One of the core purposes of the Students' Union is to represent students - both individually and collectively. In order to do this, the Union has a network of Student Representatives that are elected or appointed to various portfolios throughout the College. In addition to this, the Union runs an Advice Centre, runs various awareness campaigns, undertakes policy research and surveys and sits on a number of College committees and other external groups.
Under the constitution, the Council is the supreme body that is "the voice of students" and it is the Council's duty to govern the representative work of the Students' Union. The decisions of the Council are implemented under the superintendance of the Executive Committee.
