UK Establishment Registration for an Overseas Company

An overseas business entering the UK does not always need a new British subsidiary. Where the foreign company itself will open a place of business or habitually conduct business from a UK location, registering a UK establishment can preserve the existing legal entity while creating the Companies House presence required for the British operation.

That can be commercially efficient, particularly where contracts, licences or group policy favour operating through the overseas parent. It also means the parent itself remains the legal entity behind the UK establishment, so liability, accounts, disclosure and tax consequences should be compared carefully with a separate UK Ltd before the route is chosen.

A UK establishment is not a separate subsidiary

GOV.UK requires an overseas company to register if it sets up a place of business in the UK or usually carries on business from somewhere in the UK. The registration records the overseas company and its UK establishment rather than incorporating a new British legal person.

This distinction matters to contracts and liability. Customers dealing with the establishment are ultimately dealing with the overseas company, which may be exactly what the group wants — or a reason to prefer a ring-fenced UK subsidiary.

Registration has a one-month deadline

Form OS IN01 must be filed within one month of opening for business. The application requires information and supporting documents relating to the overseas company and the UK establishment, and the current Companies House registration fee is £124.

All directors of the overseas company are now within the Companies House identity-verification framework. Current OS IN01 guidance requires the relevant personal codes and confirmation that directors have verified their identity.

The ongoing filing burden follows the overseas company

Registered overseas companies have continuing Companies House filing and disclosure obligations, including requirements relating to accounts and changes in company particulars. Current guidance also includes the OS VS01 director identity-verification confirmation regime.

UK Corporation Tax, VAT, payroll and sector obligations are separate questions. An overseas company without a UK base may not need Companies House registration but can still have UK tax obligations, illustrating why corporate registration and tax presence should not be confused.

How Coutts Consultants approaches a UK establishment

We first compare branch-style establishment with a UK subsidiary, considering liability, contracts, governance, accounts and tax. Where the establishment route fits, we coordinate the overseas corporate documents, director verification, OS IN01 and Companies House process.

We then identify Corporation Tax, VAT, PAYE, accounting, licensing and banking requirements for the UK activity. The objective is to use the overseas company directly because it makes commercial sense, not merely to avoid incorporating a subsidiary.
