Turn your thermostat down. Reducing your room temperature by 1°C could cut your heating bills by up to 10 percent. You could save around £40 per year.
Is your water too hot? Your cylinder thermostat shouldn't need to be set higher than 60°C/140°F. (But keep it above 55°C to stop legionella growing in the system).
Close your curtains at dusk to stop heat escaping through the windows.
Always turn off the lights when you leave a room.
Don't leave appliances on standby - turn them off at the plug instead, and remember not to leave appliances like phones on charge unnecessarily.
If you're not filling up the washing machine, tumble dryer or dishwasher, use the half-load or economy programme.
Only boil as much water as you need (but remember to cover the elements if you're using an electric kettle).
A dripping hot water tap wastes energy and in one week wastes enough hot water to fill half a bath, so fix leaking taps and make sure they're fully turned off!
Use energy saving light bulbs. Just one can save you £60 over the lifetime of the bulb - as they last up to 10 times longer than ordinary lightbulbs.
Shower rather than bath, it uses less energy and water.
