How to Save Energy

If your energy bills are higher than average, or above the price cap, this might be because you are on an uncompetitive or standard variable tariff.

To help reduce your bills there are a couple of steps that you could take:

1. Rather than boiling water in a pan, use your kettle (it uses less energy) and only fill the pan enough to cover whatever you’re cooking.

2. Make sure you don’t forget the kettle that you’ve just boiled! And try to only fill the energy with as much water as you’ll actually need.

3. Take a shower rather than a bath. A family of four swapping one bath a week to a five-minute shower could save up to £20 a year.

4. Wash your clothes on an eco-wash setting at 30˚C and wait until you have a full load.

5. Line-dry your clothes rather than using a tumble dryer.

6. Make sure all your radiators have thermostats and make sure you use them, turning down by just one degree can save as much as £75 a year.

7. Use energy-saving lightbulbs and be sure to turn off lights that don’t need to be on.

8. Clean the coils around the back of your fridge as dust can make it work harder. Also, be sure not to overfill it or leave the door open.

9. When possible only use one bowl of water when washing up. If using a dishwasher, be sure to fill it completely.
