Share Purchase or Asset Purchase? How to Buy a UK Business the Right Way

You’ve found a business you want to buy. Maybe it’s a shop, a small manufacturer, a service company — something with customers, a track record, and a seller who’s ready to move on. You’ve agreed a price in principle. And then someone — a solicitor, an accountant, a well-meaning friend who’s done this before — asks you a question that stops you cold: “Are you buying the shares, or the assets?”

If you’ve never bought a UK business before, this can feel like a strange thing to have to decide. Surely buying a business just means… buying the business? In English law, the choice between a share purchase or asset purchase isn’t a formality — it changes almost everything about what you’re taking on, what protection you have, and what can go wrong afterwards.

What’s the Difference Between a Share Purchase and an Asset Purchase in the UK?

In England and Wales, there are two fundamentally different ways to buy a business, and they are not interchangeable.

A share purchase means you buy the shares of the limited company itself. The company — with its name, its contracts, its bank accounts, its history, its debts, and anything it has ever done or agreed to — continues to exist exactly as it did before. You haven’t bought “the business” in a loose sense; you’ve bought the legal entity that owns it, lock, stock, and barrel.

An asset purchase means you buy specific things the business owns — its equipment, its stock, its premises, its customer contracts, its brand and goodwill — without buying the company itself. The seller’s company still exists afterwards; it simply no longer owns those assets. You build a new structure and pick, deliberately, what goes into it.

This distinction has no clean equivalent in many commercial traditions, where “buying a business” is usually understood as one single, relationship-based handover. In English law, it is a formal legal choice with real consequences, and it is made early — often before you have even agreed a price.

What Am I Actually Taking On in Each Case?

This is where the choice starts to matter in practical terms.

With a share purchase, you inherit the company exactly as it stands — including things you cannot see on a balance sheet. Unpaid tax liabilities, an ongoing dispute with a former employee, a contract with an onerous termination clause, an environmental issue from years ago: all of it comes with the company, because the company itself hasn’t changed hands, only who owns it has.

With an asset purchase, you choose what you’re buying. You can take the equipment and the customer list without taking on the seller’s old supplier disputes or historic tax position, because those liabilities generally stay with the seller’s company, not with you.

This makes an asset purchase sound safer — and often it is — but it isn’t automatically the right answer. Asset purchases can be more complicated to execute (each asset, contract, and licence may need to be individually assigned or re-negotiated with third parties), and certain valuable things — like a trading history, an existing VAT registration, or continuity of contracts that specifically require the company to remain unchanged — are easier to preserve through a share purchase.

What Does English Law Actually Require?

A few specific rules shape this decision, and it’s worth understanding them in plain terms before you go further.

Employees. If you buy assets rather than shares, the employees working in that part of the business will usually transfer to you automatically under the Transfer of Undertakings (Protection of Employment) Regulations 2006, commonly known as TUPE. This means you inherit their existing employment terms, continuity of service, and — in many cases — certain protections against dismissal connected to the transfer. Many first-time buyers assume that buying “the assets” but not “the company” means starting with a clean slate on staffing. It usually doesn’t.

Company law formalities. A share purchase is governed largely by the Companies Act 2006 and requires updating the company’s statutory registers, notifying Companies House of the change in ownership, and — critically — obtaining proper warranties and indemnities from the seller in the share purchase agreement, since you are taking the company as it is, including its history.

Contracts and consents. In an asset purchase, contracts don’t automatically transfer with the assets — many will need the other party’s consent to be assigned to you, and some contracts include clauses that let the counterparty walk away entirely if there’s a change of ownership. This needs to be checked contract by contract, not assumed.

What Mistakes Do Buyers Usually Make?

The most common mistake is deciding the deal before deciding the structure — agreeing a price and a handshake, then only later discovering that the deal has to be unwound and rebuilt around a share or asset purchase agreement, often at extra cost and with the seller’s goodwill wearing thin.

The second is assuming that because no formal contract has been signed, nothing is legally binding yet. Under English law, agreement can be reached — and obligations can arise — well before a written contract exists, depending on what was said and done. “We shook hands, nothing’s signed, so we can still walk away” is not a safe assumption to build a transaction on.

The third is underestimating due diligence. Buyers who are used to a more relationship-based way of doing business sometimes treat due diligence — checking the company’s contracts, debts, disputes, and compliance history — as a formality or even an insult to the seller’s word. In a share purchase especially, it is the only real protection you have against inheriting problems you can’t see.

Do I Actually Need a Solicitor for This?

If you are buying assets worth a modest amount, with no employees transferring and no complex contracts involved, it is possible to manage parts of the process yourself with a straightforward asset purchase agreement.

But if you are buying shares, if employees are involved, or if the business has contracts, property, intellectual property, or debts of any complexity, professional advice isn’t optional — it’s the difference between knowing exactly what you own on day one and finding out the hard way. A solicitor’s job here isn’t to make the deal harder; it’s to make sure the price you agreed is the price you’re actually getting, with no unwelcome surprises buried in the structure.

Whichever structure fits your situation, the decision is worth making deliberately, not by default.
