We got a new Worcester Bosch boiler installed about 6 years ago by local Gassafe (or corgi back then?) engineers. It's had various problems since and been both fixed and serviced every year by Worcester Bosch. There is currently a British Gas engineer condemning it and explaining to my DH how it has been wrongly installed and where the carbon monoxide is escaping from.
I'm horrified. We have 2 detectors that didn't go off as levels were low but how can all of those engineers missed the problem? It's almost certainly been leaking since installation since its wrongly fitted flu , not wear and tear. Arrrrgh!!!!!!
Spoke to the BG engineer and he didn't think it worth complaining since they could say we had done it our selves. What on earth is the point if Gassafe if not to take care of all this?
