This company is friendly and polite with their customers, delivers accurate bills, and best of all, they supply 100% renewable energy. In this article, we do a full analysis of this company, to understand its background, see how good it is, and learn all about it. 

Who is So Energy? 

So Energy came to life as the initiative of Charlie Davies and Simon Oscroft, two school friends who decided to fund a company that helped UK energy customers. Both young entrepreneurs discovered that the UK energy industry had a wide variety of problems, including poor customer service, a lack of green energy generation, prices that were not competitive, and several other faults.

Both partners decided to create a green energy company that focused on providing the best customer service and competitive prices. So Energy was first established in 2015, operating at first with only two employees.

To provide the best service, one of the pillars of So Energy is to only sell green energy. To do this, the fuel mix of the company is comprised of electric power coming from renewable sources like hydro, wind, solar, and biomass energy. All of these energy sources are generated in different locations around the UK.

Due to its extremely good work and outstanding customer service, So Energy was recognized with the Hounslow Business Award of the London Borough of Hounslow. As proof of its excellent service to customers, the company has grown to have a portfolio comprised of 200,000 energy customers in the UK.

Looking to expand its business and adapt to the new technologies, So Energy partnered with Morrison Data and Axpo UK. Morrison Data now handles the smart readings, data management, and installation of smart meters to customers in the UK, while Apox UK helps the company access market commodities and a wider mix of renewable energy sources. 

So Energy Market Share

In the past, specifically around 2008, the Big Six, which are the six larger UK energy suppliers, held around 99% of the energy market share. Since 2011, the UK energy market share has started to shift as new energy companies with better customer service have entered the industry.
