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

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.

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.

Make sure your radiators are clear so they can heat the space efficiently. Curtains or furniture can easily block them.

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.

Properly used, dishwashers use less water and energy than washing dishes by hand. However, make sure you only wash full loads and don’t pre-rinse everything in the sink first unless it really needs it.
