Cavity Wall Insulation

Cavity Wall Insulation can improve the energy efficiency of your home in an affordable way, and you may even qualify for funding towards the cost of the install!

With rising energy prices there has never been a better time to insulate your home. We provide specialised Cavity Wall Insulation services throughout the UK.

If you are in receipt of certain benefits, you may be eligible for government-funded energy improvements that can drastically reduce the cost of heating your home.

Why insulate your cavity walls?

You lose roughly 35% of the heat in your property through your walls*. Installing Cavity Wall Insulation in your home can reduce this heat loss and help save you money.

Having a more energy efficient home also reduces your carbon footprint and contributes to the fight against climate change.

How can you tell if you have cavity walls?

Houses were typically constructed with cavity walls after the 1930s. Cavity walls are made up of two brick walls creating an inner and outer layer between which is a gap or a “cavity”.  From the outside, you can identify a cavity wall as the bricks will usually have an even pattern and all bricks will be laid lengthways.*

If your property bricks with an alternating pattern and was built pre-1930, it is likely your walls are solid and Cavity Wall Insulation would not be suitable. It may still be possible to insulate these walls with Solid Wall Insulation.
