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.

Fitting a new insulating jacket to a bare hot water tank can save over £100 per year. Costing just a few pounds, the investment can pay itself off in a few months.

Spending one minute less in the shower each day will save up to £8 a year off your energy bills, per person. With a water meter this could save a further £11 off annual water and sewerage bills. If everyone in a four-person household did this it would lead to a total saving of £75 a year.

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

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!

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.
