We purchased a valliant combi boiler from them with 3 rtv radiator valves for the bedrooms. We were told by the sales man and also a surveyor all the pipe work would be done internally inside the kitchen and would take 2 men 2 days to complete the job. only one man turned up and completed the job in a day. He's ran the gas pipe and two others on the outside of the front on the house which looks a right mess ( over 70 houses in our close most with combi boilers ,ours is the only one with all the pipes outside). When we complained to them they sent out a surveyor,who told us he had no idea why he had put the pipes outside and could see no reason why he hadn't put them internally as first agreed. They were supposed to call us back in the next couple of days,no return call,so we called them over a week later to ask what was happening, to be told that the surveyor had spoken to the fitter and he had told him it looked a bit tricky, so they both then agreed its ok to leave the pipes outside. They also never fitted the 3 radiator valves as they were never added to the order by the sales man (who suggested we had them as they were on offer),so now we've got to pay £67 on top of the original price if we want them. I'm amazed at just how bad the customer service is, the fitter has came on his own,rushed the job to get it done in a day,with no care for our property,drilling big holes through the walls to save him a bit of time and they are telling us its ok, Please avoid ,unless you like having a lot of STRESS!!
