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.

Check the programmer on your heating and hot water to make sure the timings match your needs. If you don’t have a seven-day programmer fitted consider getting one.

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.
