What is the difference between certification and accredited certification?

The IT Governance service centre receives a large number of questions every day. One of the most common questions we receive is about the difference between certification and accredited certification.

Understanding the difference between the two is vital for organisations that are embarking on an implementation project.


Certification is the procedure by which a third party gives written assurance that a product, process, system or person conforms to specified requirements

Accredited certification

An accredited certification can only be performed by a certification body that has been formally recognised by an accreditation authority. This accreditation attests to the technical and organisational competence of the certification body to carry out a specific service in accordance with the standards and technical regulations as described in their scope of accreditation.

The United Kingdom Accreditation Service (UKAS) is the sole national accreditation body recognised by the UK Government.
