The Schools Procurement Unit (SPU) has a central role in communicating procurement requirements and opportunities to schools, driving and measuring compliance with central contracts and managing procurement data across the schools sector. Central contracts only exist for specific ranges of goods and services. Schools are free to procure goods and services not covered by central contracts from their traditional suppliers. Where a central contract exists, a school can procure outside the contract, if it can make a strong commercial case. The Manager of the SPU will provide procurement advice to schools and will assist schools to obtain the best value for money through centralised and aggregated procurement where appropriate.
