I have worked with Professional Energy Purchasing since the business started six years ago. Their service has been crucial in helping us effectively manage our energy costs for both gas and electricity which is extremely important to us as a manufacturer. They have also expertly managed and implemented a new electric substation at our Sheffield site which allowed us to safely expand our operation. The exceptional service that Linda and her team provide is second to none, and their personal approach makes them feel like they are part of our business. I would have no hesitation in recommending them to others.
