About Graham
Graham graduated from the University of the West of England with a degree in geography and environmental management where he focused his studies on climate change. This gave rise to employment with a renewable technology installer in the role of a project surveyor.
Inspired by improving buildings through renewable technologies, Graham entered the energy assessment industry, starting as an RDSAP assessor offering EPCs, then moving into the new build residential sector completing SAP calculations whilst specialising in renewable technology feasibility and energy and sustainability statements. Graham progressed to the role of technical team leader within the consultancy before leaving to Start E & S Bristol Ltd with Marcus Eves.
After 8 years of running a successful business together we have decided to part ways with Marcus heading to Box20 and Graham starting ThermTechnical.
