About Us

Spherenergy are commercial electrical contractors based in Bagshot Surrey. Our areas of expertise are in low and renewable electrical systems, solar panel (PV) installation and off grid systems.

Our commercial electricians are fully accredited for electrical work, through ELECSA, NICEIC, ECA and for our renewable energy services, we are listed with the Renewable Energy Assurance scheme, as well as being MCS accredited as a registered Green Deal Installer.

We offer Off Grid Solutions for remote buildings where access to the electricity grid is not an option. Or for customers who no longer want to pay ridiculously expensive energy bills. As a result of these increasing energy costs, along with the ever decreasing price of solar modules, we believe off grid systems will play a big role in the future of the UK's electricity usage and generation.
