Maintaining Business Continuity For Over 30 Years

Since the late 80’s Constant Power Services Ltd excelled in providing support to businesses seeking quality uninterruptible power supplies, installation and aftercare. We appreciate the complexities of a specification, the time constraints on finalising a project and understand that it can all change in a second, which is why we are the best support for you.

Constant Power Services offer a range of products from smaller 700VA Uninterruptible Power Supplies to 6.4MVA systems, containerised 252kW units for hire or purchase,  generators and switchgear.  Our turnkey solutions are tailored to your requirements.  Working with our customers requires great communication, respect and ownership of a task, a solution, or in some cases a problem to fix.

This is something Constant Power Services prides itself on and that is why support is integral to our business and communication, respect and ownership for our internal values, as they come so naturally to us. Some of our clients have been with us for over 16 years.
