London Heliport advertises with Chauffeur, taxi and local private hire car services. That sounds like three times the same thing, but I've seen taxi and private hire mentioned separately elsewhere as well. What are the differences? Does private hire mean things like Uber and other unlicensed taxis, sometimes referred to as gypsy cabs?
Chauffer: may only be supplied to customers of the heliport. Taxi: licenced, can ply for trade (you can hail at the roadside) private hire: licenced for pre-booked journeys only (but you can book by phone and be picked up as soon as a car can reach you) Uber falls in the last category.
