Where the money comes from (2025)
Public funds 11% (£1.7M) · Other income 89%
Public funds: grants and contracts from government bodies as declared to the Charity Commission. Other income includes donations, legacies, trading and investments. Many organisations record funds from UN agencies and the European Union as income from charitable activities: in that case the public share is underestimated.

Payments to the organisation reported by the aid agencies of 17 countries (USAID, FCDO, BMZ, Sida and others) in their own IATI data, converted to euros at the year's average rate. They include funds passed on to local partners. Not all donors name the recipient of their payments, so figures may be incomplete; EU funds are in their own section.
