Cheers M@
I've looked up on him a bit and he's a bit of a petrol head who resides in Yorkshire (probably a London pad too). Has one of the most enviable classic Porche collections on the planet apparently.
So at least I know he not going to be running after me with a shotgun for kipping between his trees.
That said, he undoubtedly rents the land for agriculture which may or may not include the wood. So will still try and acquire a permission on it if I can.
Thanks again for the efforts mate!
