No can't use the other neighbours as to far away.
We can't have a soak away as the garden isn't long enough now.
The only way to access the drain system is to dig up their patio as other neighbour has a conservatory.
Don't think they would like that.
Hi
We have had a single storey extension built and the guttering from that connects to our neighbours downpipe which then goes in a underground system.
We live in terrace house and have never had a downpipe on our side, our original guttering connects to our other neighbours downpipe.
Is it OK...
