Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, which (a) Departments, (b) arms length bodies and (c) Government programmes have (i) migrated to and (ii) plan to migrate to One Login.

All major government departments have committed to onboarding their services to GOV.UK One Login, and are actively developing delivery plans. They are supported by our Onboarding and Engagement team who share best practices and provide advice and assets to enable technical service teams to onboard their services smoothly.

As of December 2024, users can access over 50 government services across multiple government Departments, within GOV.UK One Login. The list of public-facing services can be found here: https://www.gov.uk/using-your-gov-uk-one-login/services.

Some services are still in an early testing phase and are currently available to only a select group of users, therefore not listed in the service list.

We expect to have onboard over 100 services next year, with more to follow. Future services to include those from HM Revenue and Customs, Department for Work and Pensions, Companies House, Office for Public Guardian, and the Department for Education.
