What OCU Group does
OCU Group is a UK-headquartered, private equity-backed multi-utility infrastructure services specialist that designs, builds, and maintains regulated infrastructure across electricity, rail, water, gas, and telecoms markets. The company operates from a Stockport headquarters and more than 40 UK sites, employing between 1,001 and 5,000 staff, with international operations extending into Ireland, the Netherlands, Australia, and New Zealand. Its core service lines span Energy Transformation (battery energy storage, solar, wind farms, EV charging, microgrids, HVDC, EPC, substations), Power Transmission and Distribution for Distribution Network Operators, Water and Environmental infrastructure including trenchless technology, Digital Infrastructure (fibre installation, termination, testing), Horizontal Directional Drilling, and District Heating networks.
OCU generates revenue through professional services contracts with enterprise utility clients, including Distribution Network Operators, water utilities, and renewable energy developers, priced on a quote-based or project-specific basis within multi-year framework agreements. The business is privately held by European private equity firm Triton Partners, which acquired the company in late 2022 and has funded an aggressive buy-and-build strategy that has taken reported revenue past £800 million. Notable proprietary technology includes 'George', a first-of-its-kind 200-tonne Multi-Diameter Pipe Pusher enabling slip-lining of water mains up to 2 km in a single pass, and the OCU Evolution sub-brand delivering end-to-end EV charging infrastructure via an integrator model that combines multiple hardware and software partners. Acquired brands including RJ McLeod, OCU Hornbill, OCU Northavon, OCU Modus, OCU Opals, Athena PTS, and Volta Energy Group retain operational identities while contributing to a consolidated services platform.
