(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.

Four interesting questions he (1) is he allowed he put the pipes
etc over the border and (2) even if he made the outlets flush with the
side of his house is he allowed to discharge into your 'airspace'.
(3) are you allowed to remove the offending bits of pipe and (4) are
you allowed to block the pipes?

Sounds like uk.legal would be a good place to ask all this.
