hi all,had a problem previously with locking out of boiler,someone suggested dhw flow switch which i had changed by a company,here comes the best bit,at the end after doin alot of what i consider wasting time to bunk the bill up,handed me a bill for £323.00,the part was £68.i hit the roof saying that takes the p..s as i had a pcb done at just over £200 and fan fitted for rougly the same price.i contacted another plumber he said at the most you would be charged 1 hours labour, not 3 hours.phoned the company to which there was no ansewer,convenient !!! so guys what i want to know is who can i contact to sort this company out of being ripped off,is there some association or board?
