As you know BS, I am based at EGFE these days.
At weekends the radio is manned by the flying school and training and private flying goes on. I believe Jet A1 is available, but getting it to your (relatively) large bird might require some pre-arrangement at weekends. As you know, my current steed sips Mogas from the local garage, so the Jet A1 thing should be checked.
The airfield did rather go into hibernation over a rather extended period over "Christmas". That may be what caught you out..........
It is a shame to hear the fate of the heliport, as detailed by heli1. It was useful to helicopter operators and the city, and occasionally pivotal. It is no surprise that the 2 parties are playing hard-ball, but once you no longer provide the service, the customers have to find alternatives.
South Wales has VERY limited GA facilities. It is a great shame.
I would not have thought that the length of the lease would preclude another operator from moving in. If they have both "walked away" in effect the contract no longer exists.
