Companies House Change of Address

If you're looking to update your company’s registered office address, it's essential to notify Companies House. This can be done through an online submission or by sending the AD01 form via post. Affotax simplifies the process, ensuring that the change of address is handled smoothly and efficiently.


Step-by-Step Guide to Changing Your Company Address

  1. Notify Companies House: Once you decide to change your office address, the first and most crucial step is to inform Companies House. You can do this either online or by completing and mailing the AD01 form. Remember, the change will only be official once the new address has been registered by Companies House.
  2. Automatic HMRC Notification: After Companies House processes your company’s change of address, HMRC will automatically be informed. There is no need to notify them separately, which simplifies the process for you.
  3. Stay Within Your Region: When changing your company’s registered office, the new address must remain within the same part of the UK where your business was originally incorporated. For example, if your company was set up in England, the new registered office must also be in England. If you plan to move to another part of the UK, such as from England to Scotland, you may need to re-incorporate your company.

Completing the AD01 Form


To successfully complete and submit the AD01 form, you’ll need to provide the following information:

  • Company Number: This unique number, issued by Companies House, can be found on their website if you don't have it handy.
  • Company Name: Ensure the correct and full legal name of your company is provided. Any errors can cause delays in processing the change.
  • New Registered Office Address: Enter the new address in full, making sure it meets all legal requirements for a registered office.
  • Signature Authorisation: The AD01 form must be signed by a company director or another authorised person to confirm the change.

Reasons to Change Your Company’s Registered Office Address

Businesses might need to update their registered office address for several reasons, including:

  • Relocation: As companies grow, they may need to move to larger premises.
  • Virtual Offices: Some businesses opt for virtual offices for a more professional appearance while operating remotely.
  • Compliance: If the current address no longer functions effectively for communication, a change is necessary.

Common Pitfalls to Avoid

When updating your company’s address, be cautious of the following common errors:

  • Failure to notify Companies House: Simply relocating does not update your registered address. You must officially notify Companies House using the AD01 form.
  • Incomplete or inaccurate form submission: Ensure that all details on the form are filled out correctly to avoid rejection or delays.
