Principality Building Society was first established in 1860 to provide funding for building new homes in Cardiff. Since then, we’ve continued our proud history of helping people prosper in their homes. We believe that home matters and it is the heart of life, where plans, decisions, and memories are made. We exist to help our Members to lead a fulfilling life wherever or whatever they call home at every stage of their life. Our purpose hasn’t changed in 160 years.
