Install cavity wall insulation
Save money on household bills by making sure that heat isn’t escaping though your walls.
Cavity wall insulation works by injecting a substance into the space between the inner and outer levels of brickwork in the external walls of your home. There are many different types of substance that can be used to do this, but they all work by combining with the captive air in the wall cavity and becoming a filling to decrease the amount of heat escaping from your home.
If your house was built after the 1920s it is likely to have cavity walls and, unless it was built in the last 20 years, it is very probable that there isn’t any insulation in these walls. This means that up to a third of the heat you pay for could be escaping your home, being wasted and costing you money.
An average grant-aided installation can cost as little as £150 and you'll find that you will save as much as a third on your heating bills as a result of the work.
Even without a grant, the insulation will generally cost less than £500 and you will be able to re-coup this cost in around 3 years.
The installation process is quick and easy as the walls are filled from the outside, keeping mess to minimum, and taking between 2 and 3 hours for an average 3-bed semi.
The insulation also has many other benefits, such as creating a more even interior temperature, helping to prevent condensation on walls and ceilings and reducing the amount of heat building up inside your home during summer hot spells. As well as keeping your home warmer in winter, it also provides a cooling effect in hotter weather.
