Knowing how to value a business means working out the sustainable financial benefit a buyer could receive from owning it, then applying a valuation method that reflects the company’s sector, size, assets, growth prospects and risks.
For many established UK SMEs, the starting point is normalised EBITDA or adjusted profit multiplied by an appropriate market multiple.
Smaller owner-operated businesses may instead use Seller’s Discretionary Earnings (SDE), while asset-heavy companies, startups, professional practices and high-growth SaaS businesses may require different approaches.
Crucially, a business worth £1 million on an enterprise-value basis is not necessarily worth £1 million to its shareholders. Debt, surplus cash, working capital, tax and deal structure can all change the amount the owner actually receives.
How Do You Value a Business Step by Step?
A business owner carrying out an initial DIY valuation can use the following process:
- Gather at least three years of accounts and recent management figures.
- Identify sustainable revenue and profits.
- Normalise EBITDA or calculate SDE.
- Separate recurring income from one-off revenue.
- Analyse customer, supplier, employee and owner dependency.
- Select at least two suitable valuation methods.
- Research multiples for comparable businesses in the same sector and size range.
- Calculate enterprise value.
- Adjust for debt, surplus cash and other relevant balance-sheet items.
- Compare the result with recent transactions and alternative valuation methods.
- Consider the tax implications of the proposed sale structure.
- Use professional valuation advice where the figure will influence a transaction, tax position, dispute or court proceeding.
This process matters because simply multiplying last year’s profit by three, four or five is not a reliable business valuation.
Two companies generating exactly the same profit can have dramatically different values if one has contracted recurring revenue, a management team and hundreds of customers while the other depends on its founder and one major client.
What Information Is Needed to Value a Business?
Before choosing a formula, the owner needs reliable financial information.
Ideally, the valuation file should contain:
- The last three years of statutory accounts
- Current management accounts
- Monthly revenue
- Gross profit
- EBITDA or operating profit
- Cash-flow statements
- Aged debtors and creditors
- Existing loans and other debt
- Cash balances
- Stock
- Major assets
- Customer concentration
- Recurring-revenue figures
- Contracts and renewal dates;
- Employee costs
- Owner/director remuneration
- Supplier concentration
- Capital expenditure requirements
- Financial forecasts.
Historic numbers show what the business has achieved. Current management accounts show whether that performance has continued.
Forecasts then help determine whether a buyer is purchasing a stable company, a declining operation or a business with credible growth ahead.
Owners already using financial forecasts and business KPIs should therefore compare those projections with actual performance before relying on them in a valuation.
A buyer is unlikely to pay a premium simply because a spreadsheet forecasts 30% annual growth. The assumptions behind that forecast have to be credible.
What Are the Main Business Valuation Methods?
There is no universally correct valuation method.
Professional valuers commonly consider several approaches and decide which carries the most weight for the particular company and purpose.
ICAEW guidance similarly stresses that a valuation starts by defining what is being valued, when it is being valued, why the valuation is required and the appropriate basis of value.
| Valuation method | Best suited to | Main advantage | Main limitation |
| EBITDA multiple | Profitable established companies | Closely reflects how many SME deals are assessed | Requires reliable comparable multiples |
| SDE multiple | Small owner-operated businesses | Reflects the financial benefit available to an owner-operator | Add-backs can easily be overstated |
| P/E ratio | Profitable businesses and listed-company comparisons | Simple earnings-based calculation | Listed-company P/E ratios may not suit small private firms |
| Discounted Cash Flow | Businesses with predictable future cash flows | Focuses on future economic value | Highly sensitive to forecasts and discount rates |
| Net asset value | Asset-rich businesses | Relatively straightforward | Can ignore valuable goodwill and earnings |
| Revenue multiple | SaaS and selected high-growth businesses | Useful before mature profitability | Revenue alone says little about margins |
| Comparable transactions | Businesses in active M&A markets | Based on actual market behaviour | Comparable private-deal information can be difficult to obtain |
| Industry-specific method | Accountancy, hospitality and other specialist sectors | Reflects how that market actually trades | Rules of thumb can overlook company-specific risks |
ICAEW notes that industry rules of thumb do exist but warns that they may fail to capture differences between companies within the same industry.
That warning is important.
A valuation multiple is a starting benchmark, not an automatic price.
How Does an EBITDA Multiple Value a Business?
An earnings multiple is one of the most common approaches for established profitable businesses.
The basic calculation is:
Enterprise Value = Normalised EBITDA × Valuation Multiple
Suppose a company produces £250,000 of sustainable adjusted EBITDA and comparable businesses justify a 5× multiple.
Its indicative enterprise value would be:
£250,000 × 5 = £1,250,000
But £1.25 million is not necessarily what the owner receives.
The next calculation might be:
Equity Value = Enterprise Value – Debt + Surplus Cash
If the company has:
- enterprise value: £1,250,000
- debt: £200,000
- surplus cash: £75,000
the simplified equity value becomes:
£1,250,000 – £200,000 + £75,000 = £1,125,000
This enterprise-value/equity-value distinction is frequently missed in DIY business valuations.
International Valuation Standards describe enterprise value broadly as equity value plus debt-related liabilities minus cash or cash equivalents available to meet those liabilities.
Actual transactions can be more complicated because completion accounts, normal working capital, leases, shareholder loans, deferred consideration and other adjustments may also apply.
What Is Normalised EBITDA?
Normalised EBITDA attempts to show the sustainable earnings that a new owner could reasonably expect after removing unusual, personal or non-recurring items.
This is one of the most important stages in learning how to value a business.
The EBITDA shown in statutory accounts is not automatically the figure a buyer will accept.
Consider this company:
| Item | Amount |
| Reported EBITDA | £120,000 |
| Excess owner salary above market replacement cost | +£25,000 |
| One-off legal dispute | +£12,000 |
| Personal vehicle costs paid by company | +£8,000 |
| One-off non-recurring income | -£5,000 |
| Normalised EBITDA | £160,000 |
The adjusted figure is therefore £160,000 rather than £120,000.
Which Expenses Can Potentially Be Added Back?
Potential adjustments can include:
- Genuinely one-off professional fees
- Exceptional litigation costs
- Non-recurring restructuring expenditure
- Personal costs paid through the company
- Above-market remuneration
- One-off consultancy expenditure
- Unusual property costs
- Expenses that will definitely disappear after acquisition.
However, an owner cannot simply add back every expense they dislike.
Owner Salary Is Frequently Normalised Incorrectly
Suppose a founder is paid £90,000.
It might be tempting to add the entire £90,000 back to EBITDA.
But if a buyer would need to employ a managing director at £60,000 to replace the founder, only the £30,000 excess is potentially an appropriate adjustment.
Otherwise the valuation assumes that somebody will run the company for free.
Related-Party Rent Can Also Distort EBITDA
Suppose the company pays £30,000 a year to rent a building owned personally by the director, but equivalent commercial premises would cost £50,000.
Normalised EBITDA should potentially be reduced by £20,000.
The reverse can apply where the company is paying excessive rent to a related party.
The objective is not to produce the highest possible EBITDA. It is to estimate maintainable earnings under normal commercial ownership.
What Is Seller’s Discretionary Earnings?
Seller’s Discretionary Earnings, or SDE, is commonly used for smaller businesses where the owner actively works in the company.
A simplified calculation is:
SDE = Profit + Owner Compensation + Certain Personal/Discretionary Expenses + Valid One-Off Costs
It attempts to estimate the total financial benefit available to one owner-operator.
An SDE approach can therefore be more appropriate for a small shop, trade business, agency or owner-managed service company than conventional corporate EBITDA.
As businesses become larger and employ professional management, EBITDA generally becomes more useful.
What Business Valuation Multiples Are Used in the UK?
There is no official UK government table of business valuation multiples.
Multiples move with interest rates, financing conditions, buyer demand, business size, sector performance and the quality of the particular company.
Recent UK SME market guides illustrate just how wide the differences can be.
| UK business type | Common valuation basis | Indicative multiple |
| Accountancy and bookkeeping | Gross recurring fees | Around 0.8–1.2× GRF |
| Hospitality, pubs and restaurants | Maintainable profit / SDE | Around 2.5–6× |
| E-commerce and DTC | Net profit / SDE | Around 2.5–5× |
| Construction | Adjusted earnings | Around 2.5–4.5× |
| Logistics and distribution | EBITDA | Around 3–5× |
| Manufacturing and engineering | EBITDA | Around 3.3–5× |
| Plumbing, HVAC and trades | Adjusted profit / SDE | Around 3–5× |
| IT managed services | EBITDA | Around 6–12× |
| Dental practices | EBITDA | Around 6.5–9.5× |
| Care homes | EBITDA | Around 5–12× |
These figures are indicative market ranges, not guaranteed sale prices. Recent sector data published by Dealdoor, for example, places manufacturing around 3.3–5× EBITDA, hospitality around 2.5–6× maintainable profit, ecommerce around 2.5–5× net profit and MSP businesses around 6–12× EBITDA.
Another 2026 UK SME benchmark places engineering and precision manufacturing businesses with less than £1 million of adjusted EBITDA around 3.5–5.5×, professional services around 3.5–5.5× and software/SaaS around 5–8×, demonstrating why the source, size bracket and methodology behind any multiple matter.
Why Can Two Sources Give Different Multiples?
Because they may be measuring different things.
One source could be describing:
- EBITDA
While another uses:
- Sde
- Net profit
- Gross recurring fees
- Revenue
- Fair maintainable operating profit.
The transaction size may also be different.
A company generating £100,000 of EBITDA may trade at a substantially lower multiple than a company generating £5 million of EBITDA, even within the same industry.
That is why owners should never copy an impressive multiple from a large listed company and apply it directly to a small private business.
What Makes a Business Multiple Higher?
Businesses generally attract stronger valuation multiples where the buyer faces less risk or has greater confidence in future growth.
Important factors include:
Recurring Revenue: Subscription income, long-term contracts and repeat client fees provide greater visibility than unpredictable one-off sales.
Low Customer Concentration: A business earning 45% of revenue from one customer carries considerably more risk than one whose revenue is spread across hundreds of customers.
Low Owner Dependency: A company that can operate for several weeks without its founder is usually more transferable than one where the founder personally controls sales, customer relationships, pricing and operations.
Strong Management: A competent second-tier management team reduces the operational risk of ownership changing.
Revenue and Profit Growth: Consistent profitable growth generally supports a stronger valuation than stagnant or declining earnings.
Strong Margins: Buyers care not only about turnover but also about how efficiently that revenue becomes cash and profit.
Intellectual Property: Proprietary software, patents, valuable brands, data, specialist processes and other defensible intellectual property can support value.
Contracted Future Revenue: Signed contracts and recurring subscriptions generally carry more valuation weight than an unconfirmed sales pipeline.
Low Capital Requirements: A company that can grow without continually purchasing machinery, stock or property may generate more distributable cash.
What Can Reduce a Business Valuation?
The opposite characteristics can push the multiple down.
Common valuation discounts arise from:
- Dependence on the founder
- Declining revenue
- Declining margins
- Customer concentration
- Supplier concentration
- High employee turnover
- Weak financial records
- Unresolved litigation
- Tax disputes
- Regulatory risk
- Excessive working-capital requirements
- Obsolete stock
- Ageing equipment
- Underinvestment
- Short property leases
- Unreliable forecasts
- Cybersecurity problems
- Loss of intellectual-property protection
- Unusual related-party transactions.
A business can therefore become more valuable without substantially increasing revenue simply by reducing its risk profile.
How Should a Business Be Valued for Different Purposes?
The purpose of a valuation matters.
A figure prepared for an informal sale discussion is not automatically suitable for divorce proceedings, probate or a shareholder dispute.
| Purpose | Valuation emphasis |
| Selling the company | Market evidence, maintainable earnings and buyer demand |
| Buying a company | Sustainable earnings, risk, synergies and required investment |
| Raising equity | Future growth, market opportunity, dilution and investor return |
| Succession planning | Transferable earnings, management depth and tax planning |
| Management buyout | Maintainable cash flow, financing capacity and market evidence |
| Shareholder dispute | Appropriate legal/contractual basis and independent evidence |
| Divorce | Court instructions and defensible independent valuation |
| Probate | Relevant market value at the applicable valuation date |
| Tax/HMRC purposes | Appropriate statutory tax valuation basis |
| Internal planning | Indicative range may often be sufficient |
International Valuation Standards recognise business valuations for uses including acquisitions, mergers, sales, taxation, litigation, insolvency and financial reporting.
They require the appropriate basis of value to be identified for the assignment.
That is why someone should not assume there is one permanently correct answer to the question: “What is my business worth?”
The correct question is often:“What is this business worth, on what date, to whom and for what purpose?”
How Does an Asset-Based Business Valuation Work?
An asset-based valuation starts with the assets owned by the company and deducts its liabilities.
A simplified formula is:
Net Asset Value = Fair Value of Assets – Liabilities
Suppose a manufacturing company owns:
- Property worth £900,000
- Machinery worth £350,000
- Stock worth £180,000
- Receivables worth £120,000
- Cash of £100,000.
- Total assets are £1.65 million.
If liabilities total £550,000:
Net asset value = £1.65 million – £550,000 = £1.1 million
An asset approach can be particularly important for:
- Property companies
- Investment companies
- Asset-heavy manufacturers
- Agricultural businesses
- Holding companies
- Businesses being liquidated.
It can be much less useful for a profitable consultancy or software company whose main value lies in people, customers, contracts or intellectual property rather than physical assets.
How Does Discounted Cash Flow Value a Business?
A Discounted Cash Flow valuation estimates future cash generated by the company and converts those future amounts into today’s value.
In simplified terms:
Business Value = Present Value of Forecast Future Cash Flows + Terminal Value
DCF can be powerful because an investor is ultimately buying future economic returns rather than historic accounts.
But it has an obvious weakness.
Small changes in:
- Revenue growth
- Profit margins
- Capital expenditure
- Working capital
- Terminal growth
- Discount rate
can produce large differences in the valuation.
DCF is therefore most credible where future cash flows can be forecast reasonably reliably.
A five-year forecast for an established contracted-service business has more evidential value than a five-year forecast for a six-month-old startup still searching for product-market fit.
How Are SaaS and High-Growth Businesses Valued?
High-growth software companies can be difficult to value using traditional EBITDA multiples because some deliberately reinvest heavily and produce little accounting profit.
Investors may instead examine:
- Annual recurring revenue
- Monthly recurring revenue
- Arr growth
- Gross margin
- Customer churn
- Net revenue retention
- Customer acquisition cost
- Lifetime value
- Burn rate
- Rule of 40 performance
- Recurring versus services revenue.
Recent UK valuation material also notes that high-growth SaaS companies can be priced using revenue rather than EBITDA.
However, an ARR multiple should not be applied blindly.
£2 million of highly sticky contracted ARR with strong gross margins is not economically equivalent to £2 million of low-margin revenue with high churn.
How Are Accountancy Practices Valued?
Accountancy businesses are an excellent example of why one valuation formula cannot be used across every sector.
Smaller UK accountancy practices are frequently discussed in terms of gross recurring fees, or GRF.
Recent UK market material indicates a broad starting range of roughly 0.8–1.2× recurring fees, although larger firms increasingly move towards EBITDA-based valuations.
The actual figure is influenced by:
- Recurring-fee percentage
- Client retention
- Average client size
- Client concentration
- Service mix
- Staff continuity
- Owner dependency
- Profitability
- Technology and systems
- Geographic fit
- Payment and clawback arrangements.
That means a £500,000 fee book is not automatically worth £500,000.
What Is Goodwill Worth in a Business Valuation?
Goodwill represents value that cannot simply be attributed to identifiable physical assets.
It can arise from:
- Brand reputation
- Customer relationships
- Recurring contracts
- Workforce expertise
- Location
- Intellectual property
- Systems
- Distribution relationships
- Market position.
A profitable consulting company might own only £30,000 of computers and furniture but still sell for £1 million because buyers are purchasing its earnings, clients, reputation and systems.
Goodwill should therefore not simply be guessed and added on top of an earnings valuation.
In many earnings-based transactions, expected goodwill is already reflected in the multiple being paid.
Adding an arbitrary goodwill figure afterwards can double-count the same economic value.
Can Turnover Be Used to Value a Business?
Sometimes, but turnover alone is normally a poor measure of value.
Consider two companies:
| Business A | Business B | |
| Turnover | £2,000,000 | £2,000,000 |
| EBITDA | £80,000 | £400,000 |
| EBITDA margin | 4% | 20% |
Both generate exactly the same revenue.
Their economics are completely different.
Revenue multiples are more relevant in sectors where revenue quality itself is highly informative, such as certain SaaS companies or recurring-revenue businesses.
Even then, margins, churn, growth and cash requirements cannot be ignored.
How Many Times Profit Is a Small Business Worth in the UK?
There is no universal rule saying a UK small business is worth three, four or five times profit.
Broad SME market data commonly places established private businesses across a wide range, often somewhere around 2× to 6× adjusted earnings, with particular sectors falling above or below that range.
The relevant multiple depends on:
- What definition of profit is being used
- Sector
- Size
- Recurring income
- Growth
- Customer concentration
- Management quality
- Owner dependency
- Transaction structure
- Prevailing m&a conditions.
A buyer may therefore offer 2.5× earnings for one company and 7× earnings for another without either valuation being inherently wrong.
What Is a Realistic Worked Example of Valuing a UK Business?
Consider a fictional UK digital agency.
Step 1: Review the Accounts
The company reports:
| Metric | Amount |
| Annual turnover | £600,000 |
| Reported EBITDA | £120,000 |
| Cash | £70,000 |
| Interest-bearing debt | £90,000 |
Step 2: Normalise EBITDA
Further analysis identifies:
| Adjustment | Effect |
| Reported EBITDA | £120,000 |
| Excess owner salary | +£25,000 |
| One-off legal costs | +£12,000 |
| Personal vehicle costs | +£8,000 |
| Non-recurring grant income | -£5,000 |
| Adjusted EBITDA | £160,000 |
Step 3: Assess Business Quality
The agency has several positive features:
- 65% recurring or retained revenue
- No customer contributes more than 12% of turnover
- Five years of profitable trading
- Management can handle normal operations
- Revenue increased 9% in the latest year.
There are also risks:
- The founder still generates around 35% of new sales
- Several major client contracts renew annually
- Staff costs are increasing
Step 4: Select an Earnings Multiple
Suppose comparable evidence supports a working range of approximately 3.5× to 5.5× adjusted EBITDA.
Because the company has strong recurring revenue but retains some founder dependency, the owner uses 4.5× as an initial central case.
£160,000 × 4.5 = £720,000 enterprise value
Step 5: Convert Enterprise Value to Equity Value
Assume £40,000 of the £70,000 cash balance is needed as normal operating cash.
Surplus cash is therefore £30,000.
The simplified calculation becomes:
**£720,000 enterprise value
- £90,000 debt
- £30,000 surplus cash
= £660,000 equity value**
Step 6: Cross-Check the Result
A comparable-transactions analysis produces an estimated range of £650,000 to £750,000.
A conservative DCF produces approximately £640,000 to £700,000.
Net tangible assets are only around £170,000 because the agency is not asset-heavy.
The asset value therefore receives little weighting.
Indicative Conclusion
A reasonable initial equity valuation might be approximately:
£650,000 to £700,000
rather than pretending that £660,000 is an objectively precise answer.
That range could still change after due diligence, negotiation and the final treatment of working capital, debt, cash and deferred consideration.
Does Tax Affect What a Business Is Really Worth to the Owner?
Yes.
A £1 million sale price and £1 million in after-tax proceeds are very different things.
This is particularly important in the UK because the tax treatment can depend heavily on whether the transaction is:
- A share sale
- An asset sale
- A sole-trader business sale
- A partnership disposal
- A liquidation
- Another form of restructuring.
What Is the Business Asset Disposal Relief Rate in 2026?
For qualifying disposals made from 6 April 2026, Business Asset Disposal Relief can reduce the applicable Capital Gains Tax rate to 18% on qualifying gains within the available lifetime allowance.
The lifetime BADR limit remains £1 million of qualifying gains per individual.
The rate was:
- 10% up to 5 April 2025
- 14% from 6 April 2025 to 5 April 2026
- 18% from 6 April 2026.
Qualifying conditions apply, including relevant two-year ownership and trading requirements depending on the disposal. BADR should therefore never be assumed automatically.
A Simplified BADR Example
Suppose a shareholder sells qualifying shares and realises a taxable qualifying gain of £500,000.
Ignoring other gains, losses and allowances for illustration:
£500,000 × 18% = £90,000 CGT
That makes the tax-adjusted economics of the sale materially different from simply looking at the agreed business valuation.
Share Sale and Asset Sale Tax Can Be Very Different
This distinction is particularly important for limited companies.
If an individual shareholder sells their shares, the shareholder can be liable to Capital Gains Tax on the gain and may potentially qualify for BADR.
If the company itself sells its business assets, the company can instead face Corporation Tax consequences on chargeable gains or profits.
Additional tax consequences can then arise when the proceeds are extracted by shareholders. GOV.UK specifically distinguishes these situations.
Therefore:
“The business is worth £800,000”
does not answer:
“How much will the owner keep after selling it?”
Tax advice should normally be taken before transaction terms are agreed rather than after the sale structure has effectively been fixed.
What Common Business Valuation Mistakes Should Owners Avoid?
Using Only One Valuation Method
One formula can produce a misleading result.
A stronger valuation normally uses a primary method and at least one cross-check.
Applying the Multiple to the Wrong Profit Figure
An EBITDA multiple should be applied to defensible normalised EBITDA, not automatically to net profit, gross profit or turnover.
Adding Back Every Owner Expense
Buyers will challenge aggressive add-backs.
Every adjustment should have a clear commercial explanation.
Forgetting Replacement Management Costs
Removing the founder’s full remuneration without budgeting for someone to perform their job exaggerates value.
Confusing Enterprise Value With Equity Value
Debt and cash can significantly change shareholder proceeds.
Ignoring Working Capital
Buyers commonly expect an agreed normal level of working capital to remain in the business at completion.
Using Listed-Company Multiples for Small Companies
A multinational listed company has greater liquidity, scale, management depth and access to capital than most privately owned SMEs.
Its multiple is rarely directly comparable.
Using Stale Comparable Deals
Market conditions change.
A transaction completed during an acquisition boom several years ago may no longer reflect today’s financing environment.
Ignoring Owner Dependency
If customers, staff and suppliers are primarily loyal to the founder rather than the company, a buyer is taking additional retention risk.
Valuing Emotion Rather Than Economics
Years of personal sacrifice do not automatically translate into transferable economic value.
A buyer pays for the future financial benefits they expect to receive.
Ignoring Deal Structure
An offer of £1 million payable entirely on completion may be more valuable than £1.2 million where £500,000 depends on uncertain earn-out targets.
Headline price and economic value are not always the same thing.
How Can an Owner Increase the Value of a Business Before Selling?

Business value can often be improved before a transaction.
Owners preparing two or three years in advance can focus on:
- Increasing recurring revenue
- Reducing customer concentration
- Documenting processes
- Building management depth
- Reducing founder dependency
- Protecting intellectual property
- Cleaning up personal expenses
- Renegotiating problematic contracts
- Improving margins
- Resolving legal disputes
- Improving management reporting
- Reducing obsolete stock
- Strengthening cash conversion
- Securing longer customer contracts
- Documenting supplier agreement
- Retaining key employees.
For example, replacing informal monthly arrangements with properly documented recurring contracts could reduce perceived revenue risk.
Similarly, moving customer relationships from the founder to an account-management team can make earnings more transferable.
This is why valuation should ideally begin well before the business is advertised for sale.
Can Someone Value Their Own Business?
Yes, for initial planning.
A business owner can usually create a useful indicative range using:
- Normalised EBITDA or sde
- A defensible sector multiple
- Comparable transactions
- Balance-sheet adjustments
- A second valuation method as a cross-check.
A DIY valuation can be perfectly adequate when an owner simply wants to understand whether their business might be worth £300,000, £700,000 or £1.5 million.
Professional assistance becomes more important when the valuation affects substantial money or a third party needs to rely on it.
When Is a Professional Business Valuation Worth Paying For?
Professional valuation is particularly sensible for:
- Business sales
- Acquisitions
- Management buyouts
- Shareholder disputes
- Divorce proceedings
- Probate
- Tax valuations
- Emi or employee share arrangements
- Investment rounds
- Complex corporate restructurings
- Minority shareholdings.
The required valuer should match the purpose.
For corporate transactions, relevant experience might include an ACA/ICAEW background, corporate-finance experience or the ICAEW/CISI CF Corporate Finance qualification. ICAEW says the CF designation reflects relevant corporate-finance expertise and experience.
RICS also participates in international business-valuation terminology and standards work, while International Valuation Standards provide a recognised framework for valuation engagements.
Credentials alone are not enough.
A business owner should also ask:
- How many similar businesses has the valuer valued?
- Which valuation methods will be used?
- Where will comparable transaction data come from?
- How will EBITDA adjustments be assessed?
- Is the valuer independent of a potential buyer?
- Does the report meet the intended legal or tax purpose?
- Will the person signing the valuation defend their assumptions?
- Is the fee fixed or linked to the valuation produced?
A broker offering a “free valuation” may still be useful for understanding likely sale-market demand, but owners should recognise that a broker seeking a sale mandate may not have the same role as an independent valuation professional.
How Much Does a Professional Business Valuation Cost in the UK?
There is no standard UK valuation fee.
Published pricing varies considerably according to the complexity and purpose of the work.
Current examples include independent SME valuation services advertised from around £495, while other providers publish fees around £1,950 to £3,000 for formal reports.
More complex valuation work can cost considerably more. One current UK pricing survey estimates formal reports elsewhere in the market can extend from around £2,000 to £10,000 or more.
A £500 indicative report should therefore not automatically be compared with a £10,000 expert valuation prepared for litigation.
The scope is different.
Owners should compare:
- Intended use
- Evidence supplied
- Independence
- Methodology
- Report depth
- Professional qualifications
- Comparable-deal research
- Whether expert evidence is required.
What Is a Simple Business Valuation Calculator Formula?
For an established profitable SME, a useful first-pass calculation is:
Step 1
Reported EBITDA
- Valid add-backs
- Required normalisation adjustments
= Adjusted EBITDA
Step 2
Adjusted EBITDA × Selected Market Multiple
= Enterprise Value
Step 3
Enterprise Value
- Debt
- Surplus cash
± agreed balance-sheet adjustments
= Indicative Equity Value
For example:
£200,000 adjusted EBITDA × 4.5 = £900,000 enterprise value
Then:
£900,000 – £150,000 debt + £50,000 surplus cash = £800,000 indicative equity value
A useful interactive calculator for this page could therefore ask readers for:
- Annual turnover
- Reported EBITDA or profit
- Owner salary
- One-off expenses
- Personal/discretionary expenses
- Required replacement-management cost
- Sector
- Selected multiple
- Debt
- Cash
- Required operating cash.
The calculator could then display:
- Normalised earnings
- Low valuation
- Central valuation
- High valuation
- Enterprise value
- Estimated equity value.
That would be more useful than returning one falsely precise number.
What Is the Best Way to Value a Business?
The strongest business valuation rarely comes from one formula.
For most established UK SMEs, a practical approach is to:
- Calculate maintainable earnings
- Normalise EBITDA or sde carefully
- Apply a realistic sector and size-adjusted multiple
- Calculate enterprise value
- Convert enterprise value to equity value
- Compare the result with recent market transactions
- Cross-check against dcf or asset value where appropriate
- Adjust for company-specific risks
- Consider the transaction structure and tax consequences.
The final result should normally be presented as a defensible valuation range, particularly during initial planning.
For example, saying a business is reasonably worth £1.1 million to £1.3 million is often more credible than claiming it is worth exactly £1,217,463.
Valuation is partly mathematical, but the numbers have to reflect commercial reality.
Final Thoughts
Understanding how to value a business starts with recognising that turnover, profit and value are not the same thing.
A credible UK business valuation should identify sustainable earnings, remove unusual accounting distortions, select a method appropriate to the industry and purpose, apply realistic market evidence and then distinguish enterprise value from the actual equity value attributable to the owner.
For many established SMEs, normalised EBITDA or SDE combined with comparable market multiples provides the most practical starting point.
But that result should still be tested against the company’s assets, future cash flows, customer quality, recurring revenue, management strength and risk.
Owners should also consider tax before focusing entirely on headline valuation. From 6 April 2026, qualifying BADR gains are taxed at 18%, while share sales and company asset sales can produce substantially different tax outcomes.
Ultimately, the most useful valuation is not the highest number an owner can justify.
It is the range that a knowledgeable buyer, investor, adviser or independent valuer can examine and still find commercially defensible.
Frequently Asked Questions
How Do You Calculate the Value of a Business?
One common method is to calculate normalised EBITDA and multiply it by an appropriate market multiple. Debt is then normally deducted and surplus cash added when moving from enterprise value to equity value. Other methods such as DCF, net asset value and comparable transactions should also be considered.
How Many Times Profit Is a Business Worth?
There is no universal figure. Many smaller UK businesses can fall somewhere around 2–6× adjusted earnings, while certain specialist, recurring-revenue and high-growth businesses can command substantially higher multiples.
Is a Business Worth Three Times Its Profit?
It can be, but three times profit is not a universal valuation rule. The correct multiple depends on the definition of profit, sector, size, growth, recurring revenue, risks, owner dependency and market conditions.
Should Turnover or Profit Be Used to Value a Business?
Profit or cash-generating capacity is more useful for most mature businesses. Revenue multiples are more common in certain high-growth or recurring-revenue sectors such as SaaS.
Can Someone Value Their Own Business?
Yes. A DIY valuation can produce a useful planning range, particularly for straightforward owner-managed businesses. Professional advice becomes more important for actual transactions, tax, disputes, divorce, probate or other situations where a third party will rely on the result.
Is EBITDA the Same as Business Value?
No. EBITDA is an earnings measure. A valuation multiple may be applied to normalised EBITDA to estimate enterprise value.
What Is the Difference Between Enterprise Value and Equity Value?
Enterprise value broadly represents the value of the underlying business operations to providers of capital. Equity value represents the value attributable to shareholders after relevant debt, cash and other adjustments.
Does Cash in the Bank Increase a Business Valuation?
Surplus cash can increase the value attributable to shareholders, but buyers usually expect sufficient cash and working capital to remain in the company for normal operations. Not every pound in the bank should therefore automatically be added to the purchase price.
Does Debt Reduce the Value of a Business?
Debt normally reduces the amount ultimately attributable to shareholders when moving from enterprise value to equity value, although the exact treatment depends on the transaction agreement.
What Multiple Is Used for a Small Business?
There is no fixed small-business multiple. Sector, earnings size, revenue quality, recurring income, customer concentration and owner dependency all influence the appropriate range.
Does Goodwill Get Added to a Business Valuation?
Not necessarily. An earnings valuation normally already reflects much of the company’s goodwill through the multiple being applied. Adding a separate arbitrary goodwill figure can result in double counting.
How Much Does a Business Valuation Cost?
Simple independent SME valuations can be available from several hundred pounds, while formal or complex assignments can cost several thousand pounds or more. The purpose and required level of evidence are more important than price alone.
Does Business Asset Disposal Relief Still Apply in 2026?
Yes, subject to eligibility. For qualifying gains on disposals from 6 April 2026, the BADR Capital Gains Tax rate is 18%, with qualifying gains subject to the applicable £1 million lifetime limit.
What Is the Most Accurate Business Valuation Method?
There is no single method that is always most accurate. Established profitable SMEs are commonly assessed using sustainable earnings and market multiples, while asset-rich businesses may require greater emphasis on net assets and businesses with predictable long-term cash flows may justify a DCF approach.
