Huddersfield facilities management company Core Facility Services has merged with FM Energy. Core will take over FM Energy's portfolio of commercial and charity clients, and extend its range of energy purchasing, efficiency and bill validation services. The deal supports its sustainability management unit in particular. Core now employs 70 people in Yorkshire and expects to make a number of strategic hires over the next 12 months to strengthen all four of its business areas - energy, estates, waste and IT - as it begins to expand its footprint beyond Yorkshire.
