1 If your thermostat is set over 20ºC, turn it down. Lowering your thermostat by 1ºC will knock 10pc off your heating bill.
2 Lots of heat is lost through windows, so keep your curtains closed at night, even in empty rooms. And make sure curtains don't hang over radiators or all that heat will go out the window.
3 Turn off lights and heat in empty rooms. Close doors to separate heated from unheated areas.
4 Don't leave appliances on standby. Switch them off altogether and save up to 20pc of the energy they use.
5 Make better use of the timers on immersions or boilers. If everything's on timers, you're not going to forget to switch things off.
