In brief: AI TrustMark describes itself as the independent evidence layer for AI services. It checks suppliers, products and customer evidence, then publishes what was examined, how deeply and when. It is operated by AI Build Group Ltd, which it discloses, and it is not a certification scheme. Discuss AI assurance with us on Stand B501 at The Business Show London 2026, ExCeL London, on 11–12 November 2026.
What is AI assurance?
AI assurance covers the techniques used to check, and communicate evidence, that AI systems are developed and deployed safely and responsibly. The UK government's Introduction to AI assurance explains the key concepts, and the NIST AI Risk Management Framework is a widely used reference for AI risk management.
What should buyers ask before adopting an AI service?
- Who is accountable for the tool and its outputs?
- How are its decisions or recommendations explained?
- What data does it use, and where is it processed?
- Where does human oversight sit?
- How are risks monitored once it is in use?
Responsible AI adoption means getting evidence for those answers rather than relying on sales claims.
What does AI TrustMark publish?
- Free directory listings that suppliers can create or claim.
- Published customer reviews with an explicit verification level. Suppliers cannot pay to remove a negative review or edit customer text.
- Bronze, Silver or Gold assurance, describing investigation depth: external evidence, then operational evidence, then technical examination where access is granted.
- An Assurance Score from 0 to 100 for the named scope, with a Low, Elevated or High Impact classification.
- Reusable procurement evidence, so a supplier's evidence can be checked once and reused across tenders.
The levels are not a league table: deeper investigation is not a claim that one supplier is better than another. Read our AI TrustMark exhibitor article for more.
Is AI TrustMark a certification?
No. AI TrustMark is not a government scheme, not a UKAS-accredited certification body and not a substitute for ISO/IEC 42001 certification or a buyer's own legal obligations. Its assurance levels and scores are evidence to inform procurement and risk decisions.
