Hi Liam!
As a previous poster mentioned, if you ever get stuck for cash for powered flying, don't push gliding to one side (or if you're craving some beautiful mountain wave flying!!
).
By the sounds of it your nearest club is Lossiemouth or Feshiebridge, but I know there is a great youth atmosphere at Portmoak (and some great folk at Aboyne). I believe some of these clubs do week long courses, and some of your gliding P1 hours will go towards your LAPL.
If you're interested, check out the UK Junior Gliding Facebook page (
https://www.facebook.com/ukjuniorgliding). We don't bite
Good luck with your flying, I'm a similar age and I know how exciting it is!!
