CAVITY WALL

FREE cavity wall insulation

Uninsulated cavity walls lose 33% or more of the heat generated within the property. So for an uninsulated house that’s £1 of heat escaping for every £3 spent heating it. If your house was built after 1930 then your property should have cavity walls which may need insulating.

More than a third of all heat lost from an uninsulated home escapes through the walls, so it shouldn’t be a surprise to learn that installing cavity wall insulation is often one of the most cost-effective measures you can undertake to save energy and reduce your heating bill year on year.

Dependent on your property and your income you could qualify to get energy saving measures completely free or highly subsidised through Government backed incentives and grants.

If you have applied in the past with no success you may be accepted now as the qualifying criteria was changed dramatically at the beginning of 2017 and then again in 2018 to help more households pass for free funding.

Do I qualify?

As a guide, houses built before 1930 are often solid wall and would not be eligible for cavity wall insulation but can claim a range of other free insulation. Many houses built between 1982 and 2000 were built with uninsulated cavities. If your property was built after 1995 then it might have been partially insulated and you are probably eligible for a cavity top-up.

Are my walls suitable for free internal wall insulation?

You will need to make sure your wall is in suitable condition. For example, if your plaster is in poor condition, or if it will not support an adhesive, it may need to be removed.

It is important to create a nice airtight seal to prevent as much heat escaping as possible, so you might also need to consider making additional improvements to floor voids or cracks.

How much can I save?

According to the Energy Saving Trust Cavity Wall Insulation of a detached house can cost anything around £725. With ECO3 funding you can have Cavity Wall Insulation for free.

In addition, the chart below shows statistics from the Energy Saving Trust (2018) on average annual energy bills savings according to your house type.
