Debbie White joined company in September 2017

Interserve is rejgging its business after its chief executive of more than two years said she was leaving at the end of next month

The firm, which employs more than 40,000 people, said White had said she would be leaving the firm back in March 鈥 the month when it went into administration.

It came out of its brief administration under the control of its lenders, delisting from the London stock exchange.

Debbie White (pictured), who began an immediate restructure of the business when she joined in September 2017 under an initiative called Fit for Growth, admitted: 鈥淭he past two years at Interserve have been the most demanding of my professional career.鈥

Speculation about the break-up of the business is now set to increase following the restructure which will see its three main operating divisions with its own chairman and managing director.

The role of chief executive will not be replaced in the new company operating model, the firm said. Group wide functions will be led by Mark Morris, executive director and chief financial officer.

The three divisional chairs will sit on the group board and report directly to group chairman Alan Lovell.

Interserve鈥檚 construction arm will be chaired by former Balfour Beatty executive Nick Pollard, an existing group non-executive. Paul Gandy, who joined from Kier last month, will continue as the managing director of the business.

Its equipment services division that specialises in formwork and ground-shoring for major infrastructure projects will continue to be led by chairman Ken Hanna, the chair of power provider Aggreko, and Ian Hayes as managing director.

And Lovell will chair the support services division, which will be run in an executive capacity by Lynn Mawdsley, Interserve鈥檚 former deputy chief financial officer.

White, who joined from services firm Sodexo, replaced Adrian Ringrose who had spearheaded its disastrous move into the energy-from-waste sector which landed it with crippling losses of more than 拢200m.
