lol lol I think its more a common law,
here is pretty much the reply to someone who threatens to "doorstep call" you
Should it be your intention to arrange a “doorstep call”, please be advised that under OFT rules, you can only visit me at my home if you make an appointment and I have no wish to make an appointment with you.
There is only an implied license under English Common Law for people to be able to visit me on my property without express permission; the postman and people asking for directions etc (Armstrong v. Sheppard and Short Ltd [1959] 2 Q.B. per Lord Evershed M.R.). Therefore take note that I revoke license under Common Law for you, or your representatives to visit me at my property and if you do so, then you will be liable to damages for a tort of trespass and action will be taken, including but not limited to, police attendance.
Have used that a couple of times for reasons I won't discuss...lol and no-one has door knocked yet !!!...lol except a window cleaner...lol
