Who offers the greenest energy?
Many choose their energy provider based on how much they care about the planet, but what sets Good Energy and Octopus apart? Now, we’ll compare them when it comes to green energy.
Octopus manages renewable energy assets valued at £3.4 billion, sufficient to supply power to around 2 million households in the UK. The company encourages customers to install solar power systems at home as part of its sustainability efforts.
From 2018 to 2021, Octopus effectively neutralised 708,700 tonnes of CO2 emissions. Their commitment to eco-friendly innovation includes a £10 million investment in the UK’s only research and development centre focused on low-carbon heating solutions. All of Octopus’s electricity tariffs are 100% renewable, highlighting their position as one of Europe’s leading renewable energy investors.
Ecotricity produces 100% green electricity from wind and solar sources, generating about 12% themselves and acquiring the rest from certified green sources. They also turn customer bills into new renewable energy projects, such as wind and solar parks across the UK, thereby increasing the nation’s renewable capacity.
Since 1996, Ecotricity has pioneered wind energy, building 24 wind parks with 74 windmills that power over 56,000 homes and save over 31,000 tonnes of CO2 annually. They also operate three Sun parks, with others in the planning stage.

Who has the better app?
Many energy customers choose to manage their accounts via their phones, so when it comes to account management, a supplier’s app is very important.
Ecotricity have an app on the App Store but it doesn’t appear to have any reviews or ratings yet.

Octopus Energy’s app scores a very high 4.8/5 on the App Store and similarly highly on the Google Play store. Customers say they use the app to check usage, submit meter readings and pay their bills easily. The app also offers detailed charts and data on your energy usage, even in near real-time.

Who is the better supplier?
Octopus Energy are probably the better supplier for you if you are focused on price and are keen to have a well-developed app to manage your account. They also have better customer reviews.
On the other hand, if greener tariffs and customer service are important to you, then Ecotricity may be the better option.
This is very helpful, but omits to comment on tariffs to encourage purchase of solar panels by individua households. This seems an obvious contribution to increasing carbon free electricity and after several years of asking ecotricity if and when they will pay toward some of the electricity I return to the grid every year, as I don’t wish to purchase a battery, I am fobbed off with some comment about it being planned – but it clearly isn’t. Octopus are the clear winners here as they even pay for electricity returned by people who are not their customers.
I am disappointed but will now probably change to Octopus and lodge a complaining with Ecotricity for the many misleading responses I have been sent…. and lack of acknowledgement of my contribution to the grid….
Hello Rob, thank you so much for publishing this, that is priceless and must have taken a lot of your time.
My reason for favouring Ecotricity is as you say
their commitment to ethical practices and reinvesting profits into renewable projects, Ecotricity is at the forefront of the green energy movement, inspiring global change towards cleaner, sustainable energy solutions.
Also happy to pay a bit more for them doing the right thing and supporting a smaller business.
Whereas Octopus pay out all profits to shareholders which is the same as all the water companies do and it’s obvious where we ended up. They are massive and there is a lot of pressure behind to grow quicker and e.g install as many heatpumps as possible in one day. You can also see it on the amount of advertising they though.
Hence Ecotricity is a winner for me at the moment and I’ll see how I go with them.
