The Old Centralians' Trust is a sister organisation to CGCA. It is a registered charity and is dedicated to providing help to students for:

​

• Hardship awards, to enable those with genuine financial issues to complete their studies
• Academic related grants, for example travel costs to present at conferences
• Non Academic awards for expeditions and projects to help the community

​

In recent years awards have been made to support students presenting at conferences in the USA, to build rainwater harvesting systems in Africa, an expedition to Svalbard, and to several students who found themselves in financial hardship through no fault of their own. Reports from many expeditions and projects are published in Imperial Engineer.
