my local authority has a section on HIGH HEDGES.. and a complaint procedure...
"From 1 June 2005, you will be able to submit formal
complaints about high hedges to the Council. These can
only be submitted where there have already been
reasonable and recent attempts to resolve this amicably
with the landowner.
The hedge in question must be evergreen, over two
metres high, and not have significant gaps. A complaint
can only be considered where there is an unreasonable
impact upon the amenity of occupiers of a residential
property and must not be a frivolous or vexatious
complaint.
Where the Council decides that the complaint is valid, it
must decide whether there is an unacceptable impact on
the complainant�s amenity. It has powers to require the
hedge to be reduced in height, although cannot require it
to be reduced lower than two metres and cannot require
its complete removal. The Council can also ensure that
the hedge is kept at this height in the future.
The Council has decided that the fee for processing such
a complaint is �400, reduced to �50 for those on income
support. "
