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.

Make sure you get your boiler properly serviced every year by a competent person. It will keep you warm, safe and make sure it is working efficiently.

Remember to turn off the tap while brushing your teeth – a running tap wastes over 6 litres per minute.

Solid brick walls can be insulated internally or externally to reduce heat loss.

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.

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.

Are your heating costs literally going through the roof? Check to ensure you have 250-270 mm of loose roll loft insulation and top up if necessary.

Every degree you turn your home thermostat down could save you around £80 to £85 a year on your heating bill.

Insulate hot water pipes along their full length. Don’t waste the energy you have used to heat your hot water.
