UPS INSTALLATIONS

For the past five years, OCG has proudly led the way as the principal installer of UPS (Uninterruptible Power Supply) systems across the Transport for London (TfL) network. As the only contractor in the last decade to consistently deliver installations to such a precise, reliable and high standard, we’ve built a reputation rooted in technical excellence and trusted performance.

This commitment to quality has not only set us apart - it has made OCG the preferred contractor for UPS systems on the TfL estate. Our ability to deliver complex, safety-critical projects with precision and consistency has earned the trust of key stakeholders, allowing us to carry out back-to-back installations continuously for five consecutive years.

Our success is built on both deep technical capability and strategic partnerships. We maintain an extremely strong working relationship with Vertiv, one of the largest and most respected UPS manufacturers in the world, allowing us to remain at the forefront of product knowledge, integration, best practices, and support.

Central to our approach is a proprietary methodology we’ve developed over years of hands-on experience. This method enables us to perform installations and changeovers with almost zero risk to the client’s live network, ensuring continuity of service in even the most critical environments.

Building on this foundation, we have begun expanding our footprint across the UK and Europe, now supporting mission-critical UPS deployments for Network Rail and Tier 1 data centres. Whether protecting passenger networks or powering digital infrastructure, our mission remains the same: deliver uncompromising reliability where it matters most.
