SmartestEnergy is a different type of energy company. We’re changing the way that businesses buy and sell energy, shaping the future energy mix to be more renewable, flexible and smarter.

We are the leading purchaser of electricity from independent generators, with a diverse and growing portfolio, with over 600 independent generators from communities to blue chip companies. Read more about our generation customers here.

We are also a licensed supplier to large industrial and commercial organisations, and are the first company in the UK to have a Carbon Trust Certified 100% renewable electricity supply. We work with over 1,000 business electricity customers from high-street brands to major manufacturers. See some of our customer stories here.

As the UK energy landscape evolves to decarbonise, decentralise and digitalise, we’re already expanding our offering to play an active role in this transition. We help customers and generators capitalise on their flexibility, helping them deliver on their sustainability ambitions and respond to the needs of the National Grid. 

Founded in 2001 and wholly owned by Marubeni Corporation of Japan, SmartestEnergy has offices in Ipswich, London and Glasgow. People are vital to our business and we were awarded the prestigious Investors in People Gold standard in May 2016.
