What is the NM01 Form?

The NM01 form is a statutory form used by companies registered in the UK to notify the Companies House of a change in their registered office address. The registered office address is a critical piece of information for any company, as it is the official address where legal documents, notices, and correspondence from regulatory bodies are sent. Changing this address requires formal notification to ensure that all communications are received promptly and that the company complies with legal requirements.

Filing the NM01 form is not merely an administrative task; it holds significant legal and operational importance for businesses.

Significance of the NM01 Form

Notifying the Companies House of a change in the registered office address can lead to severe consequences, including fines and legal disputes. Additionally, a company’s registered office address is publicly accessible information, meaning inaccuracies can impact the company’s reputation and ability to receive crucial documents.

Steps to Complete the NM01 Form

Navigating the NM01 form requires careful attention to detail. Here is a step-by-step guide to help you through the process:

The first step is to obtain the NM01 form, which is available for download on the Companies House website. Ensure you have the most recent version of the form to avoid discrepancies.

The form begins with sections for your company’s basic information. You will need to provide your company name and registration number. Double-check this information to ensure it matches precisely with the details held by the Companies House.

Next, you will need to enter the new registered office address. This address must be a physical location within the United Kingdom and cannot be a PO Box. The address should be complete and accurate to ensure all future correspondence is correctly delivered.

An authorized person within the company must sign the NM01 form. This could be a director, company secretary, or any other individual with the authority to make changes on behalf of the company. The signature signifies that the information provided is accurate and that the change has been duly approved by the company’s board or appropriate authority.

Once the NM01 form is completed and signed, it must be submitted to the Companies House. This can be done online or by post. Online submissions are generally faster and more convenient. If you choose to submit by post, ensure that the form is sent to the correct address provided by the Companies House.

Common Mistakes to Avoid

Completing the NM01 form accurately is crucial. Here are some common mistakes to avoid:

Ensure that all information, especially the new registered office address and company registration number, is accurate and up-to-date. Even minor errors can result in delays or rejection of the form.

Make sure all sections of the form are filled out completely. An incomplete form will be returned, causing delays in updating your registered office address.

Only authorized individuals should sign the NM01 form. Submissions with unauthorized signatures will not be accepted, leading to further complications.

Benefits of Updating Your Registered Office Address

Updating your registered office address using the NM01 form comes with several benefits:

Ensuring that your registered office address is up-to-date helps maintain compliance with UK company law. This can prevent legal issues and potential fines.

A correct registered office address ensures that all essential documents and notices are received promptly. This includes communications from the Companies House, HMRC, and other regulatory bodies.

An accurate and updated registered office address can enhance your company’s professional image. It shows that your business is well-organized and compliant with legal requirements.


The NM01 form is an essential document for any UK-registered company that needs to change its registered office address. Understanding its importance and following the correct steps to complete and submit the form can save your business from legal complications and ensure smooth communication with regulatory bodies.
