We're making energy fair, clean, and simple for all using technology.

Powering over 6 million homes in Britain and abroad with award-winning customer service and innovative green energy offers, while building a more sustainable energy system for tomorrow.

Being the UK's most awarded energy supplier is about more than offering the cheapest deals.

We keep our costs far lower than other suppliers so we can pass savings on to you. In the energy crisis, we've shouldered more than £150 million to give our customers the lowest variable tariff in the UK.

Octopus energy specialists helping a customer

Our business is built on outrageously good customer service. If you need help, a knowledgeable, friendly human will be there for you.

9 times out of 10, we'll solve your problem in a quick call or a couple of emails – Which? found we're one of the fastest suppliers to reply.

And if we ever get it wrong, we'll put it right. You can even speak directly to our most senior team by emailing greg@octopus.energy.

In tough times, we look after people, and give extra help to those who need it most.

We make our communications simple and transparent. You can get the most important information up front in an email rather than hunting through a password-protected account. We put you in control online, and continuously build new ways to make your experience even better, from a game-changing balance forecast tool to a prize wheel you spin whenever you give a meter reading. Explore your online account.

And we constantly push to make energy better. Tirelessly campaigning for fair protections for customers. And building innovative technologies that forge a path to a green energy system.

Powering the world's transition to renewable energy

In 2016, we were a tiny British energy supplier, disrupting a broken industry. In 2022, we power homes in the UK, Germany, the USA, Japan, Spain, Italy, France and New Zealand with green energy. And more than a supplier, Octopus Energy Group is a global energy transition collective. 10 businesses working across 4 continents to tackle energy transformation at nearly every front.

Our mission has the backing of some world-leading businesses. From Day 1, we've had the support of Octopus Group, a pioneer of renewable energy investment.

Since then, we've taken over a billion in funding to export Octopus all over the world and transform legacy energy businesses into sustainable ones fit for the future.

Our investors include Origin Energy, Tokyo Gas, CPP Investments and Generation, the sustainable investment fund co-chaired by Al Gore.

Octopus is a living example of the kind of company that Generation was founded to invest in. A company that is a true enabler of a sustainable system led by a mission driven team.
