I am in thr process of having a kitchen fitted, the were multiple omissions from the order abd the replacements were broken or insufficient. The fitted installed the integrated washer an a worktop offcut. managed to reverse the flow of water cold water into the header tank, left a socket hanging off the wall, made more than a dozen major installation errors. Installed the units before plastering, disconnected the outside water supply. Cut off the electricity supply in another room defrosting the fridge freezer. The installation is going into the third week with no completion. Tomorrow I will review all the problems with it and see what he has to say before raising a dispute with B&Q and commencing legal proceedings in the shortest possible time to remediate the kitchen. Grossly Incompetent.
