Scope multiple AI products before budgeting

You pay for the examination, not the result. Review codes collect verified customer reviews; verified stars decide directory order.

How much does independent AI assurance cost?

The price of an AI assurance examination depends on the scope, the evidence to be examined and the technical complexity of the named AI product or supplier. There is no reliable universal fee for every AI deployment. Use the current prices and scope options displayed on this page for the available AI TrustMark examination depths, and confirm any additional services before purchasing.

Payment is for the examination, never a guaranteed TrustMark outcome, favourable score, verified customer review or directory ranking.

What changes the cost of AI assurance?

| Cost or scope factor | Why it matters to the examination | |---|---| | Product and supplier scope | One well-defined AI service differs from an integrated system spanning several products, models or legal entities | | Examination depth | External/public evidence, internal governance documents and technical architecture or testing require different levels of access and investigation | | Evidence readiness | Current, attributable and complete documents are easier to examine than fragmented or missing evidence | | Model and data dependencies | Third-party foundation models, retrieval, agents, subprocessors and international data flows may broaden the questions | | Technical testing | Representative evaluation, security testing and inspection of agent permissions may require specialist effort | | Reassessment | Major changes in model, provider, intended use or controls may require evidence refresh or further review |

The Bronze, Silver and Gold labels explain depth of investigation, not grades for the supplier, the likelihood of receiving a certificate or a standardised quality score. Review the current on-page pricing options to understand what is included.

What is included in an independent AI assessment?

An assessment should identify the named organisation or product being examined, the evidence requested and reviewed, the examination depth, dates, findings and limitations. It should distinguish claims supported by documents or demonstrations from those independently corroborated. The exact deliverables depend on the agreed scope.

For the evidence approach see AI TrustMark's methodology, how the assessment works and independent AI assurance.

AI governance versus AI assurance: what are buyers paying for?

AI governance is the management framework through which an organisation assigns accountability, policies, controls, oversight and ongoing monitoring for AI use. AI assurance is the examination or evidence-based evaluation of claims about an organisation, system or control within a defined scope. A governance programme can be assessed, but buying governance consultancy is not the same as purchasing independent examination.

The UK government's introduction to AI assurance gives background on assurance concepts. Neither that guidance nor AI TrustMark's references imply a government endorsement.

How should procurement teams compare AI assurance providers?

Ask each provider to specify its role, competence, independence, evidence-access requirements, method, deliverables, limitations, reassessment conditions, fee basis and any accredited certification claims. Verify the relevant accreditation and certificate scope rather than equating management-system certification with named-product evaluation.

The UK AI assurance provider comparison explains the different categories; ISO 42001 versus independent product assurance clarifies which evidence each may cover.

When is a lighter or deeper examination appropriate?

A relatively narrow, low-impact use with readily available external evidence may justify a more limited initial review. A service handling sensitive data, relying on consequential automated decisions, or invoking powerful external tools may warrant deeper governance and technical examination. Choose scope according to the buyer’s actual risks and intended use, not the promise of a better badge.

Use the AI vendor due diligence questionnaire to prepare the evidence, then start an assessment when ready.

Frequently asked questions about AI assurance pricing

Is the fee a payment for certification?

No. Paying for AI TrustMark examination does not purchase a predetermined result, ISO/IEC 42001 certification, UKAS accreditation or government approval.

Does a higher examination depth improve directory ranking?

No. Examination depth and directory ranking are separate. Payment does not buy reviews, star ratings or rank position. See independence.

Can I compare a low-cost governance review with a technical AI assurance examination?

Only after confirming what evidence and systems each covers. Compare deliverables and scope rather than headline price alone.

Can pricing change if the product or model changes?

A material change may affect the scope of further examination or reassessment. Confirm the terms and any additional fee before commissioning additional work.
