This guide breaks down everything it costs to run an electric car in the UK in 2026. It covers charging costs across home, public and rapid chargers, with real costs. You will also find the latest road tax rates, insurance averages, and servicing costs compared with petrol cars.
⚡ Includes free charging calculator
Thinking about going electric? One of the biggest questions people ask is: how much does it actually cost to run an electric car? The short answer is that EVs are cheaper to run than petrol or diesel cars in most cases. But the exact amount depends on how you charge, what you drive, and how many miles you do.
This guide breaks it all down in plain English. We cover charging costs, road tax, insurance, servicing and more. We have also included tables showing the cheapest EVs to run, the ones with the longest range, and the highest-performance models, so you can compare before you buy.
Charging is the single biggest running cost for an electric car, and where you charge makes a huge difference to what you pay. Based on the average UK electric car battery size of around 60 kWh (models like the Tesla Model 3, Hyundai Ioniq 5 and VW ID.4), here is what a typical full charge costs right now:
The difference is huge. Charging the same car at home on an EV tariff costs over ten times less than using a rapid charger at a motorway service station. That is the single most important thing to know about EV running costs.
There are three main ways to charge, and each one suits a different situation:
The cheapest way to charge. Plug in overnight on an EV tariff and a full charge can cost as little as £4 - £5. A dedicated wallbox costs around £800 - £1,200 to install.
Found at supermarkets, car parks and shopping centres. Good for topping up while you are out, but costs five to eight times more than home charging on an EV tariff.
The fastest option at motorway services. You can add 100 miles of range in 20 - 30 minutes, but it is the most expensive way to charge per kWh.
The Ofgem energy price cap for Q2 2026 (April to June) sets the standard electricity rate at 24.67p per kWh. However, if you switch to an EV-specific tariff such as Octopus Intelligent Go, OVO Charge Anytime, or British Gas Electric Driver, you can charge overnight for as little as 7p per kWh. That is a saving of around 70% compared to the standard rate.
Here is how those rates break down for a full charge of a typical 60 kWh electric car:
| Charging method | Rate per kWh | Full charge cost (60 kWh) | Cost per mile |
|---|---|---|---|
| Home (EV tariff, off-peak) | 7p | £4.20 | ~2p |
| Home (standard tariff) | 24.67p | £14.80 | ~5p |
| Public charger | 50p | £30.00 | ~11p |
| Rapid charger (motorway) | 79p | £47.40 | ~17p |
| Petrol equivalent (45mpg at £1.45/litre) | n/a | n/a | ~15p |
If you can charge at home on an EV tariff, running an electric car costs around 2 - 5p per mile, compared with 14 - 19p per mile for a petrol car. That is a saving of roughly £800 - £1,200 per year for a driver doing 8,000 miles.
Every EV has a different battery size, and everyone pays a different electricity rate. Use our free calculator below to work out exactly what it would cost to charge your specific car. Just pick your make and model, choose where you charge, and we do the maths for you.
If keeping costs low is your main goal, smaller EVs with modest battery sizes are the way to go. They are cheaper to charge, cheaper to insure, and often sit in lower insurance groups. Here are some of the most affordable EVs to run in the UK right now.
| Model | Battery size | Range (WLTP) | Home charge cost (EV tariff) | Insurance group |
|---|---|---|---|---|
| Dacia Spring | 26.8 kWh | 140 miles | £1.88 | 3 - 7 |
| Fiat 500e | 23.8 kWh | 118 miles | £1.67 | 10 - 16 |
| MG4 (51 kWh) | 51 kWh | 218 miles | £3.57 | 15 - 22 |
| BYD Dolphin Surf | 45.4 kWh | 200 miles | £3.18 | 12 - 18 |
| Renault 5 E-Tech (40 kWh) | 40 kWh | 186 miles | £2.80 | 11 - 17 |
| Vauxhall Corsa-e | 50 kWh | 222 miles | £3.50 | 18 - 22 |
| VW ID.3 (45 kWh) | 45 kWh | 215 miles | £3.15 | 14 - 19 |
| Nissan Leaf (40 kWh) | 40 kWh | 168 miles | £2.80 | 16 - 20 |
Home charge costs based on an EV off-peak tariff of 7p per kWh, charging from 0 - 100%. In practice, most people charge from around 20% to 80%, which would cost roughly 60% of the figures above.

If you regularly drive long distances, range matters. A bigger battery means fewer charging stops, but it also means higher charging costs per fill. Here are the EVs with the longest range currently on sale in the UK.
| Model | Battery size | Range (WLTP) | Home charge cost (standard tariff) | Starting price |
|---|---|---|---|---|
| Mercedes EQS 450+ | 107.8 kWh | 453 miles | £26.59 | ~£105,000 |
| Tesla Model S | 100 kWh | 405 miles | £24.67 | ~£80,000 |
| BMW iX xDrive50 | 105.2 kWh | 380 miles | £25.95 | ~£78,000 |
| Hyundai Ioniq 6 (77 kWh) | 77.4 kWh | 338 miles | £19.09 | ~£42,000 |
| Tesla Model 3 Long Range | 82 kWh | 390 miles | £20.23 | ~£43,000 |
| Polestar 2 Long Range | 78 kWh | 368 miles | £19.24 | ~£42,000 |
Home charge costs based on the Ofgem Q2 2026 standard tariff of 24.67p per kWh, charging from 0 - 100%. WLTP range figures are manufacturer estimates; real-world range may be 10 - 20% lower depending on weather, driving style and speed.
Electric cars are known for fast acceleration because electric motors deliver all their power instantly. If performance matters to you, here are some of the quickest EVs you can buy in the UK, along with what they cost to run.
| Model | 0 - 62 mph | Top speed | Battery / Range | Home charge cost (standard tariff) |
|---|---|---|---|---|
| Tesla Model S Plaid | 2.1s | 200 mph | 100 kWh / 390 mi | £24.67 |
| Porsche Taycan Turbo GT | 2.2s | 186 mph | 93.4 kWh / 305 mi | £23.04 |
| BMW iX M60 | 3.8s | 155 mph | 105.2 kWh / 357 mi | £25.95 |
| Tesla Model 3 Performance | 3.1s | 162 mph | 82 kWh / 340 mi | £20.23 |
| Hyundai Ioniq 5 N | 3.4s | 161 mph | 84 kWh / 310 mi | £20.72 |
| Lotus Eletre R | 2.9s | 168 mph | 112 kWh / 304 mi | £27.63 |
Performance EVs tend to sit in higher insurance groups, which means higher premiums. If you are considering one, it is worth getting an insurance quote before you buy. Our guide on electric car insurance costs explains what affects your premium and how to reduce it.
Until April 2025, electric cars paid no road tax at all. That changed. From April 2025, EVs are subject to Vehicle Excise Duty (VED) like petrol and diesel cars.
Here is what EV owners pay now:
| Tax type | Amount | Notes |
|---|---|---|
| First-year rate (new EVs) | £10 | Much lower than petrol/diesel cars |
| Standard rate (year 2 onwards) | £195/year | Same as most petrol/diesel cars |
| Expensive car supplement (list price over £40,000) | £425/year | Applies for 5 years from registration. Threshold rises to £50,000 from April 2026 |
While EVs now pay road tax, the first-year rate is still just £10, which is much less than what most new petrol cars attract. If you need help with the process, our guide on how to pay car tax walks you through it step by step. Company car drivers also benefit from low Benefit-in-Kind (BiK) tax rates. The BiK rate for electric cars is 3% in 2025/26 and rises to 4% from April 2026, which is still far below the 20 - 37% rate for most petrol and diesel cars.
Insurance is one area where electric cars can cost more. The average premium for an EV is around £654 per year, though this varies hugely depending on the model, your age and where you live. Premium models like Teslas can cost over £1,000 per year to insure, while smaller EVs like the VW ID.3 average around £478.
EV insurance tends to be higher because of expensive battery replacements, specialist repair requirements and a shortage of qualified EV mechanics. However, the gap between EV and petrol car insurance is closing as the market grows.
Battery packs can cost £5,000 to £20,000+ to replace. EVs need specialist technicians with IMI TechSafe qualifications. Repair times are around 14% longer on average. Parts are often only available from the manufacturer. All of this pushes up the cost of claims, which pushes up premiums.

This is where electric cars really shine. EVs have far fewer moving parts than petrol or diesel cars. There is no engine oil, no clutch, no gearbox, no exhaust system and no timing belt. That means fewer things to go wrong and lower servicing bills.
On average, servicing an EV costs 30 - 40% less than a comparable petrol car. However, there are still some costs to be aware of:
| Item | EV | Petrol car |
|---|---|---|
| Annual service | £100 - £200 | £150 - £350 |
| Brake pads | Last longer (regenerative braking) | Every 25,000 - 50,000 miles |
| Tyres | May wear faster (higher torque) | Standard wear |
| Coolant | Battery coolant replaced periodically | Engine coolant replaced periodically |
| MOT (after 3 years) | Required (no emissions test) | Required (includes emissions test) |
One thing to watch out for is tyre wear. Because electric cars are heavier and deliver instant torque, tyres can wear out faster. Some EV-specific tyres cost a bit more too, so it is worth budgeting for this.
Here is how the overall annual running costs compare for a typical driver doing 8,000 miles per year, based on 2026 UK figures.
| Cost | Electric car | Petrol car |
|---|---|---|
| Fuel / charging | £160 - £400 | £1,100 - £1,500 |
| Road tax (VED) | £195 | £195 |
| Insurance | £500 - £1,000 | £400 - £800 |
| Servicing | £100 - £200 | £200 - £400 |
| Total annual running cost | £955 - £1,795 | £1,895 - £2,895 |
Even with higher insurance, an electric car could save you £500 - £1,100 per year in running costs compared to a petrol equivalent. The biggest saving comes from charging at home on an EV tariff instead of filling up at the pump.
EV tariffs like Octopus Intelligent Go offer off-peak rates as low as 7p per kWh. If you charge overnight, you could save £500 or more per year compared to a standard tariff.
A dedicated home charger costs £800 - £1,200 to install but pays for itself quickly through cheaper charging. The government grant covers up to £350 for renters and flat owners.
Charging to 80% is faster, cheaper per session, and better for your battery's long-term health. Most daily driving only needs 20 - 80% charging.
Many supermarkets (Tesco, Lidl, Aldi) and retail parks offer free EV charging while you shop. Apps like Zap-Map help you find them.
If you have solar panels, charging your EV during the day with excess solar energy is effectively free. A solar and EV combination can cut your motoring costs dramatically.
