Ask ten business owners what their company is worth, and you’ll get ten confident answers – most of them wrong.
It’s one of the strangest blind spots in business ownership. You can probably tell me your turnover to the pound, your best client’s payment terms, and exactly how much your biggest supplier owes you. But ask what a buyer would actually pay for the whole business tomorrow, and the answer is usually a guess dressed up as a fact – often based on something a friend’s business sold for, a multiple someone mentioned at a golf day, or simply “what I need it to be worth” to fund retirement.
That guess matters more than most owners realise. It feeds your succession plan, your exit strategy, your Business Relief position, and – if you have co-owners – the cross-option agreement that’s supposed to protect everyone’s family if one of you dies. Get the number wrong and every plan built on top of it wobbles.
Valuation is not the same as price
The first confusion to clear up: valuation and price are not the same thing, and conflating them is where most owners go wrong.
Valuation is an estimate – a considered, evidence-based view of what the business is likely worth, based on its earnings, assets, risks and market comparables. It’s what an accountant, a corporate finance adviser, or HMRC’s valuation office would produce if asked.
Price is what someone actually agrees to pay, in a specific negotiation, at a specific moment, in specific market conditions. Price is shaped by things valuation can’t fully capture: how badly the buyer wants your customer list, whether there’s a competing bidder, how motivated you are to sell, and plain old negotiating skill on the day.
A valuation tells you the sensible starting point for a conversation. Price is what happens after that conversation. Owners who confuse the two tend to anchor on an optimistic valuation, treat it as the price, and then feel blindsided when real offers land 30-40% lower.
The multiple of what, exactly?
Most private company valuations are built around a multiple of adjusted EBITDA – earnings before interest, tax, depreciation and amortisation, adjusted to strip out one-off costs and add back anything unusual. The multiple a buyer is willing to pay depends heavily on size, sector, and how the business is run.
As a rough guide, and these are illustrative ranges rather than a valuation – every deal is different:
- Small, owner-run businesses turning over under roughly £1 million often trade at somewhere in the region of 2-4 times adjusted EBITDA, because the buyer is effectively buying a job as much as a business.
- Established SMEs with a management layer beneath the owner, recurring revenue and a track record tend to sit higher, often in the 4-6 times range.
- Larger, well-systemised businesses with diversified customers, strong recurring revenue and a genuine leadership team can command multiples well above that, particularly in sectors buyers see as resilient or high-growth.
Sector matters too. Businesses with contracted, recurring income – software, managed services, some professional practices – tend to attract richer multiples than businesses with lumpy, project-based or highly cyclical revenue, even at similar size. A construction firm and a subscription-based service business with identical turnover and profit can be worth very different amounts, because buyers are really pricing certainty of future income, not last year’s numbers.
The owner dependency discount
Here’s where the guesswork usually falls apart: adjusted EBITDA is meant to reflect what the business would earn under new ownership, not what it earns with you working 60-hour weeks for a salary you set yourself.
Many owner-managers pay themselves below a fair market rate for the role they do, because the profit simply stays in the business either way. When a valuer “normalises” your salary – substituting in what it would genuinely cost to hire a managing director to do your job – reported profit often falls, sometimes sharply. A business that looks like it makes £300,000 a year might really be making £220,000 once someone is paid properly to replace you.
Then comes the harder question buyers ask: if you walked away tomorrow, would the business keep running? If every key client relationship, every supplier deal, and every important decision runs through you personally, a buyer isn’t just buying lower future profit – they’re pricing in genuine risk that the business falls over without you. That shows up as a lower multiple, an earn-out structure that keeps you tied in for years, or both.
Concentration risk and weak systems – the two biggest discounts
Beyond owner dependency, two other factors routinely knock value off an otherwise healthy business.
Customer or supplier concentration. If one client accounts for a large share of revenue, or you rely on a single supplier with no alternative, a buyer sees fragility, not strength – however profitable things look today. Lose that one relationship and the numbers collapse. Buyers price that risk in with a lower multiple, and it’s one of the most common reasons a business sells for less than the owner expected.
Weak systems and documentation. Businesses run from the owner’s head – undocumented processes, informal contracts, no management accounts beyond what the bookkeeper produces at year end – are harder to hand over and harder to trust. Buyers pay a premium for businesses that could be run by someone else next week, and apply a discount to businesses that couldn’t.
The uncomfortable truth is that most of these discounts are entirely within an owner’s control, given enough time. A business with three years’ notice to diversify its customer base, document its processes and build a genuine management layer can transform its valuation. A business valued the week before sale usually can’t fix any of it.
Why an unrealistic valuation wrecks succession and estate planning
This is where valuation stops being an academic exercise and starts affecting real families.
Many succession plans are built around a number the owner picked, not a number the market would pay. If you’re planning to sell to your children, fund your retirement from the proceeds, or split value fairly between a child in the business and a child outside it, an inflated valuation makes all of that maths wrong. Children who buy the business at a fanciful price start their ownership under an unsustainable debt burden. Retirement plans built on an optimistic sale price leave a gap that has to be filled from somewhere else.
It matters for estate planning too. If you die holding shares valued (in your own mind, or in outdated paperwork) at a figure well above what the business would actually fetch, your executors and family are left trying to unpick the gap – sometimes while also dealing with inheritance tax on a value that was never realistic in the first place.
How valuation feeds Business Relief and cross-option agreements
Two of the most important protections available to business owners both depend directly on getting the valuation right, not on wishful thinking.
Business Relief can reduce or remove inheritance tax on qualifying business assets, but from April 2026 it sits within a combined £2.5 million cap shared with Agricultural Relief, with relief above that cap given at a reduced rate rather than in full. Whether your estate sits comfortably under that cap, brushes against it, or sails well past it depends entirely on an accurate, current valuation of the business – not a figure from three years ago, and not the number you’d like it to be. Owners who assume their estate is fully sheltered because “the business qualifies for relief” are often surprised to find a realistic valuation pushes them over the cap.
Cross-option agreements – the arrangement between co-owners that lets survivors buy a deceased partner’s shares, usually funded by life insurance – only work if the valuation mechanism behind them is realistic and kept up to date. If the agreed valuation formula understates the business, the surviving family gets short-changed for their share. If it overstates the business, the insurance cover in place won’t stretch to fund the buyout, leaving the surviving owners scrambling for finance at the worst possible time, or the deceased’s family stuck as reluctant co-owners of a business they have no interest in running.
A valuation that’s reviewed every year or two, alongside insurance cover that’s checked against it, is one of the few pieces of planning that genuinely protects both the business and the families depending on it.
Get a number you can actually rely on
Guessing your business’s worth might feel harmless until it’s the number your retirement, your children’s inheritance, or your business partner’s family is relying on. If you haven’t had your business properly valued in the last couple of years – or your succession, Business Relief position and cross-option agreements were built on a figure nobody has checked – it’s worth putting that right before it’s forced on your family at the worst possible moment.
