Octopus Agile is not a traditional EV tariff. Rather than offering a fixed cheap overnight rate, it prices electricity every 30 minutes based on the wholesale market — meaning rates change throughout the day and can drop below zero when there is surplus renewable energy on the grid.
The EVs that benefit most from Agile are not defined by brand or charger compatibility. They are defined by usage patterns. Agile suits drivers who are frequently home, flexible about when they charge, and willing to use scheduling tools or automation to capture the cheapest half-hour slots.
What Is Octopus Agile?
Octopus Agile is a half-hourly time-of-use electricity tariff. Rates are published by 4pm each day for the following 24 hours, reflecting wholesale electricity prices. When demand on the grid is high, rates rise. When there is excess renewable generation — particularly wind overnight — rates fall sharply, sometimes dropping below 0p/kWh.
At negative rates, Octopus pays you for every unit of electricity you consume. This can occur for stretches of hours during high-wind nights, offering EV drivers the chance to charge at no cost or even receive a small payment for doing so.
The unit price is capped at £1 per kWh. The daily standing charge is approximately 61.19p.
Because rates are variable, Agile does not have a simple “off-peak rate” comparison in the way that Octopus Intelligent Go (8p/kWh) or E.ON Next Drive Smart (8p/kWh) do. Your average charging cost depends on how actively you manage when you plug in.
Who Is Octopus Agile Best For?
Drivers who are home during the day or work flexible hours
Agile rates vary throughout the day, not just overnight. Someone who is home between midday and 3pm on a sunny, low-demand Tuesday may find rates well below 5p/kWh — comparable to or cheaper than a fixed overnight rate. High-mileage drivers who can charge opportunistically at the cheapest moments across the day gain the most from Agile’s flexibility.
Drivers with home batteries
A home battery storage system (such as Tesla Powerwall, Givenergy, or similar) works extremely well with Octopus Agile. The battery charges during the cheapest half-hour slots — including negative-rate periods — and then powers the home and EV during expensive peak periods. This requires smart home integration or automation (see below).
Solar panel owners
Combining Octopus Agile with solar panels means your panels cover daytime consumption at zero marginal cost, while Agile captures cheap grid energy at night and on cloudy days. For households that export surplus solar, Octopus offers separate export tariffs alongside Agile. See our guide to how Octopus Flux works for solar and EV owners for a tariff specifically designed for solar + battery households.
Drivers willing to use smart home automation
Octopus provides a public API for Agile rate data, meaning tools like Home Assistant, IFTTT, Octopus Watch, and similar automation platforms can automatically turn on EV chargers, appliances, and batteries when rates fall below a threshold you set. For tech-comfortable drivers, this can extract significant savings without daily manual effort.
Which EVs Get the Most From Octopus Agile?
Any EV with a flexible charging schedule
Because Agile does not offer a fixed window, the EVs that benefit most are those whose drivers can flex when charging begins. If you drive a set commute every weekday and charge overnight regardless, you will capture some savings — but you will not be as well positioned as a driver who can shift charging to a 1pm lull or a negative-rate period at 3am.
Tesla Model 3 and Model Y
Tesla’s onboard scheduling and the Tesla app’s scheduled charging feature let you set both a start time and a departure time. Combined with an automation tool reading Octopus Agile’s published half-hourly prices, you can configure the Tesla to begin charging only when rates drop below a threshold. Tesla’s direct integration with the Octopus app also makes it easy to set preferences if you want to combine this with Octopus Intelligent Go as a comparison point.
Kia EV6, EV9, and Niro EV
Kia’s Connect app supports remote charging scheduling, allowing you to delay charge starts. Coupled with Agile rate monitoring, you can set charges to begin when rates drop. Kia vehicles are not on the Octopus Intelligent Go direct integration list, making Agile (or a smart charger on Intelligent Go) the best path to rate optimisation.
Hyundai IONIQ 5 and IONIQ 6
Hyundai’s Bluelink app supports departure time scheduling and remote charge start/stop. The IONIQ range is not natively integrated into Octopus Intelligent Go, so Agile with charger automation or manual scheduling is a strong alternative.
MG ZS EV, MG4, and MG5
MG’s iSmart app supports charging timers, making it straightforward to schedule charging to Agile’s cheapest windows. MG vehicles are not on the Octopus Intelligent Go compatibility list, making Agile a competitive option.
Volkswagen, Audi, Skoda, SEAT, Cupra (via Zappi)
VW Group vehicles have direct Octopus Intelligent Go integration, so most owners in this group will prefer Intelligent Go for its automated scheduling. However, drivers with a Zappi charger and solar panels may prefer Agile’s flexibility, which allows the Zappi to also capture daytime cheap grid energy during low-rate periods, combined with solar generation.
Agile with a Smart Charger
A smart charger that responds to Octopus Agile price signals automates the rate-chasing process.
Zappi (myenergi) works well with Agile. Its open API allows integration with Home Assistant and similar platforms. Set a threshold rate in your automation, and the Zappi starts charging whenever Agile drops below it.
Ohme Home Pro can be set up to respond to Octopus Agile prices, scheduling charge sessions around cheapest-rate periods. The Ohme app shows upcoming rate forecasts to help you plan.
Octopus Agile vs Octopus Intelligent Go: Which Is Better for EV Charging?
For most EV owners who primarily charge overnight and want a simple, predictable cost, Octopus Intelligent Go is the better choice. The fixed 8p/kWh rate from 11:30pm to 5:30am is guaranteed and requires no active rate-monitoring. The automated scheduling feature means you never think about when charging starts.
Agile is better for drivers who have the flexibility, tools, or inclination to shift consumption dynamically. It can deliver lower average rates than any fixed overnight tariff during periods of high renewable generation — but it requires more engagement.

How to Get the Most From Octopus Agile as an EV Driver
-
Check tomorrow’s rates every evening. Rates are published by 4pm. The Octopus app shows a graph of the upcoming 24-hour pricing. If rates between midnight and 4am are forecast at 5p/kWh or lower, charging then delivers excellent value.
-
Set your charge timer around the cheapest slots. Most EVs allow you to set a charge start time via the car’s infotainment or connected app. Set it for the lowest-rate window identified in the Octopus app.
-
Use automation for hands-off savings. Tools like Home Assistant with the Octopus Agile integration, or Octopus Watch, can automatically start and stop charging based on price thresholds. You set the threshold (e.g. below 10p/kWh) and the system handles the rest.
-
Exploit negative rates when they occur. During high-wind overnight periods, rates can go below 0p/kWh. If you can start a charge session at these times (manually or via automation), you can charge your EV at no cost.
-
Set a minimum charge level. Whatever rate optimisation you use, always set a minimum charge level in your car’s app so you are never left short. A 20% minimum ensures you can drive to work even if the cheapest slots were not available overnight.
Frequently Asked Questions
Is Octopus Agile good for EV charging? Yes, particularly for flexible drivers. When renewable generation is high, Agile rates can drop to 5p/kWh or lower — below the fixed rates on Octopus Intelligent Go (8p/kWh) or E.ON Next Drive Smart (8p/kWh). However, when demand is high, rates rise well above standard tariff levels. The average annual cost depends on how actively you manage charging. Drivers with smart home automation can consistently beat fixed overnight tariffs.
Does Octopus Agile have an off-peak rate? Not in the traditional sense. Agile prices are set every 30 minutes based on wholesale costs, so the “cheap” periods vary daily. Overnight hours typically have lower rates because grid demand is lower, but there is no guaranteed fixed window as with Intelligent Go or E.ON Next Drive.
Which charger works best with Octopus Agile? The Zappi by myenergi is widely used with Octopus Agile because of its open API and Home Assistant compatibility. The Ohme Home Pro also supports Agile rate-responsive scheduling.
Can negative rates occur on Octopus Agile? Yes. During periods of high renewable generation and low demand, Agile rates can fall below 0p/kWh. Octopus credits your account at the negative rate for every unit you consume during those periods. This can occur for several consecutive half-hour slots during windy overnight periods.
Should I use Octopus Agile or Intelligent Go for my EV? If you want a simple, fixed off-peak rate with automated scheduling, Octopus Intelligent Go is better. If you are home frequently, use smart home automation, and want to capture the cheapest rates across the full day — including potential negative periods — Agile can deliver better average costs. See our Intelligent Go vs Agile comparison.
