Key information about Octopus Energy

Octopus Energy says that everything it does is designed to make its customers’ lives better while also being as kind to the planet as possible. To help in this mission it makes four commitments:

Company history

Octopus Energy was started by Greg Jackson and Octopus Investments in 2011.

Greg’s aim was to make energy better because he felt people were paying too much and being messed around by energy suppliers too often. Octopus Investments was founded in 2000 to build companies that make a difference. Through it has a market-leading position in renewable energy. It is also a market leader in tax-efficient investment, smaller company financing and healthcare.

Octopus Energy opened its first solar generation plant in 2011. In 2017 it has 154 solar farms in the UK and 66 in France. This means it is the UK’s largest investor solar. In fact, when the sun shines, its farms generate 40% of the UK’s large scale solar – enough to power 250,000 homes, which is a city the size of Manchester.

The company also invests in:

  • green-bullet-pointWind generation
  • green-bullet-pointAnaerobic digestion plants, which use the natural breakdown of plant waste to make electricity
  • green-bullet-point“Rapid response” gas generation, which balances supply when there’s no wind and sun.


As of October 2016, it is estimated that Octopus Energy had 40,000 customers.

Warm Home Discount Scheme

Octopus Energy is not part of the Warm Home Discount Scheme. Instead, it says it has set its prices as low as possible to make its energy affordable for everyone.

The Warm Home Discount Scheme gives eligible people a £140 discount on their electricity bill between October and April. The Warm Home Discount Scheme payment doesn’t affect your annual Winter Fuel Payment or any Cold Weather Payment you might receive.

You are automatically eligible for the scheme if your energy company is a member of the scheme and you get the Guarantee Credit element of Pension Credit. People who are on a low income or get certain means-tested benefits and have their electricity from suppliers who are part of the scheme may also be eligible. If you think you may qualify, you need to apply for the payment via your electricity supplier.
