What They Do
Octopus Energy has rapidly evolved from a UK energy supplier into a global entity, offering a diverse range of services and products. The company focuses on technology-driven energy solutions, primarily through its Kraken Technologies platform, which utilizes machine learning for customer-centric automation and supply chain management. This platform is licensed to utilities such as EDF Energy and E.ON, supporting over 50 million accounts worldwide (source: octopusenergy.group). Their offerings include 100% renewable electricity tariffs, time-of-use plans, and EV concierge services, catering to residential households, businesses, and global utilities (source: octopusenergy.com). With a strong emphasis on integrating renewable energy sources, Octopus Energy targets customers who are EV owners, solar adopters, and smart home users, providing them with innovative solutions that promote savings through dynamic pricing (source: energydigital.com).
Projects & Track Record
Octopus Energy Generation manages a portfolio of 300 projects across eight countries, primarily focusing on solar and offshore wind energy. With £6 billion in assets, these projects power approximately four million homes, and the company has established a reputation for paying 100,000 UK households for solar exports, generating 1.2 billion kWh annually (source: octopusenergy.com). Notable projects include the acquisition of Zestec Renewable Energy in December 2022, which aimed to expand their renewable energy capabilities, and a carbon-neutral bid deal in Manchester targeting 2038 neutrality (source: wikipedia.org). The company is also actively involved in ongoing initiatives like KrakenFlex, which balances grid energy through the integration of EVs, batteries, and solar technology (source: octopusenergygeneration.com).
Recent Developments
In recent years, Octopus Energy has made significant strides in expanding its market presence. In September 2023, the company completed the acquisition of Shell Energy's UK and German household businesses, which increased its domestic and business customer base to 6.5 million, achieving a 22% market share in the UK by April 2024 (source: wikipedia.org). Additionally, the company announced plans to spin off Kraken Technologies in September 2025, a move aimed at scaling operations to over seven million UK customers and enhancing its energy transition technology (source: youtube.com). These developments underscore Octopus Energy's commitment to innovation and growth in the energy sector.
Working There
Octopus Energy offers a variety of roles across multiple departments, including retail supply, technology development, and renewable energy project management. The company actively hires at its London headquarters, as well as in Manchester, Newcastle, Rotherham, and Birmingham, with employee ratings on platforms like Indeed reflecting a positive workplace culture (3.9/5 in London, 4.2/5 in Manchester, and 5.0/5 in Rotherham) (source: indeed.com). The culture at Octopus Energy emphasizes customer centricity and long-term investment in both people and technology, fostering an environment where employees are encouraged to innovate and contribute to the company's mission of providing sustainable energy solutions (source: energydigital.com).
