Changes to criteria, standards transitions, and notices concerning accredited bodies.
The register can now be searched directly from this website. Any TQC certificate number can be entered on the verification page and resolved against the register without an account.
Certificates issued from this date carry a QR code pointing at the verification URL for that specific number, so a recipient sees the result without typing anything. Written verification statements on letterhead remain available free of charge for tender and audit purposes.
The transition period from ISO/IEC 27001:2013 to ISO/IEC 27001:2022 ended on 31 October 2025. Certificates issued against the 2013 edition are no longer current, and accreditation is not offered against that edition.
Certification bodies within the management system programme should ensure their own scope documents, marketing material and certificate templates refer to ISO/IEC 27001:2022.
OHSAS 18001 was withdrawn in March 2021 and replaced by ISO 45001:2018. Accreditation for occupational health and safety management system certification is available against ISO 45001:2018 only.
This notice is retained here because material referring to OHSAS 18001 remains in circulation. A body offering certification against a withdrawn standard should expect that to be raised at assessment.
Send us your details and we will come back with the criteria that apply to you, not a brochure.
