Enjoy a warmer, more insulated home

Cavity wall insulation involves filling the space between the inner and outer exterior walls. You can use a variety of materials for filling the cavity space, including urea formaldehyde expanding foam, cellulose, polystyrene beads and mineral wool or rock wool. Most of our Installers prefer to use polystyrene beads as they are much more effective and provide exceptional insulation. You’ll notice a difference in the warmth of your house straight away.

Cavity wall insulation is an effective way to keep your home warm in the winter and cool in the summer, and it can also help to reduce noise pollution. Want to find out more? Get in touch.

Questions about cavity wall insulation

ECO4 will be a four-year scheme and is intended to run from 1 April 2022 to 31 March 2026. The main objective of ECO4 is to improve the least energy efficient housing occupied by low income and vulnerable households.

Under ECO, medium and larger energy suppliers fund the installation of energy efficiency measures in British households. Each obligated supplier has an overall target based on its share of the domestic energy market in Britain. The obligated energy suppliers work with installers to introduce certain efficiency measures into your homes.

The first step is to check your eligibility. Fill out our eligibility checker to see whether your home qualifies and let us take care of the rest for you!
