Your dream to be an aircraft technician was started off in the wrong way, where did you get advice to take the pathway you chose? I assume you were told this by your school career advisor. You did not ask any apprentice I know as they would all tell you a much different story illustrated by the posts above.
What are they going to teach you on a 3 or 4 year Modern Apprenticeship today that you have not covered already on your 4 year college course? Where were your Part-66 modular course exam passes? Your age now puts you outside the primary UK funding range for most sponsorship (it's a painful but true fact). Unfortunately, your current position is at a distinct disadvantage to that of someone who had taken the direct route to an aircraft maintenance apprenticeship all those years ago, and they would probably be on a decent salary and a career taking off into the blue yonder.
You should think of ways of recovering your position, perhaps improving you text in these posts might go some way to help you start. Choose your words carefully in your CV and covering letter or Email, this will be your only contact with some employers. Highlighting specific areas of practical work would be another good idea. It could be that you might be considered for a mature apprentice or trainee course. If you wish to put yourself above the other applicants for an apprentice course or similar, I would advise that you do a lot of research into Part-66 EASA licensing and the full aviation legislative system, especially for the UK CAA, this is free to do but often overlooked by many students. For a start, you could demonstrate this over the telelphone or interview, it shows you are serious.
Make sure that any Email contact with employers is spell-checked twice and contains no errors. For goodness sake, drop the 'i' in your written text. I hope that you kept a CAP 741 log book (or similar) with correctly annotated signatures from your short experience, this will be very useful to you in gaining employment and getting your license in the future. Don't forget that there are helicopters in aviation as well, this could lead you to a job in a smaller company, perhaps more local to you.
You could throw all your eggs now into doing a aviation degree course, but this will not lead to a job in aircraft maintenance as a technician, and you would become one of the many seeking the elusive 'design' job idea planted into the heads of young students from an early age.
The above is something to read or ignore, I'll let you make the choice.
