Neighbours guttering into our soak away

[kazzab]

Does anyone have knowledge on this ?

Our extension has a drain pipe hopper that also has the neighbours guttering directed into it, this then goes into the soak away in our garden that was built many years ago before we bought the house

We wanted to change our guttering at the back and spoke to the neighbour about them redirecting theirs, they said they were under the impression that they took the front not their down pipe and we took the back

Tried looking it up but can't find anything on the internet regarding this

Have you been outside to look if they take the rainwater at the front?

Why do you need to change the gutter?

If it worries you speak to the local building control.
