Get into the habit of turning lights off when you leave a room. A family could save between £50 and £90 a year just by remembering to flick a switch, if they don’t already do this.

A dripping tap can waste at least 5,500 litres of water a year. If this is hot water you’re also wasting the energy used to heat it. Get leaking taps fixed promptly.

Use a microwave. Generally a microwave oven is the most efficient way to heat up and cook food.

Only fill your kettle with the water you need. You will save both water and energy.

If your charger has an LED to show it’s in use, it is still using energy until you switch it off at the wall or unplug it.

Some vulnerable people need to keep their homes warmer than normal. However, most of us can save money and energy by dressing for the weather and putting on a jumper before turning up the heating.

Hanging out clothes to dry will save you energy and money over using a tumble drier.

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

Wash fruit and vegetables in a bowl, not under a running tap, to cut water use. Use the leftover water for your houseplants or patio pots.

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!
