A valuation carried out before a sale estimates what a business might fetch in an open market sale at one point in time. It is an opinion of value, not an offer. Its real use is diagnostic: it shows an owner where value sits, what is suppressing it, and what can be repaired before marketing begins.
Most owners ask for a valuation because they want a number, and that instinct is a reasonable one. The argument of this article is that the number is worth less than the time it opens up. A valuation obtained before a sale is more useful as a preparation instrument than as a price, because the months between the valuation and the day the business is marketed are when most of the achievable value is either protected or lost. An owner meeting this subject for the first time usually needs a framework for valuing a business before a single figure means anything.
A valuation is an opinion of value, not a price
The words valuation and price are used interchangeably by almost everyone, including advisers. A valuation is a reasoned estimate of what a business is worth on a stated basis at a stated date. A price is what one identified buyer agrees to pay after negotiation, finance and legal work, and the two rarely match exactly.
HM Revenue and Customs draws the distinction with unusual clarity. Its Shares and Assets Valuation Manual explains that valuing unquoted shares in the statutory open market, for example under section 272 of the Taxation of Chargeable Gains Act 1992, assumes a hypothetical sale between a hypothetical willing seller and a hypothetical willing buyer. Neither of those parties exists. A real sale involves a named buyer with a particular reason for wanting this business, a particular lender and a particular tolerance for risk.
Goodwill is the part of a price that reflects reputation, customer relationships and earning capacity rather than tangible assets, and it is the part that moves most between a valuation and an offer. Three valuations of the same business, prepared on the same day for different purposes, can produce three different figures without any of them being wrong.
| Purpose of the valuation | Basis used | What the figure can be relied on for | What it cannot be relied on for |
| Open market sale | An estimate of what a buyer in the current market would be likely to pay for the business as it trades today, on the information a buyer would be given. | Setting a considered asking price, testing whether a sale would meet the owner’s personal objectives, and identifying the weaknesses a buyer will price. | The figure cannot bind a buyer, produce an offer, or hold its shape once trading, lease terms or lending conditions change. |
| Tax purposes | Statutory market value, which assumes a hypothetical sale in the open market between a hypothetical willing seller and a hypothetical willing buyer, as HM Revenue and Customs sets out. | Reporting a disposal, a gift or a share transfer to HM Revenue and Customs on the basis the legislation requires. | The figure is not a forecast of sale proceeds and should never be used as an asking price in a live sale. |
| Internal planning | The owner’s or the accountant’s working assumptions about maintainable earnings, applied consistently from one year to the next. | Tracking whether value is improving, testing whether a sale would fund retirement, and deciding whether to start preparing at all. | The figure carries no external validation and usually reflects the owner’s view of the business rather than a buyer’s. |
What the calendar does to a valuation
How useful a pre-sale valuation is depends almost entirely on how much time is left. At twenty-four months it is a planning document. At twelve months it is a work list. At the point of going to market it becomes a pricing decision, and by then most of what could have been changed has been settled.
At twenty-four months, the work with the longest lead time is still possible. Reducing the owner’s operational role, putting a second signature on supplier and customer relationships, renewing a lease that is running short and cleaning up the way accounts are prepared all need two reporting periods behind them before a buyer will believe them. At Blacks Brokers we find that the changes which move a figure most are precisely the ones that need two sets of accounts to prove, which is why twenty-four months is the point at which a valuation can still alter the outcome rather than describe it.
At twelve months, the realistic list is shorter and more specific: one clean full year of trading under the new arrangements, management accounts produced monthly rather than annually, contracts documented, and any dispute or unresolved liability closed. Work started later than that tends to be visible to a buyer as work in progress, which is not the same as evidence.
By the time the business is marketed, the figure has become an asking price, and the questions that follow belong to the mechanics of selling an owner-managed business rather than to valuation.
How owner earnings are adjusted before a multiple is applied
Adjusted earnings, not reported profit, are the starting point for almost every earnings-based valuation of an owner-managed business. The adjustment strips out costs and benefits that belong to the present owner personally, so that a buyer can see what the business would earn under different ownership. Adjusted EBITDA is earnings before interest, tax, depreciation and amortisation, after those one-off and owner-specific items have been removed.
Some adjustments a buyer will accept with little argument, because they are evidenced and repeatable: an owner’s salary set above or below a market rate for the role, pension contributions made for tax reasons, a family member on the payroll who does not work in the business, a vehicle run through the company, and genuinely exceptional legal or professional costs with paperwork behind them.
Others are contested, and in our experience the contested ones follow a pattern. Buyers resist any add-back that rests on the owner’s word rather than a document. They resist the removal of a poor year on the grounds that it was unrepresentative. They resist adding back marketing or repairs that the business will need to spend again. And where an owner works six days a week for a modest salary, a buyer does not accept the saving; the cost of a manager to replace those hours is deducted, not added back.
Which method is then applied to those earnings depends on the sector, the asset base and how reliable the profit record is, and the choice between the main business valuation methods is worth understanding before any multiple is discussed.
What a buyer tests when they interrogate an asking price
A buyer tests three things: whether the earnings are real, whether those earnings will continue without the current owner, and whether a lender will support the price. An asking price that fails any one of those tests is negotiated down regardless of how carefully it was calculated.
Accounts are the first thing a buyer reads and the first thing that dates. GOV.UK guidance on accounts and tax returns for private limited companies sets the deadline for filing annual accounts with Companies House at nine months after the end of the company’s financial year. A buyer reading filed accounts may therefore be looking at a period that closed well over a year earlier, which is why management information carries so much weight in a sale and why its absence is read as a warning.
The buyer is usually smaller than owners expect. Department for Business and Trade business population estimates for the UK and regions 2025 record 5.64 million private sector businesses with 0 to 49 employees at the start of 2025, out of 5.7 million in total. The realistic buyer for most owner-managed businesses is an individual or a small trade acquirer whose offer is limited by personal borrowing capacity rather than by strategic appetite.
Cost of finance sets a practical ceiling on that capacity. The House of Commons Library briefing on interest rates and monetary policy records that the Bank of England held Bank Rate at 3.75 per cent on 30 July 2026, following reductions made between August 2024 and December 2025. Debt service comes out of the same earnings the valuation was built on, so the rate environment quietly reprices every deal in the market.
Availability is a separate question from cost. The British Business Bank’s Small Business Finance Markets report published in March 2026 records gross bank lending to smaller businesses of £68 billion in 2025, an increase of 9 per cent on the previous year. Credit being available in general is not the same as credit being available for an acquisition, which lenders assess against the target’s earnings and security rather than the buyer’s enthusiasm.
What quietly reduces the price in owner-managed businesses
The features that cost owners the most money rarely appear in the accounts. A business can be profitable, growing and well regarded and still price poorly because of how it is built and how it is recorded.
Owner dependency is the most expensive of them, and it shows up in operational detail rather than in job titles. In the mandates Blacks Brokers handles, it looks like this: the owner is the only person who prices a job, the main supplier gives terms because of a twenty-year relationship, and a large share of customer contact runs through one mobile number. A buyer prices that as the cost of a manager plus a discount for the risk that the relationships do not transfer, and both come out of the multiple.
Lease assignment is the most common reason a completion date slips. A landlord has no reason to work to a sale timetable, and a consent process can generate a request for references, a rent deposit or a personal guarantee weeks after commercial terms are agreed. Where the unexpired term is shorter than the buyer’s lending term, the lease stops being a legal matter and becomes a pricing one.
Heads of terms, the short document recording the agreed shape of a deal before legal work begins, is where record-keeping problems surface. Buyers ask at that stage for monthly management accounts, an aged debtor list, turnover by customer and a staff schedule with contract dates and length of service. Businesses that cannot produce those within a fortnight lose momentum, and momentum is what carries a transaction through the weeks when nothing visible is happening.
Two further features consistently cost money. Where a small number of customers carry most of the turnover, a buyer asks what happens if the largest one leaves and prices the answer. And where working practices live in the owner’s head rather than in documents, the warranties and indemnities stage becomes slower and more expensive, because the seller is being asked to make contractual statements about the condition of the business and to compensate the buyer if those statements prove wrong.
Staff usually learn about a sale late, and that is deliberate. Confidentiality is protected through anonymised marketing, non-disclosure agreements signed before trading detail is released, and introductions made only once a buyer is credible and funded. That discipline protects the business during marketing, but it also means a buyer may reach completion having met very few of the people who run it, which is one more reason buyers pay for documented processes.
The case for getting a number now
Owners who want a valuation immediately are not being impatient, and three of their reasons are sound. A retirement cannot be planned around an unknown figure. Market conditions, tax rates and buyer appetite all move, so a long preparation programme carries its own risk. And a business that is already tidy, transferable and well documented gains nothing from waiting, particularly if a credible buyer is in front of it.
Preparation can also fail on its own terms. An owner who spends a year reducing dependency and loses two significant customers in the process ends up worse off than if they had gone to market straight away. Some improvements cost more than they return. None of that is an argument for delay as a principle.
The central claim survives all of this because getting a figure early and preparing are not alternatives. The mistake is not obtaining a number early; it is treating an early number as settled, publishing it as an asking price and leaving the underlying business unchanged for a year. A valuation that is read as a diagnosis loses nothing by being obtained twenty-four months out. A valuation that is read as a price starts decaying the day it is issued.
Asking prices in the market tell an owner very little in any case, because the useful evidence sits in completed business sales rather than in what is currently advertised.
What changes between a valuation and completion
A valuation describes a business on the day it was prepared, and four things typically move afterwards: trading performance, tax treatment, the terms of any lease or contract, and the lending conditions a buyer faces. An asking price built on a figure eighteen months old is worse than no figure at all, because it invites a buyer’s adviser to dismantle it and to treat everything else the seller says with the same scepticism.
Tax treatment is the clearest example. Business Asset Disposal Relief is a Capital Gains Tax relief that reduces the rate paid on qualifying gains when an owner sells all or part of a business. GOV.UK guidance on Business Asset Disposal Relief states that tax is paid at 18 per cent on gains on qualifying assets disposed of from 6 April 2026, at 14 per cent between 6 April 2025 and 5 April 2026, and at 10 per cent on or before 5 April 2025. An owner planning around a net figure calculated two years ago is planning around a rate that has since changed, and the eligibility conditions are a matter for a tax adviser rather than a broker.
Structure moves as well, and structure decides how much of a headline price actually arrives. In an asset sale the buyer takes selected assets and the trade; in a share sale the buyer takes the company with its history and its liabilities. Deferred consideration is a portion of the price paid on agreed dates after completion. An earn-out is a portion that depends on the business meeting agreed performance measures afterwards. A headline figure containing either one is not the same as money in a bank account, and no adviser can promise that the deferred element will be paid in full.
What to do with the figure once you have it
A pre-sale valuation earns its keep when it is used in order rather than read as a verdict.
- Read the basis and the date before the figure. A valuation prepared for tax, for planning or for an open market sale answers a different question in each case.
- Separate what can be changed from what cannot. Owner dependency, records, lease terms and customer concentration are usually addressable; sector conditions and the cost of finance are not.
- Decide when to test the market rather than whether to. That decision belongs to the owner, and it depends on personal timing as much as on the business.
None of this guarantees a price or a timescale. What it does is remove the avoidable reasons a good business sells for less than it should. Blacks Brokers offers a confidential valuation of your business for owners who are thinking about a sale, with no obligation to market it afterwards, and the conversation is often more useful than the number that comes out of it.
