I won't even bother with commercial side of things just now.
Combined Cadet Force or Air Cadets is also a good start.
They still do flying scholarships (when your 17 i think) which you get approximatly 12hours flying or 13 if you take the boss for a check ride
Air League These guys seem to struggle to give money away to young pilots. I personally have trained 2 who have gone from zero to IMC without paying anything but accomadation and food for 6 weeks. The lady at Air league was saying they are even having people being awarded scholarships but not being bothered taking them which seems a bit wierd to me.
