Selling a business you have built over years is one of the largest financial decisions you will make. Whether you are retiring, starting something new, or responding to a direct approach, the business transfer process UK owners must follow has specific legal, tax, and regulatory steps. Get them wrong and you can lose value, face HMRC penalties, or remain tied to liabilities after the sale. This guide sets out what women founders need to know in 2026, from choosing a sale structure to completing the deal.

The 2019 Alison Rose Review of Female Entrepreneurship, commissioned by HM Treasury, estimated that up to £250 billion could be added to the UK economy if women started and scaled businesses at the same rate as men. Exiting well is part of that scaling story. You can find the latest figures on women in business in the UK.

Start with a Clear Exit Goal

Before you speak to a broker or buyer, decide what you want from the sale. Are you looking for the highest cash price, a phased handover, or continued involvement as a consultant? Do you want to protect jobs, keep the brand name in the local area, or retain a minority stake? Your goal shapes every later decision, from the sale structure to the warranties you give.

Be honest about timing. A rushed sale rarely achieves the best price. Start preparing early so you can clean up accounts, resolve disputes, and gather the documents a buyer will request.

Map Out the Business Transfer Process UK

The business transfer process UK sellers follow usually has six stages:

1. Valuation and preparation: establish a realistic price range and fix problems that reduce value.
2. Marketing or direct approach: find buyers through brokers, networks, or targeted outreach.
3. Heads of terms: agree the headline price, structure, and conditions before full legal work begins.
4. Due diligence: the buyer examines your finances, contracts, employees, intellectual property, and compliance records.
5. Legal completion: sign the sale and purchase agreement, transfer funds, and update statutory records.
6. Post-completion: handle any earn-outs, restrictive covenants, or handover obligations.

Each stage has cost and risk. Skipping preparation to save time typically costs more at the negotiation table.

Choose the Right Sale Structure

Most UK small business sales are either a share sale or an asset sale.

In a share sale, you sell the company itself. The buyer takes the business with its contracts, employees, and liabilities intact. This is usually more tax-efficient for the seller because the gain is taxed as a capital gain, and you may qualify for Business Asset Disposal Relief.

In an asset sale, the buyer purchases specific assets such as stock, equipment, customer lists, and goodwill. They do not automatically take the company’s liabilities or employees, although the Transfer of Undertakings (Protection of Employment) Regulations 2006 may protect employees. Asset sales can suit buyers who want to avoid historical risks, but they can create a more complex tax position for the seller.

If you operate as a sole trader or partnership, you cannot sell shares. You can only sell assets. If you run a limited company, you have more options. Read our plain-English guide on what is a limited company if you are unsure which structure applies to you.

Get Your Business Ready for Due Diligence

Due diligence is where deals succeed or fail. A buyer will ask for at least three years of filed accounts, tax returns, employment contracts, supplier and customer agreements, leases, intellectual property registrations, and data protection records. If you are a limited company, make sure your Companies House identity verification is complete and your director and people with significant control records are accurate. From 2025, Companies House requires directors and people with significant control to verify their identity (Companies House, 2025), and errors on the public register can delay or derail a sale.

Resolve disputes, renew key contracts, and collect evidence of recurring revenue. If your business depends on a few large customers, a buyer will see concentration risk. If your contracts are informal, put them in writing. The cleaner your records, the stronger your negotiating position.

Understand the Tax Bill Before You Price the Deal

Tax can take a significant slice of your sale proceeds. For the 2026/27 tax year, HMRC sets the Capital Gains Tax annual exempt amount at £3,000 for individuals and charges Capital Gains Tax at 18% or 24% on most chargeable gains (HMRC, 2026/27). HMRC’s Business Asset Disposal Relief lets qualifying sellers pay 10% on lifetime gains up to £1 million, but strict conditions apply, including a minimum two-year ownership period and being an officer or employee of the trading company.

If you sell assets rather than shares, you may also face Corporation Tax on gains inside the company, plus Income Tax or Dividend Tax when you extract the proceeds. Early advice from a tax accountant is essential. Do not wait until you have a buyer; structure decisions made months earlier can change the final tax bill.

You can check the latest thresholds and conditions on gov.uk’s Business Asset Disposal Relief page.

Find and Vet Buyers Carefully

You can find buyers through business transfer agents, professional networks, industry contacts, or direct approaches. A good broker will value the business confidentially, prepare an information memorandum, and screen buyers before they see sensitive details. If you use a broker, check their membership of a recognised body, their recent sales in your sector, and their fee structure. Fees vary and usually include a retainer plus a success fee, so compare terms before signing.

Before sharing sensitive information, ask potential buyers to sign a non-disclosure agreement. Check their funding source. A buyer who cannot prove finance is not a serious buyer, however enthusiastic they appear.

Negotiate Heads of Terms

Heads of terms set out the skeleton of the deal: price, payment structure, completion date, exclusions, and any conditions. They are usually not legally binding on the main commercial points, but they create moral commitment and reduce wasted legal fees. Agree whether the price is fixed, subject to completion accounts, or includes an earn-out tied to future performance.

Be specific about what is included and excluded. Are you keeping the company car, the website domain, the social media accounts, or the office lease? Ambiguity here causes disputes later.

Complete the Legal Transfer

At completion, you will sign a sale and purchase agreement, possibly a tax deed, employment-related documents, and any restrictive covenants. Your solicitor should handle the transfer of funds through a secure client account, update Companies House filings, and notify HMRC if needed. Do not hand over control of bank accounts, passwords, or customer data until the purchase funds have cleared.

After completion, file any required updates with Companies House, inform employees in line with TUPE or consultation rules, and keep a full record of the transaction for at least six years in case of HMRC enquiries.

Take These Practical Action Steps

• Define your personal and financial goals for the sale.
• Decide whether a share sale or asset sale suits your business.
• Clean up accounts, contracts, and statutory records, including Companies House identity verification.
• Speak to a tax accountant about Business Asset Disposal Relief and Capital Gains Tax before you market the business.
• Shortlist brokers or buyers and secure non-disclosure agreements before sharing sensitive information.
• Agree heads of terms before incurring full legal costs.
• Use a solicitor to handle completion funds and statutory filings.

The business transfer process UK owners face is complex, but it is navigable with the right preparation. Start planning early, get professional advice, and treat the sale as a project in its own right. Done well, it can turn years of work into the financial outcome you deserve.
