Find out who can certify digital identity services during the pilot process, and more about the approval and accreditation process.

▤ Verbatim text from source document

Introduction

Service providers must use an approved conformity assessment body (CAB) if they want to become certified against the UK digital identity and attributes trust framework or relevant supplementary codes.

The Office for Digital Identities and Attributes (OfDIA) is currently operating a pilot certification process. It approves CABs to participate in the pilot and to certify services.

Approved conformity assessment bodies

The approved CABs under the pilot are:

Only approved CABs can offer certification against the trust framework or supplementary codes. Certificates of conformity from unapproved bodies are not valid.

Accreditation of conformity assessment bodies

The UK Accreditation Service (UKAS) provides accreditation to certification bodies in the UK. We are working with CABs to enable them to become accredited by UKAS by the time the pilot ends. We expect the pilot to finish in 2025.

CABs will need to be accredited by UKAS and approved by OfDIA to continue certifying services once the pilot has ended.

More detail can be found on the UK Accreditation Service website.

How to apply to become an approved Conformity Assessment Body

If you are a CAB and want to be approved to certify services against the UK digital identity and attributes trust framework, please contact us at correspondence@dsit.gov.uk.

Consultancy and other advisory services

OfDIA has not approved or endorsed any organisation to provide consultancy, advice or gap analysis to service providers wishing to certify against the trust framework or supplementary codes.
