Went to one a year old, it was one of those free for old folks schemes, installation was fine, boiler was crap, even had crossed thread on nut to diverter valve and was weeping, started to service it and then gave up, blooddy fixing screws for the front cover are crap, box full of (new) screwdrivers and nothing fits properly, cant even get to the condensate trap to clean it out, I wouldn't fit one.
