I have just seen that my credit card has been charged for £1048!!!!! for a valve change to my boiler. The engineer arrived at 15:15pm, apparently diagnosed the issue, and then left the premises for an hour and a half to find parts. He returned, fitted the part and departed at 7pm. Not breakdown of any charges, no bill, no invoice. Just a credit card transaction of £1048, for not even 4 hours work, to fit one valve!! Absolute disgusting rip off. Don't go anywhere near this company!!
