Switch off radiators in any rooms you are not using regularly and keep internal doors shut to save energy.

Still using tungsten, halogen or fluorescent bulbs? Changing to LED lighting can save energy and money.

Fill a jug with tap water and leave it to cool in your fridge. You’ll save water by not having to run the tap for ages to get a cold drink.

Thermostatic radiator valves (TRVs) help ensure your heating is evenly distributed where you need it. Check them to make sure they are set properly so each area reaches the temperature you need and gets no hotter.

Draught excluders are a cheap way of cutting out the chill from poorly fitting doors and windows. Most are also easy to fit, a simple DIY task.

Fit a water butt to collect rainwater. Your roof collects about 85,000 litres of rain each year (around 450 butts full). That’s water you can use for your plants and to wash the car, and it’s free!

Make sure you get your boiler properly serviced every year by a competent person. It will keep you warm, safe and make sure it is working efficiently.

Boiling food on the hob? Only use the water you need to save energy.
