CHiL initiatives: Tackling concerns over cavity wall insulation

Around a third of heat loss is through the walls of a house and the best way to remedy this it with the installation of Cavity Wall Insulation.


Since 1996, millions of homes in the UK have had cavity wall insulation installed and have seen reductions of up to £160 per year in their heating bills. But in light of last years Bonfield Report, there are growing concerns over the legitimacy of cavity wall installations throughout the country.

Problems from the past

As outlined by the report, around three million homes in the UK have problems with their cavity wall insulation.  The reason for this? Historically, there has been little legislation or standard surrounding the installation of insulation, which in turn, has led to an array of problems including:

  • Ineffective/ wrong materials being used in insulation
  • No reduction in heating costs  or heating costs rising
  • Dampness and mould on the walls

Following on from this, there is now a huge focus on maintaining standards when improving our homes’ energy efficiency. Despite the problems in the past, some simple initial checks can vastly reduce the chances of a bad installation in your home.

How can I check that my installer is legitimate?

From the outset, you should seek an installer who is fully qualified and a member of one of the following organisations:

  • the National Insulation Association (NIA)
  • the Cavity Insulation Guarantee Agency (CIGA)
  • the British Board of Agrément (BBA)

You should check that they are signed up to a code of professional practice like the one provided by the NIA and that the installation is guaranteed for 25 years by CIGA.

The installer should check your walls are in good condition and free of damp and should generally have the work done within 3-4 hours for an average sized house.

CHiL work with a number of fully accredited and qualified installers who work on our cavity wall insulation schemes.

What should I do if I have a problem with my existing cavity wall insulation?

If you already have cavity wall insulation and have noticed some of the problems mentioned previously in this article, you should first call the company who carried out the installation.

They should discuss the problem with you and revisit your property to find out whether the original survey or installation work is causing the problem. If so, they should arrange for remedial work to fix this or remove the insulation.

If the installer isn’t willing to help you or is no longer trading, you can contact the CIGA to find out if you have a 25 year CIGA Guarantee. If you don’t have a CIGA guarantee, you may have an insurance-backed guarantee which could provide you with cover (check your installation paperwork).

Need help with funding your cavity wall insulation?

CHiL are a government backed affordable warmth initiative which runs throughout Lancashire. We obtain funding to help give local residents free and subsidised home heating and energy efficiency measures. Our cavity wall insulation measures go through extremely rigorous checks.  

Prior to installation, fully accredited surveyors will check your walls and home suitability. They will then file a report, which will go through a secondary CASS/ISCA/CAVITY check for accuracy.

Only when this is completed and approved the cavity wall insulation can then be installed. Our installers also comply with the new PAS 2030:2017 industry standard, so you can rest assured that work on your home is being done to the highest standard.

All cavity wall installs still receive a 25 year guarantee either from CIGA or an OFGEM approved Guarantee provider.
