You are correct. No Estate Rentcharge in title or as a separate agreement just unenforceable positive covenants.
I agree I am right and have been for 10 years my question is what action can I take to stop them billing me on an illegal basis - i.e. If I sent you an invoice without a contract and made threats what action would you threaten me with to get me to stop ?

Excellent , that's what I wanted. I run a software company and never wanted to spend a day of life researching law but over the last 10 years I feel like I am becoming a deeds expert - of course not but I know enough. Thanks for your help. I expect they'll do nothing as usual but if needed your reply will help greatly.
