I am currently undergoing a extension on my house and I need to extend my Worcester Bosch Greenstar 30i boiler flue. At the minute the boiler flue has a simple horizontal extension kit on but I need to extend the flue up vertically into the floor space the approx 1900mm underfloor and out of the new external wall.
My questions are can i do this myself safely and legally and in terms of the vertical adapter and extension pieces would it be ok to buy these off the likes of EBay etc..
