How do you actually get a IT support job without any experience at all? Traineeships? Internships? Training in general seems non exsistent in the UK

You get the job by asking for it. Apply to places that offer the apprenticeships, but make it clear that you're a university graduate and want to just get into the job rather than be on the apprenticeships scheme.

Nobody is fully qualified when they start a job. Every company lets you learn on the job when you first start. Most places will probably only be looking for cheap apprentices and turn you away, but if you don't ask you don't get what you want.

I know people who have applied to jobs this way, and got a response along the lines of "we can't give you the job you want, but how about this one" and have got a pretty decent deal out of it.
