Top job nolandyet. My council rents one of its sites and pays £620. There are approximately 300 poles let and I'd estimate the site to be around 2.8 acres in total. It's not top quality arable land, though is better than pasture. It's well over the top for arable land, though around towns you're always competing with people who want to graze horses so I really don't know what a fair market rent would be.
