Cavity Wall Insulation Grants & How To Apply

Published by on September 24, 2018

There are many grants available for households throughout the UK to cover the cost of cavity wall insulation, but not enough has been done to promote their existence. Cavity wall insulation is an excellent way to prevent heat escaping from your home and will save you money as you require less energy to achieve the temperatures you desire.

It may seem like a magic fix that is too good to be true, but there has been extensive research on the subject that highlights the many benefits. For example, a government study found that around a third of all heat in an un-insulated home is lost through the walls.

If you’d like to learn more about the benefits of cavity wall insulation and whether or not it’s right for your home, see our dedicated page on cavity wall insulation. From this point on we’re going to assume it’s right for you and tell you how to get the cost of it covered.

Cavity wall insulation grants

There are many different schemes available, both locally and nationally, from council-led initiatives through to grants from energy providers. The easiest way to find out whether you’re eligible for any of these is to speak to us or a similar company.

Many energy providers provide free cavity wall insulation regardless of the household income and situation. Others are more specific and may look at income or whether an occupant receives a certain benefit.

The great news is that many providers do not even require you to be a customer for you to benefit from their specific scheme as their objective is to simply reduce household emissions overall.


Don’t forget to check local schemes that you may be eligible for (the easiest way is to let us check by phoning or using our contact form).

Sometimes these are much easier to apply for as they work with businesses, such as ourselves, who will handle all the entire process, from the initial assessment through to installing the cavity wall insulation.

How do I apply for a cavity wall insulation grant?

The easiest way is to simply fill out our contact form and we will assess your situation and tell you what schemes are available to you. If you’re outside of our catchment area, we have an extensive list of third-parties that are trusted and we can refer you to.

How do I find out if I already have cavity wall insulation?

Most homes built within the last 20 years or so have cavity wall insulation. If you’re not sure, check the documentation you have for your home as there may be paperwork for it. You can also speak to a company such as ourselves and we can check to see whether you do have filled cavity walls.

Am I likely to be rejected free cavity wall insulation?

The following is a list of common reasons for rejection:

  • Your home is not eligible for cavity wall insulation (e.g. you have solid walls)
  • You live in a flat and other occupants do not want cavity wall insulation
  • You have on-going damp issues
  • Your cavities are too small (an assessment will identify this)
  • Your house does not rely on a steel or timber-frame

How much can cavity wall insulation save me on your energy bill?

The Energy Saving Trust, a not-for-profit organisation, estimates that a typical semi-detached home could save £145 per year on their energy bill after cavity wall insulation has been installed. This is by no means a small amount when you could get the insulation completely free of charge.

Type of home Saving per year
Detached house (four bedrooms) £225
Semi-detached house (three bedrooms) £150
Terrace house (mid with three bedrooms) £95
