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.

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.

Cavity wall insulation can help prevent heat loss through your walls. Consider getting this retro-fitted if you still have uninsulated walls.

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.

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.
