The best-loved energy supplier in the UK

We've gone from a tiny startup supplier to a global leader in just 5 years, and through that relentless growth we still put customers at the heart of everything we do. That's how we've got five stars on TrustPilot based on over 70,000 customer reviews and why consumer champions Which? have named us a Recommended Provider for the last four years in a row.

We're fighting to make energy fairer, more affordable, and more accessible for all. Jump to customer operations roles.

What it's like to work at Octopus

We’ve got an important, urgent mission to bring affordable, green energy to the world, and every person at Octopus works relentlessly to make that change happen fast.

We work with freedom and responsibility. You'll get a lot of trust to run with ideas and take ownership of what you do.

Our founder Greg has a theory that building a great team should be like building a dry-stone wall: rather than forcing people into 'cuboids' and sticking them together in neat little rows, we take authentic humans, and find ways for them to fit together naturally to form a truly solid team full of unique perspectives and strengths. This way of working isn't for everyone. You have to drive your own work forward; be agile, flexible, and personally accountable for everything you do, from idea to conception.
