Principality Building Society has announced that Julie-Ann Haines will be stepping down from her position as CEO.

The board has appointed Iain Mansfield as the Society's new chief executive. He will serve as CEO designate from the 13th of October, with a date in November to be agreed on the formal transition. 

Iain is Principality's current chief financial officer. He joined the Society in 2015 and has held a series of senior executive positions, including chief operating officer and managing director of its second charge loans subsidiary, Nemo. A member of the Society’s board since 2019 and a chartered accountant, Iain's broad remit has included strategy, finance, commercial lending, legal, procurement, change, IT and operations. He has experience across retail banking, start-ups and private equity-backed consumer financial services business across the UK. 

Julie-Ann has been with Principality for 18 years, holding various senior positions within the Society’s executive committee, appointed to the board in 2016, before becoming CEO in 2020. 

Simon Moore, chair of the board, said: “On behalf of the board, I would like to thank Julie-Ann for her contribution to Principality. Under her leadership, the Society has delivered consistently strong results with significant growth. Julie-Ann has championed mutuality by putting our members at the heart of decision making, through our commitment to the high street, investing in our savings product and digital proposition and in our market leading customer service. We are grateful for her efforts, and wish her every success in her new role which she will commence in the middle of 2026.

“I am delighted to announce the appointment of Iain Mansfield as Principality’s next chief executive, subject to regulatory approval. It is clear that the breadth and depth of his expertise and experience are exactly what the Society needs to take forward our ambitious strategy. His experience will be invaluable as we navigate the next chapter.”  

Commenting on his appointment, Iain Mansfield said: “It is a real honour to be appointed chief executive at Principality Building Society – a 165-year-old business with a rich history. Julie-Ann leaves the Society in a strong position, and I look forward to working with the board, colleagues and members to accelerate our transformational journey to ensure we are fit for the next generation.” 

Julie-Ann Haines commented: “It has been such a privilege to lead Principality through what has been a truly transformational period. Together, we have helped thousands of people into homes, supported our savers and delivered a real and lasting impact through our partnerships and initiatives. I have been so proud to lead our dedicated and passionate colleagues, to share in their achievements, and confident that the business will continue to thrive under new leadership.”
