Are you prepared for the change?
From 13 October 2025, Companies House will require all businesses to use a GOV.UK One Login to access WebFiling. 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 link your WebFiling account to a GOV.UK One Login in order to continue submitting filings.
If you currently share your WebFiling login with colleagues or team members, be aware that only one person can connect each WebFiling account to their GOV.UK One Login. Anyone else requiring access will need to create their own login, using a unique 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.
How to prepare
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 WebFiling is active and accessible. If you also use “Find and update company information,” use the same email address for both.
- Set up a GOV.UK One Login – If you don’t already have one, you can register early using the same email linked to your Companies House accounts to help make the transition 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 WebFiling account to GOV.UK One Login.
- Review access arrangements – If multiple people use the same WebFiling login, now’s the time to plan for each individual to have their own account going forward.
- 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 WebFiling after 13 October 2025, you’ll be redirected to connect your account with GOV.UK One Login.
