Primary school BMS upgrade £30k to £50k flat; secondary £55k to £95k. Full replacement (where the panel is end-of-life) adds 30 to 40 per cent.

The DfE Mandatory Year-End Energy return requires sub-metered consumption by fuel and ideally by zone. Most BMS upgrades need 6 to 12 additional metering points; budget £800 per point installed.
Where the existing BMS cannot accept ASHP weather compensation or cannot publish data to a Sustainability Energy Management System, the upgrade is triggered. PSDS Phase 4 effectively requires BMS data publication.
Modern BMS handles ASHP weather compensation, hot-water buffer scheduling, and (where applicable) Demand Side Response signalling for capacity market revenue. The control logic is as material to the actual SCOP as the heat-pump selection itself.
