Octopus Energy

Company Overview

Octopus Energy, a subsidiary of Octopus Capital Limited, part of the Octopus Group

London, United Kingdom

2015

Approximately 3,000 employees globally (source: linkedin.com). No public revenue figures for 2023 or later are disclosed, but it manages £7 billion in renewable assets and £6 billion in generation capacity powering four million homes (source: octopusenergy.com).

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). While specific benefits such as salaries or health plans are not publicly detailed, the company is known for its commitment to low-cost service and scalable tech career growth opportunities across its international operations.

As Octopus has grown, so too has the complexity, variation and scale of our cost base.

As such, we're looking for a curious, detail-driven part or fully qualified accountant with data skills to help us truly understand, validate, and control our cost base.

This role sits right at the intersection of finance, data, and the wider business; giving you real ownership over how costs flow through the accounts and how they impact our reporting. You'll work closely with our Finance and Gross Margin teams to build and maintain a robust cost accruals process, partner with other teams across the business to understand how costs arise in the real world, and turn that insight into scalable, automated processes. If you enjoy getting under the hood of complex data, improving controls, and building new processes and systems, this is a role where you can have a big impact.

This is a fantastic opportunity to work at the intersection of finance and data in an award winning team for a high growth business that is at the forefront of the net zero transition.

What You'll Do

  • Become a subject matter expert in our cost base in the UK, including how these costs are validated and settled. Partner with teams across the business (e.g. Operations, Accounts payable and many others!) to understand how costs work and build this understanding into our validation and accrual process;
  • Work with Finance and Gross Margin teams to build a robust cost accrual model in order to reconcile and validate our cost base reporting, and identify, report and analyse any associated risks and opportunities on monthly basis;
  • Build pipelines to automate the entry of invoices into Netsuite from external systems, and partner with teams across the business to build a process for invoice validation;
  • Work with our Global Retail teams to roll out cost validation solutions globally

What You'll Need

  • Fully or part qualified and actively studying towards an accounting qualification (CIMA, ACCA, ACA or equivalent);
  • Strong SQL and Excel knowledge;
  • Experience working in management accounts and an understanding of month end accounting, accruals and finance systems (e.g. Netsuite);
  • Highly data literate and numerate, with great attention to detail - you are able to make sense of lots of data, discover trends and patterns;
  • Great communicator - can clearly articulate complex technical information to non technical colleagues.

Nice to have but not essential

  • Experience working in the energy industry, bonus if you have worked with settlement information before
  • Ability to code in Python
  • Experience with building dashboards (eg. in Databricks or Streamlit);
  • Experience in modern data development, using modelling tools such as dbt, Lakehouses such as Databricks, and collaborative codebases such as git.

We aren't necessarily looking for someone who is "10-out-of-10" in all these areas, but rather someone who has good experience in most of them, combined with a flexible and enthusiastic approach.

Why else you'll love it here

  • Wondering what the salary for this role is? Just ask us! On a call with one of our recruiters it's something we always cover as we genuinely want to match your experience with the correct salary. The reason why we don't advertise is because we honestly have a degree of flexibility and would never want salary to be a reason why someone doesn't apply to Octopus - what's more important to us is finding the right octofit!
