KES Group

What KES Group does

KES Group is a Northern Ireland-headquartered modular manufacturer founded in 2009, operating from a 14-acre purpose-built manufacturing campus at Strabane Business Park. The company runs two principal divisions: Energi X, which designs, manufactures, factory-tests, and delivers mission-critical electrical infrastructure including low-voltage switchgear (up to 6,300A, 100kA short-circuit withstand), E-Houses, E-Skids, package substations, PDUs, power factor correction systems, and SCADA-based power management platforms; and Business X, which supplies premium relocatable modular office workspaces to commercial clients across the UK and Ireland. Primary end customers are hyperscale data centre operators and industrial power users for Energi X, and transport/logistics operators and premium automotive dealerships for Business X.

Underlying technology centres on off-site modular manufacturing combining advanced metal fabrication, precision engineering, and factory-tested electrical integration. The Energi X division holds an exclusive UK and Ireland licence for Siemens SIVACON S4 & S8 switchgear (announced November 2025), enabling global delivery of Siemens-engineered solutions backed by Siemens warranty. The E-House product carries patent approval and the company claims capacity to produce circa 50 large-format E-Houses simultaneously. A SMARTBUILD legacy line addresses commercial, residential, and holiday home modular applications.

The business model is principally hardware sales via direct enterprise field sales for Energi X projects (quote-based, multi-year contracts dependent on specification and capacity) and one-time unit sales for Business X modular buildings (delivered in 7–14 days with finance options from £349/week). All manufacturing, factory acceptance testing, and shipping originate from the Northern Ireland headquarters, with global delivery capability for electrical infrastructure. Triple ISO certification (9001, 14001, 45001), NICEIC, Safe T Cert, SSIP, Constructionline Gold, and Safe Electric registrations support procurement and compliance positioning. Strategic intent is articulated by a £2bn annual turnover target and a workforce expansion plan to exceed 1,100 employees, supported by Phase 2 (completed January 2024) and Phase 3 (underway) manufacturing expansions.
