For those who operate a limited company, Companies House (CH) are introducing a single sign-in to 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 are to benefit from a more secure, consistent way of accessing CH services – giving greater assurance about who is setting up, running and controlling companies in the UK.
From 13th October 2025, directors and officers will need to use GOV.UK One Login to sign in to their businesses Companies House WebFiling account.
From this date, when they sign in to WebFiling, they will be prompted to connect their WebFiling account to GOV.UK One Login. They will not be able to access WebFiling without connecting to GOV.UK One Login.
CH began moving their 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 identitication 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.
Get ready for the change
To make sure they can still access their account after the change and that saved information wis still be available:
- They need to make sure the email address used to sign in to WebFiling is up to date and they have access to it – they can update the email address by selecting ‘Change account details’ after signing in to their WebFiling account
- if they also have a Companies House account for Find and update company information, they must make sure they can use the same email address for both accounts – they can change either the email address used for your Companies House account or the email address used to sign in to WebFiling
- if they do not have a GOV.UK One Login, they should consider creating one before 13th October 2025 using the same email address as their WebFiling account
- if they have a Companies House account for Find and update company information, they can consider connecting this with GOV.UK One Login now
- they can check the list of companies they are authorised to file for in their WebFiling account – go to the ‘Your companies’ page and remove any companies they can no longer file for
How to connect to a WebFiling account to GOV.UK One Login on or after 13th October 2025
When they try to sign in to WebFiling from 13th October 2025, they will be redirected to connect your account with GOV.UK One Login.
If they:
- have a GOV.UK One Login, they will be able to sign in and connect to their account
- if they do not have a GOV.UK One Login, they will be prompted to create one
- have a Companies House account for Find and update company information that they have not connected with GOV.UK One Login, they will be able to connect both accounts at the same time
They may need to enter each company’s authentication code toconfirm that they are still authorised to file for the company.
They do not need to verify identity to connect your WebFiling account with GOV.UK One Login.
If sharing a WebFiling account with others
Only one person can connect each WebFiling account to their GOV.UK One Login.
Anyone who shares access to these accounts will need to create their own GOV.UK One Login, using a different email address. They will no longer be able to access the information in the accounts.
Identity verification
From 18th November 2025, identity verification will become a legal requirement for new and existing company directors and people with significant control (PSCs). Individuals can voluntarily verify their identity now.
They can verify identity for Companies House:
- using GOV.UK One Login through the ‘Verify your identity for Companies House’ service
- through an Authorised Corporate Service Provider, for example an accountant or solicitor
