11 UK procurement entry points · 8 procurement priorities · 6 DEFONEOS MCPs · Cabinet Office CCS / GCF / NHS Supply Chain backbone
UK public sector procurement is undergoing its largest transformation since the EU exit, governed by the Procurement Act 2023 (in force October 2024), the Cabinet Office Central Government Commercial Function, the Crown Commercial Service (CCS) which manages £18bn+ of common goods/services spend, the Government Commercial Organisation (GCO), the Crown Commercial Service framework portfolio (G-Cloud 14, Technology Products & Associated Services, Management Consultancy 4, NHS LAV, etc.), and the National Procurement Policy Statement (NPPS) 2024. The Procurement Act 2023 replaced 4 EU-derived regimes with a single unified regime, introduced the Competitive Flexible Procedure, mandated transparency notices on Contracts Finder / Find a Tender, and created the Procurement Review Unit with debarment powers. The NHS Supply Chain Coordination manages £9bn+ of NHS goods. Local authorities spend £70bn+ on procurement annually. DEFONEOS delivers the UK's first open-source Sovereign Public Services OS purpose-built for procurement transformation — BFT-governed tender evidence, sovereign supplier provenance, open competition data infrastructure, and AI-assisted procurement intelligence.
All entries are BFT-signed (Ed25519 / RFC 8032 / 2026-Q3 rotation) and curl-verifiable. Per-entry contacts sourced from Cabinet Office CCS + Government Commercial Function + CCS frameworks + NHS Supply Chain + DLUHC Local Government + Crown Commercial Service (2026-Q1).

⚠️ HARD RED-LINE: DEFONEOS handles OFFICIAL and OFFICIAL-SENSITIVE procurement data ONLY. No classified defence procurement data. No procurement fraud facilitation (bid-rigging, cartels, conflicts of interest). No supplier bribery or corruption data exposure. No market manipulation through AI procurement intelligence. No personal-surveillance patterns. AI supports tender integrity verification, supplier due diligence, supply chain transparency, social value auditing, and procurement data infrastructure — never fraud facilitation, individual supplier targeting, or competitive market manipulation. All tender evidence is BFT-governed with 23/33 quorum and independently verifiable. DEFONEOS strictly supports the Procurement Act 2023 transparency principles, the National Procurement Policy Statement, and the Cabinet Office Conflict of Interest guidance.
