How can I informally wind-up my company? 

A director can apply to the Registrar of Companies to have a private limited company ‘struck off’. The director must serve notice on all the company’s shareholders, any directors who have not signed the application form, creditors, employees and managers or trustees of any company pension fund. This enables them to object. The relevant legislation is section 652A of the Companies Act 1985. For further information, see the Companies House leaflet GBW2 ‘Striking-off, Dissolution and Restoration’, which is available free of charge. The quickest way to obtain a copy is through their website:

www.companies-house.gov.uk  or by telephoning: 0870 3333636.

Alternatively, you may find that if the Registrar of Companies believes that a company may be dormant, he may strike the company off.
