Minimum requirement to carry passengers i.e. "Friends and Family" is a Club issued Endorsement.
BGA requirements are a minimum of a Bronze Badge, 50 hours minimum P1 in gliders, Clearance from the CFI, and a Self declaration with Doctors signature stating that there is nothing in your medical history that would prevent you gaining an HGV Class 2. (If you have a JAR or NPPL Medical then this will over-ride the latter requirement)
Club CFI's may impose higher standards and you will not be permitted to fly with a passenger unless an Assistant or Full Rated Instructor is also on site.
This permits you to take friends and family members for a flight with the proviso that you are paying for the flight. To carry paying passengers requires a Basic Instructor Rating.
If you want to know more then get a copy of "Laws and Rules" for Glider Pilots. The local club will have a copy.
