He will be succeeded by his deputy chief executive John Carter.
Mr Cooper will retire completely on his 60th birthday next March but will keep an advisory role for 12 months to help with the development of the Toolstation business.
Under Mr Cooper, Travis Perkins’ turnover has grown from £1.83bn to £4.85bn, market capitalisation from £2bn to £4.1b and pre-tax profit from £190m to £300m. Travis Perkins is now the largest supplier of building and construction materials in the UK and recently joined the FTSE 100 for the first time in its history.
John Carter is a Travis Perkins lifer. He started with Sandell Perkins as a management trainee in 1978 and has since worked in many parts of the business.
Chairman Robert Walker said: "Geoff has made an outstanding contribution to the success of Travis Perkins. He has managed the company through a number of important landmarks and has created and led a management team that is widely regarded as the best in the sector; the culmination of a very successful executive career. He will of course be missed and we wholeheartedly wish him well as he develops his plural career.
"John will be an excellent successor to Geoff. His entire career has been spent with Travis Perkins and he too has made a huge contribution to our success over a long period of time. He is one of the most experienced and highly regarded senior managers in the industry and the board has every confidence that, working with our CFO, Tony Buffin, he will lead our executive team with distinction, and continue to drive the company forward."
