You can't retrospectively change a license in the UK. Therefore, anything installed or, for that matter, downloaded before Oracle changed the licensing terms in April 2019 is immune to their bullying. US laws don't apply in the UK.
As regards the different departments, you, as your IT admin for your department, get a stringent mandate (been there working in a UK University as an IT admin) to report on all your Java usage and remove anything before April 2019 and switch to something else if you really must continue to use Java.
This would not just be a Java thing; we have had similar mandates about VirtualBox and OracleDB, though we never used the latter in the first place. Some of the central "corporate" databases are still using Oracle, I believe, though I understand exit roots are planned, may even have been implemented by now.
