About Octopus Energy

The company is backed by Octopus Investments, one of the UK's fastest growing investment management companies with some £5 to £6 billion in assets under management. Octopus Investments specialises in raising capital through Venture Capital Trusts and Investment funds and invests directly in companies and assets, with a particular focus on smaller companies, healthcare, property finance and, of course, energy.

In the energy sector Octopus Investments is the UK's largest investor in solar farms, and has also invested significantly in wind generation, in anaerobic digestion plants, and in "rapid response" gas generation (gas generation plants used to balance the energy supply side when there is no wind and sun).

Octopus Energy entered the market with the belief that the energy business they wanted to create would be better for customers (simpler, more transparent and honest), better for the planet and better value.

They are attacking these goals by;

• - Doing away with lock in contracts
• - Offering a true green tariff that combines 100% renewable electricity with full carbon offset on the gas side.
• - Focusing on the use of technology to create a leaner, lower cost and more responsive business.

Octupus Energy is of course not the first energy supplier to come to market with these ambitions. Co-operative Energy made a lot of similar promises about "always offering fair prices" and being "committed to a sustainable world" and look where Co-operative energy ended up.

However, having met the Company and seen their operations, coupled with the management team and financial backing that they have put in place indicates that this is one of the new energy suppliers that could actually make a difference.
