If you are looking at an aviation related degree I would suggest that you look at Kingston University who offer a good three year degree with aviation studies forming only part of that.
Regarding the suggestion that you go to university and join the UAS, I would point out that there is fierce competition for places an a UAS. The last time I was involved in UAS recruiting we had some 200 applications for 10 places, otherwise a very good idea.
The bottom line is that to get the licences costs a lot of money, and then you have to find a job.
Good luck
