Who Is So Energy in the UK?

So Energy began in the UK in 2015. The two school friends, Simon and Charlie, wanted to make an energy supplier that used renewables. At that time, people in the UK did not feel good about they’re energy suppliers. So Energy promised to be simple and honest, and to give great value to UK homes.

In 2021, So Energy joined up with ESB Energy. This made it stronger. Now, it is one of the main suppliers in the UK. So Energy gives people more choices. Today, So Energy gives gas and renewable electricity to more than 300,000 UK homes. The company’s tariffs help people use greener electricity in their homes.

Every fixed rate tariff from So Energy uses power that comes only from 100% renewable energy sources like wind, solar, hydro, and biomass. When you join So Energy, you can get a vote each year about which renewable energy sources you want for your power supply. This makes it clear for all of us. So Energy also puts solar panels and home batteries in people's homes. The aim is to help people save money on their energy bills and lower their carbon footprint by using more renewable energy.

Customer service is key for So Energy. So Energy holds an "Excellent" score on Trustpilot. It has also been given awards from Uswitch because people feel good about their service. So Energy offers online accounts and smart meter help. Bills are made clear and easy to read. These things let people keep track of their energy with a smart meter.
