OCS Strengthens Technical and Engineering Capability With Completion of EMCOR UK Acquisition

A Major Step in OCS’s Global Growth Strategy

OCS has officially completed the acquisition of EMCOR UK from EMCOR Group Inc., marking a key milestone in the company’s global expansion and capabilities. The integration brings together two leading hard services-led facilities services organisations, enhancing OCS’s engineering expertise and reinforcing its ability to support customers in complex and critical environments. 

Expanding Technical Capability Across the UK and the Wider OCS

This acquisition follows the purchase of FES FM and FES Support Services in 2024, further strengthening the Group’s technical and engineering capabilities. The combined division in the UK will include more than 7,000 engineers and with annual revenues exceeding £1 billion, forming one of the largest hard services providers in the country. This increased scale enhances OCS’s broader global capabilities, supporting customers in regions where regulated environments and asset resilience are vital.

Supporting Global Customers Across Regulated and Critical Sectors

The integration combines long-standing expertise across defence, data centres, government, healthcare, life sciences, and commercial property. This enhances OCS’s ability to support global and multinational customers operating in technical and highly regulated environments, where consistency, compliance, and safe delivery are crucial to maintaining service continuity. 

Advancing Energy Services and Technology Enabled Engineering

Both organisations bring recognised strengths in asset data, performance insight, and predictive maintenance. These complement OCS’s established Energy Services capability worldwide, supporting customers with energy management, decarbonisation strategies, compliance, smart building controls, and data-led engineering approaches that enhance performance, transparency, and resilience across multiple regions. 

Supporting a Coordinated Global Integration

Over the coming months, colleagues across the OCS will collaborate to ensure a smooth and coordinated integration. This transition will foster shared learning, consistent service standards, and a unified approach to engineering excellence across regions. The integration will continue to be guided by OCS’s mission to make people and places the best they can be, while delivering strong outcomes for customers and communities worldwide.
