Green Capital Building Society

A Member-Owned Mutual Financial Institution


Green Capital Building Society is a member-owned mutual financial institution, founded to strengthen households and communities through responsible residential lending and financial services.

Supported by a member funding base, we combine traditional mutual principles with modern governance standards—delivering stability, transparency, and long-term resilience in everything we do. 

As a member-owned mutual financial institution, Green Capital Building Society exists to advance housing finance with integrity and purpose. Our core mandate—residential lending secured on property and supported by member funding—anchors a model built on prudence and long-term value creation. Through disciplined governance and responsible expansion, we aim to foster financial confidence for members and communities alike. We are building a modern mutual institution grounded in stability, transparency, and trust. 



Our Core Activities

Residential Lending

Residential mortgage lending remains at the heart of the Society. We focus on property-secured lending supported by affordability assessment, prudent credit policy, and structured risk oversight.


Member Funding

Our funding model is anchored in member participation. By maintaining a substantial member funding base, we reinforce stability, transparency, and shared financial interest.


Financial Services & Facilities

In support of our mandate, GCBS Building Society is able to provide or facilitate broader financial services aligned with member needs and consistent with our governing framework.

 

Community & Stewardship

Beyond lending, we recognise the broader responsibility of mutual institutions to promote financial resilience and community stability. Where aligned with our mandate, we support initiatives that strengthen housing access, economic confidence, and charitable engagement.


Our objective is measured growth with enduring impact.

Green Capital Building Society operates with private-bank standards of governance while preserving the integrity of the mutual tradition. Through disciplined oversight and responsible expansion, we are building a modern, resilient housing finance institution positioned for long-term relevance.
