Free Cavity Wall Insulation Grants

What is Cavity Wall Insulation?

It may not look like it, but bricks are porous. In wet weather, they’ll gradually soak up moisture. If your home had only a single skin of bricks, this water would eventually track through to your home and cause damp. The second skin with a cavity between them helps prevent damp transferring between the two.

But that cavity presents a different problem because it allows heat to easily transfer from the warmth inside to the cold outside. Cavity wall insulation helps to prevent that, regulating indoor temperatures and reducing energy consumption.

And did you know that with the help of the available government grants for cavity wall insulation (which we can help you secure funding for), you could get the service for free.

How does Cavity Wall Insulation work?

We drill small holes in the mortar between the bricks of your walls. Then we inject (or blow) loose-fill insulation into the cavity. The whole process only takes a few hours and we seal the mortar again once we’re done.

Can we get a Government Grant for free Cavity Wall Insulation?

If you’re a UK homeowner, landlord or tenant* with an energy inefficient home, you may be able to get a wall cavity insulation grant as part of the Great British Insulation Scheme.

Depending on your household income and any benefits you receive, you may be able to access cavity wall insulation grants that could cover all or part of the cost of installing insulation. Find out whether you qualify for funding help below.

*Sorry, we can’t accept grant applications from social housing customers.

Cavity Wall Insulation maintenance

Cavity wall insulation can help to create a warmer home and lower your energy bills for many years, but only if it stays in good condition. That’s why it’s important to have your home’s cavities checked every few years to make sure everything is as it should be. Talk to us about reviewing your insulation.
