Key takeaways
- Charging at home on the standard price cap costs 26.11p per kWh from 1 July 2026, so a full 64kWh battery works out at around £17.
- An off peak EV tariff such as Intelligent Octopus Go drops the rate to around 8p per kWh, or roughly £5 for a full charge.
- Public rapid and ultra rapid charging averaged about 79p per kWh in June 2026, with the main networks ranging from 61p to 92p per kWh.
- Public charging carries 20% VAT while home electricity carries only 5%, which widens the gap further.
- Per mile, home charging costs roughly 2p to 8p, while public rapid charging costs about 24p, broadly comparable to petrol.
The cost of charging an electric vehicle in the UK depends almost entirely on where you plug in. Charge at home on the standard energy price cap and a full family-sized battery costs around £17. Use a public rapid charger for the same top-up, and you can pay more than double.
This guide sets out electric car charging costs for 2026 across home charging, off-peak tariffs and the public network. Every figure below reflects current UK rates, so you can see the real charging EV price for your own driving and budget accordingly.
How much does it cost to charge an electric vehicle in the UK?
The cost of charging an electric vehicle in the UK ranges from around £5 to more than £40 for a full family-sized battery. The exact figure depends on where you charge, the tariff you are on and the size of your battery. Home charging is by far the cheapest option.
As a rough guide for a typical 64kWh battery, expect around £5 on an off-peak EV tariff, about £17 on the standard home rate, and roughly £40 on a public rapid charger. The sections below break down each of these electric car charging costs in detail.
What does it cost to charge an electric car at home?
Charging at home on a standard variable tariff costs 26.11p per kWh from 1 July to 30 September 2026, based on the Ofgem energy price cap for a typical Direct Debit customer including 5% VAT. Filling a 64kWh battery from empty to full therefore costs around £17.
That national average rate varies by region, and a daily standing charge of 57.19p applies to your electricity supply whether you charge a car or not. Around 80% of EV charging happens at home, which is why home charging costs dominate what most drivers actually spend across a year.
The price cap changes every three months, so the headline rate moves through the year. You can check the current unit rate for your region on the Ofgem price cap page before working out your own cost per charge.
How much can you save with an off peak EV tariff?
An off peak EV tariff is where the real savings sit. Intelligent Octopus Go charges from around 8p per kWh overnight, roughly a third of the standard cap rate. On a rate like that, a full 64kWh battery costs about £5 rather than £17, and other overnight household use benefits too.
Rates vary by supplier and region, and some drivers on fixed regional deals pay even less. Zapmap puts the typical dedicated EV tariff at around 8.8p per kWh. To access these rates you usually need a smart meter and, for the smartest tariffs, a compatible car or home charger.
The catch is that daytime electricity on these tariffs usually costs a little more than the standard cap. They work best when you can shift most of your charging, and ideally your washing and other heavy use, into the cheap overnight window.
How much does public EV charging cost?
Public charging costs far more than charging at home. In June 2026, Zapmap put the weighted average pay-as-you-go price at 54p per kWh for slower chargers up to 49kW, and 79p per kWh for rapid and ultra-rapid chargers of 50kW and above, the ones drivers rely on for longer journeys.
Prices vary widely between networks. Across the main rapid and ultra rapid operators, pay-as-you-go rates ranged from about 61p per kWh at the cheapest to 92p per kWh at the most expensive in June 2026. Memberships, subscriptions and off-peak network deals can bring these figures down.
On a 79p per kWh rapid charger, topping a 64kWh family car up from 10% to 80% costs around £40 and adds roughly 170 miles of range. You can track live network averages on the Zapmap price index and the RAC Charge Watch.
Why is public charging so much more expensive than home charging?
Two things drive the gap. The first is tax. Electricity used at home carries 5% VAT, but electricity from a public charger carries the full 20% rate. That difference alone adds a significant premium for drivers who cannot charge on a driveway.
The second is infrastructure. Charging networks pay heavily for grid connections, high-powered equipment and site upgrades, and those costs are built into the price per kWh. The actual electricity is only a small part of what you pay at a rapid charger.
Campaigners, including the FairCharge campaign backed by the RAC, argue that the 20% rate is unfair on drivers without home charging and want public charging cut to 5% to match domestic electricity. Until any change happens, the home to public gap remains wide.
What is the cost of charging an electric vehicle per mile?
Cost per mile is the clearest way to compare charging options and to judge the charging EV price against petrol. On the standard home cap, an efficient EV costs around 7p to 8p per mile. On an off-peak overnight tariff, that falls to roughly 2p per mile.
Public charging is a different picture. Zapmap figures put slower public charging at about 16p per mile and rapid or ultra-rapid charging at around 24p per mile in June 2026. A petrol car doing 40 miles per gallon typically costs somewhere between 15p and 19p per mile, depending on pump prices.
So home charging is a fraction of the cost of petrol, while relying solely on public rapid chargers costs broadly the same as fuelling a petrol car. The savings from going electric depend heavily on how much of your charging you can do at home.
What affects the cost of charging an electric vehicle?
Several factors change what you pay. Battery size sets the total energy needed, so a small 40kWh city car costs far less to fill than a 90kWh SUV. Your electricity rate or the network price then multiplies that energy figure into a pounds and pence cost.
- Where you charge: home, an off-peak tariff, a slower public unit or a rapid charger, each at a very different price per kWh.
- Time of day: overnight EV tariffs and some network off-peak windows are much cheaper than peak rates.
- Battery size and state of charge: larger batteries and emptier starting points mean more energy and higher cost per session.
- Vehicle efficiency: a car that returns more miles per kWh costs less to run, and cold weather or high speeds reduce that efficiency.
- Memberships and subscriptions: network plans and cards can cut the pay-as-you-go rate on public chargers.
What does EV charging cost mean for transport operators and fleets?
For operators moving to electric minibuses or accessible vehicles, the same rules apply at a larger scale. Depot charging on an off-peak tariff overnight is the equivalent of home charging, and it is where the running cost case for electric fleets is strongest.
The risk is unplanned public rapid charging, which can quietly erode any saving. Understanding your cost per mile, matching vehicle range to routes and scheduling charging around cheap overnight windows all protect the budget. Route planning that avoids unnecessary mileage cuts energy costs and emissions whatever a vehicle runs on.
Road XS helps transport operators plan efficient routes and keep tight control of vehicle use, which feeds directly into lower energy costs as fleets electrify. If you are weighing up the move to electric vehicles, we can help you plan around it.
Frequently asked questions
How much does it cost to fully charge an electric car in the UK?
A full charge of a typical 64kWh battery costs around £17 at home on the standard price cap of 26.11p per kWh. On an off-peak EV tariff at around 8p per kWh, it falls to about £5, while a public rapid charge can cost roughly £40.
Is it cheaper to charge an EV at home or in public?
Home charging is far cheaper. The standard home rate is 26.11p per kWh and a dedicated overnight EV tariff can be around 8p per kWh. Public rapid charging averaged about 79p per kWh in June 2026, so charging at home can cost less than a tenth of a public rapid charge.
How much does it cost to charge an EV per mile?
An efficient EV costs around 7p to 8p per mile on the standard home cap and roughly 2p per mile on an off-peak overnight tariff. Public rapid charging costs about 24p per mile, broadly comparable to a petrol car at 40 miles per gallon.
Why do public chargers cost more than charging at home?
Public charging carries 20% VAT compared with 5% on home electricity, and networks build the cost of grid connections and high-powered equipment into their prices. Together these push public rates well above the home cap.
What is the cheapest way to charge an electric vehicle?
The cheapest way is charging at home overnight on a dedicated off-peak EV tariff, often around 8p per kWh. Pairing that with a smart charger, and where possible solar generation, drives the cost per mile down to a few pence.
How much does rapid charging cost in 2026?
In June 2026, the weighted average pay-as-you-go price for rapid and ultra-rapid charging was about 79p per kWh, with the main networks ranging from around 61p to 92p per kWh. A 10% to 80% top-up of a family car costs roughly £40.
Do you pay VAT on EV charging?
Yes. Electricity used to charge at home is taxed at 5% VAT, the same as the rest of your household electricity. Charging at a public charge point is taxed at the full 20% rate, which is one reason public charging costs more.
