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.

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!

Thermal or heavy blinds and curtains can help trap heat and reduce draughts. Close them at night to reduce heating bills.

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

Washing a small load of clothes? Check you washing machine’s settings to see if you can use the “half load” programme to save water and energy.

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.

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

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.

Boiling food on the hob? Only use the water you need to save energy.
