We believe energy should be better - for you and the environment. 

We believe energy should be better - for you and the environment.  We’re a leading energy technology company providing a better experience for our customers through transparency, honesty and simplicity. Better for the planet, through real long-term investment in renewable generation and a low CO2 future. Better value, by throwing away the old business models of the “Big 6” and instead building a business that’s fit for the 21st century. We make energy green and flexible for consumers, with fair and transparent pricing. Through our home developed platform, cloud-based billing, and sophisticated use of data science, modelling and AI, we’re redefining what is possible in energy.  

Our breakthrough Agile tariff has been widely reported as leading the way in energy innovation, and we’re passionate about fairness – we were first to uncover the widespread strategy of energy company tease and squeeze pricing and following on from this campaign, our CEO and Founder Greg Jackson presented evidence in favour of capping energy tariff prices before the bill committee in Parliament.   

We already supply 100% renewable energy to nearly 2 million homes and over 15,000 businesses (including Arsenal FC and the Cardiff Blues to help them power their stadiums with 100% renewable energy) throughout Great Britain and we’re also the supplier behind M&S Energy. We’re award winning for our disruptive technology and are delighted to be the only energy supplier to pass the rigorous Which? customer service tests and be their only recommended energy supplier for 4 years in a row.   

We also proudly enjoy a 5-star TrustPilot ranking from our customers.  We were named the Company that’s done the most in the past year to advance UK renewables at the REA Awards 2019, and most recently, our proudest award, that of Best Company to Work For.  Our group includes Octopus Energy, Octopus for Business, Kraken Technology, Octopus Electric Vehicles and Octopus Energy Services as well as our new net zero Centre - Octopus Centre for Net Zero. 

We recently secured over £500 million of investment from Origin, Australia's largest Energy Company and Tokyo Gas, to help us continue on our mission.

Octopus Energy buys and balances around £1bn worth of gas and electricity every year. We are currently active in UK, Germany, USA and New Zealand with ambitious global expansion plans (recently announcing an entry into Japan). We’ve developed our own risk and trading technology to help us optimise and automate this important task.
