Cabinet Office

The UK government department responsible for supporting the Prime Minister and Cabinet, and for setting central procurement policy across the public sector, including through the Crown Commercial Service.

Role in Procurement

The Cabinet Office is the central government department that owns procurement policy for the UK public sector. It publishes statutory guidance, procurement policy notes (PPNs), and frameworks that contracting authorities across central government are expected to follow. It also sponsors the Crown Commercial Service (CCS), the executive agency that manages cross-government commercial agreements and framework contracts.

Following the Procurement Act 2023 (which came into force on 24 February 2025), the Cabinet Office took on responsibility for issuing the statutory guidance and secondary legislation that underpin the new regime, replacing the regulatory architecture built around the Public Contracts Regulations 2015.

Key Functions

• Policy ownership: Sets mandatory and advisory procurement policy through PPNs, which central government departments must implement and which wider public bodies are encouraged to adopt.
• Transparency and reporting: Oversees the central digital platform (Find a Tender and Contracts Finder) through which public contract notices must be published.
• Commercial capability: Runs programmes to professionalise the Government Commercial Function (GCF), including the Government Commercial Organisation (GCO) which manages senior commercial talent across departments.
• Supplier relations: Leads strategic supplier management for the most significant government suppliers and chairs the Government's strategic supplier engagement forums.

Practical Relevance for Suppliers

Suppliers bidding for central government contracts need to understand that Cabinet Office guidance shapes how contracting authorities interpret procurement rules. PPNs on topics such as prompt payment, carbon reduction plans, and exclusion grounds directly affect bid requirements and contract conditions. Monitoring Cabinet Office publications is therefore a practical necessity for suppliers active in the public sector market.

Limits of Jurisdiction

The Cabinet Office's direct authority primarily covers central government departments and their arm's-length bodies. Local authorities, NHS bodies, and devolved administrations operate under the same legislation but are not directly managed by the Cabinet Office, though they frequently adopt its guidance voluntarily.
