Yep. On the 6th I requested a different engineer because the first one clearly had no idea what he was doing. He kept saying it was a complicated boiler and fitted lots of different bits, none of which were the problem, only the new thermostat he had fitted on the first visit. Also on his first visit he had tested the gas pressure, said it was way too high (preset) and turned it down to half and messed with the inside of the flue, both of which the engineer who made the 6th visit corrected.
I've got all the worksheets and exactly what they did.
Like I said if I had had to pay for the callouts and parts I would not be happy.
unfortunately most bg engineers are useless, on your 6th visit you must have got the senior engineer by pot luck. I would recommend you insist on getting the good one back in future and don't take no for an answer.
