Estimates depend on your meter, region, usage and supplier availability. We’ll show options that fit your home setup (including smart meter requirements where relevant).
Compare the cheapest EV charging tariffs for your home
If you charge your electric car at home, the cheapest EV charging tariff in the UK is usually the one that gives you a lower off-peak unit rate for several hours overnight (sometimes with a daytime peak rate). After each Ofgem price cap update, suppliers can change prices and new EV plans may become more competitive in your region.
EnergyPlus compares whole-of-market household tariffs (where available), including standard variable, fixed and EV-focused plans. We’ll help you check if a switch could reduce the cost per kWh you pay for charging and lower your overall home energy bill.
Tip: The “cheapest” EV tariff depends on your total household usage, not just EV miles. A very low off-peak rate can be offset by a higher day rate if most of your energy is used in the daytime.
What you’ll need (takes a few minutes)
- Your postcode (to match your regional electricity rates)
- Whether you have a smart meter (many EV tariffs require one)
- Your current supplier/tariff and an idea of annual usage (if known)
- How you typically charge (overnight schedule vs daytime top-ups)
Cheapest EV charging tariff after the price cap: what “after” really means
The Ofgem energy price cap limits the maximum unit rates and standing charges suppliers can set on default tariffs (including Standard Variable Tariffs) for typical customers. It changes periodically, and when it does, the best value EV charging tariff can shift too — especially if you’re choosing between:
- Default vs fixed: Fixed deals may sit below or above the current cap depending on wholesale prices and supplier pricing.
- Single-rate vs time-of-use: EV tariffs can offer low overnight rates but higher peak/daytime rates.
- Electricity-only vs dual fuel: If you add gas, the “best overall” deal can change even if the EV rate looks attractive.
Important: The price cap is not a cap on your total bill. Your bill depends on how much energy you use. EV tariffs help you reduce costs by shifting charging to cheaper hours and/or finding a better household rate.
Why EV charging tariffs can be cheaper than standard tariffs
Lower off-peak kWh pricing
Many EV tariffs reduce your electricity unit rate for a set overnight window. If you schedule charging to those hours, your cost per mile can drop significantly.
Better fit for smart charging
With a compatible smart meter and EV charger/app scheduling, you can automate charging overnight and avoid peak rates without changing your routine.
Potential household savings too
If you can shift other usage (dishwasher, washing machine, immersion heater) into off-peak hours, the value of an EV tariff improves beyond just charging.
Not everyone benefits: If most of your electricity use is during the day and you can’t charge overnight, a standard single-rate tariff may be cheaper overall. Our comparison looks at your household pattern.
How EV charging tariffs work (UK)
EV tariffs are typically time-of-use electricity plans. You pay different unit rates depending on the time of day. The cheapest EV charging tariff for your home is the one that best matches when you charge and when your household uses electricity.
- Check your meter: Many EV tariffs require a smart meter (or a meter capable of time-of-use readings).
- Choose a tariff structure: Common options include single-rate, day/night, or multi-rate with a cheap overnight EV window.
- Schedule charging: Set your car or home charger to charge in the low-rate hours where possible.
- Review total costs: Compare the overall annual estimate including standing charge and day rates, not just the EV rate.
- Switch: If the deal works for your home, switching is usually handled by the new supplier with minimal disruption.
Common EV tariff types (at a glance)
Because availability and rates vary by region and meter type, comparing for your postcode is the fastest way to find the cheapest EV charging tariff for your household after the latest price cap change.
EV charging cost examples (and where savings come from)
Home charging cost is driven by kWh used and your unit rate. A typical EV might use roughly 0.25–0.35 kWh per mile depending on vehicle efficiency, temperature and driving style. If you know your efficiency (miles/kWh), you can estimate charging costs more accurately.
Example A: overnight charging on an EV tariff
If you can charge mostly in the off-peak window, you’ll typically pay a lower unit rate for those kWh. That can reduce your cost per mile — particularly if you do higher mileage each week.
- Best when you reliably plug in overnight
- Works well with scheduled charging on your car or charger
- May improve further if you shift other appliances off-peak
Example B: standard single-rate tariff
A standard tariff can be better if you charge at different times, can’t guarantee overnight charging, or your household uses most electricity during the day and would be hit by higher peak rates on some EV plans.
- Simple pricing and easier budgeting
- No need to manage charging windows
- May be cheaper overall for low-mileage drivers
A quick way to sanity-check an EV tariff
Ask: How many kWh will I charge off-peak each month? Then compare the off-peak savings against any extra cost you might pay on the daytime unit rate and standing charge. If you share your postcode and meter setup in the form above, we’ll help with the comparison.
Eligibility: smart meters, EV chargers and switching
Do I need a smart meter?
Often, yes. Many time-of-use and EV tariffs rely on half-hourly readings to apply different rates by time. If you don’t have a smart meter, you may still find suitable fixed or standard deals, and in some cases you can switch first and arrange installation with your supplier.
Do I need a specific EV charger?
Not always. Many drivers schedule charging using the car itself. Some tariffs work best with a smart charger and an app, but eligibility varies by supplier. We’ll surface options that suit your setup.
Will switching interrupt my supply?
No. You won’t lose power during an energy switch. Your supply stays on; the admin changes happen in the background. You’ll usually just submit a meter reading when asked.
What about exit fees?
If you’re on a fixed tariff, you may have an exit fee for leaving early. We recommend checking your current plan before switching. If you fill the form, we can help you factor this into the decision.
Common mistakes when looking for the cheapest EV charging tariff
Only comparing the off-peak rate
A very low overnight unit rate can look brilliant, but the day rate and standing charge can make the total annual cost higher for some homes.
Not checking your meter compatibility
If you don’t have a smart meter (or you’re not set up for time-of-use readings), your tariff options can be limited. We’ll highlight plans suitable for your meter.
Charging outside the cheap window
If you forget to schedule charging, you may pay peak rates. The cheapest EV tariff only stays cheap if your charging pattern matches the tariff structure.
FAQs: cheapest EV charging tariff in the UK (after the price cap)
Does the price cap apply to EV charging tariffs?
The Ofgem price cap applies to default tariffs (like standard variable tariffs) rather than every time-of-use or fixed EV tariff in the same way. EV tariffs can still be competitive, but you should compare the full pricing structure and total annual cost for your home.
Is an EV tariff always cheaper than a normal tariff?
No. EV tariffs are usually best if you can charge overnight and shift a meaningful share of your electricity into the off-peak window. If you have high daytime usage or charge at random times, a good single-rate fixed tariff may be cheaper overall.
What if I have solar panels or a home battery?
Solar, batteries and export tariffs can change what “cheapest” looks like. Some households use off-peak electricity to top up a battery, then run the home during peak hours. When you compare with EnergyPlus, mention your setup so we can help you choose a tariff that fits.
Can I switch if I’m renting?
Usually, yes — if you pay the energy bills and your name is on the account. If you’re unsure, check your tenancy agreement and confirm with your landlord. EV tariffs may also depend on whether you can install or use a home charger.
How quickly can I change to a cheaper EV tariff?
Switch times vary by supplier and your circumstances, but many switches complete within days to a few weeks. Your supply won’t be interrupted. If you’re on a fixed tariff, check any exit fees and the end date before switching.
What’s the best way to find the cheapest tariff in my area?
Compare using your postcode and your meter type. Electricity prices vary by region (including standing charges), and EV tariff eligibility can depend on smart meter status. Use the form at the top of this page to see options tailored to your home.
