He replaces Rebecca Hopewell who is retiring.
Fletcher joins from Quintain Living (formerly Tipi) and will take up his role at the beginning of January 2021.
Watkin Jones CEO Richard Simpson said: “Rebecca has been the driving force behind the creation of a recognised leader in the residential for rent property management sector. On behalf of the group, I thank her for her enormous contribution and wish her well going forward. Stepping into her shoes, we are fortunate to have an established business leader with a track record of success built on the combination of strategic insight, operational experience and consumer-driven innovation. Jeremy’s appointment positions us well to drive the next stage in Fresh’s growth by delivering the best possible solution for both its clients and the people who live with us. I am looking forward to working closely with him on this and the group’s wider development.”
