Hi, unfortunately the job role of a criminal profiler doesn't really exist here in the UK, it's more of a thing in the US. The closest thing we have in the UK is probably a Behavioural Investigative Advisor (BIA) working for the National Crime Agency, but considering there's only 3 of them employed in this country it's practically impossible to get into that line of work.
If you went down the Forensic Psychology or Criminology route, you could potentially work for the police which I guess is the next best thing
