What unit rates and standing charge will I pay on the Go tariff?


The Go 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 04:30 and 00:30. This rate varies depending where you are in the UK.
  • An off-peak unit price – what you'll be charged per unit of energy used between 00:30 and 04.30. This is 9p / kWh, no matter where you are.

There's also a standing charge, which again varies depending where you live in the UK.

You can check what unit rates and standing charge apply in your area here:

Do I need a 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 have a SMETS2 or Secure SMETS1 smart meter that we can take half hourly readings from.

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

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


Fear not. We have partnerships with a few different smart charging trailblazers, like Ohme, the UK's first smart home charging cable, which can automatically turn charge mode on when the 'off-peak' charging period kicks in.

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 9p / kWh.

You can even automate stuff to come on using smart plugs and neat, simple to set up integrations with Alexa and IFTTT – check out some smart home hacks from our brilliant customers.

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

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


Yes! Choose 'electricity only' at signup.

Can I still export energy on Octopus Go?


We’ve created a new tariff called Outgoing Fixed Lite, which gives Octopus Go customers export rates of 8p/kWh. You can sign up to the tariff here.

Are other Octopus tariffs available?

Can I use Octopus Go in more than one property?


No, the tariff is linked to a single property.

Is Go suitable for multiple car households?


Yes. You can use the Go tariff to charge more than one car, but can only benefit from the off peak rate within the 4 hour window.

What happens to the off-peak period during daylight savings?


Number one and most important: no matter what your IHD says, your off-peak period stays between 00:30 and 04:30.

Why is my IHD saying something different?


This SHOULD be straightforward – but some customers have noticed that their in-home display (part of the smart meter infrastructure) shows the cheap rate kicking in at 01:30 following a clock change.

On your bills, it'll say the cheap period starts at 00:30. This is obviously pretty confusing, and makes it hard to know which is correct. The challenge is that the IHD is not “determining” anything. It’s just displaying some information, and in the journey from Octopus to DCC (the government’s data company, which handles smart meter data), to TMA (a company who connect Octopus’s smart meters to DCC), to the comms hub (a regulated device which carries the signal to the smart meter), to the smart meter itself, to the IHD (which sits on a different network, established by your electricity meter) there are many steps – each of which may pass the time signal as it is, or may “helpfully” correct it from GMT to BST etc.

There are quite a few different ways to get a message to the IHD and some are simpler than others, but allow less functionality – so we’re trying to use the smartest way... but it’s also the most complex.
