Jonathan Cowdrill is a Director at Seven Hills Solar. Colleagues describe them as "While not directly a member of Transition Highbury, I have been involved in Transition Town circles for the last couple of years (TT Hackney primarily). While the Hackney project has trod water a little bit, I have been very impressed with how Jon and the other TT Highbury people got theirs motoring along nicely. They've put in a lot of energy, and have had a direct tangible result, in a remarkably short time, with the setting up of their community garden."
