Don't have a site, sorry, but if you go to Camp Site Search, click on the area your interested in, and select unit type and the facilities you need etc, you should find plenty of sites listed, most with reviews by other UKCS members.
Don't forget to leave a review of the campsites you have visited this year or last!
Do you mean you are visting the UK Laurie? What part of the UK do you want to visit & what camping equipment do you intend to use, or do you want to rent a mobile home? If you want help you need to give us a few more details.
I don't whether you would find an owner willing to rent or lease you a whole working campsite, you would probably need to buy one. If you google 'campsites for sale UK' there are plenty for sale, so maybe contact some of those & make the owners a proposition. Do you mean you want to operate a campsite as a profit making business?

Do you want to rent a whole park and run it as a business?
Or are you looking to put your caravan on an existing park so just want to lease a single pitch for your caravan?
It is possible to rent or lease some types of business. Pubs and hotels being the obvious examples. I have never heard of a campsite being leased though.
You could try some for sale due to retirement and enquire if the owners would be willing to lease.
