Have you got an airport pass from the airport that you fly out from?
Nope, but such passes are probably only issued by airports, not small private airfields.
When flying in the UK, as well as abroad, I always carry my passport, pilot's licence, driving licence, AOPA membership card (which has my picture on it), and my local flying school membership card (that also has my digital picture on it). Most airport security (including Norwich) are happy with the passport + pilot's licence.
It seems odd, that there are so many people who oppose National Indentity Cards in the UK, when the ID most acceptable to UK airports, banks & anyone else in authority, is a UK passport!
