Hi RT
Apprenticeships are the best way into this if you are lucky enough, contact the training department of all the engineering companies and airlines asking about the apprenticeships and if there is anything coming up or next year. Getting your first job is the hardest, its all about getting your foot in the door.
What Cockney Steve said is very true and his advice is wise.
90sAME mentions about other methods to enter the industry, but in reality, is very rarely these methods that get people into aviation. Getting a fitters job with or without a licence is hard without any prior experience. And paying for your own training to become licensed still leaves you with no real experience. Basically it is hard to get the initial experience.
I do not recommend spending the money on a course of this type as I see too many students with brains and money take this route and not get what they had hoped from it. (many indians do this at places like ICAT, Bristol College etc)
If you cannot find an apprenticeship, Have you consider the RAF or Navy for an apprenticeship where you will recieve good training real aircraft experience albeit not civilian aircraft. I personally did not take this route and was lucky enough to land an apprenticeship, but many of the lads I work with took this route from the forces - and have ended up well.
Best of luck.
