Who is Octopus Energy?

Founded in 2016, Octopus Energy is a forward-thinking UK energy supplier known for disrupting the traditional utilities market with a tech-driven, customer-first approach. Headquartered in London, the company supplies 100% renewable electricity and affordable gas to over 5 million homes and businesses across the UK as of 2025.

Not Just Another Energy Supplier

Octopus Energy isn’t just another power company — it’s a technology company at heart, using its proprietary platform, Kraken, to deliver exceptional customer service and innovate energy distribution. This same platform powers several other energy suppliers worldwide, showcasing Octopus’s influence beyond its own customer base.

They’re part of the Octopus Group, a wider investment and asset management company overseeing more than £20 billion in assets. The group’s portfolio includes some of Europe’s largest renewable energy infrastructure projects, such as solar farms, wind turbines, and energy storage systems.

Growing Beyond the UK

Octopus Energy has grown rapidly, expanding operations beyond the UK into Germany, Spain, the United States, France, Italy, New Zealand, and Japan, among others. Their mission? To revolutionise energy globally by making it greener, fairer, and smarter — one household at a time.

Octopus Energy's Mission to Decarbonise Energy

Octopus Energy is a company with a clear mission: to make the global shift to clean, affordable energy happen faster. They’re actively working to decarbonise the energy system and build a future where renewable power is the norm, not the exception.

At the core of their business are four guiding principles:

Green – All electricity supplied by Octopus is 100% renewable, sourced from wind, solar, and hydro. Their generation arm also invests directly in large-scale solar and wind farms across Europe.
Fair – Tariffs are simple, transparent, and competitively priced. There are no exit fees, and loyal customers get the same rates as new ones — a rare stance in the energy industry.
Smart – Octopus is a tech-first energy provider. Their cutting-edge Kraken platform automates billing, customer service, and energy distribution, making the entire experience more efficient and scalable.
Human – From plain-English billing to award-winning customer support, Octopus puts people first. Their team is UK-based and highly rated, often praised for solving problems quickly and honestly.

Their efforts are already making an impact: millions of tonnes of carbon emissions are avoided each year thanks to their growing portfolio of renewable energy projects and smart grid innovations. Whether it’s rolling out time-of-use tariffs that reward off-peak energy usage or powering electric vehicles with off-grid solar, Octopus Energy is helping to reshape the energy ecosystem — for good.

Powered by Technology: The Kraken Platform

One of Octopus Energy’s greatest innovations is its proprietary technology platform, Kraken. Far more than just back-end software, Kraken is a revolutionary energy management system built to automate, optimise, and transform the way energy is supplied and consumed.

Designed in-house, Kraken is the engine behind Octopus’s seamless customer experience and dynamic pricing models.

The Tech Behind Octopus Is Revolutionising the Entire Energy Industry

Kraken’s capabilities go beyond Octopus’s own operations — it has been licensed by major global suppliers such as E.ON, EDF, and Tokyo Gas, serving over 50 million energy accounts worldwide through its partners. This wide adoption is a testament to Kraken’s efficiency, flexibility, and future-ready design.

By investing in its own tech rather than relying on outdated industry systems, Octopus Energy can move faster, reduce costs, and bring smarter, greener solutions to customers around the world.
