I'm in Council Housing and I've not heard anything about this. From I've been told by my housing officer, Nottinghamshire Council Homes is a Housing Association and it is them that are forcing this rule. Stanton Hill should be Ashfield District Council, Midnightmist, (my Mum) is Newark and Sherwood District Council and I'm Mansfield District so it shouldn't affect any of us anyway even if it was a council rule.
Hopefully we can arrange a playdate, Gypsy and Ellie love playing!
