I need some advice from anyone with knowledge of Gas-Safe and their regulations, but first, I need to tell you a rather lengthy story. I am on a British Gas Homecare plan and had a routine mtce on 15th Feb. After 10mins, the guy condemned my central heating boiler on the grounds that it was leaking fumes from the chassis, citing a broken spot-weld. Chassis no longer in stock, so boiler was immediately declared 'dangerous', disconnected on a freezing cold day and I was given two electric fan heaters to get by. Within 2 hrs, I had a quote from BG (amazingly responsive) and then later a local gas-safe registered supplier arrived for an alternative quote ...except he didn't want to give me a quote because he saw nothing wrong with my boiler except for the 'forcing of a seam' in his opinion, to which he applied a thermal sealant, then closed up with pliers before re-connecting and testing, with 'no emissions'. I then got myself not one but two CO detectors and ran the boiler for two weeks before reporting back to BG ...not a peep from either (one had a digital readout, a big fat zero) I informed BG and they agreed to come back today (16 March) to re-inspect, but with the warning that they would in all likelihood disconnect again. So, on March 14, I got a separate inspection from a 3rd gas-safe engineer. He tested thoroughly and found one small leak around the thermostat, which he fixed with what he called an approved sealant. BG have just visited, they refute that any forcing of a seam took place and were adamant that the seam deteriorated as a result of wear and tear over 20 years (...yes, don't laugh, 20yrs old Baxi Solo WM50/4RS but all 3 remarked that, but for the disputed leak, the boiler is in perfect condition) In 20mins, they managed to get a reading of 3 parts per million CO from a probe at a distance of 1cm, but they said (1) that any reading would be sufficient to say that there was a risk to life and give cause to condemn and (2) the use of any thermal sealant to effect a repair is against gas-safe regulations, no matter how effective, because it will give-up at some point in the future ...probably when the house falls down. By the way, they told me that on the first visit, the reading was 5ppm and that is the point at which they cannot exercise any discretion ...or effect a simple repair? Given the dire consequences of CO poisoning, I would not normally dispute such information and warnings , except that I now know that a cigarette smoker in the same room would generate a higher reading, that so would my gas cooker if I lit the burner and also that it is safe to work at 35ppm over an 8hr period. Add to this the fact that two independent engineers have stated that, not only is my boiler in safe working order, but that the minor repairs of the type they carried out are not only permissable by gas-safe but are plain common sense, as an alternative to a £3k outlay to replace. As it happened, common-sense prevailed today and BG simply re-evaluated my boiler as 'at-risk' instead of 'dangerous' (this means they have warned me that it will fail at some point in future, so they leave it switched-off but not disconnected, so that I can turn back on at my own-risk) ...something tells me that if they had declared it dangerous and I had just chucked them out of the house, then they would have looked pretty daft asking Transco to intervene on the basis of a 3ppm reading. Now, here's where I need assistance ...I want to contact an ombudsman or similar body to get to the bottom of the differing views between BG and 2 independent parties with 70yrs combined experience. They say that my boiler is perfectly safe and so long as I carry on having it serviced annually and take the precaution of fitting a monoxide detector*, then my boiler is good for a few years yet *n.b. NOT because of the problem I have experienced, but because it is a low cost common-sense precaution that every householder should adopt, in their opinion ...its a shame that BG don't supply foc to HomeCare customers in return for their £350+ per annum. I went to the Gase Safe website last nite and after a tortuous process, I raised a complaint under the guise of a bad installation with an opening note to explain the actual situation ...they don't have any criteria to fit a repair/maintenence dispute. Any good, qualified, informed advice would be welcome on this ...do I have grounds for complaint against BG?
