Key takeaways

• Start planning your business sale 12 to 24 months before your intended exit date to meet tax relief requirements like Business Asset Disposal Relief and avoid rushed decisions that could reduce your sale price.
• Prepare comprehensive documentation including three years of financial statements, key contracts with customers and suppliers, and detailed process manuals to speed up due diligence and build buyer confidence.
• Get your business professionally valued by an accountant or broker using asset-based, earnings-based, or market-based methods to establish a realistic asking price and strengthen your negotiating position.
• Consider selling to people you already know first, such as employees, family members, or industry contacts, as these sales typically complete faster than finding external buyers through brokers or online marketplaces.

How to sell a business

Selling a business means transferring ownership of your company to a buyer in exchange for payment. The process typically takes 6 to 12 months and involves preparing documents, getting your business valued based on multiples paid for UK private businesses, finding buyers, negotiating terms, and completing the legal transfer.

Whether you're retiring, changing careers, or pursuing new opportunities, following a structured approach helps you achieve the best price and smoothest transition.

Make a plan to sell your business

Plan your business sale 12 to 24 months before your intended exit date. This timeline matters because certain tax reliefs, such as Business Asset Disposal Relief, require you to meet qualifying conditions for a period of two years.

Starting early provides three key advantages:

• Avoid rushed decisions: You'll have time to find the right buyer at the right price.
• Capture unexpected opportunities: You can respond quickly to unsolicited offers.
• Improve business value: The preparation process reveals areas for improvement that boost sale price.

Work with your accountant, bookkeeper or tax adviser to get your documents in order and make the sale tax efficient. If you need an accountant or bookkeeper, find one in the Xero adviser directory.

Choose your exit route

Before you look for a buyer, decide how you want to sell. In the UK, there are two main ways to structure a sale: a share sale or an asset sale.

A share sale transfers ownership of your entire company, including all its assets and liabilities. An asset sale lets you sell specific parts of the business, like equipment or customer lists, while you keep the company structure.

You can also consider selling to family members, your management team, or another business in your industry. Each option has different tax and legal implications, so it's a good idea to discuss them with your accountant.

Prepare your documents

Preparing documents means gathering the records buyers need to evaluate your business. This typically takes three to six months and covers three critical areas: financial statements, contracts, and internal processes.

Buyers expect to see at least three years of comprehensive business records. Having these ready speeds up due diligence and builds buyer confidence.

Financial statements

Buyers will want to see three years of financial records:

• Profit and loss statements: Show your business makes money
• Balance sheets: Show the value of your equipment, property, and inventory against your debts
• Cash flow statements: Confirm your business generates cash from operations

Supplier agreements and customer contracts

Renew key agreements with customers and suppliers, especially those critical to your business. Secure written contracts with major clients and suppliers.

Internal processes

Document your business processes. Write down how your business operates, who is responsible for each task, the order of operations, and the systems you use. Create a manual to help a new owner run the business smoothly. Ask employees to document the parts relevant to their roles.

Get your business valued

Valuing your business determines what your company is worth to potential buyers. Having your business professionally valued gives you a realistic asking price and strengthens your negotiating position.

You have two main options for getting your business valued:

• Accountant: Useful for sales to known buyers like employees or family members
• Broker: Helpful when you need to find external buyers, as brokers also handle marketing

Three methods to value a business

Business valuation methods fall into three categories:

• Asset-based valuation: Calculates total assets minus liabilities from your balance sheet and suits liquidation scenarios
• Earnings-based valuation: Values the business based on profit and cash generation history and requires three years of solid financial records
• Market-based valuation: Multiplies revenue by industry-standard multiples and suits sectors with established benchmarks. According to the ICAEW, there are industry-specific customs where valuation focuses on recurring income; for example, dry cleaning businesses are valued on annual gross sales, while trust companies are valued on gross fees.

Choose your professional advisers

Selling a business is complex, and you don't have to do it alone. Building a team of professional advisers can help you get the best outcome.

An accountant is key for valuing your business, organising your financials, and planning for tax. A solicitor will handle the legal paperwork, like the sale agreement.

You might also work with a business broker, who can help find potential buyers and negotiate offers. Getting the right advice early on makes the process smoother and more secure.

Understand tax implications of selling your business

Capital Gains Tax (CGT) applies to the profit you make when selling your business in the UK. The amount you pay depends on the sale price minus your original investment, adjusted for your income tax band.

Business Asset Disposal Relief (formerly Entrepreneurs' Relief) can reduce your tax bill significantly. Qualifying gains are taxed at 10% up to a lifetime limit of £1 million.

Speak to your accountant or tax adviser early. They can help you structure the sale to minimise tax and ensure you meet the qualifying conditions for available reliefs.

Find a buyer

Finding a buyer starts with people you already know, expands to people referred by your professional network, and then moves to external services for wider reach.

Internal buyers:

• Family members or employees: Bring existing relationships and business knowledge
• Suppliers, customers, or competitors: Offer industry familiarity and strategic fit

Network referrals:

• Professional advisers: Connect you with entrepreneur networks through accountants, bankers, and lawyers
• Business consultants: Provide industry connections and qualified prospects

External buyer services:

• Business brokers: Market your business through publications and buyer databases
• Online marketplaces: Give wider exposure to buyers you don't already know

Negotiate the sale and manage due diligence

Once you have interested buyers and have shared business details, ask them to submit offers. If you have several buyers, set a clear deadline for offers.

Offers should:

• State the price: Specify the total amount and any price adjustments
• Set conditions before closing: Identify what must happen before the deal completes and set a target date
• Note conditions after closing: Outline any requirements that apply after completion
• Detail payment terms: Specify how and when the money will be paid
• Define transition support: Explain any training or handover they need from you and for how long

The offer may also suggest a time frame for due diligence, during which the buyer will run their own checks on the business to verify your claims.

Some buyers may ask for exclusivity, meaning you negotiate only with them for a set period. Others may include earn-out clauses, where part of the price depends on the business performing well after the sale.

Business brokers can help you decide which offers and conditions to accept.

Support the due diligence process

Due diligence is when the buyer investigates your business to verify your claims before completing the purchase. This process typically takes four to 12 weeks after accepting a conditional offer.

Buyers will examine three key areas:

Legal due diligence

Buyers will review your legal position, including:

• pending or ongoing legal action against the business
• intellectual property such as copyright, trademarks, and patents
• service agreements and their transferability

Financial due diligence

Buyers will examine your financial records to verify accuracy:

• review financial statements against supporting documents
• request additional reports and forecasts or create their own
• check the business credit profile
• review tax history and compliance

Commercial due diligence

Buyers will assess the wider business opportunity:

• review the market and growth potential
• analyse competitors and your competitive position
• evaluate your business model and strategies for continued profitability

How to speed up due diligence

Due diligence can take time. Speed up the process by:

• Preparing complete financial records: Have three years of statements ready to share
• Organising agreements: Gather all contracts, leases, and supplier terms in one place
• Documenting your business plan: Provide a written summary of operations and growth strategy
• Using accounting software: Generate reports quickly as buyers request them

Complete the sale and transfer ownership

After the sale, your work continues after the deal closes. Work with your accountant to complete these essential tasks:

• File final tax returns: Declare sale proceeds to HMRC and submit your final business tax return
• Close VAT accounts: Deregister for VAT with HMRC if applicable
• Update Companies House: Amend Articles of Association to reflect new ownership for limited companies
• Transfer licences and permits: Notify relevant authorities and transfer required registrations. For example, the Financial Conduct Authority (FCA) expects firms selling a client bank to notify the FCA via a SUP 15 notification if the sale could affect the firm's risk profile.

Set yourself up for a successful sale

Start preparing to sell your business 12 to 24 months before your planned exit. Give yourself time to organise financial records, secure key agreements, document processes, and update your business plan.

Break the work into manageable steps and ask employees or consultants for help. Talk to others who have sold a business for practical advice. Thorough preparation helps you achieve the best price and smoothest transition.

FAQs on selling a business

Selling your business raises a lot of questions. Here are answers to some of the most common ones.

How much can I sell a small business for?

The sale price depends on your business type, profitability, and market conditions. Common valuation methods include:

• a multiple of your annual profits
• total assets minus liabilities
• comparison with similar businesses that have sold recently

A professional valuer or broker can give you the most accurate estimate for your specific situation.

How much does it cost to sell a business in the UK?

Costs vary, but you should budget for professional fees. These can include fees for your accountant, solicitor, and any business broker you use. Broker fees are often a percentage of the final sale price, typically between 1% and 10%. Get clear quotes upfront so you can manage your budget.

What is the most tax efficient way to sell a business in the UK?

The most tax efficient method depends on your specific circumstances. Business Asset Disposal Relief can lower your Capital Gains Tax rate to 10% on qualifying gains. Structuring the sale as a share sale versus an asset sale also has different tax outcomes. Planning early with a tax adviser is the best way to ensure you make the most of available reliefs.

Do I pay tax if I sell my business?

Yes, you usually pay Capital Gains Tax on the profit from selling your business. The rate depends on your income tax band and total gains.

Business Asset Disposal Relief can reduce the rate to 10% on qualifying gains up to £1 million. Get professional tax advice early to understand your obligations and claim available reliefs.

What is the fastest way to sell a business?

Selling to someone you already know, such as an employee, family member, or competitor, is typically the fastest route. These sales can complete in three to six months compared to six to 12 months on the open market.

Regardless of the buyer, having your documents prepared and financials organised speeds up the process significantly, especially during due diligence.

When should I start preparing to sell my business?

Start planning 12 to 24 months before you intend to sell. This gives you time to organise financial records, secure key contracts, and document your processes.

The timeline also matters for tax. To claim Business Asset Disposal Relief, you must meet qualifying conditions for at least two years before the sale.

Do I need a business broker to sell my business?

A broker isn't essential, especially if you already have a buyer in mind. However, brokers can add value by:

• providing an independent valuation
• marketing your business confidentially to a wider network
• managing negotiations on your behalf
• helping you achieve a better price and terms

For most sales to unknown buyers, a broker's expertise typically justifies their fee of 1% to 10% of the sale price.
