Selling a Business in the UK: The Key Legal Stages

Selling your business is a major decision. Getting the process right requires careful planning, the right professional team, and a clear understanding of what lies ahead.

Understanding the legal process can help you prepare for a successful sale and avoid unnecessary complications along the way. From preparing your business for potential buyers to negotiating the sale agreement and transferring ownership, there are several important steps that come up when selling a business.

In this guide, we explain the key legal stages of selling a business in the UK, what to expect, and how to protect your interests throughout the process.

Preparing Your Business for Sale

Before putting your business on the market, it’s important to make sure everything is in order. Taking the time to prepare can make your business more attractive to potential buyers, reduce delays and help you achieve a better outcome.

Start by reviewing your financial records, contracts and any outstanding legal matters. Buyers will want a clear picture of how your business operates, including its financial performance, assets and potential liabilities.

Some of the key areas to consider include:

• Financial records: Ensure your accounts, tax returns, and financial information are accurate and up to date.
   
• Contracts and agreements: Review existing arrangements with customers, suppliers, employees and landlords.
   
• Intellectual property: Confirm that key assets, such as trademarks, domain names, and other intellectual property, are properly owned and documented.
   
• Outstanding disputes: Identify any ongoing legal issues or potential claims that could affect the sale.
   
• Business assets: Establish what is included in the sale, from equipment and stock to goodwill and customer relationships.

Addressing potential problems early can help prevent unexpected issues arising when a buyer begins their own checks.

Share Sale or Asset Sale: What’s the Difference?

One of the first decisions you’ll need to make is how your business will be sold. If you operate through a limited company, you generally have two main options: a share sale or an asset sale.

Share Sale

In a share sale, the buyer purchases shares in your company and takes ownership of the company itself.

The business continues to operate through the same legal entity, meaning its existing assets, contracts and liabilities generally remain with the company.

This can provide continuity for the business, although buyers will usually carry out detailed checks to understand the liabilities they are taking on.

Asset Sale

An asset sale involves selling specific parts of the business rather than the company itself.

This could include equipment, stock, property, intellectual property, goodwill and customer contracts.

The buyer and seller agree which assets and liabilities will transfer. However, certain obligations, particularly those relating to employees, may transfer automatically under the law.

If you’re operating as a sole trader or through an unincorporated partnership, the sale will generally involve transferring business assets rather than company shares.

Which option is best?

The right sale structure will depend on your circumstances, including the nature of your business, the buyer’s requirements and the potential tax implications.

Getting legal and financial advice at this stage is important, as the structure of the transaction can affect both the amount you receive and your responsibilities after the sale.

Understanding the Tax Implications

Selling a business can have significant tax consequences, so it’s worth considering these well before entering into negotiations.

Depending on your circumstances, you may qualify for tax relief, which can reduce the Capital Gains Tax payable on qualifying business disposals.

Your accountant or tax adviser can help you understand the potential tax liabilities and how the proposed sale structure could affect the proceeds you receive.

Agreeing the Terms of the Sale

Once you’ve found a potential buyer, the next step is usually to agree the main terms of the proposed transaction.

Before sharing commercially sensitive information, it’s sensible to put a Non-Disclosure Agreement (NDA) in place. This helps protect confidential information about your business during negotiations.

You may then agree on a document known as Heads of Terms, sometimes called a Letter of Intent.

This outlines the key points of the proposed sale, including:

• The agreed purchase price and payment arrangements.
• Whether the transaction will be a share sale or asset sale.
• Any conditions that must be satisfied before completion.
• The proposed timetable.
• Any arrangements for your involvement after the sale.

Although most Heads of Terms are not legally binding, certain provisions, such as confidentiality and exclusivity clauses, can be.

An exclusivity clause may prevent you from negotiating with other potential buyers for an agreed period, so it’s important to understand what you’re committing to before signing.

What Happens During Due Diligence?

Due diligence is the process through which a buyer investigates your business before committing to the purchase.

Their solicitors, accountants and other professional advisers will review relevant information to identify potential risks and confirm that the business is as represented.

This can involve examining financial accounts, contracts, employee information, property arrangements, regulatory compliance and any existing legal disputes.

You’ll usually be asked to provide documents through a secure online data room, allowing the buyer’s advisers to review the information and raise questions.

Your solicitor will help coordinate responses to legal enquiries and advise you on any concerns raised during the process.  We can provide you with a secure online data room as part of our service.

Being organised can make a real difference. Accurate, accessible records from the outset can keep the transaction moving and reduce the risk of delays or last-minute negotiations.

Negotiating the Business Sale Agreement

As due diligence progresses, the legal teams will negotiate the agreement that sets out the transaction terms.

Depending on the structure, this will usually be a Share Purchase Agreement (SPA) or an Asset Purchase Agreement (APA).

The agreement covers key matters such as the purchase price, payment arrangements, each party's responsibilities, and the protections available if something goes wrong.

Sellers need to pay particular attention to several areas, including:

Warranties and Indemnities

Warranties are statements you make about your business, covering matters such as its finances, assets, contracts and legal compliance.

If a warranty proves incorrect, the buyer may be able to bring a claim against you.

Indemnities provide protection against particular risks or liabilities identified during the transaction and can create more direct financial obligations.

Your solicitor will help negotiate these provisions and, where appropriate, prepare a Disclosure Letter identifying exceptions to the warranties. Proper disclosure can help limit your post-completion exposure to claims.

Deferred Payments and Earn-Outs

Not every business sale involves receiving the full purchase price on completion.

Some transactions include deferred payments, where part of the price is paid at a later date, or earn-outs, where additional payments depend on the business meeting agreed performance targets.

These arrangements can help buyers and sellers reach an agreement on price, but they also introduce risks.

For example, if part of your payment depends on future profits, you’ll want to understand how those profits will be calculated and what influence you’ll have over the business after the sale.

Clear contractual terms are essential to reducing the risk of disagreements later.

Restrictive Covenants

Buyers will often want reassurance that you won’t immediately establish a competing business or approach the customers and employees of the business you’ve sold.

This is where restrictive covenants come in.

These provisions can limit certain activities for a specified period following completion. However, restrictions need to be carefully drafted and reasonable to be enforceable.

Your solicitor can help negotiate terms that protect the buyer’s legitimate interests without placing unnecessary restrictions on your future plans.

What Happens to Employees When You Sell a Business?

If your business employs staff, you’ll need to consider how the sale could affect them.

In many asset sales involving the transfer of an ongoing business, the Transfer of Undertakings (Protection of Employment) Regulations 2006, commonly known as TUPE, may apply.

Where TUPE applies, employees generally transfer automatically to the new employer, retaining their existing employment terms and continuity of service.

You also have legal obligations to inform affected employees or their representatives about the transfer and, where relevant, consult on proposed changes.

It’s important to note that TUPE does not normally apply to a straightforward share sale, as the employees continue to work for the same company, even though its ownership changes.

Employment matters can be among the most sensitive aspects of selling a business. Taking advice early can help you understand your responsibilities, communicate appropriately with staff and minimise disruption.

Completing the Sale and Transferring Ownership

Completion is the point at which the sale is finalised and ownership transfers to the buyer.

Depending on the transaction, this usually involves signing the final legal documents, transferring the shares or agreed assets, and making the required payments.

There may also be additional steps to complete, such as:

• Transferring or assigning property leases, where required.
• Arranging the transfer of intellectual property and other business assets.
• Obtaining necessary third-party consents.
• Updating company records and making relevant filings with Companies House.
• Handing over important business information and documentation.

Your solicitor will coordinate the legal requirements and work with the other parties to ensure completion takes place as agreed.

What Happens After You’ve Sold Your Business?

Although completion marks the end of the sale itself, you may still have responsibilities afterwards.

For example, you might agree to stay involved for a short period to help the new owners understand the business, introduce them to key customers or support the handover.

You’ll also need to comply with any ongoing obligations in the sale agreement, including restrictive covenants, deferred payment arrangements and contractual commitments.

Understanding these responsibilities before completion will help you move on to your next chapter with greater confidence.

How Long Does It Take to Sell a Business?

There is no fixed timescale for selling a business in the UK.

Some straightforward transactions can be completed within a few months, while more complex sales may take considerably longer.

The timeframe depends on several factors, including the business's size and structure, the buyer’s due diligence requirements, the complexity of the negotiations, and whether any third-party approvals are needed.

Preparing your documents early, addressing potential legal issues and having experienced professional advisers to project manage can all help keep the process on track.
