What does UKAS accreditation tell you?

Accreditation checks the technical competence of the body that audits and certifies you. UKAS lists an accreditation route for bodies that certify information security management systems to ISO/IEC 27001.

Keep the jobs separate when asking for a quote. You want to know who will issue the certificate and whether their UKAS record covers the work you are buying.

How do you search the directory?
