Cavity wall claims – How It Began

The idea initially was to make the home more energy efficient enabling people to cut their energy bills, this was done by the energy companies persuading members of the public to take part in the Governments’ energy efficiency scheme by installing cavity wall insulation.
Much of this building work was subcontracted out to CWI installation companies’ to carry out the cavity insulation to meet the Government mandated energy targets, in particular homes in the south east were targeted, however the north west and northern Ireland were also included.
However, due to issues such as poor installation, poor workmanship, low quality training of the workers and other issues with the CWI installers many of these cavity wall installations were poorly carried out, leaving many British homeowners with thousands of pounds worth of damages, and other issues such as rotten woodwork, blocked air vents, dry rot, mould, damp, building condensation and scare stories of large scale damage started to surface.
The Cavity Wall Guarantee Agency (CIGA) even issued free cavity wall installations to households as part of the energy efficiency scheme and issued what is known as a ‘ciga guarantee’ of 25 years for the insulation, and certain energy supplier ran campaigns began to emerge offering free cavity wall installations.
The national insulation association began to receive complaints about the quality of the building work, (also the citizens advice bureau), citing poor installation and internal wall damage and other issues (mentioned above), trading standards also received reports of poor workmanship, and these complaints slowly turned into cavity wall insulation claims where people began to receive compensation not only to cover the damages but also compensation in addition.
Consumers who were promised a way in which to cut energy costs were left with damage to their property, but also the prospect of making a cavity claim.
When it comes to installing cavity wall insulation considerable care needs to be taken, and certain types of insulation (urea formaldehyde) can also decay with time and become less effective as an insulator.
