Awful installation of ventilation fans has damaged property.
We recently had the fans installed by Dyson Energy Services ready for our GBIS loft insulation. The work carried out is shockingly bad and has damaged my property. - The tiles in the bathroom around the fan have been cracked. - The men have cut into an original brick arch over the kitchen window. They did not tell/ask me despite me being in the property. - The fan in the top WC has damaged the surrounding brickwork which has been left as a gap. This will allow water to enter the wall when it rains. - They have cracked ceiling tiles upstairs while installing the wiring. - There are also marks in the ceiling downstairs where damage has been covered up with sealant. - One of the men asked if I had any cement as a "brick had popped out". He had to go and buy some to cement it back in. - I have received no paperwork regarding the fans (which are awful looking by the way) As these are electric items wired into my home should I not have some information about them? Are they pac tested? Who makes them? Who do I contact if they stop working? Currently have a complaint filed with Octopus Energy who have contracted Dyson to complete this work and have asked for removal of all products and wiring. Absolutely awful.
