The engineering contracting division, which turns over around £200m, now falls under control of the property management division.

This leaves the asset management division to concentrate on clients looking to raise their energy performance.

MITIE has split its FM division into two. One concentrating on traditional FM work and the other focused on energy efficiency and low carbon projects.

Last year the firm grew strongly raising staffing by 10% to 56,580, thanks to strong orders and two acquisitions.

Turnover across the diversified  facilities management and maintenance company rose 13% to £1.7bn in the year to March 31.

This lifted underlying pre-tax profits for the period 17% to £92m.

MITIE has launched a CarbonCare service for clients and stamped its mark in social housing after spending £156m buying Dalkia FM and EPS last year.

Chief executive Ruby McGregor-Smith said: “MITIE has made excellent progress in the past financial year, creating a step-change in its capabilities with two strategic acquisitions.

“We are at an exciting stage in the evolution of the business.”

She added: “We have delivered double digit growth in revenue, underlying earnings and dividends.

“We have experienced an extremely positive start to the new financial year with new contract awards.”
