Tips for Businesses
Decide early whether you want a clean exit or to retain part of the business. Map your key contracts for assignment and change-of-control clauses, check whether TUPE will move staff, and take tax advice before you agree the structure.
When selling a UK business, you can structure the deal as an asset sale or a share sale. In an asset sale, the buyer takes specific assets and only the liabilities both sides agree to transfer, while the selling company stays in place. In a share sale, the buyer acquires the shares in the company itself, so it inherits all assets and liabilities, known and unknown. The choice affects liability, employees under TUPE, contracts and tax. Buyers often prefer asset sales to limit risk. Sellers often prefer share sales for a cleaner exit. The right structure depends on the business, the risk each side accepts and their bargaining position. This article explains how each route works under UK law, and where the risks and responsibilities sit for buyers and sellers.
What Is an Asset Sale?
An asset sale means the buyer purchases specific assets of the business rather than the company itself. The selling entity stays in place. It keeps any assets and liabilities that are not expressly transferred as part of the sale.
Assets commonly included in an asset sale are:
- equipment and machinery
- stock and work in progress
- intellectual property such as trademarks, patents and goodwill
- customer databases and business systems
The Transfer of Undertakings (Protection of Employment) Regulations 2006, known as TUPE, is one of the biggest issues in an asset sale. Where TUPE applies, employees assigned to the business transfer automatically to the buyer, along with their existing rights and obligations. This limits the buyer’s ability to pick assets without taking on staff.
Contracts add further complexity. Many commercial agreements restrict assignment, so you may need third-party consent before a contract can transfer. Property, licences and intellectual property rights often need formal documentation to transfer validly.
What Is a Share Sale?
In a share sale, the buyer acquires the shares in the company that owns the business. The legal entity itself does not change. Control of the company passes to the buyer.
As a result:
- all assets remain owned by the company
- all liabilities, known and unknown, remain with the company
- employees keep working for the same employer, the company
This structure gives continuity. The business runs the same way after completion, simply under new ownership.
Because the buyer takes the company as is, they also inherit its history. That includes contractual obligations, regulatory compliance issues and potential claims arising from past conduct. Buyers usually run detailed legal due diligence for this reason. They also seek warranties and indemnities in the share purchase agreement to protect against unforeseen risks.

Risk and Liability Allocation
How risk is allocated is a major difference between the two routes.
In an asset sale, buyers can limit their exposure by choosing which assets and liabilities to acquire. That appeals where the business has legacy issues, or where the buyer only wants part of the operation.
In a share sale, buyers take on the company’s entire legal history. Contractual protections reduce exposure but cannot remove risk entirely.
Warranties, Indemnities and Disclosure
Warranties and indemnities decide who carries the risk once the deal completes. They matter most in a share sale, where the buyer inherits the company’s full history.
A warranty is a statement of fact about the business, given by the seller in the sale agreement. If a warranty turns out to be untrue and the buyer suffers loss, the buyer can claim damages. Common warranties cover accounts, tax, employees, litigation, contracts and intellectual property.
An indemnity is a promise to reimburse the buyer, pound for pound, for a specific identified risk. Buyers ask for indemnities where due diligence uncovers a known problem, such as a live dispute or a tax exposure.
In an asset sale, warranty cover is usually narrower, because the buyer takes only named assets and agreed liabilities. Either way, protection depends on the drafting, so take advice before signing.
Employees and TUPE
Employees are a central consideration in both structures under UK law.
In an asset sale, TUPE will usually apply if the business is an economic entity that keeps its identity after the sale. That means:
- employees transfer automatically to the buyer
- their terms and conditions stay the same
- dismissals connected to the transfer are likely to be unfair
In a share sale, TUPE does not apply. The employer stays the same legal entity, so employees see no change of employer. There may still be changes at management or strategic level after completion.
Contracts, Property and Licences
Asset sales often need a detailed review of every contract and asset, to work out how and whether each can transfer. This can include:
- landlord consent for lease assignments
- counterparty approval for commercial contracts
- re-registration of intellectual property
Share sales usually avoid these steps, because contracts and property stay with the company. Watch for change-of-control provisions though. Some agreements let a counterparty terminate or renegotiate after a share sale, or require their consent for the change in control to happen. Review these clauses carefully.

the documents you need to make an effective sale.
Complexity and Transaction Timelines
Asset sales tend to be more administratively intensive. Each asset must be identified, valued and transferred on its own, which adds documentation and negotiation time.
Share sales are usually more streamlined, especially where the company already runs an established business with contracts, employees and systems in place. That makes share sales attractive where speed and continuity matter.
Which Route Is Right for Your Business?
There is no universally better option. The right structure depends on:
- the nature and scale of the business
- the level of risk the buyer will accept
- whether the seller wants a complete break or is keeping part of the business
- practical factors such as employees, contracts and property

Frequently Asked Questions
Is a share sale more tax-efficient than an asset sale?
Historically, a share sale has often been more tax-efficient than an asset sale, though the position depends on the specific business and reliefs available. Tax treatment frequently drives the choice of structure, so take specialist tax advice before you decide.
Do all shareholders need to approve a share sale?
A share sale generally requires all the shareholders selling their shares to agree to the transaction. This can make a share sale harder to complete where ownership is split, or where a minority shareholder resists the deal.
Can I sell only part of my business?
Yes. An asset sale lets you sell part of a business by transferring selected assets while keeping the rest. This suits owners who want to exit one operation or product line but continue running the remainder of the company.
What are warranties and indemnities in a share sale?
Warranties are statements of fact the seller gives about the business. Indemnities are promises to reimburse the buyer for specific identified risks. Together they allocate risk between buyer and seller and give the buyer recourse if problems surface after completion.
