In reply to littleknees:
Your going to struggle, the land is mainly either good agricultural land or managed shooting land. I would suggest if your very very discreet and camp late an leave early, you may be successful, but remember that you have no legal rights to do this and can be asked to leave immediately, maybe even some legal action for trespass, though how real that threat is I`m not sure.
If you want to wild camp head for the Lakes where it is tolerated, or if in the Dales use a campsite or ask a farmers permission, you may be surprised most farmers in my experience are pretty cool dudes.
