“My experience dealing with Specialist Power Systems was to encounter a very thorough service with good attention to detail and fast response times relating to queries. As an independent systems integrator they were able to steer us in the direction of the UPS products which best suited our needs as well as arranging the manufacture of bespoke switchgear and provide a specialised installer. I would certainly use their services again and recommend them to others.”

When I started Specialist Power Systems in 2002, my background was a senior UPS service engineer with Eaton Powerware, where I was employed for 10 years. My main objective at Specialist Power has always been to provide the best possible service and customer experience.

If we get that right then everything else should simply fall into place.

I have always maintained that a business is only as good as the people in it and I am very proud to have some of the best engineers, sales team and back office staff in the industry. With almost half of our staff having been with the company for over 10 years, that tells me that we are doing the right things for our employees and that our commitment to excellence is reflected by the shared vision of our team here at Specialist Power.
