Appaling service the tech arrived after I paid £150 for just the pleasure hit the boiler with a wrench repeatedly then overpressurised the system and left saying it needed a lot of parts I phoned endlessly and was put off saying they could not contact the tech and the parts werent in we were left a week withhout hot water / heating previous to there arrival the boiler was fine just wanted a tiny occasional drip fixed ( parts £20 from anywhere) Was told it would be £400 for the re visit and parts so paid as were desperate, eventually a week later the good tech turned up but only fitted the daighram valve kit and microswitch £20) I assumed a new pump was going to be fitted now a week or so later the pump keeps failing, so have lost all that money for £20 parts repair.i requested a bill including parts fitted and cost breakdown, they said we dont do that?????
