Octopus EnergyESG & Sustainability Jobs

UK energy supplier offering renewable electricity, gas, heat pumps, solar, batteries, and EV tariffs for homes and businesses.

Octopus Energy is a UK retail energy supplier serving homes and businesses with electricity and gas, alongside products including heat pumps, solar panels and batteries, and electric vehicle tariffs and chargers. It sells directly to customers without intermediaries and operates its own technology platform, Kraken, which underpins its billing and smart tariff capabilities.

Why it matters

Octopus is one of the larger forces pushing household energy consumption toward renewables in the UK. Its smart tariffs - such as Agile Octopus - price electricity by the half-hour, rewarding customers who shift demand to times when wind and solar generation is high and grid carbon intensity is low. By bundling heat pumps, home batteries, and EV charging into its tariff ecosystem, it creates a practical pathway for households to cut fossil fuel use across heating and transport, not just power.

Octopus has grown to become the UK's largest domestic energy supplier by customer numbers and has expanded its technology and retail model internationally. It also invests directly in renewable generation assets, giving it a stake in the supply chain it sells from.
