“The whole project was carried out swiftly, on time an in budget. CPS are without doubt one of the most professional and knowledgeable companies in their field that I have had the pleasure of working with. By working through the weekend, and other unsociable hours, they have installed a superb back up system without a single minute of lost sales time.”

“National Grid plc have used the services of Constant Power Services for over 15 years for the design, supply, installation and maintenance of Uninterruptible Power Supply systems form 1.5MVA to 30kVA. I have found them to be an extremely reliable, efficient and dedicated company who will always endeavour to provide support no matter when, or what is requested of them, for example: National Grid recently experienced a complete failure of a static 100kVA unit supporting 24/7 systems at a major National Grid site. The supplier of the UPS (not CPS) stated the UPS was beyond repair and could not source a replacement for several days. After consulting with senior engineers at CPS, a new 125kVA UPS unit was supplied, installed and fully operational within 48 hours. CPS is a company my colleagues and I have come to respect and rely upon and as Engineering Manager responsible for 24/7 operations throughout the UK, I have no hesitation recommending CPS.”
