Companies House online filing moves to GOV.UK One Login

Businesses filing documents with Companies House online will be able to connect their accounts to the GOV.UK One Login.

The move to a single sign-in via the GOV.UK One Login means companies of all sizes will benefit from a more secure, consistent way of accessing government services, and gives authorities greater assurance about who is setting up, running and controlling companies in the UK.

From 13 October 2025, businesses will need to use GOV.UK One Login to sign in to a Companies House WebFiling account. From this date, when signing in to WebFiling, account holders be prompted to connect your WebFiling account to GOV.UK One Login. Businesses will not be able to access WebFiling without connecting to GOV.UK One Login.

Companies House began moving online services to GOV.UK One Login in autumn 2024, beginning with the option to connect an existing account. Over time, GOV.UK One Login will replace all other ways to sign in to services on GOV.UK, including Government Gateway. 

To make sure you can still access your account after the change and that your saved information will still be available:

• make sure the email address you use to sign in to WebFiling is up to date and you have access to it – you can update the email address by selecting ‘Change account details’ after signing in to your WebFiling account
• if you also have a Companies House account for Find and update company information, make sure you use the same email address for both accounts – you can change either the email address you use for your Companies House account or the email address used to sign in to WebFiling
• if you do not have a GOV.UK One Login, consider creating one before 13 October 2025 using the same email address as your WebFiling account
• if you have a Companies House account for Find and update company information, consider connecting this with GOV.UK One Login now (if you have not already)
