Cavity Wall and Loft Insulation

A well-insulated home means lower annual energy bills. That’s good for the environment, but it’s even better for your wallet.

We Can Help You Save Money

At Future Isle of Wight, we’re strong believers that helping the environment shouldn’t cost you the earth.

In fact, we think that if we improve the quality of life for Island residents by making sure that their homes are heated and insulated correctly, a big part of the environmental stuff will take care of itself.

So how do we plan on doing that?

We’re Insulation Survey Specialists. You can book a free survey of your home and we’ll identify what extra insulation measures you might benefit from, and then help you to apply for a grant with the Energy Company Obligation (ECO), a government scheme that aims to reduce carbon emissions and tackle fuel poverty.

And the best part?

If you qualify for a government grant, you could reduce the costs of installing extra insulation, or even have it done completely free!

That means you’ll instantly start saving money on your fuel bills, without having to wait years to recoup the installation costs.

The two main types of insulation that are covered by the scheme are for lofts and cavity walls:

Loft Insulation

This type of insulation is laid out in rolls on your loft floor, helping to stop the heat from your central heating escaping through the roof.

Modern loft insulation is 270mm deep. That’s just under a foot in thickness, so even if your home already has insulation installed, you might benefit from a top-up, especially if it’s over 15 years old.

If you’re eligible for a Loft Insulation Grant, it can also cover the cost of insulating and draught-proofing your loft hatch, lagging any pipework and even fitting a walk-board to access your water tank.

Cavity Wall Insulation

Cavity walls are made of two layers of bricks, with a gap of 50mm (2 inches) between each layer.

The air gap in older cavity walls was used to stop damp, but it isn’t very good at providing insulation.

It wasn’t until the early 1980s that cavity wall insulation became mandatory, so if you live in a house that was built between 1924 and 1982, you might not have any at all.

If you’re eligible, the entire cost of cavity wall insulation could be paid by a government grant. You’ll also get a 25-year guarantee from the Certified Insulation Guarantee Agency (CIGA).

Is Insulation Worthwhile?

On average, 25% of a home’s heat is lost through the roof and a staggering 35% through the walls. Upgrading your insulation can prevent some of these losses, leading to fantastic savings:


Yearly Saving

On your heating bill when you add insulation to your cavity walls.


Yearly Saving

On your heating bill when you add new insulation to your loft space.


Yearly Reduction

In carbon dioxide emissions from a home with cavity wall insulation.

Do You Qualify for a Government Grant?

To qualify for a grant, you must own the property and have bills and benefits registered at that address.

Landlords and private tenants no longer qualify, but could still get help through the Green Deal. This is a type of loan that uses energy bill savings to pay off the amount borrowed.

Please note that unfortunately, we cannot assist Council or Housing Association tenants.
