Cavity wall insulation is the most cost effective way to warm your home. 

It's a quick, hassle-free way of insulating your home and reducing your energy bills. But is it right for you and your home?  Find answers to your questions about an excellent method to save money and generate free energy.

How much money will I save?

The insulation can dramatically improve your home’s heat retention and create a warmer, more efficient home. Up to 45% of a property’s heat can escape through cavity walls, so a significant amount of your money is going to waste. The average property will save £150 a year with cavity wall insulation, although obviously this can be variable depending on a number of factors.

What is a cavity wall?

Cavity walls are two walls with a gap in between, called the cavity. The outer wall is often made of brick while the inner wall brick or concrete. Houses built after the 1920s tend to have cavity walls, making them good candidates for cavity wall insulation.

How does it work?

Cavity wall insulation works by filling the cavity space with material that reduces heat loss by stopping the air moving around inside the cavity (air is still the actual insulator). This can substantially reduce heating costs. 


What's the process, and how long does it take?

To insulate your home, our team drill a series of small holes into the outside wall of your property. Superbeads or blown fibre are blown in between the gaps in your walls. The holes are then filled to ensure your home is water-tight. The process is quick and easy - most installs only take a few hours to complete.

How long does it last?

Cavity wall installs come with a 25-year CIGA guarantee
