The Savings

Around a third of all the heat lost in an un-insulated home escapes through the walls. If you have cavity walls, insulating them could save you between £130 and £160 a year on your fuel bills. It will also cut CO2 emissions by around 1 tonne. These figures are provided by The Energy Saving Trust and are based on an average size property heated by gas. Greater savings can be made in larger properties or those heated by coal or electricity.

What Is Cavity Wall Insulation?

In most houses built after the 1920s, the external walls are made of two layers with a small air gap or 'cavity' between them. If your home has unfilled cavity walls, a considerable portion of your heating bills will be spent warming the air outside.

Injecting the gap between the two walls of a house with an insulating material decreases the amount of heat escaping through the walls. Cavity Wall Insulation is quick, clean and FREE or inexpensive to install. It is injected into the cavity from the outside, typically taking two or three hours. All cavity wall installations are backed by a 25 year independent guarantee from CIGA, The Cavity Insulation Guarantee Agency.
