About The Royal College of Science Union

The Royal College of Science Union, or RCSU for short, is the Constituent Union for the Faculty of Natural Sciences (FoNS) – if you’re a Biologist, Biochemist, Chemist, Physicist or Mathematician, you’re a member of the RCSU!

Since the founding of the Royal College of Science Union in 1881, we’ve been involved in student representation for all Science students, but that’s not all we do. We provide a wide range of services and opportunities for our members and all Imperial students.

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

  • Social events – bar nights, balls and anything in between
  • Careers Talks
  • Broadsheet – our award-winning magazine
  • Science Challenge – an annual national competition promoting science communication to Imperial and secondary school students.
  • Departmental Societies, Academic Societies and Sports Clubs
  • Academic and Welfare Representation

We’re a constantly changing organisation with new things every year – if there’s something we don’t do, you can get involved with the RCSU and make something exciting happen!

Governing Documents

Check out our Governing Documents – our Constitution, Regulations and Policies by which we run the whole organisation.

Also check out our meeting minutes and comittee page – these will give a much less dry picture of the stuff we do! – link to agendas and minutes.


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 is responsible 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.
