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. During the energy crisis, we shouldered more than £150 million to give our customers the lowest variable tariff in the UK.
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.
