Mansfield will serve as CEO designate from 13th October, with a formal transition date set for November.
He has been chief financial officer since 2022 and a board member since 2019.
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.”
Simon Moore, chair of the board, said: “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.”
Moore added: “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.”
He said: “We are grateful for her efforts, and wish her every success in her new role which she will commence in the middle of 2026.
Haines said: “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.”
