FES

What FES does

FES Group Ltd (formerly Forth Electrical Services) is a UK-based, family-owned independent technical services company headquartered in Stirling, Scotland, founded in 1963 by Duncan Fletcher. The company provides integrated building services covering mechanical, electrical and plumbing (MEP) installation, off-site prefabrication of service modules, digital engineering with BIM Level 2 and 3D scanning, sprinklers, and hard facilities management. It operates an in-house Training Academy in Stirling and the OES (Offsite Engineering Solutions) division for renewables and off-grid systems, supported by 2,000+ staff across 14 UK regional offices.

Its customer base spans public sector clients — NHS Scotland, Glasgow City Council, South Ayrshire Council, and major Scottish universities — alongside private enterprises such as Barclays, Diageo and ThermoFisher, with landmark projects including the Louisa Jordan Hospital, Glasgow's Burrell Collection Renaissance, the University of Edinburgh Advanced Computing Facility, and the Diageo Johnnie Walker Princes Street visitor experience. The company serves as principal contractor and specialist M&E subcontractor on tenders through public procurement frameworks such as the Scottish Government NPD and hub East Central Scotland.

FES generates revenue through project-based professional services contracts (MEP design, installation, principal contracting) and managed services (hard FM and lifecycle maintenance), with pricing negotiated per project rather than publicly disclosed. Distribution is direct enterprise field sales targeting public-sector frameworks and large commercial developers. The company has been positioned as a Top 10 UK building services contractor and was the first building services and FM company globally to achieve both the UN Climate Neutral Now Initiative and the Carbon Neutral International Standard.
