Three contracts were awarded under this contract for Supplier A (WSP), Supplier B (Buro Happold) and Supplier C (AtkinsRealis). Tiered contracts were placed in order to manage any conflict of interest of resourcing issues which Suppliers may have which may prevent them undertaking a commission. The GBE due diligence programme includes Technical due diligence as well as Commercial Financial and Management due diligence. The programme is PS10m ex VAT in total. Each of these contracts has a contract value of up to PS10m, but will each share a proportion of the programme budget as required. This was procured through the Department for Energy Security and Net Zero's Energy and Net Zero Professional Services Framework (\"ENZPS Framework\") Lot 2 and SD1 Policy and Strategy and SD 3 Energy Design and Delivery.
