Well, i rang TW. They said they weren't responsible as it wasn't shared. I explained it was effectively shared from roof level as the guttering drains to my house.
They then said they weren't responsible for dealing with rainwater so i asked why im paying for it in my bills if eyre not treating my rainwater and they agreed they might be responsible but will only come out when i have a problem. And its sunny and dry so will just have to ring them next time it pours i guess.
I think i'll still try and get a drain rod in there if i can though.
As for the plinth mentioned just above ground level - whats the best way to remove it?
Thank you all for your help so far!
