Welcome to the website for the Royal College of Science Union (RCSU). Within these pages you can find details of what we have done, what we will do and what we are here for. If you’re a Biologist, Biochemist, Chemist, Physicist, or Mathematician you have come to the right place to find out about your Faculty Union.

Since its founding in 1881, the Royal College of Science Union (RCSU) has been involved with the welfare and representation of all members of Imperial Colleges’ Faculty of Natural Sciences. The RCSU has a great deal of traditions that are as long as the Union itself. These include singing of the traditional song, the kangela, and protecting our cherished mascot Theta. All Faculty Unions (FUs) are involved with a sport known as mascotry, where by the successful ‘theft’ of their mascot results in a forfeit for that Union. We also have a mascot that cannot be stolen by the rival FUs, a Dennis N-Type fire engine called Jezebel. Jez is maintained by the RCS Motor Club and can often be seen at large events throughout the year.

The RCSU provides a wide range of services for our members, including:

  • Events and Parties
  • Academic representation
  • Welfare provision
  • Careers talks
  • An award winning magazine
  • Academic clubs and societies

But if there is something we don’t do, you can get involved in the RCSU’s organisation and make something exciting happen.

We also organise a large-reaching Science competition known as the Science Challenge. The competition is open to both University students and 6th form students in local schools and colleges.


The RCSU consists of several officers whose main role is to help you during your studies. We are a mixture of students from across the Faculty and across the globe! We have faced a great deal of the problems you may encounter and know the right people to help you resolve them, so don’t hesitate to contact us. Members of the RCSU Executive Committee sit on Central Union Committees.

All of our committees and their minutes can be read online. See our committees page for more detailed information.


The RCSU is responsible for for all of the Science Departmental Societies at Imperial. Societies organise many events throughout the term and are there to look after the welfare and academic interests of their students. Students not studying ‘Maths’ for instance, can still be a part of ‘MathSoc’ – all Departmental Societies are open to others, it’s just that your membership is not automatic.
