  5. PPN 012: Security Classifications Policy
The Procurement Policy Note (PPN) on the Government Security Classifications Policy (GSCP) 2023 provides updated guidance on handling sensitive government information within public sector contracts. Updated in February 2025, it applies to central government departments, executive agencies, non-departmental public bodies, and NHS organisations, with recommendations for other public sector bodies managing HMG data. The PPN aligns with the Procurement Act 2023 and Procurement Regulations 2024, effective from 24 February 2025. Key updates include refinements to classification tiers (OFFICIAL, SECRET, TOP SECRET), baseline security behaviors, and new guidelines for additional markings and remote working. In-scope organisations must ensure appropriate protective security controls are in place and communicate updates to suppliers.
