Mechanical and electrical engineering for data centres, power systems, and water treatment
TES Group designs and manufactures mission-critical infrastructure—LV switchgear, control panels, PDUs, and process automation systems—primarily for data centres, water treatment, and industrial sectors. The tech stack is heavily weighted toward Autodesk design and modelling tools (Revit, Plant 3D, Navisworks, Inventor, CAD), with project management via Primavera P6 and Microsoft Project; the absence of any adopting or replacing signals suggests a stable, mature toolchain focused on engineering delivery rather than digital transformation. Hiring remains engineering and design-focused with senior and lead roles concentrated in the UK, pointing to a specialist services model where technical depth matters more than headcount velocity.

TES Group is a UK-based mechanical and electrical engineering services firm founded in 1999, headquartered in Cookstown, Co. Tyrone. The company operates across four core domains: data centre infrastructure (switchgear, PDUs, E-house configurations), industrial process control and automation, water treatment (municipal, industrial, domestic), and wastewater treatment. Projects span design, manufacture, installation, and commissioning, delivered as turnkey or modular solutions. Active work includes BIM coordination (clash detection, asset information models, COBie registers), P&ID production, containerised power system modelling, and quality system implementation. The firm positions itself as a technical partner in specialist sectors rather than a transactional supplier.
TES uses Autodesk Revit, Plant 3D, Navisworks, Inventor, and AutoCAD for mechanical and electrical design, plus Primavera P6 and Microsoft Project for project delivery. Excel and PowerPoint support documentation and planning workflows.
TES serves data centres, water and wastewater treatment (municipal and industrial), factory automation, quarrying, and commercial sectors. Core offerings include switchgear manufacture, control panels, process automation, and turnkey treatment solutions.
