confident you can achieve is how buyers end up regretting acquisitions. The number has to make sense on current earnings, not hypothetical future performance.

If you're a seller

Your job is to present the business in a way buyers can trust. That means clean financial records, conservative EBITDA adjustments, and a credible narrative about why the business is worth its price. Sellers who try to justify high prices with aggressive add-backs or optimistic projections often end up with buyers who chip the price during due diligence — or walk away entirely.

Also think carefully about deal structure. A higher headline price with deferred consideration (an earnout) isn't the same as cash at completion. Understand what you're actually receiving before agreeing to a price. The guide to making an offer and negotiating a business purchase walks through LOIs, earn-outs, and closing tactics in detail.

Both buyers and sellers benefit from understanding how institutional buyers approach deals — the guide to private equity trends in the UK for 2026 covers how PE firms are thinking about pricing right now, which sets the benchmark in many sectors.

This works for any UK business, whether you're on the buying or selling side.

Steps 1–3: From normalised EBITDA to enterprise value

Step 1: Calculate normalised EBITDA for each of the last three years. Start with statutory accounts. Remove interest, tax, depreciation, and amortisation. Then make defensible adjustments for owner-specific costs. Document every adjustment with supporting evidence: invoices, contracts, payslips.

Step 2: Identify the right sector multiple. Use the table earlier in this guide as a starting point. Adjust up or down based on the quality factors that apply to this specific business: recurring revenue, customer concentration, growth trend, owner dependence.

Step 3: Apply the multiple to get enterprise value. Use the most recent year's normalised EBITDA as the primary input, but check it against the three-year average. If there's a clear trend (growth or decline), weight your view accordingly.

Steps 4–6: Cross-check, compare, and set a range

Step 4: Cross-check with asset-based valuation. Calculate the net asset value from the balance sheet, adjusting assets to market value where relevant. If enterprise value significantly exceeds NAV, the premium represents goodwill — buyer confidence in future earnings. If NAV approaches enterprise value, scrutinise the earnings assumptions.

Step 5: Find comparable transactions. Talk to a corporate finance adviser or broker for their market data. Look at asking prices on active listings in the same sector. Adjust for size and quality differences between those businesses and yours.

Step 6: Arrive at a range, not a single number. A good valuation produces a range, say £800,000 to £1.1 million, with a central case and the key variables that would push you toward each end. Buyers negotiate from the bottom. Sellers should price toward the middle.

For buyers, completing thorough financial and commercial due diligence before exchanging contracts is as important as the valuation itself. The guide to analysing a business before buying covers the due diligence steps that protect you after you've agreed on price.
