I have got an old boiler admittedly but have had british gas homecare cover for years and over that time they have practically rebuilt it with spares. It has been running fine but blew a fuse this morning.
I rang them and the engineer came out and changed the fuse and then started bashing around and scraping with a screwdriver.
He then said there is a little hole in the flue and condemned it!
i have a detector in the room that has never gone off.
Do you think he could have damaged it or would it just be wear and tear?

Hi there just to put my ore in and answer a few things, scraping / poking a flue, case or any part of the metal work with a screw driver is 100% ok as a matter of fact you should thank the engineer for his work as many would not go to the extent of these extra checks , as one guy just has said its like a car mot where they are required to do this to the underside of your car.
The co detector. this may not have gone off depending on the position of the hole with out more information its hard to say, but when a flue rots its normally on the inner flue (exhaust flue) theres a 2nd outer flue this is the air intake. so the air comes in from outside down the outer flue, burns in the boiler and is sent down the inner flue to outside, if theres a hole in the inner flue it draws the already burnt exhaust gases back into the boiler and trys to re-burn air thats got a low oxygen content this causes high co /co2 readings and over a period of time (could be days or months no way to tell) this becomes dangerous causing sooting inside the boiler this then could force co /co2 into your room then the co detector would go off.
could he have damaged it? i doubt it the flue metal is 3/4mm think and hard it would take a very strong man to puncher good metal.
