Barratt has recruited Neil Cooper to take over from David Thomas, who is moving up to become chief executive next month when Mark Clare stands down.
Neil Cooper is currently group finance director of William Hill. He was Bovis finance director from 2007 until 2010. Before that he worked for Whitbread, having initially qualified as a management accountant with Reckitt & Colman and spending time as a consultant for PricewaterhouseCoopers' management consultancy practice.
He is also a non-executive director of Pennon Group, the parent company of South West Water and Viridor.
Barratt chairman John Allan said: "I am delighted that we are appointing someone of Neil's outstanding calibre and experience to the board as CFO in succession to David who steps up to the role of CEO on 01 July 2015."
David Thomas said: "Neil has a strong CFO track record as well as a good knowledge of the house building sector. He has been a key part of shaping the direction of Bovis Homes and William Hill and is an exceptional appointment for Barratt; I am confident that he will add real value to our business."
