water problem in cellar

[marsaday]

I have a terrace i rent out and it has a kitchen in the cellar. all has been well for many years - nice and dry. however the neighbours cellar is holding water (not converted) and the water is passing through the dividing wall into by house. they have had water in their cellar and if you look down the cellar light well it is just a pool of water (a bloody well in fact)

their drain is blocked it seems.

Does anyone know where i go from here legally. i know the cost of excavation will be very high to get down to the damaged pipe.

i am happy to work with the owner (he rents his out as well) but i havent spoken to him yet. i dont know if he will be willing to cooperate. if not what legal powers do i have to make him do the work. are there any.

i have spoken to environmental health and they will come out next week.

I don't think there is a lot you can do,
My neighbour recently had his external wall tanked as we both have houses with a fielld at the back and this gets waterlogged. He was having a problem with damp.
I wasn't having this problem, but I issued concerns regarding the water he was keep out may cause me a problem and I didn't want to spend £4k sorting it out. Needless to say I got no joy!
