What Intelligent Octopus Go is
Intelligent Octopus Go is Octopus's flagship EV tariff: a cheap, published overnight rate, plus smart scheduling that decides exactly when inside the overnight window your car actually charges, based on your car's own state of charge, the time you say you need it ready, and grid conditions. The published rate applies within a roughly six-hour overnight window (23:30 to 05:30), rather than to the whole day.
It is built primarily around EV charging, not solar export or battery arbitrage; a household without a compatible EV or charger does not gain the tariff's headline benefit. Octopus also sells a compatible smart charger from around £949 installed for customers who don't already have one, per its own page.
The rate, as checked today
8p/kWh off-peak, from 1 October 2026
8p/kWh from 1 October 2026; 8.4p/kWh until then, per Octopus's own page checked today. The day rate for charging outside the smart window is not stated as a single national figure on the fetched page.

Who can get it
- A compatible EV or smart charger - Octopus's own page notes compatibility varies and changes regularly as vehicle and charger specs update
- Alternatively, a compatible smart charger purchased from Octopus, from around £949 including standard installation, per Octopus's own page
- A UK smart meter - the tariff is described as reliant on the smart meter network
Who it suits: A household with an EV, or planning one, that can charge overnight and wants Octopus's own scheduling to handle exactly when within that window, rather than a flat overnight rate with no smart element.
Does this pair with a Clearline installation?
Yes. Intelligent Octopus Go is an EV tariff with no condition tied to who installed a home's solar or battery; eligibility depends on having a compatible EV or charger and a smart meter.
Every installation is carried out by our teams, who hold:
How Intelligent Go pairs with each route
Solar
No direct interaction: Go prices import for EV charging, not solar export. A solar household still needs a separate export tariff for what the panels send back to the grid.
Battery
Go is built around EV charging specifically rather than whole-home battery dispatch; a household wanting a tariff that also manages a home battery's charge and discharge should compare Octopus Flux or Intelligent Octopus Flux instead. A compatible home battery may still be able to draw from the grid inside Go's cheap window depending on its own setup, which is worth confirming on the design call rather than assuming.
EV charging
The core use case. The published overnight rate plus smart scheduling is what the tariff is built for.
Heat pump
No direct interaction; a heat pump household should compare Octopus Cosy, which is built around a heating schedule rather than EV charging.
Charging 40 kWh, on and off the smart window
Using the confirmed rate from today's check (8p/kWh from 1 October 2026) against the current Ofgem price cap unit rate (26.32p/kWh, Oct-Dec 2026), here is what a typical overnight charge costs on each.
| Scenario | Rate | Cost, 40 kWh | Cost per mile |
|---|---|---|---|
In the Intelligent Octopus Go window | 8p/kWh | £3 | 2.3p |
At the current price cap unit rate | 26.32p/kWh | £11 | 7.5p |
Saving on this one charge: £7. Illustrative for a roughly 40 kWh charge, broadly a mid-size EV's usable battery. Your own car's battery size and typical charge amount will differ; we work through your actual numbers on the design call.

Octopus Energy Intelligent Go questions, answered
What is the Intelligent Octopus Go off-peak rate?
8p/kWh from 1 October 2026 (8.4p/kWh until then), checked directly against Octopus's own page today, within a smart-scheduled window of roughly 23:30 to 05:30.
Do I need a specific EV or charger for Intelligent Octopus Go?
A compatible EV or smart charger, per Octopus's own eligibility page, which notes compatibility changes regularly. Octopus also sells its own compatible smart charger from around £949 installed for customers who need one.
How much cheaper is Intelligent Octopus Go than the standard rate?
Comparing the confirmed 8p/kWh off-peak rate to the current Ofgem price cap unit rate of 26.32p/kWh (Oct-Dec 2026), that is roughly 69% cheaper per unit, per the comparison Octopus's own page draws.
Does Intelligent Octopus Go work for a home battery, not just an EV?
It is built and marketed around EV charging specifically. Whether a compatible home battery can also draw from the grid within Go's cheap window depends on your own battery and inverter setup; confirm it directly rather than assuming it behaves like Octopus Flux, which is a different, battery-focused tariff.
Can a Clearline installation qualify for Intelligent Octopus Go?
Yes. The tariff has no condition tied to who installed a home's solar or battery; eligibility is about having a compatible EV or charger and a smart meter.
Is Intelligent Octopus Go the same rate all night?
The published 8p/kWh (8.4p until 1 October 2026) applies within a roughly six-hour smart-scheduled window between about 23:30 and 05:30; Octopus's own scheduling decides exactly when inside that window your car actually draws power, based on when you need it ready.
