As far as I know, having a Glider Pilot's Licence (or equivalent) entitles you to a reduction of 10 hours or so on your PPL under JAR-FCL 1. Don't quote me on the exact number.
I am not aware of any credit towards CPL.
You
can, however, include glider hours to your total hours for CV purposes - provided of course they have been logged. The CAA does indeed consider
gliders as
aeroplanes (as opposed to ultralights for instance). I know I do - even though it doesn't make much difference to the total, I would hate to leave them out; after all, gliders taught me to get my landings right first time (no going around here)!
Cheers
