Decarbonisation does not unlock CIF on its own. CIF funds condition-led replacement. PSDS funds decarbonisation uplift. A boiler that is condition-failed and being replaced with a heat pump can sit in CIF; a working boiler being replaced with a heat pump cannot.

Does decarbonisation tilt the CIF score?
When should a bid use CIF vs PSDS?
Heat-pump replacement under CIF?
Glazing / fabric upgrade under CIF?
How is energy benefit evidenced?
A useful framing: the condition pack drives CIF, the energy uplift drives PSDS. Bids that try to use the energy uplift to justify the condition replacement get marked down on need.
Trusts increasingly stack a CIF condition-led bid with a PSDS uplift bid. The two grants are administered separately.
