Engineer Led Values

Founded by the Engineer Who Saw the Overcharging Firsthand

Keson Energy was founded by an MSc Renewable Energy Engineer from Coventry University with 8 years of professional experience designing solar systems. After years designing solar systems for a major UK installer and watching customers being charged two to three times the real cost of their systems, Keson Energy was built to do things differently. Every system we specify is assessed by a qualified engineer at an honest price.

Coventry University MSc

An advanced Master of Science degree in Renewable Energy Systems Engineering from Coventry University.

MCS Certified Partner Network

Every installation is carried out by our vetted network of MCS certified installation partners.
