Thermostatic radiator valves (TRVs) only limit the maximum temperature areas reach. It is a common misconception that they change how quickly an area heats up. Don’t turn them up thinking the room will heat up quicker.

Smart controls can help ensure your home is comfortable and energy efficient.

Using lids on your pans when cooking will save energy and help heat the contents quicker.

About a quarter of all our clean, drinkable water at home is flushed down the toilet. Place a sealed bottle of water or brick in your cistern to reduce this amount.

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.

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.
