Thinking about selling a limited company? Whether you’re planning an exit, merging with a competitor, or passing the reins to a new owner, the way you structure the deal can make a big difference to price, risk and tax.
The good news is that with the right prep, documents and approvals, you can complete a clean sale and protect yourself along the way. In this guide, we’ll break down how to sell a limited company in the UK, the key legal steps, and the contracts and compliance issues you shouldn’t overlook.
What Does “Selling A Limited Company” Actually Mean?
In the UK, there are two main ways to sell your business:
- Share sale – You (the shareholders) sell your shares in the limited company to the buyer. The company remains the same legal entity and keeps all assets, employees, contracts and liabilities. The buyer steps into your shoes as the new owner.
- Asset sale (business sale) – The company sells selected assets and business undertakings (for example, stock, equipment, IP, customer contracts, goodwill) to the buyer. The limited company itself is not sold; it may remain with you and can be wound up or repurposed afterwards.
Each route has different commercial, legal and tax implications. A share sale is often simpler for continuity (the company carries on with the same contracts, employees and licences), but buyers sometimes prefer an asset sale to “cherry pick” what they’re buying and leave unwanted liabilities behind.
At a high level, a share sale is documented by a Share Sale Agreement, while an asset sale is documented by a Business Sale Agreement. We’ll unpack the other essential documents shortly.
How To Sell A Limited Company: Step-By-Step
Every deal is different, but most small business sales follow a familiar path. Here’s a practical roadmap.
1) Get Sale-Ready
- Financial housekeeping – Clean, up-to-date accounts, management reports and tax filings build buyer confidence and speed up due diligence.
- Contract tidy-up – Locate key contracts, confirm assignment or change-of-control provisions, and renew anything critical that’s nearing expiry.
- IP and ownership checks – Make sure your brand, domains, software and other IP are actually owned by the company (not founders or contractors). If gaps exist, fix them now (for example, with an IP Assignment).
- People and policies – Ensure employment contracts, handbooks and policies are current and compliant. Resolve any pending disputes where possible.
2) Protect Confidential Information
Before you share financials, customer lists or trade secrets, ask the buyer to sign a Non-Disclosure Agreement (NDA). This sets boundaries around what they can do with your information and helps protect your position if the deal doesn’t proceed.
3) Agree Heads Of Terms
Heads of terms (also called a term sheet or letter of intent) outline the key commercial points: price, what’s included, completion conditions, target timeline and any exclusivity period. They’re usually not legally binding (except for confidentiality and exclusivity), but they set expectations and help your advisers focus on the right issues.
4) Due Diligence
Expect detailed questions about your financials, legal structure, contracts, licences, IP, HR and data protection. Being organised here not only keeps the momentum but can support a better price. A seller-side pack can streamline this process; for busy owners, a curated Legal Due Diligence Package can help you present documents clearly and address red flags early.
5) Choose Deal Structure: Share Sale Or Asset Sale
Work with your lawyer and tax adviser to decide which route best fits your goals and risk profile. Consider:
- Continuity – Share sales preserve contracts and licences. Asset sales may require assignments, novations and fresh registrations.
- Liabilities – Buyers can ringfence liabilities more easily in asset deals. Share buyers take the company “as is,” mitigated by warranties and indemnities.
- Tax – There can be differences in capital gains treatment for sellers and stamp duty/VAT consequences. Get tailored tax advice early.
6) Draft The Core Contracts
Your main transaction agreement will be either the Share Sale Agreement or the Business Sale Agreement. It will include the price mechanism (fixed price, completion accounts or locked box), warranties, indemnities, restrictive covenants (non-compete and non-solicit) and the list of conditions to completion.
7) Secure Approvals And Consents
- Internal approvals – Board and shareholder approvals (under the Companies Act 2006 and your Articles). Some sales require a special resolution.
- Third-party consents – Landlord, franchisor, suppliers, lenders or key customers. If you’re transferring a premises, you may need to consider assigning a lease.
- Regulatory – Sector-specific approvals or notifications where relevant (for example, FCA permissions or local authority licences).
8) Completion And Post-Completion
On completion day, money moves, documents are signed and dated, and ownership transfers. Use a tight checklist so nothing is missed – a structured Completion Checklist helps coordinate signatures, filings and handover items. After completion, you’ll typically handle company secretarial filings (such as Companies House updates), tax returns, and handover support under any agreed transition plan.
Key Legal Documents When Selling A Limited Company
Here are the usual suspects you’ll encounter. Not every deal needs every document, but this list will help you spot what’s missing.
- Non-Disclosure Agreement (NDA) – Keeps your confidential information protected during discussions and diligence. A tailored Non-Disclosure Agreement is essential before sharing data rooms.
- Heads Of Terms – Records core commercial terms, often including exclusivity and a target timetable.
- Share Sale Agreement – Used for a share sale. Covers price, completion mechanics, warranties and indemnities, restrictive covenants, tax covenants and limitations on seller liability. See our Share Sale Agreement.
- Business Sale Agreement – Used for an asset sale. Schedules list the assets, employees, contracts and IP being transferred; apportionments and VAT/TOGC treatment are addressed. Explore our Business Sale Agreement.
- Disclosure Letter – Your chance to qualify the warranties by disclosing known issues. Properly prepared disclosures are a key risk control for sellers.
- IP Assignment/Transfer Documents – Transfers trade marks, domains, software code or other IP to the buyer where required. Consider a formal IP Assignment to avoid ownership gaps.
- Data Sharing Agreement – If you need to share personal data during diligence or transfer customer databases at completion, a structured Data Sharing Agreement helps with UK GDPR and Data Protection Act 2018 compliance.
- Employment Transfer Documents – In an asset sale, employees will usually transfer automatically under TUPE (more on this below) with required information/consultation obligations.
- Assignment/Novation Agreements – Transfers customer and supplier contracts in an asset sale, where consent is needed.
- Board/Shareholder Resolutions – Approves the transaction under the Companies Act 2006 and your Articles; some actions may require a special resolution.
- Lease Assignment/Deed Of Surrender – For premises, you may need a landlord-approved assignment or a surrender; see our guide on assigning a lease.
Avoid generic templates – the warranties, caps, baskets, time limits and tax protections need careful tailoring to your deal. Getting these wrong can wipe out the commercial benefit of the sale.
Employment, Customers, Data And Other Compliance
Beyond the sale agreement, several legal regimes shape how the handover works. Here are the big ones for UK small businesses.
TUPE (Employee Transfers)
For asset sales, the Transfer of Undertakings (Protection of Employment) Regulations 2006 (TUPE) usually apply. Employees assigned to the business transfer to the buyer on their existing terms and preserve continuity of service. You must inform (and in some cases consult) affected employees and provide specific information to the buyer ahead of transfer. Our guide on selling your business: employee rights covers what to expect and how to plan timelines.
Data Protection And Customer Lists
During diligence and at completion you’ll likely share personal data (employees, customers, suppliers). You must comply with UK GDPR and the Data Protection Act 2018. That means ensuring a lawful basis for sharing, minimising the data shared, using secure methods, and documenting roles with a Data Sharing Agreement. Update your Privacy Policy and internal records post-completion to reflect the change.
Customer And Supplier Contracts
In a share sale, contracts usually continue unchanged, but check for “change of control” clauses allowing termination or consent requirements. In an asset sale, you’ll need assignments or novations – and in some cases, customer re-onboarding. Build time for consents into your timeline.
Leases And Premises
Landlords often require financial information on the incoming tenant, rent deposits, and personal or parent guarantees in lease assignment cases. Factor these into your negotiations and cash flow. We’ve highlighted the steps and common conditions when assigning a lease.
Company Law And Filings
Under the Companies Act 2006, you’ll need proper board and shareholder approvals, stock transfer forms for share sales, and Companies House filings post-completion (e.g. updates to directors, PSCs and shareholders). Keep statutory registers accurate and up to date to avoid completion delays.
Tax And Deal Structure Considerations
Tax can materially alter your net proceeds and the overall attractiveness of a deal, so bring a tax adviser in early. Common UK issues include:
- Capital gains tax (CGT) – Sellers may benefit from Business Asset Disposal Relief (formerly Entrepreneurs’ Relief) on qualifying share disposals (subject to conditions), reducing CGT to 10% on the first £1m of qualifying gains.
- Stamp Duty – Share sales usually attract 0.5% Stamp Duty (rounded up to the nearest £5) on the consideration for shares. Buyers typically pay this, but it can be a negotiated point.
- VAT and TOGC – Asset sales may be treated as a Transfer of a Going Concern (TOGC) and outside the scope of VAT if conditions are met (e.g. the buyer is VAT registered and continues the same kind of business). This needs careful drafting in the Business Sale Agreement.
- SDLT – If property is included in an asset sale, Stamp Duty Land Tax may apply to the property transfer.
- Earn-outs and tax timing – If part of the price is contingent on future performance, clarify when tax is assessed and how you’ll evidence the earn-out metrics.
Because the right structure depends on your specific facts, tailored tax advice is a must. Align the commercial terms with tax planning from the outset – don’t bolt it on at the end.
Common Pitfalls To Avoid When You Sell A Limited Company
Here are frequent stumbling blocks that catch out sellers – and how to sidestep them.
- Unclear deal perimeter – In asset sales, be precise about what’s included or excluded. Inventory, WIP, debtors, refunds, deposits and prepayments need clear treatment.
- Gaps in IP ownership – If crucial brand assets or software live with founders or contractors, buyers will push price down or insist on holdbacks. Use an IP Assignment to bring everything under the company.
- Change-of-control surprises – A buried clause in a supplier or customer contract can trigger termination on a share sale. Audit key contracts early and plan consent strategies – or adjust price and risk allocation.
- Weak warranties and caps – Your liability should be time-limited and capped, with sensible thresholds and exclusions. Don’t accept open-ended indemnities without negotiation.
- Rushed disclosure – The disclosure letter protects you by qualifying warranties with specific known issues. Rushed disclosures create avoidable risk. Start compiling disclosures as soon as the first draft warranties are on the table.
- Underestimating TUPE – Information and consultation under TUPE has real timelines and penalties for non-compliance. Build this into your project plan and coordinate messaging to staff.
- Messy completion – Missing signatures, filings or consents can delay funds transfer. Use a robust Completion Checklist and a clear step plan so completion runs to time.
If this sounds like a lot to juggle, don’t worry – with the right advisers and a clear process, you can keep the transaction moving and avoid last-minute surprises.
Key Takeaways
- Decide early whether you’re pursuing a share sale or an asset sale – the choice affects risk, tax, timelines and the documents you’ll need.
- Get sale-ready: tidy accounts and contracts, fix IP ownership gaps, and put an NDA in place before sharing information.
- Expect diligence on finance, legal, people, IP and data; a seller-side pack or Legal Due Diligence Package helps you present the business cleanly.
- Use the right core agreement: a Share Sale Agreement for a company share sale or a Business Sale Agreement for an asset sale – and tailor warranties, caps and covenants to your deal.
- Plan consents and approvals: board/shareholder approvals (including any special resolutions), landlord and lender consents, and TUPE steps for employees.
- Stay compliant with UK GDPR and the Data Protection Act 2018 when sharing or transferring customer data, ideally under a Data Sharing Agreement.
- Don’t leave tax to the end: consider CGT, Stamp Duty on shares, VAT/TOGC and SDLT early so the structure and price mechanism support your tax position.
