I have a British Parachute Association Form 108B which gives my BPA Pilot Number and BPA Membership number which says I am authorised in accordance with the BPA Ops manual as a Parachute Pilot with specific helicopter types annotated on the back.
Mine expired a few years ago so I am not sure whether rules have changed but try looking up the BPA website if they have one.
Cheers
