05 December 2025

OCS’ acquisition of the UK building services segment of Emcor has reached its formal completion.

Combined with its acquisition of FES FM and FES Support Services in December 2024, OCS’ combined technical and engineering division will include more than 7,000 engineers and annual revenues exceeding £1 billion.

The sale is valued at approximately £190 million, equivalent to around $250 million at current exchange rates.

Rob Legge, Group Chief Executive Officer of OCS, said: “This acquisition supports our ambition to build the best hard services-led facilities services business in the world, with the skills and scale to deliver what customers need across essential sectors. We are bringing together teams known for their technical depth and commitment to safety, which strengthens our ability to make people and places the best they can be” 

Daniel Dickson, UK and Ireland CEO of OCS, added: “Bringing these businesses together creates a stronger hard services platform for the UK, with deeper technical capability, wider sector coverage and enhanced engineering support for customers across complex and critical environments. The integration of our divisions will give colleagues more opportunities to develop and customers a broader range of integrated services across the UK. Our priority now is a smooth transition that protects service quality for every customer. Both organisations share similar values and a focus on people, so colleagues will continue to deliver with the same professionalism and care.” 

Cheryl McCall, Chief Executive Officer of EMCOR UK, said: “We are thrilled to join an organisation that shares our deep commitment to putting customers and our people at the heart of everything we do. The combined organisation will bring specialist skills to support customers in environments where performance, safety, and reliability matter every day. We look forward to working with teams across the business as we combine our strengths in Facilities Management, hard services, engineering excellence, and innovation across data insights, asset, and carbon management.”
