Setting Up a UK Subsidiary

A practical walkthrough of incorporating a wholly-owned UK subsidiary — directors, registered office, Articles of Association, statutory filings and tax.

Setting Up a UK Subsidiary — Setupinuk guide hero image

The UK remains one of the most accessible jurisdictions in the world for international companies to establish a controlled, separately-incorporated presence. A UK subsidiary is a company incorporated under UK law whose shares are held — wholly or in part — by an overseas parent. Once registered, it operates as its own legal person.

What is a subsidiary, and what is a parent?

A parent company is the existing overseas business that holds a controlling shareholding in the UK entity. The UK subsidiary is a separate legal entity, governed by UK law, with its own directors, accounts and tax registrations. Strategic direction may sit with the parent, but day-to-day legal responsibility sits with the subsidiary.

Why companies choose a subsidiary

  • Limited liability — the parent and its shareholders are not normally liable for the subsidiary's debts.
  • Credibility with UK banks, landlords, suppliers and enterprise customers that prefer to contract with a UK entity.
  • Flexibility to issue shares, run UK payroll, sponsor visas and (eventually) list on a UK exchange.
  • A clean container for the UK market that does not contaminate the parent's brand, reporting or customer base.

Disadvantages to weigh

A subsidiary brings UK statutory accounts, corporation tax filings, a possible statutory audit, and ongoing governance load. For very early-stage market tests, a branch (or simply trading from overseas) may be lighter — see our Branch vs Subsidiary guide.

How a UK subsidiary is incorporated

The default vehicle is a Private Limited Company ("Ltd"). Incorporation is filed at Companies House and is typically completed within hours when papers are in order.

What Companies House needs

  • At least one named director (a natural person), with a service and residential address.
  • A UK registered office address (a virtual address is acceptable).
  • At least one shareholder — for a wholly-owned subsidiary, this is the overseas parent.
  • Memorandum and Articles of Association (Model Articles are often adopted).
  • Details of persons with significant control (PSCs).

After incorporation

  • Register for UK corporation tax with HMRC (automatic, but confirm the UTR).
  • Register for PAYE if you will employ anyone in the UK.
  • Register for VAT if taxable turnover exceeds the £90,000 threshold (or voluntarily, earlier).
  • Open a UK business bank account — digital banks (Wise, Revolut Business) typically take a week; traditional banks 3–6 months.
  • File a Confirmation Statement and statutory accounts annually.
