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.

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

If your charger has an LED to show it’s in use, it is still using energy until you switch it off at the wall or unplug 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.

Fitting a new insulating jacket to a bare hot water tank can save over £100 per year. Costing just a few pounds, the investment can pay itself off in a few months.

Use the sun to reduce your heating bills. Leave internal doors open to rooms which trap the sun so the heat can spread to other areas.

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

Only fill your kettle with the water you need. You will save both water and energy.

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.

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!
