UK Private Unlimited Company (ULC)
A Private Unlimited Company (ULC) is registered at Companies House but is NOT required to file its annual accounts publicly — making it the preferred structure for businesses that value privacy and confidentiality of financial information.
Financial Privacy
Under s.448 Companies Act 2006, a standalone ULC is generally exempt from filing annual accounts at Companies House — keeping financials private from competitors, clients, and the public. The primary structural advantage of the ULC.
Capital Flexibility
A ULC can issue and redeem shares freely without the restriction on capital distributions that applies to limited companies under the Companies Act 2006 — ideal for complex group restructuring and inter-company capital flows.
100% Foreign Ownership
No UK partner, local sponsor, or director residency requirement. Members can be foreign individuals or overseas corporate entities. Liability risk is managed by using corporate entities (e.g. Ltd companies) as members rather than individuals.

Key facts for a Private Unlimited Company registered at Companies House
Who is this for?
A Private Unlimited Company (ULC) is incorporated under the Companies Act 2006 at Companies House — but unlike a limited company, its members bear unlimited personal liability for the company’s debts. This is offset by the primary benefit: standalone ULCs are generally exempt from filing annual accounts publicly (s.448 CA 2006), maintaining financial confidentiality. It is used strategically by multinational holding structures, where corporate entities act as members to manage liability risk.
Ideal Use Cases:
- Multinational Group Holding Companies & Intermediate Subsidiaries
- Private Equity & Family Office Holding Structures
- Intra-Group Finance & Treasury Companies
- Joint Ventures where financial privacy is commercially sensitive
- Asset-Holding Vehicles for IP, Property, or Investments
Use a Ltd Company Instead If:
- Financial privacy is not a priority → Ltd is simpler and offers full liability protection
- Members are individuals (not corporates) → unlimited liability is a personal risk
- You need external investors or bank financing → Ltd or PLC is preferred
- The ULC is a subsidiary of a limited company → the accounts exemption may not apply
Formation Requirements
- Minimum 1 Member (Shareholder): At least one member — an individual or corporate entity of any nationality. No UK residency requirement. For liability risk management, corporate entities (e.g., Ltd companies) are used as members rather than individuals.
- Minimum 1 Director: At least one director who is a natural person. No UK nationality or residency required. Directors can be located anywhere in the world.
- UK Registered Office: A physical address in England & Wales, Scotland, or Northern Ireland. Virtual or serviced office addresses are accepted.
- Memorandum & Articles of Association: Standard or bespoke Articles must be drafted and filed with Form IN01. Select “unlimited” company type during Companies House registration.
- No Minimum Share Capital: There is no minimum paid-up share capital requirement. Shares can be structured and issued flexibly to suit the group structure.
The Roadmap to Launch
Typical timeline: Same day – 2 working days (online registration via Companies House WebFiling)
Structure & Member Plan
Decide the member structure. For liability risk management, use corporate entities (e.g., UK Ltd or overseas companies) as members rather than individuals. Confirm director appointments and registered office address.
Draft Articles of Association
Prepare bespoke Articles of Association (or adopt the Model Articles for unlimited companies). The Articles govern share structure, member rights, director authority, and profit distribution rules.
File Form IN01
Submit Form IN01 to Companies House via WebFiling (£50 online / £71 paper). Select “Unlimited” as the company type. Include all member and director details, the registered office address, and the Articles. Approved same day or next working day.
Certificate of Incorporation
Receive your official Certificate of Incorporation with a unique Companies House Registration Number. Confirm the accounts exemption position: standalone ULCs generally need not file accounts publicly. Check if subsidiary rules (s.448 CA 2006) apply to your structure.
HMRC Corporation Tax
Register for Corporation Tax with HMRC within 3 months of beginning to trade. A ULC pays the same Corporation Tax rates as a Ltd company (19% for profits up to £50,000; 25% for profits above £250,000; marginal relief in between). File annual CT600 with HMRC.
VAT Registration
Register for VAT with HMRC if taxable turnover exceeds £90,000/year (2024/25 threshold). Voluntary registration available below the threshold. All VAT returns filed via HMRC’s Making Tax Digital (MTD) platform.
Open Business Bank Account
Open a UK corporate bank account in the ULC’s name. Provide the Certificate of Incorporation, Articles of Association, and director/member ID. Challenger banks (Starling Business, Tide, Monzo Business) typically onboard more quickly than traditional high-street banks.
Ongoing Annual Compliance
File annual Confirmation Statement (£34 online) with Companies House. Prepare annual accounts (not required to be filed publicly for standalone ULCs). File Corporation Tax Return (CT600) with HMRC annually. If employing staff, register as an employer with HMRC for PAYE and NIC.

Frequently Asked Questions
Does a UK ULC have to file accounts at Companies House?
Generally no. Under s.448 of the Companies Act 2006, a standalone private unlimited company is exempt from filing its annual accounts at Companies House — keeping financials private. However, this exemption does not apply if the ULC is a subsidiary of a limited company (Ltd or PLC), or is itself a parent of a limited company. Always take legal advice to confirm the exemption applies to your specific structure.
What is the liability risk and how is it managed?
Members of a ULC bear unlimited personal liability for the company’s debts — there is no liability cap. To manage this, members are typically corporate entities (Ltd companies) rather than individuals. A Ltd company member has its own limited liability, effectively creating a “double layer” of liability protection for the underlying human owners. This is the standard structure used by multinational holding groups.
Does a ULC pay Corporation Tax?
Yes. A UK Private Unlimited Company pays Corporation Tax on its profits at exactly the same rates as a Private Limited Company: 19% for profits up to £50,000; 25% for profits above £250,000; and marginal relief applies between £50,000 and £250,000. A CT600 Corporation Tax Return must be filed with HMRC each year.
What are the annual compliance obligations?
A ULC must: (1) file an annual Confirmation Statement (£34 online) with Companies House; (2) prepare annual accounts (but typically not file them publicly for standalone ULCs); (3) file a Corporation Tax Return (CT600) with HMRC; (4) register and file for VAT if turnover exceeds £90,000/year; (5) operate PAYE if employing staff.
Can a ULC pay dividends and repatriate profits?
Yes. A ULC can distribute profits to members as dividends in the same way as a Ltd company, provided the company remains solvent. There are no restrictions on repatriating profits overseas. Dividend payments to non-UK resident shareholders may be subject to UK withholding tax depending on any applicable Double Tax Treaty between the UK and the member’s country of residence.
Can a foreign national or overseas company be a member of a ULC?
Yes. There are no nationality or residency restrictions. Foreign individuals and overseas corporate entities can be members and directors of a UK Private Unlimited Company. Companies House requires that at least one director is a natural person; there is no requirement for UK residency.
