I got a long interview there last year; that's how I know for sure
Shoreham is just the same as Farnborough on that GAR form; it should have *2 next to it.
It's designated for Customs (which means you don't have to advise Customs in advance before landing there from outside the EU) but it is not designated for Terrorism (which means you
do have to advise Special Branch before landing there from the Common Travel Area).
A lot of attention has been drawn to that mistake over the last few years but it's still there on the URL you give.
