Terms and conditions

*New customers to Octopus Energy who purchase an electric vehicle and who set up an account for gas and/or electricity who sign up via the referral link provided on this page will be eligible for free miles in the form of £45 credit per fuel type on their energy account. To receive £90 credit, customers must switch both fuels to Octopus Energy. If only one account is switched, the customer will receive £45 credit. The credit shall be applied once the account is on supply and the first direct debit payment has been taken. If you qualify for more than one marketing incentive, Octopus reserves the right to give you just one incentive.

**Free miles in the form of a £90 credit: For Example the ID.3 Life 58kWh 204PS ‘Pro Performance’, at Octopus' Go tariff off-peak rate (7.5 p/kWh), £90 credit is equivalent to up to 5,000 miles. This is based on a usable battery capacity of 58 kWh and WLTP range of 260 miles giving an efficiency average of 0.22 kWh/mile. Tariff rates are correct as of 01st April 2022. Additional savings of up to £120: Savings calculated by comparing a typical EV owning household’s consumption on Go Green rates vs. Flexible Octopus rates. Total predicted consumption equates to 4,861kWh (based on a medium household’s consumption as defined by Ofgem and an annual EV mileage of 7,400 miles), and assumes that 95% of EV charging occurs in the cheap charge window. Rates are correct as of 01st April 2022.

To benefit from the Octopus Go Green tariff, the customer must have a SMETS2 smart meter or a SecureTM branded SMETS1 meter that they have agreed to let Octopus receive half-hourly consumption data from. There are some instances where a smart meter installation is not possible, for example, remote areas with poor mobile signal. Where smart meter installation is not possible, customers can sign up to an Octopus standard tariff and still receive the £45 credit per fuel type.

For existing Octopus customers who joined us directly are still eligible for this offer. However, if you joined us via our Refer a Friend scheme or through one of our partners, and have already received a joining reward, unfortunately, you're not eligible for a free miles reward. If you're a gas and electricity customer and haven't received a joining reward from us previously, you'll receive a £90 credit. If you're only with us for one fuel type, you'll receive £45 credit. Drop us an email at existingevoffer@octoenergy.com to take the offer.

^ Four hours of 7.5p/kWh super off-peak electricity: Rates are subject to change. Off-peak rates of 7.5p/kWh electricity are correct as of 01st April 2022.

*** Fuel costs of approximately 2.5p/mile: Based on ID.3 1st Edition with ‘Pro’ with a usable battery capacity of 58kWh and a driving range of 260 miles, fully charged during the cheap charging window.
