Chisholme has always been dependent on the spirit of generosity. Countless selfless acts, such as time freely given, or donations small and large, have enabled the Institute to be owned by no-one and everyone. It has never been dependent on any single donor or on funding from particular interest groups. Chisholme is largely supported by course fees, covenants, legacies, one-off donations, and of course by the grace and goodwill of many, many volunteers.

Over the years, the Institute has been grateful for project grants from Historic Scotland, the Millenium Forest Project, and the Energy Saving Trust as well as ongoing support from
The Beshara Trust.
