Use a microwave. Generally a microwave oven is the most efficient way to heat up and cook food.

Spending one minute less in the shower each day will save up to £8 a year off your energy bills, per person. With a water meter this could save a further £11 off annual water and sewerage bills. If everyone in a four-person household did this it would lead to a total saving of £75 a year.

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.

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

Keeping the oven door closed while you are cooking helps keep your oven at a stable temperature. It can also improve your cooking whilst saving you energy.

Make sure your pans fully cover the rings on your hob to use all of the heat being provided. Use the right sized ring for the pan you are heating.

Switch off radiators in any rooms you are not using regularly and keep internal doors shut to save energy.

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.

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!

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.
