Documents for Companies House

Generally, your company and limited liability partnership must submit the following documents to the Registrar of Companies. This includes dormant companies and non-trading companies. Additionally, all documents must comply with the Companies Act 2006.

Usually, Companies House would send reminders to your registered office address when your filings become due. For this reason, it is important you update your registered office with Companies House if your existing registered office address no longer valid. For example, you recently moved to a new office. You are required by law to notify Companies House of this event by law. For this purpose, use the form AD01 to update your registered office address.

Normally, you can either file this form online using the web filing service or by post. For online filing, you would require your company’s authentication code. You must keep this code safe and do not disclose to anyone.

If you have lost your authentication code, you may request the code again from Companies House.

On the other hand, if you would like to send your company accounts by post, send it to one of the companies house office listed above. For example, if your company’s registered office is in England, then send your Signed company accounts to either Companies House in Cardiff or London office.
