Kohler Uninterruptible Power UK

What Kohler Uninterruptible Power UK does

Kohler Uninterruptible Power UK, legally Rehlko Uninterruptible Power Ltd., is a UK-based specialist in critical power protection, headquartered in Hook, Hampshire, with a headcount of 76. The company designs, supplies, and services uninterruptible power supply (UPS) systems (single-phase and three-phase), battery solutions, BS EN50171-compliant static inverter emergency lighting systems (the Rehlko EL Series), standby generators, and prime power systems, alongside associated controls and switchgear. These products are deployed in data centres, banking and financial services, healthcare, government and defence, emergency services, pharmaceutical and biotechnology, manufacturing, and life-safety applications where power continuity is operationally or legally mandatory. The business is currently transitioning its corporate identity from the legacy Kohler Uninterruptible Power brand to the Rehlko brand, with a Rehlko corporate parent ecosystem that includes generator and prime power manufacturing.

The company operates a direct enterprise field-sales model, selling quote-based, project-specific solutions to large public- and private-sector customers, supported by a 24/7 nationwide field-service engineer network for maintenance, repairs, battery replacement, monitoring, on-site support, and equipment hire. Revenue is generated from two streams: hardware sales of UPS systems, batteries, emergency lighting, and standby generators; and recurring professional services tied to the installed base. Marketing is conducted through a consultative, education-led approach, including the Rehlko knowledge base (KVA load calculator, UPS handbook, technical glossary, whitepapers, case studies), the UPS Academy and CPD training programme, exhibitions, and a presence on LinkedIn and YouTube. Disclosed named customers include Rapiscan Systems (security inspection), Cossham Hospital / North Bristol NHS Trust, the UK's largest electricity transmission and distribution business, and Pharo Management (financial services), indicating a multi-vertical enterprise footprint rather than dependence on a single end market.

The business is privately held as part of the Rehlko group, holds ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and SafeContractor certifications, and operates exclusively in the United Kingdom. There is no public revenue, funding, or M&A disclosure; growth direction is inferred from the 2023 rebrand, product-line extension into emergency lighting, expansion of the addressed industry verticals to 12+, and continued reinvestment in service and certification infrastructure, consistent with steady, moderate growth in a mature UK critical-power market.
