The Government are introducing a single sign-in that will make it easier and more secure for companies and business owners to access their services.

The move to GOV.UK One Login means companies of all sizes will benefit from a more secure, consistent way of accessing their services – giving greater assurance about who is setting up, running and controlling companies in the UK.

From 13 October 2025, you’ll need to use GOV.UK One Login to sign in to your Companies House WebFiling account.

From this date, when you sign in to WebFiling, you’ll be prompted to connect your WebFiling account to GOV.UK One Login. You will not be able to access WebFiling without connecting to GOV.UK One Login.

The Government began moving online services to GOV.UK One Login in autumn 2024, beginning with the option to connect a Companies House account, the account used to sign in to the Find and update company information.

Benefits of GOV.UK One Login

GOV.UK One Login provides:

  • Access to multiple government services with one set of sign in details
  • Enhanced security with two-factor authentication
  • The option to use GOV.UK One Login to verify your identity for Companies House

Over time, GOV.UK One Login will replace all other ways to sign in to services on GOV.UK, including Government Gateway.
