My property was severely damaged through an accident by Thames Water / Lanes Group contractors recently. The damage involved a collapsed retaining wall and major damage to the extension (cracking and subsidence). I tried to open a claim with RSA about this, and instead they said that I deceived them about past subsidence history. I was not aware of any subsidence history and only recognised a thin crack on the extension wall that I thought was due to settlement. Without even sending anyone out to actually see the damage, they concluded the investigation and voided my policy! I am now stuck with the possibility of paying more than £30,000!!!!! to repair the damages caused by someone else. Summary: Extremely long response times in urgent situation, ended up voiding my home insurance and leaving me to fend off a massive case by myself! Horrible service.
