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.

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.

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

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

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.
