Eligibility and carbon claim
BMS savings come from reduced over-heating, better setbacks, demand-controlled ventilation. Claim is typically 8-15% on heat and 5-10% on electricity.
£ band
£25k to £80k per school for a controls upgrade, depending on plant complexity and number of zones.
£/tCO2e
Often the lowest £/tCO2e in the bundle (£100-200) but the absolute tonnage is modest. Best framed as enabling for a heat-pump or fabric programme.
Reporting interaction
BMS that includes sub-metering on the new heat-pump and fabric-treated zones pays back at the reporting stage (reporting page). Without it, attributing measured kgCO2e to the funded measure is impossible.
Delivery partners
Typical PSDS BMS pipeline: Equans, Mitie, in-house FM teams under LA frameworks.
