Principality Building Society

We’re the largest Welsh building society – and proud of it.

Because we’re a mutual society, which means we’re owned by our members rather than shareholders, we’re in business solely for the benefit of our customers.

Today, with over 420,000 members, 51 branches, and employing over 600 staff across Wales and the Borders, we’re a significant player in the Welsh economy.
