According to the Energy Saving Trust, in an uninsulated home;

• 26% of heat is lost through the roof
• 33% is lost through the walls
• 18% is lost through the windows
• 11% is lost through the floor and the door
• 12% is lost due to draughts and essential ventilation

Heat that is lost through these ways means that energy is wasted, and money is wasted. If less heat escapes from your home you can save energy and save money.

How can you save energy and save money?

Cavity wall insulation is one of the most cost-effective energy efficiency measures you can take in the home. In an uninsulated home it could save you up to £115 each year on your energy bills.

Investing in draught excluders is also an efficient cost effective measure. Draught excluders can be fitted for doors, windows and letterboxes opening onto the outside. Draught excluders will reduce the amount of warm air escaping, saving you energy. Any gaps you find between skirting boards and floorboards are also worth fixing.

Energy efficient double-glazing cuts heat loss and also reduces noise and condensation problems. Installing energy efficient double glazing could mean savings of around £135 on bills annually if whole-house single glazing is replaced with Energy Saving Recommended double glazing.

Statistics from the Energy Saving Trust

• The amount of heat lost in homes annually through uninsulated lofts and cavity walls is enough to heat over 1.6 million homes for a year.
• If everyone in the UK that could installed cavity wall insulation, we would cut CO2 emissions by nearly 4 million tonnes. That's enough CO2 to fill over 22 million double-decker buses or fill Wembley stadium 500 times.
• If every household in the UK, that could installed cavity wall insulation, it would save around £700 million a year or enough energy to heat 900,000 homes for the same period.
• If everyone in the UK installed loft insulation up to 270mm thickness, the financial saving would pay the gas bills of around 770,000 families for a year.
• We would also save nearly 3 million tonnes of CO2 per year, the equivalent saving of taking nearly 1 million UK cars off the road.
