NAS Certification for
Public Sector Contractors
Independent, evidence-based compliance certification for contractors working with central government, public bodies, and CCS framework supply chains.
Demonstrate Public Contracts Regulations compliance, Modern Slavery Act adherence, and GDPR standards to government procurement teams with independently verified certification.
Why It Matters
Public Sector Procurement Has the Highest Compliance Bar
Central government and public body procurement teams operate under Public Contracts Regulations 2015 and are subject to audit by the National Audit Office and parliamentary scrutiny. Their supply chains must meet the highest standards of legal compliance and ethical conduct.
NAS Gold certification provides independently assessed evidence across Public Contracts Regulations, Modern Slavery Act, Anti-Bribery Act, and GDPR — the core compliance areas that public sector PQQs require.
