UKAS vs non-UKAS certification: what do you actually need?
This page exists for one reason: to help buyers make the right decision before spending money. A clear distinction between certification and accreditation is essential, especially in tenders and regulated or higher-risk supply chains.
The simple distinction
Certification is the audit and certificate issued to the client organisation.
Accreditation is the formal oversight of a certification body by a recognised accreditation body.
In the UK, UKAS is the national accreditation body. If a buyer says “UKAS-accredited”, that is a specific requirement and should not be blurred.
When non-UKAS may be proportionate
- The requirement says “ISO 9001 or equivalent”.
- The buyer mainly wants evidence of a functioning quality-management system.
- The sector is not regulated and the customer has not insisted on accredited certification.
- You need a proportionate, independently reviewed system to support customer confidence and operational discipline.
A practical view
| Requirement wording | Indicative route | Risk level for non-UKAS | Recommended action |
|---|---|---|---|
| Supplier must hold UKAS-accredited ISO 9001 certification. | Accredited route | High | Do not assume non-UKAS is acceptable. Seek buyer clarification only if a genuine equivalent route is allowed. |
| Supplier shall hold ISO 9001 or equivalent. | Non-UKAS may be proportionate | Moderate | Pair certification with an audit summary and supporting quality evidence. |
| Provide details of your quality-management arrangements. | Evidence pack may be sufficient | Low to moderate | Submit policy, process controls, audit evidence and improvement records. |
| Regulated, high-risk or highly scrutinised sectors | Usually accredited route preferred | High | Review carefully. Non-UKAS may not satisfy the market expectation. |
Red flags to avoid
- Blanket claims that a non-UKAS certificate is “the same as UKAS” in all circumstances.
- Instant or guaranteed certification without meaningful audit evidence.
- Overly vague scope wording such as “all business activities”.
- No verification register, no complaints route and no visible governance.
- Using logos, seals or wording that implies government recognition.
Safe wording for bids
Our quality-management system has been independently reviewed and certified by a non-UKAS certification provider against ISO 9001-aligned requirements. We understand this is not UKAS-accredited certification. Where UKAS-accredited certification is specifically required, we can provide additional documented quality evidence or pursue an accredited route as required by the contracting authority.
