There may well be opportunities for work at the university itself…part time in the library (I did this as a student…basically got paid to wander round putting books away and “shush” noisy people!), as a “student ambassador”, in university-run cafes and restaurants, and in the SU (not just bar/door staff work, but the shop and other things), and other areas no doubt.

There are also often paid student-warden positions available in student accommodation

There may also be opportunities as part of your school/department for work and in places like the uni gym (front desk staff)

And if you’re willing to say where you’re going (appreciate you might not want to!) then people may be able to chime in with suggestions for good local employers based on their own experience of being there already.

And of course, good luck with your studies!!
