The councillor came to see the house! Half an hour after I phoned her!
But... said, first, she would see the woman I have been in touch with at the Health and Housing...see if more could be done.
Said, second, that she would get in touch with the Water people to see if the leak can be stopped. (Only my problem in that it makes the ivy grow more!)
Said, third, that not much money is available these days for dealing with things lke this, and fourthly, that the ivy on the house is a civil problem....there was a charity that might help with repairs.
I don't know if that got me much further - haven't heard back yet.
I have put in a note to next door to say I am arranging for the ivy on my gutter to be removed.
Means, my gardener will go in with a ladder! - but it didn't happen yesterday because of the rain.
