From 13 October 2025, the way you log into Companies House WebFiling is changing. You will need to use GOV.UK One Login to access your WebFiling account. This means that the old style logins will no longer work. When you next try to sign in after that date, you will be prompted to link your existing WebFiling account with a GOV.UK One Login account before you can continue filing.
Why this change is being made
The government is moving towards a single, more secure login system across all GOV.UK services. GOV.UK One Login will allow you to use the same details for multiple services. It comes with two factor authentication and the option to verify your identity for Companies House. Over time, GOV.UK One Login will replace systems such as Government Gateway.
What you should do now
There are some steps that businesses and company directors can take before October to make the change smoother.
- Check and update your email address. If you also use the “Find and update company information” service, make sure both accounts use the same email. This will make linking the accounts simpler.
- Create a GOV.UK One Login account in advance, preferably with the same email address.
- Review your list of companies in WebFiling. If there are companies that you no longer file for, remove them from your list to avoid confusion.
- Make sure you have your authentication codes to hand. You may need them when linking your account.
- If you share a WebFiling account, only one person can link it to GOV.UK One Login. Other users will need to set up their own One Login accounts with different email addresses. This means they will lose access to the shared account.
Looking ahead
From 18 November 2025, new legal requirements mean that all directors and people with significant control (PSCs) will need to verify their identity with Companies House. You can complete this through GOV.UK One Login now or wait until later in the year.
Conclusion
The move to GOV.UK One Login is designed to provide a safer and more joined up experience when using government services. By preparing now, making sure your email and login details are ready, and checking your company authentication codes, you can ensure that the October switch does not disrupt your filing.
