About us

Our team


Erica Charles

Managing Director

Erica started Spirit at the end of 2009, having become increasingly excited about the benefits that renewable energy can bring both in meeting our energy needs and in reducing CO2 emissions. She has a first class degree in Pure Mathematics from Oxford University (1990), and more recently a masters in Applied Mathematics and Scientific Computing (2007), also from Oxford University, during which she investigated the mathematical solutions of the problem of using fixed (non-tracking) mirrors to maximise the concentration of the sun’s rays on solar panels. Erica has had a longstanding interest in green issues. Prior to launching Spirit she ran a Low Carbon Day for schools which took place in June 2010, supported by over 1600 schools. She is also a serial entrepreneur, having previously started www.primrose.co.uk, now run by her husband, Ian Charles.

She makes sure we stay up to date with all that “stuff” in the office; whether it’s health and safety, staff training or electrical tester calibration, Anne Marie is on the case. She also makes a mean cup of tea and some very fine brownies.
