Cavity Wall insulation – the benefits

Cavity Wall insulation is designed to fill the gap or cavity between the two layers of brick that make up the external walls of a property.

The insulation material we install can prevent cavity walls from losing as much as a third1 of a home’s heat. So you can keep in the warmth, and enjoy a home that’s much more cosy. Cavity Wall insulation can also save you up to £150 every year on energy bills.

Installed quickly and easily, with minimum disruption

If you’re not sure if your home was built with cavity walls, a big clue is it was probably built some time after 1920. We’re happy to carry out an expert no-obligation home assessment if you want to find out more. We’ll help you find the best solution for your property, and tell you if you qualify for any funding or grants towards the cost of your Cavity Wall installation.

We make installing Cavity Wall insulation surprisingly quick and easy, keeping disruption to a minimum.
