Supplying the NAO
The National Audit Office (NAO) spends over £30 million annually on externally procured goods, works and services. These include professional services – such as financial, research and legal services – as well as training, management consultancy, IT solutions, facilities management, and office supplies.
The NAO’s Central Procurement Team is responsible for sourcing goods, services, and works in accordance with UK public procurement regulations, internal policies, and recognised best practices.
How to do business with the NAO
Delta eSourcing system
Suppliers interested in working with the NAO must register – free of charge – onto the system used by our Central Procurement Team to advertise NAO procurement opportunities. Register for Delta eSourcing
Find a Tender Central Digital Platform
Suppliers must also register – free of charge – onto the central digital platform the UK’s official site for public sector contract notices. Suppliers can view and bid on contract opportunities published by contracting authorities, including the NAO. Register for Find a Tender
Important: Suppliers who registered on Find a Tender (FTS) before the Procurement Act 2023 came into effect on Monday 24 February 2025 must re-register before bidding for new contract opportunities. This is due to the launch of the Central Digital Platform (CDP), which replaced the previous FTS system and now requires suppliers to complete their organisational core information on the platform.
