Ltd vs. LLP: UK Entity Structures for Acquisitions

When acquiring a business in the United Kingdom, the two most common legal structures you'll encounter are the Private Limited Company (Ltd) and the Limited Liability Partnership (LLP). According to Companies House data, there are over 5 million active Ltd companies and approximately 65,000 active LLPs registered in the UK. Understanding their differences is critical for structuring your acquisition, managing tax obligations, and planning for governance and exit.

The Ltd is the dominant structure for UK business acquisitions:

• Legal status: Separate legal entity with its own rights and obligations
• Liability: Shareholders' liability limited to their shareholding
• Minimum share capital: £1 (no practical minimum)
• Governance: At least one director. No minimum number of shareholders. Company secretary optional.
• Taxation: Corporation Tax on profits (currently 25% for profits over £250K; 19% small profits rate for profits under £50K; marginal relief between £50K-£250K)
• Share classes: Can create ordinary, preference, and other share classes with different rights
• Transfer: Share transfers are simple, no notarization required (unlike Germany)
• Stamp duty: 0.5% on share purchases above £1,000
• Companies House: Annual confirmation statement and accounts must be filed publicly

LLPs are used primarily for professional services firms:

• Legal status: Separate legal entity (unlike traditional partnerships)
• Liability: Members' liability limited to their capital contribution
• Minimum members: Two designated members required
• Taxation: Tax-transparent, profits are taxed at each member's individual income tax rate (up to 45% for additional rate taxpayers)
• National Insurance: Members treated as self-employed, Class 2 and Class 4 NIC applies
• Profit distribution: Flexible profit-sharing based on the LLP agreement
• No shares: Members hold membership interests, not shares, harder to create preference structures
• No stamp duty: On transfer of LLP interests (significant advantage for professional services acquisitions)

• Tax treatment: Ltd pays Corporation Tax (19-25%); LLP is transparent (members pay income tax up to 45%). For profitable businesses, Ltd is typically more tax-efficient.
• Investor compatibility: Ltd is strongly preferred. Investors can receive preferred shares, and governance is well-understood. LLP structures are less familiar to search fund investors.
• Debt financing: Banks strongly prefer lending to Ltd companies. LLPs can be harder to finance.
• Exit: Ltd shares are easily sold. LLP interests are harder to value and transfer.
• Professional firms: Many accounting, legal, and consulting firms are structured as LLPs. Acquiring one may require converting to Ltd or maintaining the LLP structure. The Law Society of England and Wales notes that most mid-sized law firm acquisitions involve either an LLP-to-Ltd conversion or a structured management buyout.

1. NewCo Ltd (SPV): Create a new limited company as the acquisition vehicle
2. Shareholder structure: Searcher and investors hold shares (ordinary + any preference shares) in NewCo, governed by a shareholder agreement
3. Bank financing: EFG-backed or commercial bank loans flow into NewCo
4. Share purchase: NewCo acquires 100% of the target Ltd shares
5. Group relief: Tax losses can be shared between NewCo and the subsidiary through group relief claims

• Business Asset Disposal Relief (BADR): 10% CGT rate on first £1M of qualifying gains (relevant for the seller, and for your eventual exit)
• EMI share options: Enterprise Management Incentive scheme allows tax-efficient equity for key employees post-acquisition. HMRC data shows that EMI is the most popular share option scheme for qualifying companies, with over 15,000 active schemes
• R&D tax credits: Enhanced deductions for qualifying R&D expenditure in the acquired business
• Annual Investment Allowance: 100% capital allowance on qualifying plant and machinery (up to £1M)
• Interest deductibility: Acquisition debt interest generally deductible (subject to corporate interest restriction rules at £2M de minimis)

• Ltd is the standard structure for UK acquisitions, preferred by investors, banks, and for governance flexibility
• LLP is common in professional services but less suitable for search fund structures due to investor and financing constraints
• UK share transfers are simple and inexpensive (0.5% stamp duty, no notarization), making exits straightforward
• Corporation Tax rates of 19-25% are competitive, with the small profits rate benefiting companies under £50K profit
• EMI share options provide a tax-efficient way to incentivize management post-acquisition

An Ltd is almost always the better choice. It is the standard structure for UK acquisitions, preferred by search fund investors (who can hold preference shares), banks (which strongly prefer lending to Ltd companies), and for governance flexibility. LLPs are common in professional services but create complications for search fund structures: no share classes, tax-transparency issues, and limited financing options.

Stamp duty on share purchases is 0.5% of the consideration, rounded up to the nearest £5, and applies to purchases above £1,000. This is significantly lower than in many European jurisdictions. LLP interest transfers, by contrast, attract no stamp duty at all, which is one of the few structural advantages of the LLP form in acquisition contexts.

There is no statutory conversion mechanism from LLP to Ltd in the UK. The typical approach is to incorporate a new Ltd company, transfer the LLP’s business, assets, and employees to the Ltd, and then wind down the LLP. This process requires careful planning around employment (TUPE regulations), lease assignments, contract novation, and tax implications. Budget 3-6 months and £10K-£30K in professional fees for a clean conversion.
