Together we'll plant
half a million trees

We all know that climate change can’t be solved overnight – or with a magic wand. But if we each commit to making a few small changes – together, we can take giant leaps towards a healthier planet. 

We’ve been planting trees on behalf of our Green Energy customers since 2015, with local schools, communities and volunteers through our I Dig Trees programme. But this year we’re reaching something of a milestone. By the time tree planting season is over in March, we’re aiming to have planted over half a million trees.

That’s a whole carbon-fighting forest, right there.

Frequently Asked Questions

This add-on upgrades your electricity from 33% renewables (on our standard plans) to 100% renewables.

This means that for every unit of electricity you buy, we’ll purchase a unit from a 100% renewable source (like hydro, solar, or wind). 
We also plant 5 trees a year on behalf of everyone who chooses the Green Energy add-on. It’s part of our ‘I Dig Trees’ initiative that helps reduce carbon emissions even further.

Your Green Energy add-on is continuous, so you’ll always have it unless you change your mind.

To stop the add-on, just log in to My OVO, and go to the ‘Your Profile’ page where you can hit ‘cancel’ this will be applied to your account the following month.

Depending on your statement cycle (eg. the monthly date that it’s generated), Green Energy might not show up on your statement until the month after you’ve added it. The first month it appears it’ll be backdated, so you can clearly see when your charges have started.

Well – if you’re passionate about the protecting the planet – the best part of signing up to our add-on is the knowledge that you’ll be helping the environment, and your local communities. Not only by choosing 100% renewable electricity, but by having 5 trees planted on your behalf in the UK for every year you ‘go green’. And, because our add-on is not a contract, you can add or drop it from your plan at any time in My OVO, giving you ultimate flexibility.

We’ll email you to tell you if the price is going to increase, but remember that you can always check whether you’re still ‘opted in’ through My OVO, and change this at any time. And any charges will appear on your monthly statements.

You’ll stop paying for the Green Energy add-on, as soon as you go ‘off-supply’ with us. Just let us know when you’re moving out, through My OVO.

Payments for the Green Energy add-on are taken in advance for the upcoming month, so you’ll still pay for the whole month, even if you’re leaving midway through.

You can cancel the Green Energy add-on at any time in My OVO on the my profile screen. And, if you do, your Direct Debit will be adjusted accordingly.

We get our renewable electricity from a range of sources like solar power, hydro and tidal energy. And because we’re committed to a future where the mainstream is green over half of the electricity we now supply is renewable. As our company has grown, we’ve halved our CO2 emissions. We’ve also increased the renewables in our energy mix to more than double the national average. Since 2015, none of the fuel we use is generated by burning coal.

It works almost like a trade. If you choose the Green Energy add-on, we guarantee to buy one unit from a 100% renewable energy source for every unit of electricity you buy from us.

The renewable energy we buy for you is supplied to the national grid, which in turn supplies your home.

The energy regulator, Ofgem, give out one ‘Renewable Energy Guarantee of Origin (REGO)’ certificate per megawatt hour (MWh) of renewable energy that we supply. These REGOs essentially act as proof that we’re using renewable sources, when we say we are. The same goes for GoOs 'Guarantees of Origin (GoO)' which are certificates from European participants in the Association of Issuing Bodies (

Renewable sources include wind, solar, geothermal, wave, tidal, hydro, biomass, landfill gas, sewage treatment plant gas and biogas power sources.

While the Green Energy add-on offers 100% renewable electricity, the gas portion of the dual-fuel plan uses non-renewables.

We’d love to be able to offer you renewable gas as well, but none of the available options are suitable in terms of scale and price.

We offer our add-on as a flat rate each month and give you the flexibility to opt in and out whenever you please – because, put simply, it’s much easier that way. The flat cost is not directly linked to the amount of energy you use in any given month, but accounts for the fact you’ll use less energy in summer. So even if your energy spikes in winter, the monthly amount still covers it.

Your Green Energy add-on isn’t tied to your energy contract, so you’ll continue to get the add-on until you decide to opt-out, which you can do in My OVO.

The Greener Energy plan is a fixed rate 12-month plan that gives you 100% renewable energy, the cost of which is included within the plan’s unit rates. The Green Energy add-on is different. It also gives you 100% renewable energy, but it’s an extra that can be added to any of our other plans.

We’ve now made a change that means you can only get our fixed-rate Greener Energy plan when you sign up to it via a price comparison website. After the 12-month contract ends you’ll then have to pick from one of our other plans. But you can add the Green Energy add-on to any of these and you’ll still get 100% renewable energy – just as you did on the Greener Energy plan.

We made this change because it was important to us that all our customers have the freedom to choose 100% renewable energy, no matter what plan they sign up to. This means whether you want a fixed rate or a variable energy plan, you can choose to make it green anytime you want.

Yes, you can move plans but you might need to pay exit fees if you still have time left on your contract. That’s why we recommend that you wait until it’s time to renew your plan before you consider opting into the Green Energy add-on.

Yes, you can – and we’d love it if you choose to.

1If you’re signed up to our Green Energy, we purchase renewable certificates for 100% of your electricity use from green sources such as wind, solar, geothermal, wave, tidal, hydro, biomass, landfill gas, sewage treatment plant gas and biogas. Please click here for more information.
