How off-peak charging works

Choosing the right EV energy tariff

Rates checked: August 2026

The best EV tariff depends on your driving habits, vehicle, and household energy use. Some tariffs offer low-cost charging exclusively for your EV; others give off-peak rates for your entire home, so you can also save by running washing machines, tumble dryers and dishwashers overnight. Compare peak rates, standing charges and contract terms before switching, and note that most EV tariffs require a smart meter.

* Peak rates vary by location and for new versus existing customers. This is a guide only: EV tariffs change frequently, so always check the provider's website for the latest rates in your area before switching.

Tariffs with whole-home off-peak rates can save you even more if you run energy-hungry appliances such as dishwashers, washing machines and tumble dryers overnight. Watch out for higher peak rates, standing charges and exit fees: a low off-peak rate isn't automatically the cheapest tariff overall for your household.

Expert FAQ

Cord experts say

“Take your time choosing the best EV tariff for you. Most people only need to charge a few times a week, so quite often a simple overnight tariff might be best. Always check the daytime rates, standing charges, small print and any exit fees. But whichever you choose, you can be sure that you'll be saving a huge amount vs a petrol or diesel vehicle!”

Your questions, answered by Cord's experts

Do Cord chargers work with Octopus Intelligent Go?

Yes. Cord chargers integrate directly with Octopus Intelligent Go. Octopus normally asks for a compatible car before you can join the tariff, but you can connect through your Cord charger instead, which opens Intelligent Go (and EV Saver) to any EV. Once connected, Octopus schedules your charging automatically in the cheapest slots, including bonus cheap rates during the day when the grid is green, so you charge from around 7p/kWh without lifting a finger.

How long does it take to charge an EV each week?

Honest answer: it depends on your weekly mileage, your car's efficiency, and your charger speed. With a Cord 7.4kW charger and typical efficiency of 3.5 miles per kWh, here's what you'd typically see: around 100 miles a week needs about 4 hours of charging; 200 miles a week, the average UK commuter, needs about 8 hours; 400 miles a week needs about 16 hours. Even high-mileage drivers fit comfortably inside two or three overnight off-peak windows.

How do EV tariffs and bolt-ons work?

EV tariffs offer cheaper electricity during off-peak hours, usually overnight, and your Cord charger can be scheduled to use exactly those hours. Some providers offer bolt-ons instead, like OVO Charge Anytime and EDF Smart Charging, which sit alongside your existing tariff and cover EV charging only. Intelligent tariffs like Octopus Intelligent Go go a step further and automatically charge your car whenever energy is cheapest. Reminder Always check the small print. Off-peak savings can be offset by higher peak rates and standing charges, and some tariffs carry early exit penalties.

Which is the best Octopus tariff?

Octopus offers several EV tariffs. Go gives a fixed overnight window, simple and predictable. Intelligent Go offers 42 off-peak hours a week and can unlock extra cheap slots during the day. EV Saver is Intelligent Go with rates a penny cheaper, reserved for drivers leasing through Octopus Electric Vehicles. Agile tracks wholesale prices half-hourly, attractive on paper but harder for busy households in practice. And here's where Cord helps: Octopus normally requires a compatible car for Intelligent Go, but you can connect through your Cord charger instead, opening the tariff to any EV.

What other tariffs are there?

Plenty. OVO Charge Anytime, ScottishPower EV Saver, British Gas Electric Driver, EDF Go Electric Overnight, E.ON Next Drive and more. Most offer whole-home off-peak rates, so savvy households can save well beyond the car by running appliances overnight. All of them work with Cord: set your off-peak window in the Cord app. Reminder Some tariffs rely on newer technology and direct integration with your car or charger, so set-up can occasionally take a little patience. If you get stuck, our support team can help.

Do I need a smart meter?

Almost always, yes. Most EV tariffs require one so your supplier can bill your off-peak usage separately. Check with your provider before switching.

Will my Cord charger still work if I switch tariff later?

Yes. Cord chargers aren't locked to any supplier. If you switch, just update your off-peak schedule in the Cord app, or reconnect the relevant integration.
