So even with it begin less than 300mm from the party wall it won't stop the boiler falling in to gas safe requirements?Nope
The plume kit could cost about £80 and will take about 30 min to do.
A ladder is needed which also has to be loaded and transported if you don't have one.
I don't see what it would achieve apart from giving you pleasure of being bloody minded and causing your neighbour ( or the gas installer ) extra expense as well as creating friction with neighbours!
But as its incorrect you could complain to Building Control first and then perhaps to Gas Safe.
I have to say that I wonder what a Gas Safe inspector would be thinking!
