The Building Societies Association or BSA was established in 1869. It is the voice for all 42 UK building societies, including both mutual-owned banks, as well as 7 of the largest credit unions that make up the National Credit Union Forum (NCUF). Together these organisations serve around 26 million customers in the UK.

The BSA’s objective is to champion and support its Members: To push for the best outcomes from new and changing regulation and legislation to ensure that building societies and credit unions thrive as an essential part of a diverse financial services sector – serving their savers, borrowers and communities.
