Question to the Department for Science, Innovation & Technology:

To ask His Majesty's Government why the GOV.UK One Login digital app lost its certification under the Digital Identity and Attributes Trust Framework, what is its current certification status and whether it will be ready to manage the Companies House identity verification requirements that come into force on 18 November

In April 2025, GOV.UK One Login’s Trust Framework certification was suspended due to a supply chain issue where one third party allowed their certification to lapse. This was not due to any change in GOV.UK One Login’s product, approach, or security. GOV.UK One Login is working to recertify as a priority.

Companies House onboarded to GOV.UK One Login in March 2025. We have been supporting Companies House users since then, and are fully prepared to support the mandatory Companies House requirements that take effect on November 18th. Certification to the Trust Framework is not a necessary condition for this.
