Any uk uni student benefits that are not well-known/not listed on uni websites?

Hi I am an international student looking to apply to UK universities next semester for a major in English Literature! To prepare for that I’d like to know about some student benefits that are not known since everywhere I look it seems that all I can find are the usual student discounts, free library access, diverse campus population, etc.

For reference the universities I plan on applying to are:

- KCL
- UCL
- University of Edinburgh
- University of Warwick
- Durham University

Please let me know since this would help alot for interview processes, college decisions, etc. !
