Neighbouring Fences - Who's Responsible For Upkeep?
I'm in a bit of a seemingly unusual position where I live in a semi-detached house (Cheltenham, England) with one fence seperating myself from the other semi on the right, but with the back ends of a number of gardens running the length of the left hand side.
The gardens of neighbours 1-6 on the left all have their own/different fencing which means they are in differing states of repair - but all require attention. Most of the gardens have sheds at the end which means the occupants have no view or idea that the fences are either broken or in a couple of cases, gone completely as they can't see what's behind the shed.
So my question is fairly simple - who is responsible for the upkeep of these? Should I be knocking on their doors to say that their boundary fence is collapsing/falling down and who should pay for any repairs? Is there a 'rule' as such, or is it simply something to organise amongst ourselves?
BTW The fence on the right is good - we get on well with the landlord of the adjoining house and we went halves on a new fence there, but the left is a mess.
