Tim Lunel

Project Manager for Cosy Homes Oxfordshire

Tim is an experienced project manager. He was Chief Executive of The National Energy Foundation 2005-2012, and is Chair of the Microgeneration Certification Scheme – so he has been working in the home energy sphere for much of his career, during which time the technologies to improve the fabric of buildings and low carbon technologies have improved significantly, and the UK has made progress in decarbonising its grid.

Tim is Treasurer of Hook Norton Community Land Trust and has led the project to get planning permission for 12 new-build PassivHaus homes. He is 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 recognises achievements in renewable and sustainable community energy.
