This company is a rip off.!!! I was asked for my bank details immediately. I was left all over Xmas with no heating and no hot water with a young child. They took £234 out of my account for what they called a diagnosis, which a child could have worked out. Have check and no one has ever heard of a diagnosis charge.Someone came for 10 minutes, and did nothing, but look,and told me what he thought it was.He said he would contact me when he could do it and with a price, which he did ,but it was extortionate, and I said no I checked my bank and they had helped themselves to £234.which I cannot retrieve. I have since had my heating fixed with a local plumber for a fraction of the price. I do not recommend this company. In me opinion, they are dishonest.!!!
