Your gas usage over the last year of 360,000 kWh is too high. Other schools of a similar floor area use 280,000 kWh.

The Problem
Your gas usage over the last year of 360,000 kWh is too high. Other schools of a similar floor area use 280,000 kWh. If you matched the gas use of these schools you could save £2,300 per year, and if you matched the best performing schools you could save £3,000.

Common causes
  • The heating is left running during the school holidays and weekends. Weekend and holiday use should be close to zero, with only a small amount of gas used to prevent the water pipes from freezing in really cold weather. 
  • Your thermostats are turned up too high.  A 1C decrease in temperature on the thermostat leads to about a 10% decrease in gas consumption.
  • Your heating comes on too early in the morning. It is normally adequate for your heating to come on between 5.30 to 6.30am. 
  • The main boiler thermostat is situated in a cold, poorly insulated space, typically a corridor or a hall which in cold weather never gets up to temperature. This means the school heating system keeps running, even when the classrooms are too hot. 
  • Your school regularly has doors and windows open with the heating running. 
  • Your hot water system is left running all year round. 

What you should do
  • Turn off your heating and hot water during the school holidays.
  • Turn down the thermostat by 1C or more. 
  • Set the boiler to come on later in the morning.
  • Move the main boiler thermostat to a less draughty location, such as the school office.
  • Run a campaign to make sure everyone in the school knows that windows and doors should be closed when the heating is on.
