You'll need to:

Be an Octopus Energy customer

If you're not with us yet, sign up below and you'll join us on one of our standard tariffs initially while we connect all the dots behind the scenes.
Have an eligible electric car and a home EV charger

Our Octopus Go Green Tariff is designed exclusively for Volkwagen, Audi, SEAT, Skoda or Cupra EV drivers who either own or long-term lease a battery electric vehicle or a plug-in hybrid vehicle that they'll be charging at home, so you need an electric vehicle from one of these brands to join. If you're in the process of getting one and have an order number to hand, we can switch you so that you're ready to charge once your vehicle arrives.
Have a smart meter we can connect to

We can connect to second generation (SMETS2) meters, and some types of first generation (SMETS1) smart meters. How do I know what type I have?

If you have a compatible smart meter already, you're all set. If you don't have a smart meter yet, or you have a different type of smart meter, you can still start the switch to Octopus Go Green below, but you'll need to stay on one of our standard tariffs while we get you Octopus Go Green-ready.

In some cases, this could take weeks, or might not be possible at all if your home isn't suitable for a smart meter — but you're able to switch away any time with no exit fees. Read more on this.
Before signing up, please read this quick guide covering:
- How to know whether you're eligible for a smart meter
- What to do if you have the wrong type of meter
- Why we can't always install your meter right away
- How long it takes to get your smart meter connected
- Our Covid-safe installations policy
Hang tight while we connect to your smart meter

It generally takes us around 14 days to connect to a smart meter so we can read it remotely – whether it's one we've just installed, or one we're taking over after you switch to us.

Accept our Terms & Conditions via email

Once we're connected and getting half–hourly readings from your smart meter, we'll send you an email asking you to accept the Terms & Conditions of Octopus Go Green to complete your switch.

Once you've confirmed via email,
You're good to go!

Your tariff will change automatically to Octopus Go Green. You should see the change straight away on your online account.

Read our Go Green FAQs

Octopus Go Green is a product of our labs, available now to customers through our beta programme.

You'll need a SMETS2 smart meter, or a “Secure” branded SMETS1 meter, that we can receive half-hourly consumption data from.

Don't have a suitable smart meter?

Start your switch below to register your interest for a smart meter. The smart meter installation comes at no extra cost.

Once you've registered your interest, our team will be in contact when we have an appointment in your area.

Octopus Go Green is a beta product. Some things may not work the first time, and installations and processes may take longer than we'd like. Third party tech like In-home Displays won't always work, and on occasion data issues with smart meters can take significant time to fix or prevent things from working at all.

If you're cool with this, and you'd still like to work with us to make world-changing energy tariffs a reality, check this box so we know you're on board. You will always be able to switch to one of our fairly priced standard tariffs at any time.

Due to continued market volatility and the beta nature of this smart tariff we may need to restrict daily sign ups. You're still free to sign up below, and we'll let you know if this ever affects you.

Octopus Go Green is a cutting edge innovation created by Octopus's unique technology. Unlike products available from other companies, it relies on a smart meter system (which as our Founder Greg explains here, is not always fully reliable). Some customers have experienced delays. However, of the thousands of customers on these smart tariffs, the vast majority are now experiencing smooth service.

Octopus Go Green is backed by electricity we purchase directly from renewable generators. We work with more than 190 green energy producers to power the homes that sign up to our Octopus Go Green tariff.
