Our history

Important dates in our history

Our history can be traced back over 150 years, to our original foundations as a building society. It was set up to ensure that everyone could own their own property, while ensuring truly personal customer service and looking after our communities.

While we’ve grown and changed as a business, we’re incredibly proud of our heritage and the loyalty of our customers.
