Rehlko Uninterruptible Power is part of global energy specialist Rehlko, providing reliable, innovative and energy-efficient power protection solutions for organisations across a wide range of industries. The company combines advanced technology with extensive technical expertise and support throughout every stage of a project, from initial consultation through to installation and ongoing service.

Established in the UK in 1997 as Uninterruptible Power Supplies Ltd, the business has built a strong reputation for quality, innovation, reliability and excellent customer service. Over the years, it has played an important role in introducing new UPS technologies to the UK market, including three-phase transformerless and modular uninterruptible power supply systems.

Rehlko takes a consultative approach to power protection, working closely with customers to identify solutions suited to their individual operational, technical and commercial requirements. Its experienced team supports businesses with the design and implementation of resilient systems designed to protect critical equipment and maintain continuity when mains power is interrupted.

The company's comprehensive power protection portfolio includes uninterruptible power supplies, generators, emergency lighting systems, medical isolated power supplies, battery banks and UPS and battery monitoring solutions. These are complemented by a wide range of support services, including maintenance, repairs, battery services, monitoring, on-site support and equipment hire.

Following its acquisition by Kohler Power Group in 2008, the business became Kohler Uninterruptible Power in 2019. In 2024, Kohler Energy rebranded as Rehlko, bringing the UK operation under the Rehlko name. Today, Rehlko Uninterruptible Power continues to build on more than 25 years of experience, helping customers create resilient, efficient power systems backed by knowledgeable engineers and 24/7 service support.
