Chatham House benefits from a wide range of philanthropic, research-related and membership support. This diversity of global support is critical to the independence of the institute.

Chatham House is a registered charity in England and Wales (charity number 208223) and a non-profit organization. The institute has been granted foreign 501(c)3 equivalency status with the United States Internal Revenue Service.

To safeguard the continuing independence and objectivity of its research, events, publications and other outputs, Chatham House staff and its Council uphold the principles of integrity, independence, objectivity and accountability in accepting any funds. This approach ensures that all of our activities contribute to the institute’s mission and public benefit. 

The institute receives no subsidy from the UK government or any other source.

In 2016 the Transparify rankings, which rated the financial transparency of 200 think tanks in 47 countries, gave Chatham House four stars out of five for the quality of the public information about our sources of funding. The creation of this section of the website is one of the steps Chatham House has taken to be more accessible about information on its funding and the institute is fully committed to improving how we record and report our sources of income.
