om...
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

d) There is no garden between the wall and my path

e) The passageway is the only access from the back to the front of the
house for pushchairs, bikes etc, so is used daily

f) I don't know what type of boiler it is - if it's a
combi this would make it worse.

g) There is no fence the wall is the boundary

Once again thanks for the input, I think I'll have a word with him and
then take things further if that doesn't have any success.

When locating a fanned flued room sealed appliance, the position of the
terminal should be such as to minimize the risk of re-entry of combustion
products through openable windows, vents etc. of opposite or adjacent
properties. A plume of products of combustion may be readily observed,
especially in cold weather or if a condensing appliance is involved.
It is recommended that a fanned flue terminal should be positioned as
follows:
a) at least 2 m from an opening in a building directly opposite; and
b) so that the products of combustion are not directed to discharge across a
boundary.
In the absence of any specific instruction from the manufacturer, a suitable
guard should be provided whenever a terminal is fitted less than 2 m above
ground, above a balcony or above a flat roof to which people have access.

Flues discharging at low level near boundaries
1.51 Flues discharging at low level near boundaries should do so at
positions where the building owner will always be able to ensure safe flue
gas dispersal. A way of achieving this where owners of adjacent land could
build up to the boundary would be to adopt the suggestions in Diagrams 3.4
or 4.2, as relevant.
"""""""""""""""""""""""""""""""""""""""""""""""""" """""""""""""""""""""""""
(Diagram 3.4 shows the terminal kept 600mm or more from the boundary line
for a gas fired fanned balanced flue; 4.2 refers to oil-fired appliances.)

From a gas safety perspective you (or a subsequent owner) might build an
extension on your property up to the boundary which would then make the
termination of his boiler unsafe. I'm not sure whether his installation
would be classed as Not to Current Standards (NCS) or At Risk (AR) but as a
new installation it certainly should not have been done in this way. The
local CORGI inspector might have something to say about it.



If the discharge pipe does not terminate safely - and in this case that
likely would mean taking it to nearing ground level - then there is cause for
concern. CORGI would be very interested to hear about this. However I'm not
sure what right you have to complain to CORGI in this matter, maybe worth
a try.

A flue terminal that extends out of a plain wall 300mm does not sound
right and I don't know of any manufacturers with such a requirement except
for the 50mm (nom) plastic pipe flues which _may_ be taken that far (but
don't need to be).
