Companies House web-filing to switch to GOV.UK One login
From 13 October 2025, Companies House will require all businesses to use GOV.UK One login to access web-filing. This change is part of a wider government move to introduce a single, more secure login system across all online services.
What’s changing?
From 13 October 2025, you’ll need to connect your web-filing account to GOV.UK One login before you can continue filing. If you share your web-filing account with others, only one person will be able to connect each web-filing account to their GOV.UK login. Anyone who shares access will need to create their own GOV.UK One login, using a different email address. This is part of a wider move as the government intends for GOV.UK One login to be increasingly used for accessing online services.
What you can do to get ready
To avoid last-minute issues, here are a few simple steps to take before October 2025:
- Check your email addresses – make sure the email you use for web-filing is current and accessible. If you also use “Find and update company information,” use the same email address for both.
- If you don’t already have one, you could set up a GOV.UK One login in advance, using the same email as your Companies House accounts. This will make connecting smoother.
- Check that you have the authentication code handy for each company you file for. You may need to enter it when you connect your web-filing account to GOV.UK One login.
- Review who has access – if your team shares a web-filing login, each person will need their own account going forward. Start planning how to manage this.
- Think about identity verification – while not compulsory until November 2025, directors and People with Significant Control (PSCs) can verify their identity early using GOV.UK One login.
If you try to sign into web-filing after 13 October 2025, you’ll be redirected to connect your account with GOV.UK One login.
