Adopting the following measures can significantly reduce your energy bills, whilst also reducing your carbon dioxide emissions.

Cavity wall insulation

Around a third of all the heat lost in an un-insulated home is lost through the walls. Cavity wall insulation is a fantastic way to significantly reduce the amount of energy you need to heat your home and could save you around £110 a year on your fuel bills.

Floor insulation

Insulating beneath floorboards will reduce heating bills and improve the comfort of your home. You could save around £50 a year by insulating your floors. Gaps and cracks around floors and skirting boards are easy to fill yourself using a tube of sealant - reducing heating bills by around a further £20 a year.

Loft Insulation

Insulating your loft could save you around £145 per year on your energy bills if you don't have any insulation there at the moment. If everyone in the UK topped up their loft insulation to 270mm, around £520m would be saved each year!

Draught proofing

Using strips and excluders to draught proof around leaky door and window frames can save around £25 a year on heating bills. If everyone in the UK draught proofed around doors and windows, we'd save nearly £200m per year!

Tanks and pipe insulation

Both tank and pipe insulation keep your water hotter for longer by reducing the amount of heat that escapes. If everyone in the UK fitted a hot water cylinder jacket that was at least 75mm thick, there would be enough carbon dioxide saved per year to fill 7 million double decker buses!

Glazing

Double glazing cuts heat lost through windows by half and installing Energy Saving Trust Recommended double glazing could save around £130 a year on your heating bills. Double glazing works by trapping air between two panes of glass creating an insulating barrier that reduces heat loss, noise and condensation.
