SmartestEnergy is a people-powered energy company, inspiring a greener generation. With our flexibility-backed business model and our vision of a 100% renewable future, we help customers, generators and partners through the complex energy transition towards net zero.

We’re a leading purchaser of independent renewable generation and Environmental Attribute Certificates (EACs) and we provide reliable, innovative clean energy retail solutions to businesses – translating the risks and opportunities of replacing fossil fuels with abundant clean sources.

Through education and engagement, we’re creating a growing worldwide community of renewable energy champions, accelerating the journey towards a better future. Together we’re making the whole system fairer, greener, more transparent and more powerful.

SmartestEnergy was founded in the UK in 2001. Since then, we’ve expanded our retail business from I&C to small and medium enterprises in the UK and established operations in the United States and Australia. We’re a wholly-owned subsidiary of the Marubeni Corporation. As such, we’re a stable, well-resourced business with an independent voice to provide what’s best for our customers.
