Octopus Energy Group was launched in 2016 with a vision of using technology to make the green energy revolution affordable whilst transforming customer experiences. Its domestic energy arm already serves over 1.8 million customers with cheaper greener power, through Octopus Energy, M&S Energy, Affect Energy, London Power and Co-op Energy.

Octopus Energy for Business manages over 20,000 customers with proprietary energy offerings. Octopus Electric Vehicles is helping make clean transport cheaper and easier, and Octopus Energy Services is bringing smart products to thousands of homes.

All of these are made possible by OEG's tech arm, Kraken Technologies, which offers a proprietary, in-house platform based on advanced data and machine learning capabilities, Kraken automates much of the energy supply chain to allow outstanding service and efficiency as the world transitions to a decentralised, decarbonised energy system.

In April 2020, Octopus Energy Group became a UK tech unicorn, valued over £1 billion following an investment from leading Australian energy company Origin Energy. With operations in the US, Germany and Australia, Octopus Energy Group's mission to drive the affordable green revolution is going global.
