(Apologies if this double posts - tried once and google crashed)!

I have just got back from a long weekend away to find that my
neighbour has installed a cooker hood flue (at eye level) and a boiler
flue (at first floor level) through the external wall of his house
that bounds my property.


Phone and ask your local building control officer why he approved it. He
will of course be right round as I expect he hasn't heard about it.
