Certain company changes—like a new registered address, email, or director—must be reported to Companies House promptly. Failure to update records risks penalties and non-compliance with UK company law.

These include the following:

Updating the registered office address

If you change your company’s registered office, you are required to notify Companies House. Note that the new address must remain within the same part of the UK where your company was initially registered. For instance, a company incorporated in England and Wales must maintain its registered address within those regions.

Your company’s new address will only be officially changed once Companies House has registered the update. Once this is done, they will automatically inform HMRC.

Changing the registered email address

If you need to update your company's official email address, this involves a separate process. To change a registered email address a request should be made at https://find-and-update.company-information.service.gov.uk/registered-email-address

Other changes that require notification

You should inform HMRC if there are updates to your contact information, business name, or if you appoint an accountant or tax adviser.

You must also notify Companies House within 14 days of any changes involving:

• Company directors or their personal details
• Individuals with significant control (PSC)
• The address where you keep your records, and which records you keep
• Appointment or resignation of company secretaries

Finally, if you issue new shares, Companies House must be notified within a month.

You can report these changes using the Companies House online service or by submitting the appropriate paper forms.
