Your school is heating empty classrooms. We can prove it — and stop it.
Schools typically waste 20–30% of their energy out of hours — evenings, weekends and holidays. Sensors measure the waste, the platform removes it automatically, and the savings are banked towards solar, batteries and beyond.

What the meters actually show.
These figures come from half-hourly meter data and classroom sensors across measured UK schools.
Gas, unmanaged school
of annual gas burned outside occupied hours — evenings, weekends and holidays, heating nobody.
Electricity, secondary school
running at 3am, every night of the year — a baseload worth more than a primary school's whole heating bill.
Holiday classrooms
measured in empty classrooms during holidays, when 12°C protects the building. Nine degrees bought for nobody.
Nobody can see it — so nobody can stop it.
No visibility
90% of buildings have no monitoring. The bill arrives quarterly; the waste happens half-hour by half-hour.
Schedules set once
Heating programmed years ago for a timetable that no longer exists — and never reviewed.
Holidays inherit term time
Weekends and holidays run on weekday settings. Summer boilers cycle as if children were at their desks.
Broken meters go unnoticed
We found meters reading zero for two years, and a school gas meter under-reading 50-fold — confirmed in the estate's own issue log.
Measure. See. Act. Prove.
01 · Week 1
Measure
~£1,300 of sensors and a boiler controller per school. Zone temperatures, CO₂, outside air, meters.
02 · Month 1
See
The platform shows the waste signatures — out-of-hours heating, night loads, holiday burn — in pounds.
03 · Term 1
Act
Schedules align to real occupancy, automatically. Classrooms warm for arrival; comfort floors (HSE 16°C, BB101 air quality) are hard constraints.
04 · Ongoing
Prove
Savings verified against utility data (IPMVP Option C). The same sensor log is your compliance record.
Same estate. Same school type. One difference.
School without controls
of gas burned outside occupied hours
School where the sensor data was acted on
same measure, after manual optimisation
One person, reading the sensor data, re-scheduled one school’s heating — and cut out-of-hours gas to 16% with zero weekend burn. The platform automates exactly that intervention, for every school, permanently.

When it pays for itself
Cumulative central saving vs hardware cost, first 24 months.
Estimate only — central scenario of a five-lever model benchmarked on measured schools, scaled for your existing controls. 30p/kWh electricity and 7p/kWh gas for the CO₂ conversion (DEFRA-style factors). Your half-hourly meter data turns this into a measured figure.
The pathway to a school microgrid.
Banked savings become a war chest, and the war chest follows one rule: each phase buys itself. Schools have the roof for solar, the fields and car parks for ground-source heat and storage — and they’re empty exactly when solar peaks.
Phase 1 · Now
Controls
Stop the waste. Savings begin in months, verified against your bills.
Phase 2 · Years 3–7
Solar
The war chest funds rooftop PV — no new budget asked for.
Phase 3 · Years 5–10
Battery + fleet
Storage lifts self-use; summer solar charges fleet vehicles on your car park.
Phase 4 · With finance
Heat pump → microgrid
Ground loops under playing fields decarbonise heat, blended with grant funding. The school becomes community energy infrastructure.
One pilot school. One term. One evidence pack.
~£1,300 of kit, savings measured against your own bills, and a board-ready report at the end of it.
