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

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.

Wash fruit and vegetables in a bowl, not under a running tap, to cut water use. Use the leftover water for your houseplants or patio pots.

Properly used, dishwashers use less water and energy than washing dishes by hand. However, make sure you only wash full loads and don’t pre-rinse everything in the sink first unless it really needs it.

Save energy with your washing machine. Modern washing powders often let you achieve the same results with lower temperatures.

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

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

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.
