When registering a limited company with Companies House, you must choose to register it in one of four domiciles: England and Wales, Wales, Scotland or Northern Ireland. You must also provide a physical address, situated within the domicile in which your private company is registered, as a registered office address. Companies House verifies all registered office addresses through the Post Office, so you must ensure that the Post Office recognises your chosen registered office address.
The registered office address serves as the official address of your company and it is essential as any document delivered to this address is considered by law to have been delivered directly to your company. Therefore, your registered office address is the address that Companies House, HM Revenue and Customs, other government departments and the courts of law will use to send important correspondence to your company. Companies House will also publish the details of your registered office address in its public records.
