The UK Sustainable Investment and Finance Association (UKSIF) is the membership organisation for those in financial services committed to promoting a more sustainable and resilient financial system that works for the benefit of society, the environment, and us all.

UKSIF exists to bring together the UK’s sustainable finance and investment community and support members to expand, enhance and promote this key sector. UKSIF's work drives growth and new opportunities for our members as global leaders in the sustainable finance industry.

UKSIF represents a diverse range of financial services firms committed to these aims, and our 260+ members, managing over £10trn in assets under management (AUM), include investment managers, pension funds, banks, financial advisers, research providers, NGOs, among others.

UKSIF and its members have been hugely active in, and supportive of, efforts to promote the sustainable finance agenda and worked closely with policymakers and others to find new ways to overcome the barriers to the growth of sustainability and deliver progress towards decarbonisation of the economy.
