Re vehicular access over a footpath, it really is confusing, having been there, done that and earned several t-shirts. There is a limit as to how many properties can be accessed by a car off a single track, seemingly irrespective of length for one thing, I believe that it's five. Distance from the highway to a property is another factor. A footpath is just that, a footpath and a landowner is not obliged to grant consent unless it's already an established right. Not to say that the RSPB wouldn't say no to a generous donation! Yes, it will all be in the legal pack but I don't believe that Mr Horrocks can take anything for granted. My feeling is that he is effectively landlocked when it comes to access on wheels.
