What is exactly you want to do, become a licensed engineer.....B1, B2?
What did you study at the time you were in uni? Anything maths, science, engineering related would be an advantage if you decide to start studying for a license. Most license exams are about a-level standard.
Look around, there's a number of colleges around the country now that do the EASA Part 66 courses. Most apprenticeships and college courses start in September though......are you prepared to wait that long before beginning a course?
If you're after work experience keep emailing around. I've found that it's the smaller airlines that are more likely to give you the experience as they have more time to 'look after' you and teach you.
