Octopus Energy is the UK's most awarded energy supplier — and the reason millions of households are switching using the Octopus Energy referral offer.
Octopus Energy was founded in 2016 with a mission to make energy fairer, greener, and more affordable for everyone. In less than a decade, it has grown from a startup to the UK's largest energy supplier by customer numbers, with over 8 million households on supply.
The company is built on a proprietary technology platform called Kraken, which powers its customer service, billing, and smart tariff infrastructure. This technology advantage allows Octopus to offer innovative tariffs like Agile Octopus and Intelligent Octopus Go that no traditional supplier can match.
Octopus Energy has been named Which? Recommended Provider for nine consecutive years — the only energy supplier to achieve this. Its Trustpilot rating of 4.8 stars from over 776,000 reviews places it far ahead of any other large UK energy supplier.
Beyond the UK, Octopus Energy has expanded to operate in Germany, France, Spain, Italy, Japan, New Zealand, and the United States — taking its technology and green energy mission global.
Octopus Energy's track record of awards and recognition is unmatched in the UK energy industry.
