The City & Guilds College Association (CGCA) extends an invitation to all full time students, including post graduate students, of the Engineering Faculty of Imperial College to have free membership of the City & Guilds College Association while they are students at Imperial. The free membership then continues until the January after your graduation. At that time to remain a member you must become a standard member, paying the annual fee that is currently £15.

Join the City& Guilds College Association (CGCA) while at college and start your life long link with Imperial College Faculty of Engineering, its staff, current students and past students. Having a link with College, and its past students that you can call on at any time is an invaluable resource that helps your social and business life. 

Each year CGCA provides a calendar of events backed by multiple channel communications that enable you to stay in contact with your class mates and friends from College wherever your career takes you. 

The social calendar includes:

• The Annual Dinner, usually in February / March and held at a Livery Company Hall in the City of London.
• The President's Evening in May / June timeframe, a supper reception that follows on from CGCA AGM.
• The 5 & 10 year Reunion that gives an opportunity for 'old friends' to meet and share a lunch near to college.


In addition we jointly arrange events with CGCU that appeal to students and alumni alike and have included suppers and receptions. All events enable both social and business networking with people who share an interest in the history, traditions and excellence of studying at College. If you are in the London area you can also join our programme of guided tours around areas of London.

CGCA runs both printed and online communications. There are two issues of our house magazine, 'Imperial Engineer' each year which carries a mix of technology articles and social updates. We have a website that has reports of events and general information about CGCA and a LinkedIn group 'City & Guilds College Association' for more interactive interaction with other members.

Also don't overlook our sister organisation, the Old Centralians' Trust, a registered charity that provides support for students to undertake non academic projects, expeditions as well as providing financial support for those that encounter real hardship while at College.
