What to do if my property isn’t registered with CIGA?

CIGA is the main certification body for cavity wall insulation. In most cases, you will be directed to them for a copy of a CIGA guarantee if you don’t have one. This is a vital document in processing a claim for failed cavity wall insulation. However, every now and again CIGA may not have a record of your property being registered with them. So, what should you do if this is the case?

There are a few reasons for this, one of which is your property may have simply been registered with another guarantee agency. Of the 12 million homes estimated to have had cavity wall insulation installed, about 6 million were certificated by CIGA. So, it is very possible another certification body certified your home. There is a total of 11 certification bodies approved by Ofgem with a slight variation in the kind of cavity wall insulation they certify. Below is a link to the agencies, what kind of CWI they specialise in and their contact information:


It is also possible the installer of your Cavity Wall Insulation simply did not register your property with a guarantee body at all. This was usually because funding for the Cavity Wall Insulation would run out and it cost the installer to register the property, so they simply didn’t do it.

In this case the best thing to do would be to find out if neighbours and other properties in close proximity to yours had Cavity Wall Insulation installed at a similar time and see if they have a guarantee certificate or are registered.

If this is the case, you can write to said certification body and ask them to issue a guarantee for your home in line as this was promised by the installer at time of install who would have been registered with the guarantee agency.

TCF – Treat Customers Fairly

If you were promised a suitable install and a guarantee, and they provided your neighbours with one but not you, they have a moral obligation to issue a certificate back dated to the date of install.
