Our Story

Constant Power Services are always searching for opportunities to ensure all our customers and future customers receive the very best service at all times, which is why we were thrilled to share with you last week the grand opening of our new office and 4,000 sq ft warehouse on the outskirts of Glasgow.

With this new business development, we can respond significantly quicker to stock requests and spares in the North of England, Ireland and Scotland; ensuring optimum business operation is achieved at all times.

News – Constant Power Services opens new office in Scotland

What a year……

An exceptionally unusual year with the COVID virus causing changes across the Globe.

Constant Power Services worked with Bender UK and supported many of the Nightingale projects
(emergency COVID hospitals).  As a company, we could not be prouder to have been able to provide assistance.

We have launched the Datawheel this year, a tool designed for specifiers, facilities managers, and electrical contractors and is a simple convenient way to identify the size and model UPS you require.

Logo changed

With the business growing and adapting to the requirements of its customers, so came the need for a new logo, to represent the brand.


Out with the old

and in with the new



We moved

Following another period of growth, Constant Power Services moved to a new office site in Letchworth.  This has given us a huge warehouse space of over 1600 square meters and doubled our office capacity.



Our partnership with Elcos generator solutions is confirmed.

This year saw our partnership with Elcos bloom with successful installations of many UPS and Generator packages across the UK.



Our offices expanded

Our warehouse and office space doubled as our business has grown.  Constant Power Services can now hold more stock and can enhance the internal back-office functions.

We became part of the Riello Elettronica group.

A big year for Constant Power Services as it becomes part of the Riello Elettronica group.  Giving us access to a wider range of UPS and expanding our offer.



This year saw Constant Power Services expand its reach by appointing an agent in Scotland.

We were formed

In the very beginning, Constant Power Services started trading from Peterborough by the end of 1989 with work increasing we had acquired our own premises in Hitchin.  It is fair to say, we have never looked back.

This is a high quality versatile UPS but the documentation and supplied software is not good enough for inexperienced users. My application, providing safe shutdown of the office PC in the event of mains power interruptions, took several days of experimentation to configure and the manual omits much key information.

At fairly short notice we required a new UPS system installing in our building. We called CPS and from start to finish, the service was second to none from communication, delivery and installation. I would have no hesitation in recommending CPS for your UPS needs. Chris Kehoe Lead Engineer One Snowhill, Birmingham

Absolutely amazing company , providing the top end of customer service! We work at a critical healthcare establishment, and had an urgent issue with our UPS. We contacted CPS and their engineer calmly talked us through the issue. He was currently stationed in Glasgow, and to give us confidence, he was willing to travel all the way to Liverpool to solve the issue and carry out the physical switching. The engineer arrived within 4 hours and presented himself with impeccable customer service skills. Once he attended the issue, he calmly resolved the issue , and the system was back online without any interruption. I cannot underestimate the importance of having such a reliable and competent company on the books. What an amazing service!!!! Many Thanks Paul McNally Vinci Facilities
