Certification Body Accreditation

Providing confidence in the safety and reliability of accredited certification activity

Accreditation demonstrates to the marketplace that certification bodies are technically competent to audit and certify activity in accordance with the requirements of national and international standards and regulations.

Users of accredited certification services can be confident in the quality of the processes used, the competence of the staff and the reliability and accuracy of results. Increasingly public and private organisations are specifying accredited certification in contracts to ensure traceability of complex supply chains. By demonstrating your technical competence through accreditation, you can differentiate yourself from your competitors.

Only UKAS accredited certificates include the UKAS accreditation symbol. The symbol has a dual role; it enables certification bodies to show their competence and allows consumers of certification services to easily recognise quality providers.

UKAS Training Academy

To support our accreditation work, the UKAS Training Academy offers a range of public and on-site training courses. Our portfolio of courses provide UK & overseas delegates with knowledge and best practice of accreditation practices and conformity assessment systems.
