Thanks for all the advice, to try and answer some of the questions in
the above posts:

a) There is no shared access

b) The neighbours wall forms the boundary to my property

c) The flues/pipes etc protrude directly from the wall, hence are on
my property

If this is the case, I belive you'd be completely within your rights
to simply cut them off, and cap the ends.
