Royalty in the UK would presumably mean just the members of the royal family, which has a fuzzy boundary. The aristocracy is a much larger group, obviously.
Yeah, that's why I brought it up. For some 'royalty' might mean any sort of nobility while I took the original poster's meaning as the House of Windsor. I would expect that much of the land in England is held by various members of the wider aristocracy.
I make the distinction because as an American, many of my fellows conflate the two.
