Verify certification and accreditation correctly
ISO 9001 Accredited Companies In The UK
A company is normally certified to ISO 9001 by a certification body. UKAS accredits competent conformity-assessment bodies, so verification should connect the company certificate to the issuing body and its accreditation scope.
Practical comparison
What a credible verification should connect
| Evidence | What to match | Why it matters |
|---|---|---|
| Company certificate | Legal entity, address, scope, standard and certificate number | Confirms what is represented as certified. |
| Certification body | Issuer name and contact details | Identifies who made the certification decision. |
| Accreditation | Accreditation body, standard and certification-body scope | Shows whether the issuer is accredited for the relevant activity. |
| Status and dates | Issue, expiry, suspension or withdrawal information | A genuine document may no longer be current. |
| Sites and activities | Locations and operations included in scope | Certification does not automatically cover every group company or site. |
Step by step
How to verify a UK ISO 9001 certificate
- 1
Obtain a clear certificate showing the company identity, number, scope, standard, issuer and dates.
- 2
Check the company name and address against the supplier or contract entity.
- 3
Identify the certification body and verify its relevant accreditation.
- 4
Confirm status with the certification body or available accredited database.
- 5
Document the verification date and resolve scope, site or status discrepancies before approval.
Quality control
Avoid common verification mistakes
- UKAS accreditation certificates belong to accredited organisations, not automatically to every company they certify.
- A logo by itself is not proof of current certification.
- Certification scope may be narrower than the supplier’s full range of services.
- A missing online result requires follow-up; it is not by itself final proof of invalidity.

Does UKAS certify companies to ISO 9001?
UKAS is the UK national accreditation body. Certification bodies certify companies; UKAS may accredit those certification bodies for defined activities.
Is an ISO 9001 logo enough to verify a supplier?
No. Request the certificate and match the legal entity, scope, sites, standard, certificate number, issuer and current status.
What if the certificate is not found online?
Ask the issuing certification body to confirm the certificate and contact the relevant accreditation body when necessary. Database coverage and public visibility can vary.
