A London-headquartered energy supplier that sells electricity and gas to homes and offers smart tariffs, with a mission to make a big green dent in the universe.
Octopus Energy is a British energy supplier. It sells electricity and gas to households and also runs services around low-carbon heating. Its careers page describes work in customer support, engineering and the energy services side of the business.
Octopus describes its mission as to "make a big green dent in the universe". Its early-careers page does not list formal company values, but it says it wants people who take pride in their work, embrace change and put customers first.
Octopus is headquartered in London. Its early-careers page names apprenticeship training centres in Sheffield, Slough and Hinckley. Wikipedia reports about 11,000 employees in 2025 and 14 million customer accounts in 2026.
Octopus says it won Silver in the Best Companies to Work For awards (the page does not state the year, but the linked results refer to 2025). That is the company's own claim. It also runs the Octopus Equality Foundation, which offers free workshops and events for young people from Black and ethnic minority backgrounds.
This is one of the clearest early-career routes in the sector. The page lists school visits, short work experience placements, internships (one example lasted two months) and a two-year Level 3 Low Carbon Heating Technician apprenticeship, with pay that rises over the programme and a Heating Technician job offered on completion. Applications were described as "opening soon" with no date, so check the Octopus early-careers page. Graduate schemes were not mentioned.
