Octopus Go on, ask us anything about our EV tariff

Octopus Go is an electricity tariff with a bonkers cheap 5p / kWh rate for four hours every night (between 12.30 and 4.30am). It was designed with EV-angelists in mind, because those sweet four hours let drivers charge up while they're asleep, and keep fuel costs around 1p per mile.

Here's the answers to every question you've ever had* about Go, all in one place.

For more info on this tariff, and others that might suit you if you drive an electric car, have a read of this blog.

For more information on all things electric cars, including smart chargers, our domestic vehicle-to-grid trial, Powerloop, company 'salary sacrifice' schemes, government grants, green taxi incentives, and a load of other exciting EV-tunities, chat to the amazing folk over at Octopus Electric Vehicles.

What are the prices involved in the Go tariff?


This electricity tariff features two unit rates:

  • A peak unit price – the price you'll be charged per unit of energy you use most of the time, between 4.30am and 12.30am. (This varies a little depending on where you are in the country, but usually hovers around 13-14p/kWh)
  • An off-peak unit price – what you'll be charged per unit of energy used between 12.30 am and 4.30am. (This is 5p/kWh, no matter where you are)

And a standing charge of 25p/ day.

What is my day rate and standing charge?


Your day rate varies a little bit depending on where you are in the UK, but generally hovers between 13-14p/kWh. Your standing charge is 25p / day.

You can get a quote for your day rate by going to www.octopus.energy/tariffs, popping your postcode in, and finding Go in our current tariffs. You’ll see your unit rate (which is the unit price of your energy for all hours outside of 12.30am and 4.30am) and your 25p daily standing charge.

Is the Go tariff fixed?


Yes. On Go, your prices are fixed for 12 months. (This means your unit rates and standing charge stay the same for the duration of your contract. Your monthly payment isn't fixed, but we'd only recommend changing it if your Direct Debit doesn't match up with your energy charges.)

45 days from the end of your contract, we'll get in contact with next year's Go prices so you can fix again and compare us to the market.

Go, like all Octopus tariffs, doesn't have any exit fees or tie-ins, so you can change tariffs or switch suppliers at any time with no penalties.

Do I need an Octopus smart meter to get on Go?


Yes. Go's innovative pricing is only possible through smart meter tech. We need to be able to link to your smart meter automatically too, which means to get on Go, you must:

a) already be supplied by Octopus

b) have a SecureTM smart meter that we can take half hourly readings from

We’ve currently paused taking new smart installation appointments as we begin a more controlled SMETS2 rollout over the next few months.

Can I switch to Octopus directly onto the Go tariff?


Go is a smart tariff. This means that you need to have a SecureTM smart meter installed before you can join the tariff. Trouble is, we're not allowed to book you an installation appointment until you've fully switched to us, which means you do need to sign up to Octopus on a standard tariff first in the interim.

All our tariffs have great, competitive rates, and you shouldn't have to wait too long for a smart meter.

There's more information about switching to Octopus for Go here. If you've got any other questions, do get in touch for further information on this, and get a quote to switch to us any time at octopus.energy.

PLEASE NOTE: We’ve currently paused taking new smart installation appointments as we begin a more controlled SMETS2 rollout over the next few months. If you don't want to wait on one of our standard tariffs in the interim, we'd recommend delaying your switch until we've started taking appointments again.

What if I don't want to get up at 1am to turn my charger on?


Fear not. We partner with Myenergi to pair Go with their acclaimed Zappi charger, which will turn on automatically when the cheap charging period starts. More information about the Zappi here.

Get in touch with Octopus Electric Vehicles' Chargin' Charlie if you want to get your hands on a Zappi.

Can I use my cheap charging period for anything other than charging my car?


Of course! During this four hour period, any electricity you use will be charged at 5p / kWh. So go nuts! If you have an immersion heater, heat your water; stick the tumble dryer on; take a 2am soak in your secret hot tub...

Don't want to get up at 1am to put the dryer on? You don't have to. There's some pretty neat stuff you can programme, too, thanks to our smart integration with Alexa.

Is there a Go gas tariff?


No. Octopus Go is an electricity tariff, created for drivers to charge their electric cars. This kind of smart tariff passes on the benefits of the UK electricity market's wholesale prices, which are highly variable through the day. Wholesale gas prices don’t really vary throughout the day, so a Go gas tariff wouldn't really be able to have that same amazing off-peak rate.

If you're a dual fuel customer, we can supply you gas too, of course. Just choose one of our standard gas tariffs, which you can get a quote for any time at www.octopus.energy/quote.

Can I be an electricity-only customer, and get my gas from another supplier?


Yes! Choose 'electricity only' at signup.

Hey! Just so you know, your device is fully charged and you're still charging it. Removing the charger will avoid degrading your battery 😊
