The Charities Aid Foundation (CAF) is a leading, century‑old UK charity that distributes over £1bn annually and provides end‑to‑end financial and advisory services—charity banking (CAF Bank), savings and investment products, secured and unsecured loans, social investment, strategic consultancy and research—to donors, companies and charities. This reference is included in 'Our Financial Vehicles in Action' because CAF exemplifies how charitable financial vehicles operate at scale: its banking, investment and social‑finance products, combined with advisory services and published research and case studies, show practical deployment of financial tools and impact evidence useful for assessing partnerships and social‑impact investment opportunities.
