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.

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.

Frequently asked

Can a UK subsidiary be wholly owned by an overseas parent?

Yes. A UK private limited company can be 100% owned by a single overseas corporate shareholder. The overseas parent simply needs to be named as the registered shareholder and as the person with significant control (PSC) at Companies House.

How quickly can a UK subsidiary be incorporated?

Electronic incorporation at Companies House typically completes within 24 hours when the papers — director ID, registered office, Articles of Association and PSC details — are in order. Allow up to five UK business days end-to-end for ID verification and statutory housekeeping.

Does the subsidiary need to file UK accounts?

Yes. Every UK incorporated company files annual statutory accounts and a confirmation statement at Companies House, plus a corporation tax return with HMRC. Whether a UK audit is required depends on size thresholds — most early-stage subsidiaries are exempt.

Can the parent appoint its own directors to the UK subsidiary?

Yes. Directors of the UK subsidiary can be officers of the overseas parent. There is no UK residency requirement, but directors must complete UK identity verification and accept the legal duties of a UK company director.
