So, who are Principality?

  • Years of experience, building for the future.

    We're shaping a better future for our members with fresh ideas plus 165 years' of knowledge.

  • Made in Wales, here for everyone.

    We're the 6th largest building society in the UK. That means Welsh roots with national clout. (We think that's the perfect blend). Here for you online and in person.

  • Guided and owned by you.

    We're in this together, so you get a say in how we do things. Being a mutual means we're run for our 500,000+ members.

Curious about the finer details? Visit our corporate governance pages and read our Society Rules.

We follow Consumer Duty rules to make sure we’re doing all we can to deliver fair value and good outcomes to support our members.


We're regulated by the PRA and FCA, which means we're legally required to follow these rules to put your interests first, keep your money secure and make sure things are fair.


But we don't follow these rules just because they're a requirement, we follow them simply because it's the right thing to do. Looking after our members is a choice we're proud to make.

Your peace of mind is our priority. We're governed by an experienced Board that makes sure we're operating safely, following every regulation, and protecting our members. Plus, your savings are protected by the FSCS up to £120,000 so you can rest easy knowing your future is in safe hands.

As a building society, we keep some of our profit aside to stay financially strong for the future. The rest goes straight back into doing what matters: improving our products and services, offering competitive mortgage and savings rates, and supporting the communities we’re part of. That includes our charity partnerships and initiatives like the Future Generations Fund, which helps create better opportunities for young people.


Our impact (on the pitch and beyond)

We invest in making a lasting impact on communities. That means forging partnerships that go beyond the moment and leave a legacy.

Whether that's our headline sponsorship of the iconic Principality stadium. Or local partnerships, charity initiatives, or supporting grassroots rugby.

We're committed to having a positive impact on the communities that matter to our members.
