Good Energy sources its electricity from UK renewables like Cornish sunshine, Scottish wind and Welsh water. Founded in 1999, it was the first electricity supplier to have a 100% renewable fuel mix. Over a decade later, its mission to help tackle climate change and create a secure energy future stands as strong as ever. It supports a growing community of over 55,000 independent generators across the UK and is investing in new sources of renewable power.


Good Energy has been voted top of the Which? customer satisfaction survey three out of the last four years and has consistently topped Ethical Consumer’s survey as the best green electricity supplier. But none of this means it has to cost more than the standard suppliers.
