The Building Society Association

The Building Society Association (BSA) is a trade organization that represents and supports building societies in the UK—mutual financial institutions that mainly offer savings accounts and home loans. The BSA advocates for these societies, promotes best practices, and ensures they operate safely and fairly for members. It works closely with regulators, provides industry insights, and helps members navigate financial regulations. Essentially, the BSA helps maintain a stable, trustworthy environment for building societies to serve their communities and supporters effectively.
