Martin Reason (pictured) will be retiring as chief executive of The Melton this summer.
Reason has been chief executive since 2006, and is one of the longest serving building society chief executives.
His successor will be Simon Taylor, who was chief operating officer at the Nottingham Building Society from 2011 to 2019.
Taylor was most recently interim chief commercial officer at the Saffron Building Society.
He will join the Melton on 1 June 2020.
Reason said: “I am proud to have witnessed the transformation of the Melton and the part I have played alongside my colleagues in making it a better, more profitable modern Society that continues to be relevant to its members.
“Social responsibility and care for our community is at the heart of the society and it is rewarding to see the difference it makes.
“I will greatly miss the people I have worked with over the years, but feel happy in the knowledge that I will be leaving the society in the very capable hands of Simon.”
