Find the cheapest home EV charging tariff near you
EV electricity prices vary by postcode because suppliers price energy differently across distribution regions (and sometimes by meter type). That’s why the “cheapest EV tariff in the UK” might not be the cheapest in your area.
EnergyPlus lets you compare whole-of-market tariffs designed for home charging — including off-peak / overnight rates from 6.7p to about 9p per kWh, smart tariffs, and deals that suit EV owners who can shift usage to cheaper hours.
Tip: If you charge mainly overnight, the cheapest option is often a tariff with a low off-peak unit rate — but the standing charge and peak rate still matter for your overall bill.
Looking for the cheapest way to charge at home? Focus on: off-peak unit rate, off-peak hours, standing charge, and whether you can shift usage (laundry/dishwasher/immersion) into the cheaper window.
Best home EV charging tariffs in the UK — July 2026
These are the leading smart EV tariffs available to UK home chargers this month. Off-peak unit rates apply during a set overnight window; outside that window you pay your supplier’s standard day rate. Availability, exact rates and windows depend on your postcode, supplier and meter — enter your postcode above to see what you can actually switch to.
| EV tariff | Off-peak rate | Off-peak window | Good to know |
|---|---|---|---|
| Octopus Intelligent Go | 7p/kWh | 23:30–05:30 (smart 6-hour window, can extend automatically) | Average saving around £771/yr vs standard variable; needs a compatible car/charger and smart meter. |
| E.ON Next Drive | ~6.7p/kWh | Overnight off-peak window | Cheapest headline night rate in July 2026; requires a smart meter. |
| OVO Charge Anytime | ~7p/kWh | Charges your car at the off-peak rate any time of day | Add-on to an OVO home plan; smart charging via compatible vehicle/charger. |
| British Gas Electric Driver | ~8.95p/kWh | Set overnight off-peak window | Widely available EV tariff; still far below the day-rate cap. |
How off-peak compares with the cap: From 1 July 2026 the Ofgem cap sets a typical electricity unit rate of 26.11p/kWh (with a 57.19p/day standing charge), as part of an £1,862/yr typical dual-fuel bill. Charging at 7p/kWh instead of 26.11p/kWh cuts the cost of every overnight kWh by roughly 73% — that’s the core saving an EV tariff delivers.
Why the cheapest EV charging tariff changes by postcode
Regional electricity pricing
Your postcode maps to a distribution region. Standing charges and unit rates can vary by region — the 26.11p/kWh and 57.19p/day cap figures are GB averages, so your local rate may be a little higher or lower — which affects which tariff comes out cheapest for your household.
EV tariffs aren’t one-size-fits-all
Some EV deals offer very low night rates but higher daytime prices. If you’re home during the day, a “cheap overnight” tariff can cost more overall.
Meter & eligibility requirements
Many smart tariffs need a smart meter (or installation). Multi-rate tariffs may suit EV owners, but they also require the right meter set-up.
Your charging habits matter
If you charge 2–3 times a week, the best tariff may differ from someone charging nightly. We help you compare based on what’s available where you live.
Whole-of-market comparison
EnergyPlus checks a broad range of suppliers and tariffs, helping you avoid missing a deal that’s competitive in your region.
How to find the cheapest home EV tariff (and switch)
If you want the cheapest home EV charging tariff by postcode, the key is to compare the full tariff structure — not just the headline “overnight” rate.
- Enter your postcode to match you with tariffs available in your distribution region.
- Tell us about your meter (smart, single-rate, Economy 7). This affects eligibility and pricing.
- Compare EV-friendly options including off-peak windows, peak rates and standing charges.
- Choose the best fit for your charging times and overall home usage.
- Submit the form and we’ll guide you through the next steps to switch your home supply.
Switching basics: Switching is free and usually takes around five working days — and you can switch even without a smart meter, though the very cheapest smart EV rates do need one. You don’t need to change your EV charger to change your electricity tariff: your supplier changes; your home wiring and charger stay the same.
EV tariff rates explained (what to compare)
To identify the cheapest electricity tariff for home EV charging, compare these items on every quote you receive:
| What you’re comparing | Why it matters for EV charging | What to look for |
|---|---|---|
| Off-peak unit rate (p/kWh) | This is typically the rate you’ll pay when charging overnight. | Lower is better — July 2026 leaders run 6.7p–8.95p/kWh — but check the hours it applies to. |
| Off-peak window | A cheap rate is only useful if you can charge within the window. | Aim for a window that matches your schedule (e.g. 23:30–05:30 on Octopus Intelligent Go). |
| Peak unit rate (p/kWh) | Most of your home usage may still be daytime/evening. | Check it’s not so far above the 26.11p/kWh cap rate that it offsets EV savings. |
| Standing charge (p/day) | Paid every day regardless of how much you use (cap: 57.19p/day for electricity). | Especially important for lower-usage homes and flats. |
| Exit fees / contract length | A “cheap” tariff may lock you in. | Prefer flexible terms unless the savings are clear. |
Quick home charging cost check (simple estimate)
A rough way to estimate your EV charging cost at home:
Cost to charge (approx.) = EV kWh added × unit rate (p/kWh) ÷ 100
Example (using July 2026 rates):
- Charge adds 30 kWh overnight
- Off-peak EV rate 7p/kWh: 30 × 7 ÷ 100 = £2.10
- Same 30 kWh at the 26.11p cap day rate = £7.83 — over £5.70 more per charge
Actual costs vary by car efficiency, charging losses, and your tariff structure. The goal is to choose a tariff that’s cheapest for your mix of EV charging and household electricity use.
Regional considerations: what to remember when comparing by postcode
Distribution region impacts
Two households on the same tariff name can still pay different standing charges and unit rates, depending on postcode. The cap’s 26.11p/kWh and 57.19p/day are GB averages — your region sets the exact figures. Always compare using your exact address details.
Smart meter availability
The cheapest EV charging tariffs — Octopus Intelligent Go, E.ON Next Drive, OVO Charge Anytime — are smart tariffs. If you don’t have a smart meter, we’ll highlight suitable alternatives and options that include installation.
Charging set-up
Whether you use a dedicated home charger, a 3-pin plug (not recommended for regular use), or scheduled charging via the vehicle, your ability to use off-peak hours affects savings.
Common mistakes that stop you getting the cheapest EV electricity
- Choosing based on off-peak rate only, ignoring peak rate and standing charge
- Not checking the off-peak window lines up with when you can charge
- Assuming an EV tariff is always best even if you rarely charge at home
- Forgetting that electricity-only vs dual fuel can change overall value

FAQs: cheapest home EV charging tariff UK by postcode
What is the cheapest EV charging tariff in July 2026?
E.ON Next Drive has the cheapest headline night rate at around 6.7p/kWh, with Octopus Intelligent Go (7p/kWh, 23:30–05:30) and OVO Charge Anytime (~7p/kWh) close behind. British Gas Electric Driver is about 8.95p/kWh. All sit far below the 26.11p/kWh July price-cap day rate. The best one for you depends on your postcode, car/charger and meter.
How much can an EV tariff save me?
Octopus quotes an average saving of around £771 a year on Intelligent Go versus standard variable rates. The exact figure depends on your mileage and how much charging you can shift into the off-peak window — every kWh moved from the 26.11p cap rate to 7p saves about 19p.
Why do EV charging tariffs vary by postcode?
Energy prices can vary across UK distribution regions, and suppliers may set different standing charges and unit rates by region. The price cap itself is a unit-rate cap, not a total-bill cap, and uses GB averages — your postcode determines which regional prices actually apply.
Do I need a smart meter to get the cheapest EV tariff?
Often, yes — the cheapest smart EV tariffs use half-hourly smart-meter readings to apply the off-peak rate. But not always. Some multi-rate or fixed tariffs can still be competitive depending on your postcode and usage, and you can switch supplier even without a smart meter. We’ll show suitable options for your set-up.
Is an EV tariff worth it if I only charge occasionally?
Not always. If most of your electricity use is at peak times and you charge rarely, a standard tariff with a lower standing charge or better peak rate may be cheaper overall. Comparing by postcode helps you see the real total cost.
Can I get cheap EV charging without changing supplier?
Sometimes your current supplier offers an EV-friendly tariff, but it may not be the cheapest in your area. A whole-of-market comparison checks wider availability, based on your postcode and eligibility.
Will switching affect my EV charger or installation?
No. Switching changes who supplies your electricity and the tariff you’re on. Your home charger hardware stays the same, and the switch is free and usually completes in about five working days.
Is this page for business EV charging?
No — this comparison is for UK homes. If you’re looking for workplace or business energy, you’ll need a different set of tariffs and eligibility checks.
