RM6238 lots carry both Tier 1 ESCOs and Tier 2 regional contractors with specific schools experience. The framework's lot-by-lot supplier list is published on CCS.
RM6238 is the right route when the works are specifically heat network or building energy; DfE CF is the right route when the works are broader construction. Both can be used on the same MAT programme.
Direct award via RM6238 is generally faster than competitive tender. Direct award is appropriate when the supplier's lot pricing meets the buyer's value-for-money tests.
