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!

Get into the habit of turning lights off when you leave a room. A family could save between £50 and £90 a year just by remembering to flick a switch, if they don’t already do this.

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

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

Think before your print. Reducing the amount of material you print has a long list of benefits including saving paper, chemicals and electricity. More and more offices and industries are going paper free, so think about how you can reduce any printing you do.

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

Fit a water butt to collect rainwater. Your roof collects about 85,000 litres of rain each year (around 450 butts full). That’s water you can use for your plants and to wash the car, and it’s free!

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

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

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