Suggestion? - If you have SSSS on your BP then identify yourself to the gate staff even before the gate officially opens.
I had this last week from T5B and was taken through and taken downstairs immediately (Gate B32) downstairs and waited whilst swabs were taken from my luggage, hands, outside of my socks and my waist/belt area. I was then told to wait in a seat and I was to board when the first (non SSSS) passengers were coming down the escalator/stairs which was pointed out by a member of G4S when the time came. The whole process only took a few minutes and the staff were polite and professional about the whole thing.
One 'advantage' was that I had the whole of the UD for about 4-5 minutes to myself before other J passengers arrived!
