we had to refuel at a large but not particularly busy airport in the "North of England", the unit was billed almost twice as much for the associated fees than we were for the 250 litres of fuel that we uplifted - which included Navigation fees, "Runway Fees", Handling fees, Landing fees and Parking fees. We've not been inclined to lift fuel from there since.
Ah.....the Achilles Heel of UK Aviation!
In my part of the Aviation world, the government and even the Operators will install AWOS type weather systems and arrange for "On-Call" fuel if there are no Self Serve facilities available. Also....we don't ban aircraft from landing if the Airport is "Closed"....as we understand the concept of Pilot Controlled Lighting and CTAF Radio calls when operating from an Airport with no Operating Control Tower.
We see On Airport Fire Service coverage as a good thing to have....but not a necessity for Air Operations such as the Police or Private flight operations.
