Does your home have a cavity?

If your house was built after 1920, the external brick and internal walls are likely to have an air gap or ‘cavity’ between them. By filling this cavity with insulating material you’ll significantly reduce the heat loss from your home and lower your energy bills.

Most houses built from the 1990s onwards have cavity wall insulation to keep the heat in, but if your house is older than that it may not have any cavity wall insulation at all. If this is the case then you may be heating the outside air, instead of just heating your home.

Here’s how much money you could save…
You will be saving significant volumes of carbon dioxide too and… doing your bit for the environment!
