The Peter Symonds College Student Union works in conjunction with Student Services to promote student interests alongside organising events for the student body, such as diversity festivals, guest speakers, charity events, concerts and end of year balls. The SU consists of the Executive Committee (President, Vice President, Treasurer, Secretary) and other officers (Canteens and Environment, Entertainments and Charity, Communications, Equality and Diversity, Officer without Portfolio and others). The Students' Union also has a history of organising and coordinating protests and demonstrations on behalf of the student body.
