"How long does it take to charge?" is probably the most common question new EV owners ask — and the most frustrating to answer, because the honest reply is always "it depends." It depends on your car's battery size, the type of charger you're using, your car's onboard charger limit, and whether you're charging from empty or just topping up. But don't worry — this guide breaks it all down in plain English, with a charging time table for the most popular EVs in the UK.
⚡ The quick answer: On a typical 7kW home wallbox, most EVs charge from near-empty to full in 6–11 hours — easily done overnight. A 3-pin plug takes 2–3 times longer. In daily use, you'll rarely charge from empty, so most overnight sessions are 3–5 hours.
## The Three Types of Home Charging There are three ways to charge an EV at home in the UK. Each delivers power at a very different speed: ### 1. Three-Pin Plug (Granny Charger) — 2.3kW Every EV comes with a cable that plugs into a standard domestic socket. It's the slowest option by far, adding roughly **8–10 miles of range per hour**. A full charge for a typical 60kWh battery takes over 24 hours. It works in a pinch — especially if you drive short distances daily — but it's not practical as your main charging method. The wiring in most UK homes isn't designed for sustained high loads, and drawing 2.3kW for 20+ hours continuously can stress older circuits. **Best for:** Emergency use, or very low-mileage drivers who only need 20–30 miles per day. ### 2. Dedicated 7kW Wallbox — The UK Standard A 7kW home charger (technically 7.4kW on a single-phase supply, but everyone rounds down) is the standard for UK homes. It adds roughly **25–30 miles of range per hour**, meaning most EVs fully charge in **6–11 hours** — perfect for overnight charging. This is what the vast majority of UK EV owners install, and it's what we recommend. Models like the [Ohme Home Pro](/reviews/ohme-home-pro-review/), [Myenergi Zappi](/reviews/myenergi-zappi-2-review/), and Pod Point Solo 3 all deliver 7kW. The [OZEV grant](/guides/ev-charger-government-grant-uk/) covers up to £350 towards installation. **Best for:** The vast majority of UK homeowners. Overnight charging covers daily driving needs comfortably. ### 3. 22kW Wallbox — Three-Phase Only A 22kW charger delivers roughly **80–90 miles of range per hour** and can fully charge most EVs in **2–4 hours**. However, there's a significant caveat: **22kW charging requires a three-phase electricity supply**, which most UK homes don't have. Three-phase power is common on commercial premises and some newer-build homes, but the vast majority of UK residential properties run on single-phase. Upgrading to three-phase typically costs £1,000–£3,000 and requires your local Distribution Network Operator (DNO) to approve and install it. There's another limitation too: many EVs have an onboard charger that maxes out at 7kW or 11kW on AC, meaning they physically cannot charge faster than that regardless of what your wallbox delivers. More on this below. **Best for:** Homes with existing three-phase supply (some new builds, rural properties, or homes with solar/battery systems). Not worth the upgrade cost for most people. ## The Charging Time Table — 12 Popular UK EVs Here's how long each of the most popular UK EVs takes to charge from 10% to 80% (the realistic daily charging range) on each type of home charger:

*\*22kW column assumes three-phase supply is available.* *†Limited to 11kW by the car's onboard charger, even on a 22kW supply.* *‡Limited by the car's onboard charger to less than 7kW.* **Times are for 10% to 80% charge (70% of battery capacity).** A full 0–100% charge takes roughly 40% longer, but charging from 0% and to 100% is both uncommon in daily use and harder on the battery. ## Why Not All Cars Charge at the Same Speed You might wonder why a 22kW wallbox doesn't always charge three times faster than a 7kW one. The answer lies in the **onboard charger** — a component inside every EV that converts AC electricity from your home supply into DC electricity for the battery. ### The Onboard Charger Bottleneck Every EV has a maximum AC charging rate determined by its onboard charger: - **6.6kW:** Nissan Leaf — this car physically cannot charge faster than 6.6kW from any AC source, so a 7kW wallbox only delivers 6.6kW - **7.4kW:** Peugeot e-208, Vauxhall Corsa Electric — these max out at 7.4kW, matching a standard UK wallbox perfectly - **11kW:** Tesla Model 3/Y, VW ID.3/ID.4, Hyundai Ioniq 5, Kia EV6, BMW iX, MG4, MINI Electric — these can accept up to 11kW, but on a UK single-phase 7kW supply, they'll charge at 7kW - **22kW:** Renault Megane E-Tech, some Mercedes EQ models — these can use the full 22kW from a three-phase supply The key takeaway: **your charging speed is limited by the slower of either your charger or your car's onboard charger.** Buying a 22kW wallbox for a car with a 7kW onboard charger won't make it charge any faster. ### Battery Size Matters Too A larger battery takes longer to charge — simple maths. The MINI Electric with its compact 36.8kWh battery charges from 10–80% in under 4 hours on a 7kW wallbox. The BMW iX with its 76.6kWh battery takes nearly 8 hours. But larger batteries also mean more range per charge, so you're charging less frequently. An iX might only need charging once or twice a week for average commuting, while the MINI might need it every other day. ### Temperature Affects Charging Speed Cold weather slows charging. In winter, your EV's battery management system may reduce the charging rate to protect the battery, adding 10–20% to charging times. This is normal and nothing to worry about — you'll barely notice the difference with overnight charging, since you have plenty of time. ### The 80% Sweet Spot EV batteries charge fastest up to about 80%. After that, the charging rate slows significantly as the battery management system protects the cells. This is why we quote 10–80% times — it's the practical charging range for daily use. For home charging, this doesn't really matter. You'll typically plug in with 40–60% battery and let it charge overnight to 80%. Your car's app or the charger's app lets you set the target so it stops at 80% automatically. ## Real-World Charging: What It Actually Looks Like Here's the thing most charging time discussions miss: **you rarely charge from empty.** The average UK driver covers about 20 miles per day (7,400 miles per year). In a typical EV averaging 3.5 miles per kWh, that's about 5.7kWh of electricity per day — less than an hour's worth of charging on a 7kW wallbox. Most EV owners plug in when they get home, and the car tops up overnight. A typical weekday charge might be: - **Arrive home at 70% battery** - **Plug in, set target to 80%** - **Smart charger waits for off-peak hours** (if on an [EV tariff](/guides/best-ev-tariff-uk-2026/)) - **Charges for 1–2 hours during off-peak window** - **Car is ready at 80% by morning** It's more like charging a phone than refuelling a petrol car. You don't wait until the tank is empty — you just plug in each evening and it takes care of itself. ## Which Charging Speed Do You Actually Need? For the vast majority of UK homeowners, **a 7kW wallbox is all you need**. Here's why: - It charges fast enough to fully replenish most EVs overnight (6–11 hours from near-empty) - Daily top-ups take 1–3 hours - It works with single-phase power (which 99% of UK homes have) - All [smart EV tariffs](/guides/best-ev-tariff-uk-2026/) have enough off-peak hours to charge at 7kW - The [OZEV grant](/guides/ev-charger-government-grant-uk/) covers installation costs up to £350 The only scenario where you might want faster home charging is if you have three-phase power already, a car with a higher onboard charger rate (11kW+), and very high daily mileage. Even then, a 7kW charger would likely handle it overnight. **Don't waste money upgrading to 22kW unless you already have three-phase power and a clear need for it.** ## How to Speed Up Your Home Charging If you're currently on a 3-pin plug and want faster charging, the answer is simple: **get a dedicated wallbox installed.** It'll charge roughly 3x faster and is far safer for long-duration charging. If you already have a 7kW wallbox: 1. **Charge overnight during off-peak hours** — not faster, but cheaper. A [smart charger](/guides/smart-ev-charger-explained/) handles this automatically. 2. **Keep your battery between 20–80%** — charging is fastest in this range. 3. **Pre-condition your car in winter** — warming the battery before charging (most EVs can do this via their app) helps maintain charging speed in cold weather. 4. **Check your car's onboard charger rate** — if it's 11kW, you're already getting the maximum from a UK single-phase supply. --- ## FAQs ### Can I charge my EV overnight on a 3-pin plug? For most EVs, a 3-pin plug won't fully charge a large battery overnight. At 2.3kW, you'd add about 18–20kWh in 8 hours of overnight charging — enough for roughly 60–70 miles of range. That's fine for very low daily mileage, but a 7kW wallbox is a much more practical long-term solution. See our [installation cost guide](/guides/home-ev-charger-installation-uk/) for what a wallbox costs. ### Does charging speed affect battery health? Home charging at 7kW or below is very gentle on EV batteries — it's fast DC charging (50kW+) that causes the most wear over time. Charging at home overnight is actually the best thing you can do for battery longevity. Setting a charge limit of 80% (rather than 100%) also helps preserve long-term battery health. ### Why does my EV charge slower than the wallbox rating? Most likely because your car's onboard charger has a lower maximum rate than your wallbox. For example, a Nissan Leaf can only accept 6.6kW on AC, so even a 7kW wallbox will only deliver 6.6kW. Cold weather and battery state of charge can also reduce charging speed. Check your car's specifications for its maximum AC charging rate. ### Is a 7kW charger fast enough for daily use? For the vast majority of UK drivers, absolutely yes. The average daily drive is about 20 miles, which takes about 1 hour to replenish on a 7kW charger. Even if you drive 50–60 miles per day, a 7kW charger will comfortably replace that in 2–3 hours of overnight charging. You'd need to drive well over 100 miles daily before a 7kW charger becomes insufficient. ### How long does it take to add 100 miles of range? On a 7kW wallbox, roughly 3–4 hours depending on your car's efficiency. On a 3-pin plug, about 10–12 hours. On a 22kW charger (if your car supports it), about 1–1.5 hours. For most EVs averaging 3.5 miles per kWh, 100 miles requires about 28.5kWh of electricity. --- *See also: [How Much Does It Cost to Charge an EV?](/guides/ev-charging-cost-uk-2026/) · [Best EV Energy Tariffs 2026](/guides/best-ev-tariff-uk-2026/) · [Best Home EV Chargers UK](/best-picks/best-home-ev-chargers-uk/) · [Ohme Home Pro Review](/reviews/ohme-home-pro-review/)*
