British International Investment

British International Investment (BII) is the UK's development finance institution and impact investor, owned by the UK government. It deploys patient capital into emerging markets across Asia and Africa to drive sustainable, inclusive growth, with a strong emphasis on climate-aligned and clean-energy investments alongside private-sector development.

BII's mission is to create productive, sustainable and inclusive economies in developing markets. Climate finance is central — it targets net-zero-aligned investments, with a commitment to deploy significant capital into climate solutions including renewables, clean infrastructure, and resilient supply chains.

BII has a dedicated on-the-ground presence in India, one of its highest-priority markets. It operates through direct equity stakes, fund investments, and debt in Indian clean energy, financial services, and infrastructure. India represents one of BII's largest cumulative investment destinations in Asia, with active portfolio management from its regional office.
