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.

Hanging out clothes to dry will save you energy and money over using a tumble drier.

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.

Carbon monoxide is a silent killer. Every year in the UK it kills around 50 people and sends 4000 to A&E for emergency treatment. Make sure you get all your combustion appliances properly serviced and fit an alarm. Good quality alarms are available from most DIY suppliers and take minutes to fit. It could save your life!

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

Thermostatic radiator valves (TRVs) help ensure your heating is evenly distributed where you need it. Check them to make sure they are set properly so each area reaches the temperature you need and gets no hotter.

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.

When did you last test your carbon monoxide alarm? Make sure it works when you need it by testing it weekly. #TestItTuesday

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