What is an AI procurement evidence pack?

It is a controlled record that links supplier, product, security, privacy, governance and customer evidence to procurement requirements. Each item should show its scope, source, verification status, date and any unresolved gap so buyers can distinguish checked evidence from supplier claims.

What does AI TrustMark independently verify?

Depending on scope, verification can cover supplier identity, product and model dependencies, security and privacy evidence, governance and operational controls, customer relationships, current assurance status and evidence provenance. The record states what was checked rather than implying that every control has been verified.

Does AI TrustMark replace a buyer’s due diligence?

No. AI TrustMark provides an independent verification layer for AI procurement. It can reduce repeated baseline due diligence, but it does not replace the buyer’s decision, legal obligations, eligibility assessment, evaluation or procurement process.

Can the evidence pack be reused across tenders?

Yes, where the evidence remains current and applies to the same supplier, product and scope. Reuse can reduce repeated questionnaires, but buyers should still request contract-specific evidence and recheck material changes, expired evidence and higher-risk use cases.

How does PPN 017 relate to the procurement process?

PPN 017 helps public-sector buyers identify AI use in procurements and service delivery. It is a transparency trigger, not a complete due-diligence framework, award criterion or guarantee of Procurement Act eligibility. See the PPN 017 procurement guide for the practical questions.

Does AI TrustMark guarantee Procurement Act eligibility or contract award?

No. Independently verified evidence can support a buyer’s record, but eligibility, evaluation, framework admission, legal compliance and contract award remain the buyer’s decisions. AI TrustMark does not endorse suppliers or guarantee an award.

What happens if supplier evidence is incomplete?

Gaps stay visible. The pack should record missing, expired, out-of-scope or unverified items rather than filling them with supplier claims. Incomplete evidence is a decision input, not a reason to invent assurance.

Where is the AI procurement checklist?

The compact list is the AI supplier due-diligence checklist at /guides/ai-supplier-due-diligence-checklist. This page explains the evidence pack those checks sit inside. AI TrustMark is not an AI procurement certification. The comparison with ISO/IEC 42001 is at /assurance/iso-42001. AI TrustMark is not an ISO/IEC 42001 certificate, UKAS accreditation or government approval.

What procurement work is free versus paid?

Free: the route recommendation, indicative complexity, framework checks and an information checklist. Paid professional work includes tailored RFI/RFP/ITT documents, evaluation matrices, evidence mapping, supplier assessments, contract schedules, procurement packs, deployment assurance and monitoring or reassessment.

Tender & procurement evidence pack

AI procurement due diligence and independent vendor verification

AI TrustMark independently verifies AI supplier, product and customer evidence so buyers can run due diligence once and reuse a controlled record across procurements. It does not replace the buyer’s award decision or legal duties.

Editorial last reviewed 2026-10-10

The compact list is the AI supplier due-diligence checklist. Dated source evidence is explained in AI vendor due diligence. AI TrustMark is not an AI procurement certification; see ISO/IEC 42001.

Customer-review ranking, the Assurance score and procurement evidence work are separate. Payment never buys stars, directory position or a predetermined assurance outcome.

AI TrustMark is an independent verification layer for AI procurement, supplier due diligence and vendor verification. It checks supplier, product, security, privacy, governance and customer evidence, then maps that record to buyer requirements. The crosswalk does not guarantee eligibility or a contract award.

Find the right procurement route first

If you are not sure whether you need discovery, specification, a procurement pack, supplier evaluation, due diligence, contract controls, deployment assurance or monitoring, start with the AI Procurement Route Finder.

The route finder asks a short adaptive set of questions and gives you a free triage result containing:

the recommended procurement route;
an indicative complexity level;
framework and specialist checks to consider; and
an information checklist showing what to assemble next.

It is designed to scope the next piece of work. Tailored procurement packs, evidence matrices, supplier assessment, contract schedules, deployment assurance and monitoring remain professional services.

AI Procurement Knowledge Base

Use the AI Procurement Knowledge Base to work through the full buying lifecycle: Plan → Specify → Evaluate → Contract → Deploy → Monitor.

The knowledge base translates primary-source guidance — including PPN 017, the UK Government AI Playbook, the 2026 DSIT AI Risk Management Toolkit and NCSC secure-AI guidance — into practical buyer questions, evidence requests and monitoring actions.

Use the AI Procurement Framework Crosswalks to navigate UK Government guidance, NCSC security, ICO data protection, NIST AI RMF, the EU AI Act and ISO/IEC 42001 without treating those frameworks as interchangeable certifications.

Start with the AI Supplier Due-Diligence Checklist, PPN 017 explained for AI procurement, or the 2026 UK AI Risk Management Toolkit for procurement.

AI TrustMark provides an independent verification layer; it does not replace the buyer's procurement process, legal obligations or award decision.

For buyers

Shorten baseline due diligence.

Start with a structured, independently verified pack covering supplier identity, product controls, customer evidence and current certificate status. Request contract-specific evidence only where the reusable record does not answer the requirement.

For suppliers

Prove the baseline once.

Maintain one controlled assurance record with explicit scope, evidence permissions, validity periods and material-change triggers, then reuse it across bids and buyer questionnaires.

The pack structure below is a template, not a CERTIFIED vendor record. Human-verified evidence is added only after examination.

How procurement packs work Start an assessment →

Procurement pack structure: requirement, control, evidence grade, date checked, gap
Requirement	Control	Evidence grade	Date checked	Gap
Supplier identity and named product scope	Legal entity, domain and product boundary	—	—	Awaiting assessment
Security, privacy and AI governance baseline	Mapped TrustMark controls for the chosen depth	—	—	Awaiting assessment
Customer and implementation evidence	Human-verified V1+ reviews where published	—	—	Awaiting published evidence
Certificate status and expiry	Live /verify record	—	—	No live certificate

Government requirements crosswalk

One requirement. One evidence reference.

The crosswalk records the government requirement, the applicable AI TrustMark control, the evidence inspected, its evidence grade, the date checked and any unresolved gap. Procurement teams can accept, challenge or supplement each item without asking the supplier to recreate the whole baseline submission.

What the shortcut removes

— Repeated supplier identity and baseline control questionnaires
— Re-uploading the same policies and technical evidence for each opportunity
— Unstructured claims with no evidence provenance or verification date
— Manual comparison of equivalent questions across buyer frameworks

What the buyer still decides

— Whether the product is suitable for the intended use and risk
— Contract-specific security, legal, commercial and data requirements
— Whether further testing, DPIA work or specialist assurance is required
— Eligibility, evaluation, framework admission and contract award
