The cost to charge an electric car in the UK varies significantly, from as little as £5-7 for a full charge at home to over £30-40 for a rapid public charge. The final price depends entirely on three key factors: where you charge (home vs. public), your electricity tariff, and your car's size.
For most EV owners, charging overnight at home is by far the most cost-effective method. On a standard variable tariff (around 28p per kWh), filling a 60 kWh battery—common in models like the Kia e-Niro or Hyundai Kona Electric—would cost approximately £16.80. However, switching to a dedicated EV tariff can slash this cost. These tariffs offer ultra-low overnight rates, sometimes as low as 7-9p per kWh, bringing the cost for the same charge down to just £4.20-£5.40.
Public charging is more expensive and complex. Networks like Pod Point or Source London often provide slower 7kW charging for a session fee or a pence-per-kWh rate similar to home charging. The real expense comes with rapid chargers (50kW+) and ultra-rapid chargers (100kW+), used for long journeys. Providers like Ionity or BP Pulse can charge 69p per kWh or more, making a quick top-up costly.
Here’s a quick comparison for a 60 kWh battery:
| Charging Method | Typical Cost per kWh | Estimated Full Charge Cost (60 kWh) | Best For |
|---|---|---|---|
| Home (Standard Tariff) | 28p | £16.80 | Daily use, lowest long-term cost |
| Home (EV Tariff) | 9p | £5.40 | Overnight charging, maximum savings |
| Public Slow/Fast (AC) | 45p | £27.00 | Shopping, work, medium-duration stops |
| Public Rapid (DC) | 65p | £39.00 | Motorway journeys, quick top-ups |
Ultimately, to minimize costs, prioritize home charging with a specialist EV tariff and use public rapid chargers sparingly for long-distance travel.

It's a classic "how long is a piece of string?" question, but for my Leaf, I budget about £8-10 for a full charge at home on my economy tariff. That gets me around 150 miles, which is way cheaper than my old petrol car. Public charging is a different story—I only use it on longer trips, and it can easily cost £20-25 for a 80% charge. My advice? Get a smart meter and a good home electricity deal; that's where you'll save the real money.

Beyond the simple price per kilowatt-hour (kWh), think about your overall energy contract. The key to affordable EV ownership is decoupling your charging cost from peak electricity rates. If you can charge overnight, a dedicated EV tariff is transformative. My provider charges 7.5p/kWh between midnight and 5 am. For my car's 77 kWh , a full charge costs under £6, compared to over £20 on the standard rate. The slight premium on my daytime electricity is negligible compared to the savings on fuel. It requires a lifestyle adjustment, but the financial payoff is substantial.

As someone who drives all over the country for work, I live at public charging stations. The cost is all over the place. On a motorway, a rapid charge might be 69p per kWh, costing me £25 for 30 minutes. But in a city centre car park, I might find a slower charger for 30p per kWh. I use apps like Zap-Map to compare prices in real-time before I plug in. It's definitely more expensive than home charging, but for the convenience and the miles I cover, it's still cheaper than diesel. You just have to be and plan your stops.

Don't just focus on the charging cost; consider the total cost against petrol. My electric SUV has a 70 kWh . Even at a pricey public rapid charger (65p/kWh), a full £45 charge gives me about 250 miles. To drive the same distance in a similar petrol SUV would cost over £70 at current fuel prices. The savings are even more dramatic with home charging. While the upfront price at the rapid charger seems high, it's crucial to view it through the lens of what you're no longer spending on fossil fuels. The per-mile cost is still the winner.
