The United Kingdom (U.K.) offers access to top talent, but figuring out how to set up a subsidiary in the U.K. can take months and delay your plans. Plus, ongoing compliance requirements slow hiring timelines, making it harder to secure candidates when you need them. However, G-P offers an alternative. Instead of taking the conventional subsidiary route in the U.K., we can expedite your entry — no new entities required — so you can start hiring in minutes, not months.

How to set up a subsidiary in the U.K.

A subsidiary is legally separate from its owners, shareholders, and directors. The most common type in the U.K. is a private company limited by shares (Ltd), as it offers flexibility, separate legal personality, and shareholder liability protection. 

Steps to incorporate a subsidiary in the U.K.

1. Choose a company name: It needs to comply with U.K. regulations and it can’t be a name that’s already registered with Companies House, the U.K.’s registrar of companies. 2. Secure an address: Choose a registered office address where official correspondence can be sent and acknowledged. It must be a physical address in the same UK country where the company is registered, and cannot be a Royal Mail PO Box. 3. Appoint stakeholders: Appoint at least one director, who must be a natural person, and at least one shareholder. The same person may be both the sole director and sole shareholder. Their details must be submitted during registration. 4. Identify persons with significant control (PSC): Identify any people or entities that own or control your company. You must identify your PSCs and keep their information accurate and up to date with Companies House. Most company directors and PSCs must also verify their identities with Companies House, with timing depending on whether they are new or existing appointees. 5. Create a memorandum and articles of association: These documents outline your company’s rules and what it does. 6. Register with Companies House: Apply to incorporate your company with Companies House. This is usually done online.

After company registration in the U.K., you also need to:

  • Open a corporate bank account: This can be a lengthy process, but it’s essential for managing finances, payroll, and taxes.
  • Register with His Majesty's Revenue and Customs (HMRC): Register with HMRC for Corporation Tax within three months of starting to do business.
  • Register for pay as you earn (PAYE): Before hiring your first employee, you must register with the PAYE system for income tax and National Insurance contributions.
  • Register for value-added tax (VAT): Registration for VAT is mandatory if your VAT-taxable turnover exceeds GBP 90,000 in a rolling 12-month period. You must also register if you expect it to exceed this threshold in the next 30 days.
  • Get liability insurance: You need at least GBP 5 million in employer’s liability coverage from an authorized insurer as soon as you employ staff in Great Britain, unless an exemption applies.

U.K. subsidiary laws and requirements

You have to meet several legal requirements to set up a subsidiary company in the U.K.:

  • Management: Directors must comply with duties set out in the Companies Act 2006, including promoting the company’s success, avoiding conflicts, and exercising reasonable care, skill, and diligence.
  • Taxation: Companies generally pay the 25% main rate of Corporation Tax on profits over GBP 250,000. Lower profits may qualify for the small profits rate or marginal relief.
  • Share capital: At least one share must be issued when the company is formed. There is no statutory minimum share capital for an Ltd company, but GBP 1 is common. 
  • Accounting and reporting: Annual accounts are filed with Companies House each financial year. A separate confirmation statement must also be filed at least once every 12 months.

Advantages of U.K. subsidiaries

  • Market access: Establishing a subsidiary in the U.K. gives you direct access to the local market, boosting business and customer growth.
  • Limited liability: The parent company’s liability is generally limited to its investment in the subsidiary, reducing your financial risk. This protection is not absolute where the parent gives guarantees, assumes responsibility, or is directly involved in wrongdoing.
  • Legal entity status: A subsidiary is a separate legal entity that can enter into contracts, own assets, and hire employees independently.
  • Established presence: Having a registered U.K. entity signals a strong, long-term commitment to the market. This builds credibility with local customers, partners, and talent.
  • Tax benefits: Setting up a subsidiary in the U.K. can offer tax advantages, but these depend on your business activities, structure, and long-term goals.

Disadvantages of U.K. subsidiaries

Managing a U.K. subsidiary comes with heavy administrative burdens and financial liabilities. While direct entity ownership offers control, the path to market capture is often slow and resource-intensive compared to using G-P’s Global Employment Platform.

High costs and resource demands

Setting up a subsidiary is a major capital investment including:

  • Legal fees: High upfront costs for registration and professional counsel.
  • Physical infrastructure: Maintaining a registered office and local bank accounts.
  • Capital: Significant day zero investment to cover incorporation and licensing.

Administrative complexity

A U.K. subsidiary is a separate legal entity. Your organization must manage all local operations independently.

  • Reporting: You must meet full U.K. statutory filing obligations, including annual accounts and tax returns.
  • Governance: You must appoint directors who bear personal liability for company compliance.
  • Setup times: Building a functional subsidiary can take months — often causing you to miss critical market opportunities.

Compliance and legal risks

Operating an entity in the U.K. shifts all legal risk to your organization.

  • Taxation: You must navigate complex corporation tax laws and HMRC transfer pricing rules.
  • Employment liability: As the legal employer, your organization is responsible for HR compliance and adhering to U.K. labor laws.
  • Regulatory shifts: You must adapt to changing frameworks, which increases the risk of costly errors without in-country experts.

Alternative to setting up a U.K. subsidiary

G-P lets you hire talent in minutes without the hassle of entity setup.

The benefits of using an employer of record (EOR) in the U.K. include:

  • Faster market entry: An EOR lets you enter the U.K. market and begin hiring in a fraction of the time it would take to set up an Ltd company. Setting up a subsidiary can take months due to regulatory, banking, and admin requirements.
  • Compliance assurance: The EOR acts as the legal employer for your U.K.-based team, taking on all statutory obligations. This includes registering with HMRC for PAYE, handling payroll, deducting and remitting income tax and National Insurance, and ensuring compliance with labor laws like the Employment Rights Act 1996, Working Time Regulations 1998, and Equality Act 2010. 
  • Administrative simplicity: The EOR manages all HR and payroll administration, as well as employer and employee tax filing. You don’t need to draft compliant employment contracts or manage statutory benefits like annual leave and pensions — the EOR does it for you.
  • Cost efficiency: Setting up and maintaining a subsidiary, like an Ltd company, has major upfront and ongoing costs, including legal fees, accounting, local management, and administrative overhead. An EOR is more cost-effective, especially if you’re hiring a small team or testing the U.K. market.
  • Flexibility: An EOR arrangement is easier to scale up or down compared to winding down a subsidiary.
  • Risk mitigation: An EOR manages the legal risks associated with employment, such as worker classification, giving you an added layer of protection.

FAQs

Can a parent company outside the UK own 100% of a UK private limited company?

Yes. A foreign corporate shareholder, including a parent company outside the UK, can own 100% of a UK private limited company limited by shares. The UK subsidiary remains a separate company registered at Companies House. The system records shareholder details separately from People with Significant Control (PSC) information and identity checks.

What is Companies House identity verification and what are personal codes?

Companies House identity verification confirms the identity of directors and PSCs. The phased regime mandates this process legally. Individuals can verify directly or through an Authorised Corporate Service Provider (ACSP). They then use their reusable 11-character personal code for relevant director and PSC filings.

What PSC information do companies need when the shareholder is a US company?

Shareholder details stay separate from PSC disclosure. For a US parent shareholder, the UK incorporation record must capture its legal name, principal office, legal form, governing law, registration number, and held shares. For PSC purposes, the UK company must look through a non-UK parent to identify registrable ultimate individual PSCs, unless an exception applies.

What intercompany agreements should a US parent and UK subsidiary have?

Intercompany agreements must document actual group dealings and align with invoices, accounting entries, tax filings, and daily operations. A US parent and UK subsidiary may need service agreements, IP licenses, intercompany loan terms, secondment agreements, data-processing terms, and supply arrangements. Arm’s-length transfer pricing analysis supports these contracts for compliance purposes.

Do directors of a UK subsidiary need to live in the UK?

Directors of a UK subsidiary do not need to live in the UK. A UK private limited company must have at least one eligible natural-person director aged 16 or over who is not disqualified. The company must also maintain a compliant UK registered office for official notices.

What UK tax registrations does a company need after incorporation?

Online incorporation sets up the company for Corporation Tax, unless the business is dormant. After HMRC issues the Unique Taxpayer Reference (UTR), add Corporation Tax to the business tax account to manage filings. Register for PAYE before the first payday if paying supported professionals or directors. Register for VAT when taxable turnover demands it, and evaluate EORI, CIS, or sector-specific registrations.

What information do you need to incorporate a UK company online?

To incorporate online, prepare the proposed company name, UK jurisdiction, registered office, registered email, and SIC code. Provide director details, Companies House personal codes, shareholder details, share structure, PSC details, articles of association, and the memorandum. The filer must confirm lawful purpose, director eligibility, identity-verification status, and Companies House compliance before submitting.

What is the difference between a UK subsidiary and a UK branch?

A UK subsidiary is an independent UK legal entity, usually a private limited company. It can enter contracts, hire talent, hold assets, and limit shareholder liability. A UK branch is an extension of the parent company, leaving the parent directly liable for branch obligations, debts, and compliance exposure.

What UK registered office address does a UK subsidiary need?

Every UK subsidiary must maintain a registered physical address in its incorporation jurisdiction: England and Wales, Scotland, or Northern Ireland. The address must accept official documents, remain visible to the public, and avoid standalone PO Boxes. Service provider addresses work if they meet compliance standards.

What are the Companies House setup details to incorporate a UK Ltd?

To incorporate a UK private limited company, Companies House needs an available company name, at least one shareholder, and at least one eligible director aged 16+. The application must include an appropriate UK registered office address, a registered email address, share capital details, PSC information, identity verification codes, a memorandum, articles, a SIC code, and compliance statements.
