Private equity investor First Reserve now owns MUS, regional contractor Dyer & Butler and the G4S Utility & Outsourcing Services portfolio, which principally includes meter reading, technical energy metering services and data process management services.

The acquisition will also include G4S Locks and Alarms, which provides nationwide, 24/7 locksmith services and inspection specialist G4S Assessment Services.

Private equity investor First Reserve said the metering business would be rebranded as Morrison Data Services and the other associated businesses would become M Assessment Services, LRP Services and ProtectMyProperty.

Jim Arnold, Chief Executive of Morrison Utility Services, said: “Competition for metering and outsourcing is strong and G4S Utility Services’ strong market position, combined with our broad client portfolio and infrastructure construction expertise, will offer our clients a number of new value add services.

“We are excited by the new market opportunities that this acquisition will bring.”
