As Kaorimiyazono put well, you can always look at was bursaries and scholarships your universities offer. Sometimes they can offer money for studies who receive particularly high grades in certain subjects, or submit a small essay about a particular topic. Moreover, you can contact the University's financial support department who can point you in the direction of financial support packages if you're eligible.
Otherwise, the best tips are to search for cheaper accommodation, prepare a sophisticated budget, or work alongside your studies. If you're going a city-campus University such as London or where we're based in Canterbury, there will be many part-time jobs available that often look for students. Places like supermarkets, high-street stores, pubs and restaurants are always looking for staff, and as we get further out of lockdown many places and wanting to get more staff as they reopen, so it's the perfect time!
