Get yourself into the RAF into Trade Group 9 (Air Traffic Control Assistant). Then get streamed as a Ops Assistant. The pay is better then you appear to be getting (£15000 rising to £25000 after a few years if you keep your nose clean...). You also get to go to exciting places, meet interesting people, and shoot them (but only if shot at first under rules of engagement)...
You don't need a degree to do assisting in the RAF. Use your degree to get a Commission in the RAF (but, again, only 3 A levels are needed- uni seems to have been a waste time unless you found the bar) and become an Operations Officer- £30000 for doing, well, not much really.
