This section gives a more detailed analysis of your school’s boiler control and some things to look out for.
If you followed our recommendations to switch your heating on later for a full year you could save £2,200.
This would reduce your gas consumption by 9.2%.
This table shows the time your heating switched on during the most recent week for which we have data.
It suggests a better time for your heating to have switched on based on that day's weather on that day, along with an expected saving if you changed your heating to match the recommended time.

This is a useful graph for determining how well controlled the timing of the boiler is. A well timed boiler should only come on at about 6:00am to get the school up to temperature by 8:00am, and then turn off again about half an hour before the school closes.
If your school has underfloor heating, it may take a few hours longer to warm up, but does not need to be on 24 hours a day.
Calculations based on Gas consumed between 30 Jul 2024 and 31 Mar 2025
The following characteristics are used when analysing your school energy data. Temperature compensation uses weather data specific to your school's location.
| Characteristic | Value |
|---|---|
| Floor area | 14731.43m2 |
| Location | AL4 0XB (-0.299214, 51.755145) |
| Pupils | 1500 |

Consumption costs are calculated based on the unit prices of energy and do not take into account standing charges or other fees.
Tariffs may be based on MAT or Local Authority averages, or an Energy Sparks default, if your school has not provided their actual tariffs.
Consumption costs are estimated based on historic tariff information.
Future savings are estimates based on your school's latest tariff information.
Potential cost savings quoted in school comparisons, e.g. for comparable "well managed" and "exemplar" schools are also based on your school's current tariffs.
School comparisons are based on benchmarking your school against comparable schools based on the characteristics outlined below.
"Exemplar" schools represent the top 17.5% of Energy Sparks schools
"Well managed" schools represent the top 30% of Energy Sparks schools
