About Principality Building Society
Formed in 1860, we are a vibrant, indigenous Welsh company, with over 149 years experience of serving our local community. Today, with over 420,000 Members, employing over 1,000 staff and with a network of 50 branches across Wales and the borders, we're not only a significant player in the Welsh economy but also the 9th largest building society in the UK.
As Wales’ largest mutual building society, we are proud to be in business solely for the benefit of our Members. Unlike companies with shareholder interests to satisfy, we seek to optimise, rather than maximise, profit and return value to our Members through consistently attractive savings and mortgage rates.
As well as delivering outstanding value to Members, we are proud to be at the heart of the communities in which we operate, supporting local initiatives, from sport to culture. In many Welsh towns we are a key employer, friend and face on the high street and we are committed to looking after what matters most to you.
Founded by the people of Wales and serving the needs of customers across Wales, by offering a friendly and professional service and we have no intention of compromising on this legacy.
