Travis Perkins’ chief operating officer John Carter will become deputy chief executive in the new year.
The move comes after a reorganisation that has seen the creation of four divisions for the group’s operating businesses.
The new deputy chief executive role combines the four divisions with the wider group of central functions, including IT and customer development.
Chairman Robert Walker said: “This promotion recognises the outstanding part that John has played, and continues to play, in the success of our business. He is a first class senior executive and we look forward to his contribution to the future development of the group.”
