How Were Cavity Wall Insulation’s Mis Sold?

Many property owners in the United Kingdom were persuaded by energy companies to take part in the Government’s Energy Efficiency Scheme, by installing cavity wall insulation with the promise of reduced energy bills.  This work was subcontracted to CWI installation firms by the Energy Companies that were required to meet the government’s energy target.  CWI installation companies were also given the responsibility of attracting property owners into the scheme.

However, the Government later published a report in December 2016 admitting that there were “too many poor quality CWI installations” done by companies that did not have the necessary skills. This has resulted in approximately 1.5 million homes suffering from damp and mould problems. In addition, health problems have reported by the occupants of the affected homes.

The Cavity Insulation Guarantee Agency (CIGA) is the organisation that is responsibility for putting things right for consumers if something goes wrong with the insulation work even when the insulation firm does not provide redress.

 However, both the CIGA and the Installers have declined to acknowledge that the cavity wall insulation is the cause of the problems. Instead, they have both constantly insisted that the damp and mould problems are caused by the construction faults in the building or lifestyle condensation caused by the occupants.

It is work of the work of the CWI installer to assess the suitability of insulation before installation. Thus, they should not have installed Cavity Wall Insulation in properties with construction faults. Similarly, it is wrong to claim that lifestyle condensation caused the damp and mould problem as this could have been foreseen and homeowners warned of the issue prior to installation. Thus, the CWI Installers remain liable for the losses incurred by the property owners.

Is There a Timeframe within Which I Should Make a CWI Claim?

To make a claim, your Cavity Wall Insulation must have been installed within the last 6 years. However, you can still be able to make a claim for up to 15 years if you have just recently discovered the problem.  If you are bringing a CWI claim and wish to include a personal injury claim, then you must lodge the claim within 3 years of the health issues having arisen or you becoming aware of it. 

Where personal injury claims are concerned, claims expert may advise you to bring separate claims, i.e., one for negligent CWI installation and the other for personal injury.  This is because protocols and limitation dates for both cases differ. 

What Else Can I Claim?

In addition to Poor CWI installations and Personal Injury Claims, you can also claim that CWI was missold to you on the basis that you were made to believe that the installation was being funded by a Government grant. This was the case with many homeowners who later discovered that the funding was actually via a loan that had to be paid back via their energy bills. This resulted in unexpected costs, which of course should be reclaimed based on the fact that the Cavity Wall Insulation did not even deliver the promised results.
