Who pays now
Schools and MATs fund feasibility from internal reserves or as part of a wider estates capital plan. Local Net Zero Hubs [DESNZ] provide free pre-bid advisory but do not write feasibility studies.
What a PSDS-grade study contains
- Site survey and asset-by-asset condition.
- Heat-loss model in W/m² for each treated building.
- Proposed measure schedule with manufacturer SCOP/efficiency.
- Lifetime kgCO2e calculation and Grant Carbon Cost number.
- Capital cost estimate with procurement route.
- Construction programme aligned to the Phase delivery deadline.
Cost and time
Feasibility and technical-survey fees are quoted per project, not published as a standard rate. As an order-of-magnitude planning band, budget around £8k to £35k for a school-scale study depending on site count and survey complexity, with larger MAT bundles higher; timeline is usually 6 to 10 weeks from kick-off. Confirm against your own consultant quotes before relying on the figure.
Feeds the Salix portal
Feasibility output is the evidence pack the Salix portal application points at. The portal does not redo the maths; it tests it.
