Please note that JAR66 doesn't cover you for aircraft below 5700Kgs (you mentioned working on light aircraft)
If you're under 24 then it might be worth checking out the BA "Professional Engineers Programme". From what I've heard they'll running it again this year after taking a break last year cos of "Financial Difficulties". The course gives you the practical training for JAR66 B1 or B2 as well as the Required 2400 Hrs needed to complete the licence.
The School in Perth is "Air Service Training (AST)" Address for them and other approved schools in on the CAA website.
Hope this helps
