Specialising in grid and power connections, the Scunthorpe-based firm has 20 years of experience in the design, delivery and maintenance of high voltage power connections across a broad range of sectors, including local authorities, commercial developments and power generation sites.  

Blue-chip customers include Canary Wharf Group, Cemex, Centrica, PepsiCo and RWE.  ESM also has certified transformer and switchgear installation capabilities.

The acquisition of £25m turnover ESM Power will enhance Mitie’s expertise in the growing high voltage power connections market.  

On completion of the transaction, ESM Power’s 60 engineering designers and specialist high voltage installers will join Mitie’s £1.1bn Projects business, which delivers transformational projects across buildings infrastructure, decarbonisation technologies, fire & security and telecoms infrastructure.

ESM Power complements Mitie’s recent acquisitions of Rock Power Connections and G2 Energy, which specialise, respectively, in low voltage (primarily electric vehicle charging) and very high voltage power connections.  

Together, the three businesses will enable Mitie to offer a full suite of power connections services of any size and voltage.

Mark Caskey, managing director – Mitie Projects, said: “This acquisition strengthens our position as a leading provider of power connections in the UK, offering our customers a comprehensive range of design, delivery and maintenance capabilities to support their decarbonisation and asset resilience objectives.

“It is a continuation of the group’s strategy to invest in high growth, high margin companies that enhance our full asset lifecycle Projects business.  We look forward to working with our new colleagues.”
