Usually I'm never one to complain but after my on going experience with Homeserve I felt I needed to let people know so they may think twice before using this company. 2 months ago (November 2010) my boiler developed a grating noise and then stopped working. A Homeserve engineer visited and diagnosed a faulty fan, he logged it for a replacement part and left. Two weeks later an engineer turned up with a Fan, when he came to fit the fan he noticed it didn't have a seal and wouldn't be able to fit the fan. He also noticed that the condensing bottle was damage and would need replacing. A week later another engineer arrived with another fan (no seal) and condensing bottle. This engineer however decided that a generic o ring would work and proceeded to fit the fan and condensing bottle. Everything seemed fine for a week and a half before I noticed water leaking from the boiler followed by the boiler failing to work. I contacted homeserve again who attended a week later and reported that the engineer who fitted the condensing bottle hadn't fitted a seal on it and that was causing the water to leak and had tripped out the boiler. He said he would order a new condensing bottle. This is where I am at now, four weeks after the engineer reported needing a new condensing bottle, after calling homeserve on a weekly basis and after the coldest winter on record, the Homeserve engineer visited today WITHOUT a condensing bottle ..... He reported that the reason the boiler had tripped is that water had leaked from the condensing bottle onto the PCB and would require a new PCB. I still have no heating and a boiler that needs a new PCB and condensing bottle.
