Compliance
Contractor assurance for procurement and delivery.

Assurance approach
Contractor assurance without the document chase.
Commercial clients need confidence that their contractor operates to recognised standards of safety, quality, environmental responsibility and professional competence. Public registers provide the starting point; supporting evidence is then shared through a controlled route.
- Public register links for current credentials
- Insurance, policies, RAMS and management information on request
- Competence, training, plant inspection and LOLER evidence
- Support for PQQs, tenders, audits and contractor onboarding
Assessed capability
