What The Wilmott Group does
The Wilmott Group is a privately held UK family-owned holding company headquartered in Eastwood, Nottingham, that operates two wholly owned subsidiaries — WB Power Services Ltd (established 1983) and Wiltech Acoustics Ltd. WB Power Services provides critical power solutions to UK enterprises, including generator sales and installations, generator and UPS equipment hire, ongoing maintenance services, and renewable and hybrid power solutions; its principal customers are data centres, hospitals, and military facilities, with additional exposure to industrial operators. Wiltech Acoustics engineers, manufactures, and installs noise control solutions for power generation and industrial applications, addressing regulatory and worker safety requirements around noise exposure.
The group operates a B2B direct enterprise sales model with a quote-based pricing structure and distribution limited to the United Kingdom. Revenue is generated through a mix of one-time equipment sales and installations, usage-based generator hire, recurring generator and UPS maintenance subscriptions, project-based noise control engineering, and renewable power installations. Customer segments are concentrated in critical infrastructure and industrial/power generation end-markets, where the integrated power-plus-acoustic offering allows cross-sell between the two subsidiaries. Marketing is executed through the company websites, LinkedIn, Instagram, and YouTube channels for both divisions.
Leadership is anchored by the Wilmott family, with Andy Wilmott serving as Co-CEO and Chairman and Chris Wilmott as Joint Chairman, alongside functional directors covering finance, projects, and HR/QSHE. In July 2025, Rehlko, a Milwaukee-based manufacturer of power generation and renewable energy products, announced plans to acquire The Wilmott Group to expand its European data centre and critical infrastructure footprint; the group continues to operate as an independent entity pending completion of the transaction.

Company assessmentBroad incumbents
- Rehlko (formerly Kohler Power): Milwaukee-based manufacturer of power generation and energy systems; announced acquirer of The Wilmott Group.
