Retrofit & Decarbonisation

PAS 2035 retrofit and decarbonisation works across council and NHS estates. Fabric-first insulation, heat pumps, ventilation and PV — delivered against PSDS, SHDF and Warm Homes funding windows.

PAS 2035 delivery that hits the funding window.

Fabric-first measures, heat pumps, ventilation and PV delivered under a TrustMark-registered PAS 2035 process — with a retrofit coordinator on staff who understands SHDF and PSDS evidence requirements as well as the install.

“They understood the funding rules as well as the install. We hit the SHDF deadline because of that.”
