Cavity Wall insulation – save up to £480 every year2

Cavity Wall insulation can make a big difference to your energy bills, as well as your home’s comfort and energy efficiency. It can effectively prevent your home from losing as much as a third1 of its heat through the walls. So you can stay warmer and benefit from welcome savings.

Installing Cavity Wall insulation could save you up to £480 every year2 on heating bills, depending on the size of your property.

Quick and easy installation with minimum disruption

Cavity Wall insulation fills the gap or cavity between the two layers of brick that make up the outside walls of a property. If you’re not sure if your home has cavity walls we can check for you with a no-obligation home energy assessment.

The age of a house is a big clue, so if your home was built some time after 1920 it probably has cavity walls.

We’re happy to give your home an expert energy survey, which will help you find the best solution for your property. We can also let you know if you qualify for any funding or grants towards the cost of installing Cavity Wall insulation.

We’re one of the leading Cavity Wall insulation installers in south east of England, with over 40 years of experience. We ensure installation is as quick and trouble-free as possible, and we work to keep disruption to a minimum.
