Our Ethos




Clean Energy For All



Robin and Jon met at pre-school aged 3 and have been firm friends ever since. After linking up with Aaron aged 11, sometime later the idea for Cotswold Energy Group was born.


We believe that sustainable and renewable energy solutions should be available to everybody.   


We also believe that when the government supports an initiative for people to migrate to clean heat sources and help to save our planet, we should be at the forefront of making it happen. We work extremely hard to ensure that you are delighted and satisfied when you work with us. 


We’re always respectful and aware that we’re often coming into your home to provide a service.  For that reason we will only ever send people to you that we would welcome into our own homes.   


Clean, polite, respectful, professional and qualified.
