This section gives a more detailed analysis of how your school’s electricity consumption has changed in the long term.
The following sections provide more background and analysis on your electricity consumption
Your electricity usage is high.
Your annual electricity usage is 35% higher than the best performing schools.
If you matched the usage of those schools you could save 150,000 kWh or £74,000 per year.
This chart shows how your electricity consumption varies throughout the year. Each bar represents a whole week and the split between holiday, weekend and school day open and closed consumption for that week. It highlights how electricity consumption generally increases in the winter and is lower in the summer. You can click on the chart to explore the data in more detail.
The colouring on the graph also highlights electricity usage over holidays in red. Holiday usage is normally caused by appliances and computers being left on (called 'baseload'). The school should aim to reduce this baseload (which also occurs at weekends and overnight during school days) as this will have a big impact on a school's energy costs. Sometimes this can be achieved by switching appliances off on Fridays before weekends and holidays, and sometimes by replacing older electrical appliances with more efficient new ones.
This chart can be a quick way to spot whether energy saving behaviour and lighting and equipment updates are having an impact on your electricity consumption. You need to be careful when comparing months with holidays, particularly Easter, which some years is in March and other times in April.
The following table outlines the potential benefits of reducing your electricity use to match Secondary schools with a similar number of pupils.
| Annual usage (kWh) | Annual co2 (kg/CO2) | Annual cost (£) | Estimated saving (£) | |
|---|---|---|---|---|
| Your school | 570,000 | 78,000 | £290,000 | - |
| Well managed | 470,000 | 64,000 | £240,000 | £49,000 |
| Exemplar | 420,000 | 57,000 | £210,000 | £74,000 |
This section looks at how your electricity consumption changes during the year, and compares consumption for the last 12 months with previous years where we have data.
Unless the school has had additional buildings added, if you are managing your electricity consumption well this should show a downward trend; more modern ICT equipment, LED lighting and behaviour change all contribute to reducing electricity usage.
This chart shows how your electricity consumption varies throughout the year over the long term. Each bar represents a whole week and the split between holiday, weekend and school day open and closed consumption for that week. It highlights how electricity consumption generally increases in the winter and is lower in the summer. You can click on the chart to explore the data in more detail. As above, you should see a general downward trend.
Calculations based on Electricity consumed between 01 Sep 2018 and 06 Apr 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 | 11793.0m2 |
| Location | LS10 1HW (-1.535344, 53.790991) |
| Pupils | 1269 |
| Type | Secondary |
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
