TES Group, a specialist electrical engineering firm based in Northern Ireland, has been acquired by French group Legrand in a deal that provides an exit for private equity owner Foresight Group.
Founded in 1999 to provide water and power technology engineering expertise specialising in critical infrastructure, TES Group has expanded to comprise two divisions serving separate end markets.
TES Power specialises in designing and manufacturing high-spec low voltage power distribution equipment, primarily used within data centres. TES Water, meanwhile, provides mechanical, electrical, instrumentation, control, automation (MEICA) design and build services to UK and Ireland water and wastewater utility providers.
The deal will deliver a return of 4x Foresight’s invested funds. Since Foresight initially invested in the group in 2024, it has seen a period of strong growth, expanding to 280 staff working across two manufacturing sites in Northern Ireland.
Backed by Foresight, TES had undertaken significant investment in its facilities, expanded its head office and manufacturing site in County Tyrone and opened the TES Power Data Centre campus in County Derry, enabling it to meet a major increase in global demand for its products.
TES Managing Director Noel McCracken said that Foresight’s backing had been “instrumental in our evolution from a regional specialist to a major European player in critical power and water infrastructure.”
McCracken also said that, beyond the financial aspect, Foresight’s focus on sustainability and social values had helped to accelerate the company’s ESG initiatives.
Brian Taylor, CEO of TES, added:â¯"The partnership with Foresight has been a pivotal chapter in the TES story. Their investment provided the capital and the confidence to scale our operations rapidly, particularly as we addressed the surging global demand for data centre infrastructure.”
Taylor said that Foresight’s backing and guidance had helped TES to “professionalise our processes while maintaining our entrepreneurial culture” and added that joining Legrand would enable the company to move into a new phase of international expansion.
Graeme Mckinstry, director at Foresight Group, said: "Led by a highly impressive management team, TES is an excellent example of our unique commitment to investing in growing companies across the UK and Ireland.”
"TES has established itself as a leading provider of power distribution equipment across the European datacentre market and remains a trusted supplier to UK and Irish critical infrastructure network providers.”
