If I was your age even if in a good job I'd get out of the UK, & get out of Europe fast. Don't ask why just read the papers & read up on 20c European history.
America or Australia & if you learn a language your options will be greater, but whatever GO NOW.
Remember this advice in years to come.

Where are you based?

Defo look at engineering apprenticeships. Look for aerospace,automotive or other high end engineering. Big companies will be better with proper training rather than 4 years of being there boy, and if you perform will pay you through a degree too.
