Founder comparing Irish and UK company registration requirements

A UK private limited company is registered with Companies House, not the Irish CRO. It needs a suitable UK registered office, directors, shareholders, people with significant control, a business activity code and identity information under the current Companies House regime.

StartCompany.ie provides a contact-based UK company registration service for founders who want support preparing the filing. The UK tax, address and identity requirements should be confirmed before choosing a UK entity over an Irish company.

UK and Irish companies are separate choices

A UK company is not an Irish company with a UK trading name. It has Companies House filings, UK accounts and confirmation statements, and may have UK tax obligations. Trading in Ireland can create additional Irish registration and tax questions.

Base the choice on customers, management, staff, investment, banking and tax advice rather than the apparent speed of incorporation. A company can have obligations in both countries.

Information needed for Companies House

Prepare the proposed name, UK registered office, registered email, directors, shareholders, share structure, PSCs and SIC code. The company must use an appropriate address and make required information available on the register.

Companies House identity verification became a legal requirement and directors receive personal codes. Current official instructions should be followed because deadlines and filing journeys continue to develop.

  • Company name and UK registered office.
  • Director identity verification and personal codes.
  • Shareholders, shares and PSC details.
  • SIC code and lawful-purpose confirmation.
  • Post-formation tax, accounts and confirmation-statement plan.

Non-resident founder considerations

A non-UK founder may own and direct a UK company, but banking, tax residence, payroll, VAT and proof-of-address requirements are separate from Companies House incorporation. Formation does not provide immigration permission.

If management occurs from Ireland or another country, obtain cross-border tax advice. A UK registration does not ensure the company is taxed only in the UK.
