I know you’ve already had an answer to this but in addition to what’s been mentioned, student support services - disability support, mental health support, pastoral support, access to support with abuse / violence etc, student complaints, computer systems to coordinate support, international student support, support for carers / care leavers / neurodivergent students, safeguarding, emergency funding for students, the cost of arranging placements, healthcare, security, catering, cleaners, accommodation, bills, furniture etc etc etc
And the cost of everything has gone up while the cost of a degree has stayed the same.
