The Wilmott Group, a leading UK critical specialist, has entered into a tentative agreement to be acquired by Rehlko, formerly Kohler Energy. The move marks a hugely exciting new chapter for The Wilmott Group and significantly strengthens the company’s ability to deliver industry-leading, innovative solutions across data centres and other critical infrastructure sectors, such as healthcare, manufacturing and utilities.
As part of Rehlko’s EMEA operations, The Wilmott Group—including WB Power Services (WBPS) and Wiltech Acoustics, will gain access to expanded resources, global expertise, and new manufacturing and engineering capabilities. This partnership will allow The Wilmott Group to better support valued customers across its 19 UK locations and over 4,000 active sites, while accelerating growth in key markets throughout the UK and Europe.
“This is a hugely exciting and pivotal moment for the Wilmott Group,” said Andy Wilmott, Co-CEO and Chairman of The Wilmott Group. “Rehlko shares our deep-rooted commitment to long-term customer value, innovation, and operational excellence, values that the Wilmott Group were founded upon back in 1983. By coming together, we are uniquely positioned to elevate our impact—delivering even greater levels of reliability and innovation to mission-critical operations across the UK and EMEA.”
Rehlko is a global leader in energy resilience, with a reputation for powering the most demanding applications—from data centres to hospitals and industrial operations. This acquisition brings together Rehlko’s extensive, global portfolio with The Wilmott Group’s full-service capabilities in design, testing, installation, and lifecycle support across engineering and acoustic technologies.
Through this integration, WBPS will partner more closely with Rehlko’s engineering teams to scale complex data center projects, reinforcing both companies’ leadership in the sector across the UK and EMEA. In addition, Wiltech Acoustics’ advanced in-house acoustic manufacturing capabilities will enable shorter lead times and improved responsiveness to dynamic market demands.
“The Wilmott Group’s dedication to creating long-term value with customers strongly complements Rehlko’s commitment to delivering innovative and reliable energy solutions,” said Brian Melka, President and Chief Executive Officer of Rehlko. “In this new chapter for Rehlko, The Wilmott Group’s long history of success will bolster our data center solutions across the U.K. and the rest of Europe.”
The Wilmott Group remains focused on its core mission: providing dependable, high-performance power solutions that help sustain vital operations. Now backed by Rehlko’s global scale and investment, the company is poised to reach new heights in reliability, resilience, and service excellence.
