Did you know that around 35% of all heat lost in an un-insulated home or business is lost through the walls and 25% through the roof? Insulating your roof and cavity walls reduces heat loss and your fuel bills.

Cavity wall insulation - what's it all about?

If your home was built from 1920 onwards, the chances are that its external walls are made of two layers with a small gap or `cavity' between them. This means they are `cavity walls'.

Insulating your cavity walls means filling that gap - with very good reason.

Why insulate your cavity walls?

Cavity wall insulation is an effective way to save energy and money at home. A well insulated house keeps warmth exactly where you need it - indoors.

So, insulating your cavity walls will help you to heat your home more efficiently. Using less energy reduces carbon dioxide emissions (CO₂): one of the biggest causes of climate change. You will also save money on your bills too.

Cavity wall insulation can also help to reduce condensation inside the house if it is a problem on external walls.
