Thanks. I just commented on their most recent changeset to suggest that place=farm might be better than leisure=park.

They're private, but they probably still want deliveries etc., so I can see why they want a searchable POI.

It probably doesn't help them that TN14 7SF was only assigned this April. Prior to this, the UPRN for their property (10070020199) appears to have been associated with the postcode TN14 7PQ.
