Neil Cooper joined Barratt as CFO less than 18 months ago from William Hill. He was previously group finance director of Bovis Homes from 2007 until 2010.
Chief executive David Thomas, who previously held the role of Barratt CFO for six years until July 2015, will reassume temporary responsibility for the finance function, supported by both group financial controller Philip Schumacher and housebuilding financial controller John Flynn.
The board is launching a search for a new CFO and said that a further announcement would be made in due course.
On 12th January Barratt issued a trading update that indicated that the finances were in good shape, bar an expected decline in London completions.
Chairman John Allan said: "On behalf of the board, I would like to thank Neil for his contribution during his time with us and we wish him well for the future."
Neil Cooper himself said: "I wish David and the team all the best for the future and would like to thank the board for the opportunity to work with Barratt over the past year."
