Shambolic! New boiler installation booked with definite dates - spent two days holiday off work and no engineers and no joy with phone calls - eventually started three days later causing real stress as had to return to work. My home was treated appallingly, and with little to no respect. Oil type black marks everywhere and bannisters are going to need redecorating as now permeated the paintwork. BG engineers left dirt and incorrectly fitted pipework causing overheating. Had to get local engineer as BG would not sent anyone back for five days. Electrics wrong place, mucky carpets which I had to shampoo. Taken three months for them to totally complete job which should have been finished by 30th October. Claims department very insulting and totally ignorant (wilfully, I would say), in an effort to avoid paying any sensible damages etc. One of the most expensive experiences of my life. They just don't get it! Never recommend them. I could write a very good article in the national press on my experiences here!
