Business valuation multiples by industry

Valuation multiples are shorthand for price: enterprise value expressed as a number of times a business's annual profit. In the UK, size and earnings quality move that number more than industry alone, and the multiples reported in M&A news come from deals many times larger than a typical business sale - so they're a poor benchmark for most sellers.

A valuation multiple is shorthand for what a business is worth: its price expressed as a number of times its annual profit. In the UK, that number depends far more on a business's size, the quality of its earnings, and how many buyers are competing for it than on its industry label alone. The multiples quoted in M&A news describe a different, much larger population of deals than most UK business sales, so they make a poor benchmark for a typical owner-managed business.

What a valuation multiple is

A multiple prices a business as enterprise value divided by a profit figure - usually EBITDA (earnings before interest, tax, depreciation and amortisation). "This business sold for 4x EBITDA" means the buyer paid four times that profit figure for the whole business, before adjusting for cash held and debt owed.

EBITDA is the most common earnings base for multiples because it strips out financing structure, tax position and depreciation policy, so businesses can be compared on trading performance rather than on how they happen to be funded or how their accountant depreciates equipment.

Two multiples are only comparable if they're built the same way: the same earnings base (historic year, forecast year, or an average of recent years), the same adjustments to that earnings figure, and the same definition of what enterprise value includes (stock, property, cash). A "5x" in a press release and a "5x" quoted for your business can mean different things underneath.

Why the same profit gets a different multiple by industry

Buyers pay more for a pound of profit when they believe it will repeat next year, and less when it looks fragile or one-off. Industry shapes that belief in a few consistent ways.

The gap between sectors shows up in UK mid-market deal data. In the second half of 2025, a survey of UK & Ireland M&A advisers put the average EBITDA multiple across all sectors at 5.4x, with healthcare and pharmaceuticals at the top of the range (7.5x) and agriculture and food nearer the bottom (5.2x). These are averages across advised, professionally normalised deals - a starting reference point, not a quote for any individual business.

Size moves the multiple more than most sellers expect

Industry sets a rough band. Within that band, size does more to move the actual number than sellers usually expect. The same UK & Ireland survey found the average multiple for a business with around £200,000 of normalised EBITDA was 3.3x, against 8.4x for a business at £10 million of EBITDA - a gap of roughly 5x before sector is even considered.

Normalised EBITDAAverage EV/EBITDA multiple, H2 2025
£200,0003.3x
£10,000,0008.4x

Multiples move progressively between these two points rather than jumping in a straight line - the shift from a business that depends entirely on its owner to one with a manager and a team tends to matter more than any single increment of profit. Why size matters this much: a larger business usually has more customers, staff who can run it without the owner, accountant-reviewed or audited accounts, and access to a wider pool of buyers - trade buyers, private equity, and lenders willing to fund a bigger deal. A smaller, owner-run business concentrates more of that risk in one person, one lease and often one or two large customers, and buyers price that concentration in.

The earnings figure matters as much as the multiple

The multiple is only half the sum. What it's applied to matters just as much, and this is where many first-time sellers under- or overstate their own business.

Reported EBITDA, taken straight from the accounts, usually needs adjusting - or "normalising" - before a multiple is applied. Common adjustments include:

In the US, this adjusted figure for small, owner-operated businesses is usually called SDE (Seller's Discretionary Earnings) and is the standard basis quoted on US business-for-sale listings. UK small-business sales don't use the SDE label as consistently; the adjusted figure is more often described as "normalised" or "adjusted" EBITDA, or "maintainable earnings" - but the underlying idea is the same: strip out anything tied to the current owner or a one-off event, so the multiple is applied to what a new owner could reasonably expect to earn. Every adjustment should be one you can evidence with an invoice, contract or bank statement, because a buyer's due diligence will test each one.

Why headline M&A multiples in the news don't apply to most sellers

Multiples reported in trade press - "9x EBITDA", "private equity paying double-digit multiples" - are real, but they describe a different population of deals to most UK business sales.

BDO's Private Company Price Index tracked UK private companies sold to trade buyers at an average of 9.8x historic EBITDA, and to private equity buyers at 12.2x, in the third quarter of 2024 - roughly in line with the FTSE All-Share's own EV/EBITDA multiple of 11.9x at the time. The trade-buyer deals behind that 9.8x figure had an average enterprise value of £14.6 million; the private-equity deals averaged £42.8 million.

Most UK businesses are nowhere near that size. At the start of 2025 there were 5.7 million private sector businesses in the UK, and 5.64 million of them - 99.2% - had fewer than 50 employees. A business at that scale sits much closer to the £200,000-EBITDA end of the size effect described above than to the multi-million-pound deals that generate M&A headlines.

None of this means small businesses sell for nothing - most UK small business sales still complete at a positive multiple of profit. It means a multiple quoted in the news applies to a specific deal and a specific company; it isn't a rate card that transfers across the size range. HMRC's own Shares and Assets Valuation manual, used to value unquoted company shares for Inheritance Tax and Capital Gains Tax, exists precisely because private, unquoted companies aren't priced the way listed companies are - there is no single market price to read off, and each valuation is worked out on its own facts.

What actually moves your multiple

Within your sector and size band, the specific factors that push a multiple up or down are largely the same, whatever you sell.

Improving these before a sale usually does more for the final price than waiting for sector sentiment to shift, since they're the factors a buyer's own due diligence will focus on regardless of the headline multiple in the news that week.
