What is the Octopus Energy EV tariff and who is it for?

Octopus Energy EV tariffs are time-of-use electricity tariffs designed for EV owners, offering cheaper off-peak rates for charging at home. They can also suit households that can shift other electricity use (like washing or dishwashing) into off-peak hours. Check eligibility and requirements on this page before switching.

How do I get the cheapest EV charging rate with Octopus?

To get the cheapest home EV charging costs, charge mainly during the tariff’s off-peak window(s) and schedule your charger (or your car) to start automatically at those times. If you’re comparing options, look at the off-peak unit rate, peak unit rate and any standing charge together—then estimate costs based on how much you’ll charge off-peak versus peak.

Do I need a smart meter for an Octopus EV tariff?

Most EV time-of-use tariffs require a working smart meter so your electricity usage can be billed at different rates depending on the time of day. If you don’t have one yet, you may need to arrange installation before you can move onto the tariff.

Can I use an Octopus EV tariff if I don’t have an electric car?

Some EV-focused tariffs are intended for EV owners and may have eligibility checks, while others can be used by any household that benefits from cheap off-peak electricity. If you don’t have an EV, compare the overall costs (including peak rates and standing charge) to ensure it still saves you money.

Will an Octopus EV tariff reduce my electricity bill?

It can, especially if you charge your EV (and run other appliances) mostly during off-peak hours. Savings depend on your charging habits, how much electricity you use at peak times, and the standing charge. A quick cost comparison using your typical monthly kWh and charging schedule is the best way to estimate savings.

Is there a penalty for switching tariffs or leaving Octopus?

Exit fees and contract terms vary by tariff. Before switching, confirm whether the tariff is fixed or flexible and check if there are any exit fees or minimum terms. This helps avoid unexpected costs if you decide to change again later.

Can I combine an EV tariff with solar panels or home battery storage?

Yes, many households pair time-of-use tariffs with solar and/or a home battery to maximise low-cost energy—charging the battery off-peak and using stored energy during peak times. Whether it’s worthwhile depends on your export tariff, battery capacity and how much energy you can shift out of peak hours.

Compare Octopus Energy EV tariff options (and the rest of the market)

Octopus has well-known EV tariffs, but the best EV electricity tariff depends on your household usage, your overnight charging routine, and whether your meter can support half-hourly readings. EnergyPlus is a whole-of-market UK comparison service, so you can check Octopus options alongside other EV and smart tariffs in one place.

Tip: An EV tariff can be excellent for overnight charging, but it’s not automatically the cheapest overall. The daytime unit rate and standing charge matter just as much if you work from home, use electric heating, or cook a lot on electricity.

What is the Octopus Energy EV tariff?

An EV electricity tariff is designed to make charging your electric vehicle at home cheaper by offering a lower unit rate during specific off-peak hours (often overnight). Octopus is one of the best-known providers of EV-friendly tariffs, but they’re not the only option—and prices and structures change.

EnergyPlus helps you compare:

Off-peak charging windows

When the cheaper EV rate applies (e.g. a fixed overnight block). This matters if your car is only plugged in for limited hours.

Peak rates & standing charges

Some EV tariffs trade a very low overnight rate for a higher daytime rate or standing charge.

Smart requirements

Most EV tariffs require a smart meter (and sometimes half-hourly readings enabled) to track when you use electricity.

We’re not Octopus Energy. We compare whole-of-market home energy tariffs to help you find the best fit for your EV charging and household usage.

Is an Octopus-style EV tariff right for your home?

EV tariffs can be brilliant—if your household can shift enough usage into the off-peak window. Here’s when they tend to make sense.

You charge at home most nights

Regular overnight charging means you can capture more of the cheaper rate and reduce cost per mile versus public charging.

You can shift other usage

Dishwasher, washing machine, immersion heater, or a home battery can help you move electricity use into off-peak hours.

You’ve got (or can get) a smart meter

Most EV tariffs need smart readings to apply the right rates at the right times. We’ll help you check compatibility.

Good match if…

Your EV is typically plugged in overnight
You can schedule charging in your vehicle or charger app
You’re comfortable with variable day/night pricing
You want a clear off-peak window to plan around

Consider alternatives if…

Your household uses lots of electricity in the daytime
You rarely charge at home (e.g. mainly workplace charging)
You don’t have smart meter coverage yet
You’d prefer simple single-rate pricing

How EV tariffs work (and what to compare)

When comparing an Octopus Energy EV tariff with other UK EV tariffs, focus on the total household cost—not just the off-peak headline rate.

Key tariff features

Feature	Why it matters
Off-peak window	Can you realistically charge and run appliances during those hours?
Peak unit rate	High daytime rates can outweigh overnight savings if your usage is daytime-heavy.
Standing charge	A higher standing charge can reduce savings, especially in low-use households.
Smart meter requirement	EV tariffs usually need smart readings; some require half-hourly data enabled.
Exit fees / terms	Important if you may move home or expect prices to change.

A simple way to compare

Estimate your EV charging: miles per week and typical kWh needed.
Check plug-in times: when your car is actually at home and available to charge.
Split home usage: overnight vs daytime (work-from-home changes this a lot).
Compare total annual cost: off-peak savings minus any higher peak rate/standing charge.
Confirm eligibility: smart meter, address, and whether half-hourly readings are enabled.

Not sure about half-hourly readings? Some smart tariffs need half-hourly consumption data. We’ll highlight what’s required based on what you tell us.

Costs & savings: what changes your EV charging bill

Your savings from an Octopus Energy EV tariff (or any EV tariff) mainly depend on how many kWh you can move into the cheaper window. Use the checklist below before you switch.

1) How much you charge at home

If you do most charging at home, the overnight rate has a bigger impact. If you mostly use workplace or public chargers, a standard tariff may suit you better.

2) Daytime electricity use

High daytime usage (home working, electric cooking, electric heating) can reduce savings if the peak rate is higher than your current tariff.

3) Charger scheduling

Being able to schedule charging is key. Many EVs and smart chargers let you set start/stop times to align with off-peak periods.

Common money-savers

Set the EV to charge only during the off-peak window
Run appliances overnight where safe and practical
Use a home battery to store cheap electricity (if you have one)
Review standing charge as well as unit rates

Common mistakes

Comparing only the off-peak unit rate and ignoring the peak rate
Switching before confirming smart meter setup and connectivity
Not checking the off-peak window matches your routine
Forgetting to update EV charger schedules after switching

Eligibility: what you typically need for an EV tariff

Eligibility varies by supplier and tariff, but most EV and smart tariffs (including Octopus-style EV tariffs) have similar requirements.

Usually required

Smart meter installed and sending readings
EV ownership or regular access to an EV for home charging
UK home address (not business supply)
Compatible tariff type for your region/meter configuration

If you’re unsure whether your meter supports half-hourly readings or smart tariffs, submit the form and we’ll guide you through the comparison.

Good to know

Question	What to check
Do I need a smart charger?	Not always. Many EVs can schedule charging themselves, but some tariffs work best with a smart charger/app integration.
Do I need half-hourly data?	Some smart tariffs require half-hourly readings. We’ll flag this during comparison where relevant.
Will my rates differ by region?	Yes. Electricity prices can vary by area due to network costs. That’s why postcode-based comparisons matter.

Octopus Energy EV tariff FAQs

Is Octopus the cheapest EV tariff in the UK?

Sometimes it can be, but it depends on your region and how much electricity you use outside the off-peak window. A whole-of-market comparison is the best way to check what’s cheapest for your home.

Do I need a smart meter for an EV tariff?

In most cases, yes. EV and smart tariffs typically rely on smart meter readings to apply the correct rates at different times of day.

Can I use an EV tariff if I don’t have a home charger?

You can still benefit if you charge at home via a suitable socket arrangement, but a dedicated charger usually makes scheduled overnight charging safer and more convenient. Eligibility depends on the tariff.

Will an EV tariff increase my daytime electricity costs?

It can. Some EV tariffs offer a very low off-peak unit rate but a higher peak rate. That’s why it’s important to compare total household cost, not just overnight charging.

Can I switch EV tariffs if I’m in credit or owe money?

In many cases, yes, but the process depends on your current supplier and account status. If there’s debt, you may need to resolve it first. We’ll explain options based on your situation.

How long does a switch take?

A typical UK energy switch often completes within a few working days, but timings can vary. You won’t lose power—your supply stays on throughout.
