Although many smaller suppliers like Good Energy have been bought out by much bigger companies, this isn't the case for them. They're still owned by the same people since the companies inception in 2003, though they have sold of shares (in2016 they sold of 7% of the company to Ecotricity, which has increased up to 25% in the following few years). The company is primarily owned by founder and still current CEO Juliet Davenport.
