Buying or Selling a Business (Mergers and Acquisitions)

Buying or selling a company is usually the biggest transaction of an owner's life. We run the legal process end to end, protect you on the terms that matter and keep the deal moving to completion.

Deal sizeOwner-managed businesses and SME transactions, typically £250,000 to £20 million
TimescaleUsually 8 to 16 weeks from heads of terms to completion
Our feeFixed or capped fees agreed on the heads of terms

Share purchase or asset purchase

The first decision shapes everything else. In a share purchase, the buyer acquires the company itself with all its history, contracts, employees and liabilities; the seller receives a clean exit and, often, favourable tax treatment. In an asset purchase, the buyer picks the assets and contracts it wants and leaves the rest behind, but must transfer each contract, property and licence individually and take on the employees under TUPE. We advise on the structure with your accountants, taking into account tax, liabilities, licences (including any sponsor licence, which does not transfer automatically on a change of ownership) and the counterparty's expectations.

The process

  1. Heads of terms and confidentiality

    We draft or review the heads of terms to fix price, structure, exclusivity and timetable, and the NDA that protects the seller's information.

  2. Due diligence

    For buyers, legal due diligence on the company's contracts, employees, property, IP, disputes, data protection, immigration compliance and corporate records, reported in a form that focuses on the issues that affect price and risk. For sellers, we prepare the data room and manage responses.

  3. Sale and purchase agreement

    Drafting and negotiating the SPA or APA: price mechanics (completion accounts, locked box, earn-outs, retentions), warranties, tax covenant, indemnities, restrictive covenants and limitations on the seller's liability. The seller's disclosure letter qualifies the warranties and is as important as the agreement itself.

  4. Completion and after

    Board approvals, stock transfer forms and stamp duty (0.5% on share purchases above £1,000), Companies House filings, TUPE consultation, novation of contracts and release of security, followed by any post-completion adjustments.

Cross-border and international buyers

Overseas buyers of UK businesses face additional steps: National Security and Investment Act notifications in sensitive sectors, Companies House identity verification for new directors and PSCs, UK bank account and funding arrangements, and immigration planning for owners or managers who will run the business from the UK. Our combined commercial and immigration team handles these alongside the transaction so that the business can operate on day one after completion.

Frequently asked questions

How much does it cost to buy or sell a business?

We agree a fixed or capped fee once the heads of terms are settled, based on the deal size, structure and complexity. Buyers should also budget for due diligence and any accountancy and tax advice; sellers for preparing the disclosure and data room.

What are warranties and indemnities?

Warranties are statements of fact about the business given by the seller; if untrue, the buyer can claim for the loss in value. Indemnities are promises to reimburse the buyer pound-for-pound for specific identified risks, such as a known dispute or tax liability. Sellers limit their exposure through the disclosure letter, caps and time limits.

Do employees transfer with the business?

In a share purchase the employer does not change, so nothing happens to employees. In an asset purchase, TUPE transfers employees to the buyer on their existing terms, with information and consultation obligations on both sides.

How long does a business sale take?

Typically 8 to 16 weeks from heads of terms, depending on the depth of due diligence, financing and any third-party consents (landlords, key customers, regulators).
