Companies House is the home of the Registrar of Companies with responsibility for maintaining the register of all companies registered in the UK. All GB companies, irrespective of their size or complexity, have a responsibility by law to register their basic details with Companies House, keep them informed of any subsequent changes, and file regular reports such as an annual return, annual accounts and other key documents. This guide covers all statutory filing requirements, noting the necessary filing periods and any penalties for non-compliance. It also gives advice on the range of information available from Companies House, whether in person, via the telephone or their website or through the Companies House Direct service.
