Our members are predominantly UK-based organisations working in international development. They are non-governmental, non-profit distributing and non-partisan.

We also offer membership to organisations that have international departments or teams, which support development and capacity building (for example the Royal Colleges and international institutions). If this is the case for your organisation, please enter your international programme expenditure on the application form.

Our associate members are organisations not directly engaged in development, but working to support others who are (for example through research or training). Organisations based outside the UK can apply to become an international associate member (terms and conditions apply).
