Form AD01 is a new form used by UK business owners who want to change their registered office information. It was first introduced on October 1, 2009.

Any change in the UK company registered office made after September 2009 must be submitted on form AD01.


This form is required to notify Companies House of any changes to a company's registered office address. The form has been updated in line with new regulations under the Economic Crime and Corporate Transparency Act as of March 2024, but it remains a critical document for any company wishing to change its registered office address.

Historical Context of the AD01 Form

The AD01 form was introduced on October 1, 2009, under the Companies Act 2006. It replaced the form 287, which previously served the same purpose.

This guide provides a step-by-step walkthrough of how to fill out the AD01 form correctly, helping you avoid any potential errors or delays.


Understanding the AD01 Form

The AD01 form is used by UK companies to notify Companies House of a change in their registered office address. The registered office is the official address of a company where all statutory documents and communications from Companies House and HM Revenue and Customs (HMRC) are sent. It must be a physical address in the UK and cannot be a PO Box, except in cases where a full address and post code are provided.

This form was introduced as part of the Companies Act 2006 and replaced the older Form 287. It is crucial for ensuring that your company’s public record is up to date, and failing to submit it within the required timeframe can result in penalties.


Step 1: Accessing the AD01 Form

You can obtain the AD01 form directly from the Companies House website or use a company formation agent that provides this service. The form is available in a PDF format, which you can fill out electronically or print and complete manually.

Alternatively, you can submit the form online through the Companies House WebFiling service, which is a quicker and more convenient option. However, for companies in liquidation or under certain specific circumstances, you may need to submit the paper form.


Step 2: Company Information

The first section of the AD01 form requires basic information about your company. Here’s what you need to fill out:


  • Company Number: This is the unique number assigned to your company when it was incorporated. You can find it on the certificate of incorporation or through Companies House’s online search service.

  • Full Company Name: Enter the full registered name of your company, exactly as it appears on the Companies House register. Any discrepancy in spelling or punctuation can cause delays.


Ensure that this information matches what is currently on file with Companies House to avoid any processing issues.


Step 3: New Registered Office Address

The next section is where you provide the details of your new registered office address. This must be a full postal address within the UK:


  • Building Name/Number and Street: Enter the street address where your company will be officially located.

  • Town/City: Include the town or city name as part of the address.

  • County: This is optional, but if relevant, include the county.

  • Postcode: The postcode is a crucial part of the address. Ensure it is accurate, as it is used to identify the location.


Remember, the address you enter here will be publicly accessible via Companies House records, so it should be a location where you can reliably receive official correspondence.


Step 4: Signature and Date

The AD01 form must be signed by an authorized person. This could be a company director, secretary, or any other officer of the company who is authorized to make such changes:


  • Signature: The form must be signed by an individual who is listed as an officer of the company.

  • Date: You must date the form on the day it is signed. This date is essential because you are legally required to notify Companies House within 14 days of the change.


If you are submitting the form electronically through WebFiling, a physical signature is not required. Instead, you will use your company’s authentication code.


Step 5: Submission

Once you’ve completed the form, it’s time to submit it to Companies House. There are two main methods of submission:


  • Online Submission: If you choose to submit the AD01 form online, log in to the Companies House WebFiling service using your company’s authentication code. The online form is straightforward and guides you through each section. Upon successful submission, the change is usually processed within 24 hours.

  • Postal Submission: If you are submitting the form by post, ensure that it is sent to the appropriate Companies House address based on your company’s jurisdiction (England and Wales, Scotland, or Northern Ireland). Postal submissions take longer to process, typically several days to a week.


Step 6: Confirmation and Record Keeping

After submitting the form, Companies House will process the change and update the public register. You should receive a confirmation from Companies House, which serves as proof that the change has been made.


It’s important to keep a copy of the completed AD01 form and the confirmation from Companies House in your company’s records. This documentation can be crucial if there are any future disputes or queries regarding the registered office address.


Common Mistakes to Avoid

  • Incorrect Address: Double-check the address details before submission. An incorrect address can lead to lost correspondence and may cause issues with compliance.

  • Late Submission: Ensure that the form is submitted within 14 days of the address change. Late submissions can result in penalties and complications with Companies House.

  • Missing Signatures: Make sure the form is signed by an authorized person. An unsigned form will be rejected, leading to delays.

  • Use of PO Box: Avoid using a PO Box as the registered office address unless it includes a full street address and postcode.


What Happens After Submission?

Once Companies House updates your registered office address, the change will be reflected in the public records. This information is available to anyone who searches for your company’s details, so it’s important that the address is correct and that you are prepared to receive official documents there.

Additionally, HMRC will be notified of the change, ensuring that all tax correspondence is sent to the correct address.


Filling out and submitting the AD01 form is a straightforward process, but it must be done correctly to ensure compliance with UK company law. By following this step-by-step guide, you can efficiently update your company’s registered office address and avoid any potential issues with Companies House. Whether you choose to file the form online or by post, ensuring accuracy at every step is key to a smooth and hassle-free experience.


By following these steps, you can ensure that your AD01 form is filled out correctly and efficiently, helping your business maintain compliance with Companies House requirements. Remember, the registered office address is a critical piece of information for your company, and keeping it updated is key to smooth business operations.



How to Submit an AD01 Form?

It is important that a business owner provide all the information requested by Companies House on their AD01 form. The information requested would be the full company number, the full company name, the new location that replaces the old one, and the signature of the CEO authorizing the changes.

Another important point is that entrepreneurs do not have to pay anything to submit the AD01 form. Access to the form is available online, which can be accessed here.


Business owners who wish to change their business address should also note that Companies House will only consent to changes if a complete mailing address is provided on the form. The new address must also be directly in the UK. The address must not be a PO box address either.


Once completed, the form should be sent by certified mail to Companies House, Crown Way, Cardiff, CF14 3UZ. However, if a business owner wants to present it online, they can. All you need to do is register with Companies House WebFiling.


Changing the registered office of a business is easy as long as the business owner provides the correct information. The online option makes things much faster and better for those who are too busy to send certified mail.



Can I Use Any Address As My Registered Office?

If you are providing a registered office for a limited liability company, it must be a real address with a zip code. Unfortunately, this means that you cannot use a mailbox. Boxing address and Companies House do not accept them. If you are one of the many companies that have an accountant as their general secretary, you can use your home office as the address for your accountant. Companies House uses your registered office address to send important communications. Therefore, it is important that you have access to this address to be able to retrieve all documents without risk of obsolescence. You should also make sure that the registered address is on all the business documents that you use.


Company records showing shareholders and directors are normally kept at the company's registered office (although they may be disclosed to Companies House if archived elsewhere). If the address changes, you must notify Companies House that the documents have been moved to a new location, along with the contact details of the new registrar.



Strategic Considerations for Choosing a Registered Office Address


Selecting the Right Registered Office Address

The choice of a registered office address is not just a legal formality; it plays a strategic role in a company's operations and public image. When selecting an address, consider the following factors:
