He is the Company Secretary of Hook Norton Low Carbon Limited – a low carbon community group that was awarded the status of Energy Neutral Village in 2014 in the ACE Awards (Academy of Champions for Energy), one of Europe’s most high-profile events that recognise achievements in renewable and sustainable community energy.
