Frequently Asked Questions

What is the Octopus Solar Wallet?

It allows you to store the value of your excess solar production and use it to offset the fixed parts of your bill or even other properties.

Do they have a permanent contract?

No, all Octopus domestic tariffs are commitment-free, allowing you to switch at any time.

What is Intelligent Octopus Go?

It is a smart charging tariff that offers a very low rate of 0.068€/kWh for EV charging and can be used with any existing deal. It is compatible if you have a Wallbox or V2C charger, OR if your car is from Tesla, BMW, Mini, Audi, SEAT, ŠKODA, CUPRA, Ford, Volkswagen, Porsche, or Nissan (Ariya model). If the charger is compatible, the car brand doesn't matter, and vice-versa.
