Hi,
There is a CDC in Penshaw, Houghton le Spring - at least I think she still does it. She is not on the cambridge site email contacts etc, but the helpline have her number. Houghton isnt too far- but I have no idea what the buses are like.
I live in washington, but see a CDC in Heaton. I know there is one in Wallsend, but tricky to get to if you dont drive, I suppose. There arent any other more local (as far as I know).
Hope this helps
