How to Set Up a UK Subsidiary: A Practical Guide for Overseas Companies
Setting up a UK subsidiary is straightforward at the registration stage. The more important work is deciding how the UK company will actually operate: who owns it, who directs it, where decisions are made, how it contracts, banks, accounts for tax and remains properly governed after incorporation.
Updated 30 October 2026
What is a UK subsidiary?
A UK subsidiary is a separate UK legal entity owned by another company, often an overseas parent. In the usual structure, the parent owns all or a majority of the shares in a UK private company limited by shares.
The subsidiary can contract with customers and suppliers, employ staff, hold a UK bank account and carry on its own business. Because it is legally distinct from the overseas parent, it is different from a UK branch or UK establishment, which remains part of the foreign company itself.
How to set up a UK subsidiary
The incorporation itself is only one step. A robust market-entry process normally covers the following areas.
| Area | Practical question |
|---|---|
| Ownership | Will the overseas parent own 100% of the shares, or will other investors participate? |
| Directors | Who will exercise real board responsibility and make decisions for the UK company? |
| Registered office | What compliant UK registered office and corporate records arrangements will be used? |
| Banking | What evidence of ownership, management, activity and source of funds will the bank require? |
| Tax & accounting | How will Corporation Tax, VAT, payroll, accounts and intercompany transactions be managed? |
| Operations | Who will contract, invoice, hire, approve expenditure and manage the UK business? |
| Governance | How will board decisions, parent-company instructions and UK director duties be documented? |
1. Decide the ownership structure
An overseas corporate shareholder can own a UK limited company. For many international groups the cleanest starting point is a wholly owned subsidiary, but the share structure should still reflect the commercial plan, future investment and any expected joint-venture or management participation.
The people who ultimately own or control the company may also fall within the UK people-with-significant-control regime, so the ownership chain should be understood before incorporation rather than reconstructed afterwards.
2. Appoint the directors
A UK private limited company must have at least one director. Under current Companies House rules, a director must be at least 16 and does not have to live in the UK. The company itself must, however, maintain an appropriate UK registered office.
For a foreign parent, the legal minimum is not necessarily the best operating model. The board should reflect how the UK business will actually be managed and who will take responsibility for local decisions.
Do you need a UK-resident director?
Not generally as a Companies House incorporation requirement. A UK company can have directors who live overseas. But some international businesses choose to appoint an experienced UK-based director because they want genuine local governance, practical oversight and a consistent point of coordination in the UK.
This can be particularly relevant where the parent company wants the UK subsidiary to develop its own operational presence, board process and relationships with UK accountants, lawyers, banks, employees and commercial counterparties.
UK independent director and governance support
For businesses considering an ongoing appointment, see UK Resident Director & Governance Services for Overseas Companies.
A properly structured independent director service is not simply the provision of a name for Companies House. A UK director assumes real legal responsibilities to the company.
Under the Companies Act framework, directors must act within their powers, promote the success of the company, exercise independent judgement, use reasonable care, skill and diligence, manage conflicts and comply with their other statutory obligations. Those responsibilities continue even where the shareholder or overseas parent gives instructions.
For suitable overseas groups, the governance model can include UK board participation, corporate oversight, coordination of Companies House obligations, liaison with accountants and legal advisers, review of material decisions and an organised reporting line back to the overseas shareholder.
3. Complete Companies House incorporation and identity verification
Companies House identity verification is now part of the UK corporate compliance framework. New directors need to satisfy the applicable identity-verification requirements and use their Companies House personal code for relevant appointments and filings. People with significant control are also within the verification regime.
This makes it increasingly important to design the ownership and management structure correctly at the outset and to keep corporate records aligned with the people actually directing and controlling the company.
4. Build the banking and operating model
Incorporation does not guarantee a bank account. Banks and payment institutions conduct their own onboarding and will normally want to understand the group, beneficial ownership, directors, expected activity, countries involved, source of funds and commercial rationale for the UK company.
The strongest approach is to prepare the company and its evidence around a genuine business model rather than treating banking as an administrative step after formation.
5. Put accounting, tax and reporting in place
A UK subsidiary has its own accounting and corporate obligations. Depending on its activity, this can involve annual accounts, Corporation Tax, VAT, PAYE/payroll and other filings. Intercompany charges, financing and transactions with the overseas parent should also be documented and reviewed appropriately.
Professional advisers can perform much of the day-to-day work, but directors remain legally responsible for ensuring the company is properly run and its required information is filed.
6. Define how the parent and UK subsidiary will work together
This is frequently overlooked. The parent owns the subsidiary, but ownership does not eliminate the subsidiary’s separate legal identity or the duties of its directors.
Before trading begins, it is useful to define authority levels, board approvals, banking mandates, intercompany agreements, reporting, major expenditure, contracting authority and which decisions remain reserved for the shareholder. Good governance allows the parent to maintain strategic control without confusing shareholder rights with the director’s legal responsibilities.
UK subsidiary with ongoing governance support
For overseas businesses, I prefer to treat UK market entry as an ongoing operating relationship rather than a one-off company formation. Depending on the client and the activities involved, support can bring together company formation, registered-office and corporate administration, independent UK director/governance support, banking coordination, accounting and tax coordination and liaison with specialist legal or regulated professionals.
The objective is a UK company that works commercially after incorporation — not simply a certificate of incorporation.
UK subsidiary or UK branch?
A subsidiary is not always the correct structure. Some overseas companies are better served by operating through a UK establishment of the parent. The choice affects liability, corporate identity, filings, contracts and the way the UK operation relates to the overseas business.

Frequently asked questions
Can a foreign company own 100% of a UK limited company?
Yes. An overseas company can be the shareholder of a UK private limited company, including as its sole shareholder.
Does a UK company need a UK-resident director?
Not generally. Companies House states that directors do not have to live in the UK. A UK-based independent director may nevertheless be useful where the business requires genuine local governance and oversight.
What does a UK independent director do?
The precise mandate depends on the company, but the role can include board participation, governance, review of material decisions, corporate oversight and coordination with professional advisers. The director must exercise independent judgement and comply with UK directors’ duties.
Can a UK director simply act on the instructions of the overseas shareholder?
No. Shareholders can exercise their rights as owners, but a director has duties to the company and must exercise independent judgement. A professional director appointment therefore needs a genuine governance framework rather than a passive nominee arrangement.
Do directors now need Companies House identity verification?
Yes. Identity verification is now a legal requirement within the Companies House regime, with personal codes used for relevant director appointments and company filings.
Is setting up the company enough to enter the UK market?
No. Incorporation is only the legal starting point. Banking, contracts, tax, accounting, governance, people and the relationship with the overseas parent all need to work together.
Establishing a UK subsidiary?
I work with overseas companies on UK market entry, subsidiary structuring and ongoing governance, coordinating the appropriate accounting, tax, legal and corporate specialists where required. For suitable businesses, this can include independent UK director and governance support as part of a wider UK operating model.
