Founded in 1875, Leeds Building Society has launched its pilot digital savings product on Mambu’s cloud-native platform as part of its multi-year core modernisation to better serve its one million members.
Leeds Building Society

Leeds Building Society is the UK’s fifth-largest building society and operates as a mutual, meaning it is owned by its over one million members across the UK. Established in 1875, it has been helping members to save money and buy a home ever since. This is still at the heart of its purpose – to put home ownership within reach for more people, generation after generation.
Recent initiatives include stopping lending on second residential homes, launching products and services specifically for first-time buyers and advocating for housing and planning policy reform.
It has invested in its business and the same time as delivering for its members and communities, consistently paying above market average levels of interest to savers, raising millions of pounds for charities and donating thousands of hours in workforce volunteering time.
After operating on a legacy core system for over 20 years, Leeds Building Society faced significant challenges in meeting the evolving needs of its members. To stay competitive and offer more innovative services, the building society recognised the necessity of modernising its tech stack.
With an expanding membership base and a growing demand for digital solutions, Leeds Building Society needed a flexible and scalable platform that would allow them to launch new products quickly, scale services effectively and provide a seamless, quick, and effective financial experience for their members.
