Boiler stopped working Saturday morning 14th Jan 23 - stayed in lock out no matter how much I tried to fire the burner. Called Homecare. Engineer booked to come out by 11am the same morning! 5 stars for that. Waited and waited and was updated by sms to say delayed and now likely after 6pm. 7pm he turned up. 4 stars now but still great service. He was also to do its annual service (after 15 months). About 5 minutes later he came out of the boiler room to declare that the heat exchanger was leaking and causing the sensors to trip out. He would try and fix it on a temporary basis but basically needed a new boiler (15 years old) About 15 mins later he re-emerged to say that the water was running down the electrical connections and it couldn't be made to work. He explained the boiler is obsolete and there are no parts available so he would report in to his dept on Monday to get a quote out for a new boiler. On the form left under 'parts ordered today' he had written main heat ex (obsolete) I have read of others complaining that BG were basically telling customers their boilers were obsolete and so I thought I would look up the specific part declared as obsolete. Guess what? 20 minutes research online found a supplier of spare parts and using the supplied parts manual identified the precise model replacement heat exchanger. It's around £360. Under my Homecover BG are supposed to repair my boiler at THEIR cost. Easy to say the boiler is obsolete and avoid doing so. It is going to get interesting as I have ordered the part
