The sign-in screen for the Companies House 'Find and update company information' service is set to change in late August 2026. GOV.UK One Login will become the main sign-in option for users accessing the service.
While existing users can continue to sign in with their current Companies House account details, this option will be located further down the sign-in page. All new users, however, will be required to use a GOV.UK One Login to access Companies House services.
Companies House has stated that in the future, all users will need to transition to GOV.UK One Login, with prior notice to be provided. This change specifically affects the sign-in process and does not involve identity verification.
GOV.UK One Login enables access to various government services using a single email address and password, incorporating multi-factor authentication via an authenticator app or SMS for enhanced security. The move to GOV.UK One Login for online services began in autumn 2024.
For teams currently sharing a Companies House account, it is advised to plan for managing access when GOV.UK One Login becomes compulsory. Each GOV.UK One Login must be linked to an individual with their own email address and phone number. To prevent disruption, each person requiring access should create their own Companies House account linked to their own GOV.UK One Login, as sharing an account after linking could trigger security controls.
