“We’re introducing a single sign-in that will make it easier and more secure for companies and business owners to access our services.

The move to GOV.UK One Login means companies of all sizes will benefit from a more secure, consistent way of accessing our 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.“
