In short: To sell a business in the UK, prepare clean financials, set a realistic valuation, protect confidentiality, write a clear listing, screen buyers, manage due diligence and use legal, tax and accounting advice before completion.
Selling a business is one of the most significant financial decisions you will make. Done well, it rewards years of work. Done badly, it costs time, money and stress — and sometimes falls through entirely.
This guide walks you through every stage of the process in plain language: from deciding whether you are ready to sell, through to completing the deal and handing over the keys. It is written for UK business owners selling independently or through a marketplace, not for those selling to private equity or using a corporate finance adviser (though much of the process is the same).
Quick Answer
To sell a business in the UK, first prepare the business so buyers can understand and verify it. That means organising accounts, management figures, contracts, lease documents, staff information, assets, stock, debts and tax and VAT records. Next, set a realistic asking price based on maintainable profit, risk, assets and buyer demand. Protect confidentiality by sharing information in stages and using NDAs where appropriate. Once buyers enquire, screen them before sharing sensitive documents. Offers should normally be subject to due diligence, finance, legal review, lease checks and tax advice. Completion should include proper legal documents, payment, transfer of assets or shares, staff communication and a structured handover.

Step 1: Decide whether the business is ready to sell
Before you list, be honest about where the business actually stands. Buyers will find out during due diligence what you know right now. The earlier you fix problems, the better your chances of a clean sale at a fair price.
Ask yourself these questions:
Are the accounts clean, up to date and filed at Companies House?
Can the business operate without you day-to-day, or are you the product?
Are key customers, contracts and supplier relationships documented and transferable?
Is there a lease in place, and how many years are left on it?
Are there any outstanding debts, disputes, HMRC liabilities or legal issues?
Do staff have proper employment contracts?
If the answer to several of these is "no" or "not really", you are not ready to list yet. Spend three to six months getting the business into a presentable state first. This is called preparing for sale, and it almost always results in a better price and a faster transaction.
Buyers pay for businesses that look and feel transferable. They discount heavily for risk, mess and dependency on the founder.

Step 2: Prepare your financial story
This is the stage most sellers underestimate. Buyers do not just look at headline profit — they want to understand the real financial picture of the business, including what it would look like under new ownership.
What to pull together:
Three years of accounts, where available — for limited companies, buyers may compare your figures with filings at Companies House. Sole traders and partnerships should prepare tax returns, management figures, bank records and accountant-prepared summaries where available. If your accounts are late, get them in order before listing.
Management accounts — up-to-date monthly or quarterly figures showing recent trading. If you only have year-end accounts, buyers will worry about what has happened since.
VAT returns — these cross-reference your declared turnover and give buyers a secondary source of evidence.
Payroll records — headcount, salaries, any informal payments to family members.
Revenue breakdown — by customer, product, channel or contract if possible. Buyers want to know where the money comes from and whether it is recurring or lumpy.
Adjusted EBITDA and add-backs
Most small business valuations are based on adjusted EBITDA — earnings before interest, tax, depreciation and amortisation, adjusted for one-off or owner-specific costs. Common add-backs include:
Owner salary above what a replacement manager would cost
Personal vehicle costs run through the business
One-off professional fees (for example, legal costs from a one-time dispute)
Premises costs that will not apply post-sale (for example, if you own the building and the buyer will rent it)
You should prepare a clear add-back schedule with explanations. Buyers and their accountants will question every add-back, so be ready to justify each one with documentation.
Debts and liabilities
Be clear about what debts sit in the business — director loans, outstanding HMRC liabilities, finance agreements, lease obligations. These affect valuation and will be scrutinised. Surprises at due diligence stage kill deals.

Step 3: Understand valuation before you list
Overpricing is the single most common reason businesses do not sell. An overpriced listing sits on the market, attracts no serious buyers, and becomes stale — which then makes it harder to sell even after a price reduction.
How UK small businesses are typically valued
Most small and medium UK businesses are valued on a multiple of adjusted EBITDA or Seller's Discretionary Earnings (SDE). The multiple depends on:
Sector — some sectors attract higher multiples than others. A profitable SaaS business might achieve 4–6x EBITDA; a busy café might achieve 2–3x.
Earnings quality — recurring revenue, long-term contracts and a diverse customer base attract higher multiples. Single-customer dependency or seasonal volatility pushes them down.
Growth trajectory — a business growing at 20% a year is worth more than one in decline, even at the same profit level.
Owner dependency — if the business cannot function without you, buyers will discount for the transition risk.
Lease and assets — a long, assignable lease adds value. A short lease with no renewal option creates risk.
Staff — a capable, stable team reduces handover risk and supports a higher price.
These ranges are broad market examples only. They are not a valuation and should not be relied on to price your business. Actual value depends on profit quality, buyer demand, deal structure, risk, assets, lease, staff, contracts and professional advice.
Asset-based valuation
Some businesses — particularly those with limited profit but significant physical assets — are valued on assets rather than earnings. This includes some manufacturing businesses, property-related businesses and asset-heavy trade businesses.
Getting a realistic figure
Marketplaces can help sellers understand how similar businesses are presented and priced, but asking prices are not the same as completed sale prices. Use them as market context, not as a valuation. For a reliable figure, use a professional valuer or an accountant with transaction experience in your sector.
Which route should you use to sell?
The route you choose affects how much control you have, what it costs and how long it takes.
Marketplace — Best for: Smaller owner-managed businesses. Main caution: Seller must manage enquiries and screening.
Broker — Best for: Sellers wanting more support. Main caution: Check fees, lock-ins and service scope.
M&A / corporate finance adviser — Best for: Larger or complex deals. Main caution: Usually higher cost and more formal process.

Step 4: Protect confidentiality from the start
One of the biggest risks in selling a business is that the wrong people find out too early. Staff may leave if they hear the business is for sale. Competitors may use it against you. Customers may get nervous. Suppliers may pull credit terms.
What should be public and what should not
Your listing can and should be visible to buyers — that is the point. But what it contains matters. A public listing should include the sector, location at region level, general size, financial headline and what is included. It should not include your trading name, specific address, customer names, full accounts or staff details.
Use an NDA before sharing detailed information
Before you share management accounts, customer lists, supplier contracts or detailed financials, ask the buyer to sign a non-disclosure agreement (NDA). This is standard practice and a serious buyer will not object. If they do object, that is worth noting.

Step 5: Write a listing that attracts serious buyers
A good listing is not a sales pitch. It is a clear, honest description that gives a serious buyer enough information to decide whether they want to know more. Vague listings attract time-wasters. Listings that try to hide problems attract no one.
What a strong listing includes
What the business does — in plain English, not marketing language. What does it actually sell or provide, and to whom?
Why it is attractive — what makes this business worth buying? Recurring revenue? Established customer base? Strong reputation? Growth potential?
Financial headline — turnover and adjusted profit (or SDE) for the most recent year, with a brief note on trend. Buyers will not enquire without seeing some financial evidence.
What is included — assets, stock, goodwill, equipment, intellectual property, website, social media accounts.
Why you are selling — buyers always ask. Give an honest answer. Retirement, health, relocation and portfolio restructuring are all accepted and credible reasons.
Handover support — how long will you stay involved to support the new owner? Three months is typical. Longer is reassuring for more complex businesses.
What to avoid
Avoid phrases like "serious enquiries only", "incredible opportunity" or "must be seen to be appreciated". These are noise. Buyers skim dozens of listings — clear numbers and plain facts win every time.

Step 6: Screen buyers before sharing anything sensitive
Not everyone who enquires is a genuine buyer. Some are competitors researching the market. Some are dreamers with no funding. Some are simply wasting your time. Screening buyers protects your confidentiality and your time.
Questions to ask every enquirer
Before sharing anything beyond the public listing, ask:
Are you buying personally, or through a company?
How are you planning to fund the purchase — personal funds, bank finance, business loan?
Have you bought a business before?
Why are you interested in this particular business?
Are you willing to sign an NDA?
You do not need to interrogate people, but you do need answers before you open the books. A serious buyer will understand and cooperate. Anyone who refuses or deflects is not ready to buy.
Ask for proof of funds
Before entering heads of terms, ask for evidence that the buyer can actually fund the purchase. This can be a bank statement, a letter from a lender or a confirmation from a financial adviser. It is entirely reasonable and protects you from wasting months on someone who cannot complete.

Step 7: Handle offers, heads of terms and due diligence
Once a buyer is serious, the process moves through three connected stages: offer, heads of terms, and due diligence.
Receiving and assessing an offer
An offer is not binding at this stage. Treat it as an opening position. Consider not just the price but the structure:
Is it a full cash offer at completion, or does it include deferred consideration or an earn-out?
Does it include seller finance — where you loan part of the price to the buyer?
Is the price subject to working capital, stock or debt adjustments at completion?
What conditions is the offer subject to? Finance, due diligence, lease consent?
A higher headline price with heavy conditions can be worth less than a cleaner lower offer.
Read more:What is seller finance? | What is an earn-out? | Working capital in a business sale
Heads of terms
Heads of terms (sometimes called a letter of intent) set out the agreed key terms before legal documentation begins. They typically cover:
Agreed price and payment structure
What is included and excluded from the sale
Exclusivity period — how long the buyer has to complete before you can talk to other buyers
Conditions to be satisfied
Target completion date
Heads of terms are usually not legally binding (except for exclusivity and confidentiality clauses), but they matter. They set expectations for both parties and give the lawyers a framework to work from.
Read more:Heads of terms in a business sale | Exclusivity in a business sale
Due diligence
Due diligence is the buyer's formal investigation of the business. They will go through your accounts, contracts, leases, staff arrangements, HMRC position, assets and liabilities in detail. This is normal and necessary — do not be defensive about it.
Common due diligence requests include:
Three years of accounts and management accounts
Bank statements
VAT returns
PAYE and payroll records
Key customer contracts
Supplier agreements
The lease and any side letters
Equipment finance agreements
Staff contracts and the org chart
Details of any pending disputes, claims or HMRC enquiries
Intellectual property registration
Prepare a data room — a secure shared folder containing all of this documentation — before you start marketing. This speeds up the process significantly and signals to buyers that you are organised and serious.

Step 8: Get the legal and tax structure right
This is where professional advice is not optional — it is essential. The legal and tax structure of the deal affects how much you actually keep from the sale.
Share sale vs asset sale
Most UK business sales are structured as either a share sale or an asset sale.
In a share sale, the buyer purchases the company itself — all its assets, contracts, liabilities and history transfer automatically. This is often preferred by sellers because it is cleaner and may qualify for Business Asset Disposal Relief (BADR).
In an asset sale, the buyer purchases specific assets of the business — equipment, goodwill, stock, contracts — but not the company entity itself. Buyers sometimes prefer this because they can pick what they want and leave liabilities behind.
The tax treatment differs significantly between the two structures, so take advice before agreeing which route to take.
Read more:Share sale vs asset sale UK
Business Asset Disposal Relief (BADR)
Business Asset Disposal Relief may reduce the Capital Gains Tax rate on qualifying business disposals, but the rate has changed in recent years. According to GOV.UK, the BADR rate for qualifying disposals is:
18% for disposals from 6 April 2026
14% for disposals between 6 April 2025 and 5 April 2026
10% for disposals on or before 5 April 2025
The relief is subject to conditions including share ownership thresholds, length of employment or directorship, and a lifetime limit. Do not assume you qualify — speak to a tax adviser before agreeing deal terms, completion date or sale structure.
VAT and TOGC
If the sale is structured as a transfer of a business as a going concern, known as a TOGC, the VAT treatment may differ from a normal asset sale. HMRC VAT Notice 700/9 explains when a transfer may be treated as a TOGC and how VAT should be handled in different circumstances. This should be checked by an accountant or VAT adviser before completion — the conditions are specific and both parties need to handle it correctly.

Warranties, indemnities and non-competes
The sale and purchase agreement (SPA or APA) will include warranties — statements you make about the business being true. If a warranty proves false, the buyer may be able to claim compensation. Read these carefully with your solicitor.
You will almost certainly also be asked to sign a non-compete clause — an agreement that you will not start or join a competing business for a defined period (typically two to three years) within a defined geography.

Staff and TUPE
If the business has employees, TUPE may apply when the business changes owner. TUPE can protect employees' rights and may affect what information must be shared before completion, what transfers to the buyer and how staff consultation is handled. The rules depend on the structure of the sale and the nature of the business. Take employment-law advice before communicating with staff or agreeing completion terms.

Step 9: Complete the deal and hand over properly
Completion day is when the legal documents are signed, money changes hands and ownership transfers. For most small business sales, this happens in a single day — though the preparation in the weeks before is significant.
What happens at completion
The sale and purchase agreement is signed by both parties
The buyer's funds are transferred (usually via solicitor accounts)
Ownership of shares or assets transfers legally
Lease assignments, if applicable, are completed
Bank mandates, supplier accounts, website access and systems logins are transferred
Staff are formally notified of the new owner
The handover period
Most sale agreements include a handover period during which the seller remains available to support the new owner. This typically runs from one to three months and covers:
Introductions to key customers and suppliers
Explaining systems, processes and procedures
Answering operational questions
Supporting the buyer during the transition
Take this seriously. A smooth handover protects your reputation, reduces the risk of post-completion warranty claims, and gives the business the best chance of succeeding under new ownership.

FAQs
How long does it take to sell a business in the UK?
Most small business sales take between three and twelve months from listing to completion. The biggest variables are how prepared the seller is, how quickly a suitable buyer is found, and how smoothly due diligence goes. Sales that fall through — often at due diligence stage — and have to restart add significant time.
Read more:How long does it take to sell a business?
Do I need a business broker?
Not necessarily. Many business owners sell successfully through a marketplace like Buy a Business Ltd without a broker, keeping full control of the process and saving on fees. A broker adds most value when the business is complex, valued above £500k–£1m, or when the seller has no experience of the sale process and wants someone to manage it entirely.

Can I sell a business that is not making a profit?
Yes, though it is harder. Asset-rich businesses, businesses with strong revenue and temporary profit issues, businesses with intellectual property, or businesses in sectors with high buyer demand can still sell. You need to be realistic about price and honest about the situation.
Read more:Can I sell a business that is not making a profit?
What happens to my staff when I sell?
TUPE regulations mean staff transfer to the new owner on their existing terms and conditions. You have a legal duty to inform — and in some cases consult — employees before completion. Your solicitor will advise on the specific obligations.
Should I tell my staff I am selling?
Most sellers keep it confidential until completion or very close to it. The risk of telling staff too early is that key people leave, which damages the business and the sale. Work with your solicitor and adviser on timing.
Can this guide replace professional advice?
No. This guide is for general preparation and education. Buying or selling a business involves legal, tax and financial decisions that require qualified professional advice specific to your situation.
Key takeaways
Get the business genuinely ready before you list — messy businesses sell for less and fall through more often.
Prepare your financial story thoroughly, including adjusted EBITDA and a clean add-back schedule.
Price realistically — overpricing is the most common reason businesses fail to sell.
Protect confidentiality with staged disclosure and NDAs before sharing sensitive information.
Screen buyers early — ask about funding, motivation and experience before opening the books.
Understand deal structure — price, earn-outs, deferred consideration and working capital adjustments all affect what you actually receive.
Get tax advice before agreeing terms — Business Asset Disposal Relief may reduce your CGT rate if you qualify, but the rate changed in April 2026. Confirm your position with a tax adviser before you agree completion terms.
Use a solicitor for the SPA, warranties and TUPE — do not try to handle legal documents yourself.
Plan the handover — a good handover protects your reputation and reduces the risk of post-completion claims.
