The AD01 form is used to tell Companies House about changes to a limited company‘s registered address. The change can also be reported online.

Updating your registered address with Companies House

By law, every limited company must have a registered office address, which should be recorded and kept up-to-date with Companies House. The registered office address is used for formal communications, but it doesn’t have to be the place where business actually takes place.

Can I use any address as my registered office address?

When you provide a registered office address for a limited company, it must be a real address, complete with postcode. Unfortunately this means that you’re not allowed to use a PO Box address, and Companies House won’t accept it. If you’re one of a number of businesses who have an accountant acting as their company secretary, then you can list your registered office as your accountant’s address.

Companies House will use the registered office address to send important communications, so it’s essential that you have access to this address to pick up any paperwork without risk of it becoming overdue. You’re also required to make sure that the registered address is used on any company documents that you use, such as letters.

The company registers, showing shareholders and directors, is usually kept at the registered office address, too (though you can notify Companies House if they’re stored in a different place). If the address changes, then you’ll need to let Companies House know that the records have moved to a new location, as well as letting them know the new registered office details.
