The Student Union Executive Committee is comprised of eight students who are democratically elected by the student body each March. Any student who has good attendance, behaviour and punctuality may stand for election.

The SU manage a budget, liaise with college staff on behalf of students, represent students' views at meetings, plan events and activities, support enrichment activities, and promote Learner Voice across college. They have an office where students can drop in during lunchtimes to discuss ideas, concerns or queries. Elections for new officers take place every year during the Summer Term.
