Customer satisfaction is at the heart of what we do. Take a look at our profiles below and see what we're all about! 




Alex's background is in micro biology and he had a stint working for Earth Energy.  He has always had an interest in renewables and started OHR twelve years ago in partnership with Karl Breeze (AV), buying Karl out and becoming sole director five years ago.
