DfE Construction Framework 2021 (DfE-specific, in extension), CCS RM6238 (Heat Networks and Building Energy, cross-public-sector), Pagabo (multi-sector), LHC (public-sector consortium). All four are commonly used for school decarbonisation.

DfE CF when the works are DfE-scope construction (new build, major refurbishment); RM6238 when the works are heat network or building energy specifically. Many MATs use both, lot-by-lot.
RM6238 includes ASHP and GSHP as dedicated lots. DfE CF includes fabric and major refurbishment. Pagabo and LHC carry decarbonisation lots that include the same kit.
Framework operator fees commonly sit at 1.5 to 2.5 per cent of project value. The contractor's overhead recovery via framework is broadly similar to non-framework procurement, plus a framework levy.
