How did we calculate these figures?
The data on this page was last updated on 15fed Hydref 2026.
Reporting of energy savings, benchmarking and potential opportunities are based on analysing half-hourly energy data for the 12 calendar months between 15fed Hydref 2025 to 14eg Hydref 2026.
Reductions in energy use are based on comparing use with the previous 12 month period (15fed Hydref 2024 - 14eg Hydref 2025).
At the time of analysis, 5 schools had data available for at least one utility.
Other analysis, e.g. progress against energy targets is based on the latest available data at the point of analysis.
Other metrics, including school enrolment, engagement metrics and ROI values are based on the latest available data and Energy Sparks prices at the point of analysis.
Cost savings achieved are based on the current energy tariff data provided to us by the group and/or individual schools. Where not available we use a default charge.
Potential cost savings are based on current tariff data for individual schools and/or the group.
Energy Sparks may not have full coverage for all meters in schools, but school data is only made available for analysis where we have significant coverage. This means our figures may underestimate actual or potential savings.
Pupil numbers and other benchmarking metrics such as floor area are based on data taken from the Department of Education database, or as supplied to us by users.
