Firstly, sorry for what might end up a bit of a saga to read.
My elderly mothers next door neighbours (semi detached) have recently completed their full width single story rear extension, some concerns have arisen which I would like advice about.
The main issue is that her patio is now being flooded whenever there is a large downpour. It seems that the rain water from their main roof (double width semi) is now being discharged directly onto the new flat roof which then empty's into the gutter then from the down pipe into a new gully. As you can see from the photos the down pipe doesn't reach the gully so the rain comes under the fence and onto my Mother's patio.
Secondly, there is a electrical cable which I'm guessing feeds their garage at the bottom of the garden which was originally on their side of the boundary but is now exiting their new side wall and down into my mothers patio.
We have attempted to explain our concerns to the neighbours but they seem to have little interest.
I therefore asked advice from the local building inspector who said the job has now been signed off and after seeing the photos simply stated that when he was last their "it wasn't like that" but would ask them to put it right. I can't see how something as basic as the down pipe not connecting with the gully could have been signed off?
Since then the neighbours have simply placed another section of wood under the fence to attempt to close the gaps.
Lastly and for info, no party wall agreement was ever sought and my mothers fence between their two property's has never been properly repaired/replaced. My mother would like to stay on reasonable terms with the neighbours but I don't want her to be taken advantage of.
Advice please?
