Switch today for a greener future

Green Future tariffs are the greenest we have available to help you manage your carbon footprint today. Sign up and as you power your home, you’ll also be supporting a variety of exciting initiatives that help protect our planet.

On a Green Future tariff, we’ll match your home energy use with fully-certified, renewable sources. Put simply, most of your CO2 emissions from your home energy use will be balanced with renewable energy and carbon offsetting, getting your home closer to carbon neutral.

And that’s just the beginning. Because with a Green Future tariff, you’ll support carbon-cutting projects at home and abroad. Right now, that means helping UK woodlands through tree-growing projects and protecting an entire hectare 1 of precious Amazonian rainforest. 

Traceable, fully-certified green energy

We’ll match 100% of the electricity you use with verified renewable sources, such as wind and solar

We’ll match 10% of the gas you use with renewable sources certified by the Green Gas Certification Scheme (GGCS).

We’ll offset 90% of the CO2 footprint for your gas use on this tariff by supporting traceable carbon-cutting projects in developing countries.

We’ll also support the growth of up to 10 UK woodland trees when your property has both fuels on this tariff.

Power your home, protect our planet

Green energy

Biomethane (also known as green gas or biogas) is created from leftover food or farm waste. It’s then fed into the national gas grid and piped to homes across the UK. Unlike normal gas which is made from fossil-fuels, burning biomethane is virtually carbon neutral, so it’s better for the environment.

Renewable energy technologies, such as wind and solar, have a much lower environmental impact and can help us cut carbon emissions and slow down global warming.

Rainforest projects

By supporting the Ecomapua rainforest project, you’ll help to protect an entire hectare 1 of Amazonian rainforest – that’s the same size as one and a half football pitches.

You’ll also support the Marajo Island community by helping to provide work, economic growth, and the ability to grow sustainable acai berries for food and biofuel. Thanks to the project, the native species of wildlife that live there are also under protection.

UK woodland projects

For each year of your tariff with both fuels, you’ll support the growth of up to 10 trees in the UK per household, helping the natural wildlife and increasing soil stability.

During their lifetime, 10 trees can remove up to 10 tonnes of CO2 from the air – that’s the same as taking five average cars off the road for an entire year. Trees planted will include a range of native broadleaf species, including birch, oak and alder.

The power of trees - nature’s carbon storage expert

Tree-growing projects in the UK and Amazonian rainforest initiatives are positive steps toward a healthier planet. That’s because trees absorb CO2 and release oxygen as they grow. Did you know that a single hectare of temperate forest absorbs as much as seven tonnes of CO2 each year 2 ? And with CO2 making up around three-quarters of greenhouse gas emissions 3 , it’s easy to see why projects like these need our continuing support.

Traceable sources

On a Green Future tariff, we make sure the emission-reduction projects you support are proven to make a positive difference.

With the help of our partner, ClimateCare, we buy independently-verified carbon credits from qualified and registered projects. Our current rainforest protection project is verified by the Verified Carbon Standard. And our UK woodland projects are verified by the Woodland Carbon Code.

So you can be sure that as we welcome projects in the future, they’ll be worthwhile and deserving of your support.

Inspiring change. For just a little extra

Green Future tariffs power your home while protecting the environment, for a few pounds extra per month compared to our fixed-rate tariffs. You’ll lend your support to great projects led by people who care and want to create change, for just £3 more each month. And there are other great eco-friendly initiatives on the way, too. Because that’s what Green Future Tariffs are about – working together to make a difference to tomorrow.

Frequently asked questions

What are renewable energy certificates?

We’ll match 100% of the electricity you use with our Green Future tariffs by buying the same amount of electricity from renewable generators in the UK, through agreements called Power Purchase Agreements. This means that for the electricity you use, the same amount of electricity from renewable sources, such as wind and solar, will be fed into the network. We evidence this by buying also Renewable Energy Guarantees of Origin certificates (REGOs) with the renewable electricity we purchase.

What is green gas and why are green gas certificates important?

We’ll match 10% of the gas you use on this tariff by buying gas from renewable sources. This means that for 10% of the gas you use, the same amount of gas from renewable sources will be fed into the national gas network. We evidence this by buying Renewable Gas Guarantees of Origin (RGGO) certificates from the Green Gas Certification Scheme (GGCS).

Green gas is made from biomethane and comes from renewable sources, such as food or farm waste. The organic matter is broken down in a process called anaerobic digestion. The green gas it creates is then fed into the gas grid and piped to homes across the UK. Unlike gas derived from fossil fuels, burning biomethane is carbon neutral – in other words, the process releases the same amount of carbon dioxide that the organic matter used when it was growing.

Each unit of green gas added to the national grid displaces a unit of conventional gas. The GGCS tracks each unit of green gas, and for each kilowatt hour added to the grid, one RGGO certificate is issued. 

What does carbon offsetting mean?

Carbon offsetting helps you reduce your environmental impact by supporting projects that reduce greenhouse gas emissions. This means that an amount of the carbon dioxide emissions you generate as you use energy at home is compensated through projects that reduce emissions.

With our carbon-offsetting partner, ClimateCare, we’ll offset your gas carbon footprint for 90% of the gas you use on this tariff by supporting selected and traceable emission-cutting projects in developing countries.  

ClimateCare evidence this through Verified Emission Reduction Certificates (VERs) from projects verified by the Verified Carbon Standard. Each certificate is equivalent to one tonne of carbon dioxide. For more information about the Verified Carbon Standard go to www.verra.org/.

We’ll also support the growth of up to 10 trees a year per household in the UK if your property has both fuels on a Green Future tariff. With the help of ClimateCare, we evidence the number of trees you’ll be supporting by buying either pending issuance units (PIUs) or woodland carbon units (WCUs) from UK woodland projects, verified by the Woodland Carbon Code. We buy PIUs or WCUs in addition to carbon offsetting 90% of the gas you use by buying VER certificates from the Verified Carbon Standard. For more information about the Woodland Carbon Code go to www.woodlandcarboncode.org.uk/.

ClimateCare ensure that all the projects you’re supporting on our Green Future tariffs meet only the highest-quality standards. For more information about ClimateCare, go to https://climatecare.org.

Depending on the popularity of the tariff or for other reasons beyond our reasonable control, we might purchase carbon credits from other emission-reduction projects not advertised at launch. If so, we’ll always do our best to ensure that the carbon credits ClimateCare buy on our behalf are of a comparable quality and standard. We’ll always ensure that we purchase enough carbon credits to offset the carbon footprint created from 90% of the gas you use on this tariff, and enough carbon credits to support the growth of five trees per fuel per year.  

If you change your mind?

Should you decide it’s not the right tariff for you and you want to cancel your contract, you won’t have to pay an exit fee within 14 days of signing up.

An exit fee may apply if you decide to switch to another supplier before the end date of your fixed tariff, but not during the switching window, which starts 49 days before the tariff ends. If you decide to change to one of our other tariffs at any time, there are no exit fees. Please see T&Cs for full details including exit fees for each tariff.

Additional information
