Companies House is the United Kingdom's registrar of companies and is an executive agency and trading fund of Her Majesty's Government, falling under the remit of the Department for Business, Energy and Industrial Strategy. All forms of companies (as permitted by the United Kingdom Companies Act) are incorporated and registered with Companies House and file specific details as required by legislation. All registered limited companies, including subsidiary, small and inactive companies, must file annual financial statements in addition to annual company returns, and all these are public records. Only some registered unlimited companies (meeting certain conditions) are exempt from this requirement.
