Atkinson has run the international ground engineering specialist for 10 years and blamed the growing pressure of travelling for his decision to step down.

He said: “Since I joined Keller in 1990, the group has grown significantly, especially in international markets with the group now working in over 40 countries.

“Particularly during recent years, this has meant an ever increasing amount of overseas travel, which is not something I can continue to commit to.

“I have therefore informed the board of my intention to retire from Keller at the end of 2015, when I will be 55.

He added: “In the meantime, I shall continue to work diligently with the executive team to deliver the group strategy.”

Keller said it had started the hunt for a successor.

Chairman Roy Franklin said, “Justin is a highly effective chief
executive of Keller.

“Under his leadership, and with the support of a strong executive team, the business has undergone significant transformation and operational improvement.

“The timing of this decision provides Keller with continuity of leadership and the necessary time to search for and appoint his successor in an orderly handover.”
