This table summarises recent use based on the latest available data for each school.
"Last week" reports on the latest full week of data. Change in use is measured against the previous week.
"Last month" reports on the last full calendar month of data. Change in use is measured against the same month last year.
"Last year" reports on the last 12 months of data (365 days) for the school. Change in use is measured against previous 12 months period. This is a rolling 12 month period rather than calendar or academic years.
A dash ("-") indicates that we do not have enough recent data to report on that period.
"n/a" indicates that we don't have enough historical data in order to do a comparison.
Our analysis takes into account a range of characteristics for each school, including its floor area, location, pupil numbers and type.
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.
Comparisons are based on benchmarking a school against a comparable school based on the characteristics outlined above.
"Exemplar" schools represent the top 17.5% of Energy Sparks schools
"Well managed" schools represent the top 30% of Energy Sparks schools
Potential savings are based on a school reducing its usage to match those of an Exemplar school with similar characteristics.
