How we’ll reward your great work

Our colleagues are one of our greatest assets, so our reward offering is extremely important to us. Our package includes pension, bonus and incentive schemes, life assurance cover, critical illness protection, private healthcare and the option to buy extra holiday each year.

Colleagues can also enjoy discounts on theatre, sports and family events, and access to tickets for the latest events at Principality Stadium. Perhaps our most unique reward is the £100 we’ll give you to open a savings account at your local branch. That makes you a Member, with a stake in our business and voting rights at the Annual General Meeting. 

We know that no two of our colleagues are the same, so we also offer a flexible benefits package, 'Principality Rewards', which allows colleagues to select the benefits that matter most to them. It's one of our ways of supporting our colleagues through every stage of their working life. And now there's more choice than ever before, with benefits ranging from dental insurance, to health screening to will writing and pension advice. There's even a travel account, which allows colleagues to book a holiday and pay the cost back monthly through salary deductions.
