Octopus Supergreen Tariff

Octopus Super Green Tariff This fixed tariff is the very greenest you can be with Octopus with a fully carbon neutral energy plan! All Octopus electricity tariffs are 100% renewable as standard - (read about where our energy comes from here), plus, on Super Green, any gas you use is fully carbon offset through our partner Renewable World who we work with to choose Gold Standard Verified projects - learn more here. Carbon emission data is calculated using BEIS 2020 emission factors. Supergreen Octopus has no exit fees.

We believe green should be the easy choice, so we offer Super Green at only £1 extra a month to our fixed tariff costs. That’s less than the cost of a coffee (or 4 Freddo’s).

You do not have to get a smart meter for the Super Green tariff, however, smart meters are the cornerstone of a smarter, greener energy system. They're more convenient (no more meter readings), they help you keep track of your energy usage. Register your interest here: Smart Meters

On the Octopus Super Green tariff, in addition to the 100% renewable electricity available with our standard plans (fuel mix found here), we also provide 100% carbon-neutral gas (100% offset - read why we don’t use green gas here). This involves offsetting the carbon emissions involved in the production of your gas. The renewable electricity we sell is backed by renewable certificates (Renewable Energy Guarantee of Origin certificates (REGOs)). See here for details on Renewable Energy Guarantee of Origin certificates and how these work. We offset the remaining emissions by supporting Renewable World’s Gold Standard certified carbon reduction projects. See here for more information on how we support tech poor communities with our offsetting programmes.

Everyone has a carbon footprint, measured in terms of tonnes of carbon emitted per year. In order to neutralise the carbon emissions we are responsible for, such as our energy usage, we can support schemes that take carbon out of the atmosphere or stop them entering it in the first place. By working with carbon reduction projects we can buy carbon offset credits (which each equal 1 tonne of carbon) in order to balance out the negative emissions of your gas usage. Offsetting your gas usage in addition to your 100% renewable electricity means your home energy usage becomes ‘carbon neutral’.

Renewable World are a charity that brings low-carbon technologies to areas with limited access to safe, reliable energy. These clean energy hubs bring whole new income streams into the communities and return agency to local people and businesses who’ve been constrained by unreliable, high-polluting energy sources.

Biomethane, or biogas, is offered by some of our fellow green suppliers. Biogas is made from organic matter such as animal and food waste and can be added to the gas system (it currently accounts for around 4% in the UK). However, apart from being very expensive for customers, large scale production is not yet possible and we do not believe it is the best route longer term. We want to ditch gas for good. So, instead of investing in biogas, our approach is to invest in clean electricity initiatives to build a world where we do not need gas at all.

As with any Octopus tariff, you can cancel anytime.

Also known as ‘green energy’ renewable energy is energy that is collected from resources that naturally replenish themselves, such as sunlight, wind, rivers and geothermal heat. This is in contrast to non-renewable sources such as coal and oil which do not replenish within a human lifetime and also pollute the environment. At Octopus we use renewable energy sources primarily from wind, solar and hydro (water) sources to power our 100% green electricity. As over 85% of the UK still use gas in their homes, we also provide our Super Green tariff where customers can offset the carbon emissions produced by the gas part of their home energy usage.
