How Much Does It Cost to Charge an Electric Car in the UK?

Charging an electric car at home costs roughly 8.5p per kWh on an off-peak tariff, while a public rapid charger averages 76p per kWh. That's a nine-fold difference for the same electricity. The Zapmap Price Index shows drivers who charge mostly at home spend around 5p per mile, compared to 23p per mile on the rapid network (Zapmap, 2026). Knowing where and when to plug in can save you over £700 a year.

This guide breaks down exactly what you'll pay for every type of EV charging in the UK right now, from a three-pin plug at home to a 350kW ultra-rapid hub on the motorway.

Key Takeaways

• Home charging on an off-peak EV tariff costs around 8.5p per kWh, or roughly 2.5p per mile.
• The Ofgem price cap sets standard home electricity at 24.67p per kWh from April 2026 (Ofgem, 2026).
• Public rapid and ultra-rapid chargers average 76p per kWh pay-as-you-go (Zapmap, 2026).
• The UK now has 118,321 public EV chargers across 45,561 locations (Zapmap, 2026).
• Drivers who charge at home save £720 per year compared to petrol equivalents (Zapmap, 2026).

What Does Home Charging Actually Cost?

Home charging is by far the cheapest way to run an EV. The Ofgem energy price cap sets the standard electricity rate at 24.67p per kWh from April 2026 (Ofgem, 2026). For a typical EV with a 60kWh battery, a full charge from empty costs about £14.80 at that rate. That gives you roughly 200 miles of range, working out at around 7p per mile.

But most EV drivers don't pay the standard rate. Dedicated EV tariffs from suppliers like Octopus Energy, OVO, and British Gas offer off-peak overnight rates between 7p and 9p per kWh. Charging a 60kWh battery overnight on one of these tariffs costs just £5.10, or about 2.5p per mile.

Three-pin plug vs dedicated wallbox

You can plug any EV into a standard three-pin socket. It works, but it's slow. A three-pin plug delivers around 2.3kW, meaning a 60kWh battery takes over 26 hours from empty. It also isn't designed for sustained high loads, so there's a small fire risk over long periods.

A dedicated 7kW home wallbox cuts that charge time to about 8.5 hours. That fits neatly into an overnight charge window. Installation costs between £800 and £1,200 including the unit, though the OZEV grant can knock off up to £350 for eligible households (GOV.UK, 2025).

How much does solar charging save?

If you have solar panels, the effective cost drops to zero once the panels are paid off. Even before that, surplus solar generation that would otherwise be exported at 4-6p per kWh through the Smart Export Guarantee (Ofgem, 2025) is worth far more when stored in your car's battery than sold back to the grid.

How Much Do Public Chargers Cost?

Public charging prices vary wildly depending on the charger speed and network. The Zapmap Price Index tracks nearly four million charge sessions per month and reports a weighted average pay-as-you-go (PAYG) price of 54p per kWh on standard chargers (3-49kW) and 76p per kWh on rapid and ultra-rapid chargers (50kW and above) as of February 2026 (Zapmap, 2026).

Here's what you'll pay at different speeds:

These are PAYG prices. Subscription plans and network memberships usually bring costs down by 10-20%. Tesla Superchargers, for example, charge non-Tesla drivers an average of 56p per kWh, while Tesla owners pay around 40p per kWh (Zapmap, 2026).

Which networks are cheapest?

Prices differ significantly between operators. At the budget end, Sainsbury's Smart Charge offers rapid charging at 72p per kWh, while Believ charges 66p per kWh. Tesla Superchargers open to all drivers average 56p per kWh (Zapmap, 2026).

At the premium end, motorway service area chargers from networks like Gridserve or BP Pulse can exceed 80p per kWh. The convenience premium mirrors what happens with petrol stations on motorways.

Is It Cheaper to Charge an EV or Fill Up with Petrol?

For most drivers, charging an EV is significantly cheaper than filling up with petrol. Zapmap's driver profiles show that a household charging mostly at home on an off-peak tariff saves around £720 per year compared to running an equivalent petrol car (Zapmap, 2026). Even a mixed-charging driver who splits between home and public rapid chargers saves about £290 annually.

Here's the per-mile breakdown:

The crossover point matters. If you rely entirely on public rapid chargers, the per-mile cost of an EV (23p) exceeds petrol (15p). But the vast majority of EV drivers don't do that. The Zapmap Annual Survey found that 80% of EV charging happens at home or at work (Zapmap, 2025). For those drivers, the fuel cost savings are clear.

There are also running cost savings beyond fuel. EVs pay zero road tax (VED) until April 2025, and from then still pay reduced rates. Servicing costs are lower because there's no engine oil, fewer brake pad changes (regenerative braking does most of the work), and no clutch, exhaust, or timing belt to replace.

How Fast Is the UK Charging Network Growing?

The UK's public charging infrastructure has expanded rapidly. There are now 118,321 EV chargers across 45,561 locations (Zapmap, 2026). In February 2026 alone, 1,592 new chargers were added to the network.

The biggest growth is in ultra-rapid charging. In 2025, 3,425 ultra-rapid chargers (150kW+) were added, a 40% year-on-year increase (Zapmap, 2026). These chargers can add 100 miles of range in around 10 minutes, making long-distance EV travel far more practical than it was even two years ago.

Charging hubs are replacing single chargers

The trend is shifting from scattered individual chargers to dedicated charging hubs. At the end of February 2026, there were 958 rapid charging hubs across the UK (locations with eight or more rapid or ultra-rapid chargers), up 28% from 723 at the end of 2024 (Zapmap, 2026).

These hubs reduce the anxiety of turning up to a single charger and finding it occupied or broken. With eight or more chargers at one location, the chances of queueing drop significantly.

Regional gaps remain

Coverage isn't even across the country. Greater London leads with 30,614 chargers, followed by the South East with 15,368 and Scotland with 12,609 (Zapmap, 2026). Northern Ireland has just 354 rapid or ultra-rapid chargers, and the North East has 857. If you live in these regions, planning your charging stops in advance matters more.

What About Workplace Charging?

Workplace charging sits in a sweet spot between home and public costs. Many employers offer free or subsidised charging as a staff perk. Even when charged at cost, workplace chargers typically run at the commercial electricity rate (15-20p per kWh), which is cheaper than any public charger.

The UK government's Workplace Charging Scheme (WCS) provides eligible businesses with up to £350 per socket towards the cost of installing chargers, covering up to 40 sockets per applicant (GOV.UK, 2025). This has accelerated the rollout of office and depot charging.

If your employer offers charging, even at a small fee, it's likely your second-cheapest option after home. It also means your car charges while you work, so you arrive home with a full battery.

How Can You Cut Your EV Charging Costs?

Regardless of your situation, there are practical steps to reduce what you spend on charging.

1. Switch to a dedicated EV tariff

Off-peak rates of 7-9p per kWh from EV-specific tariffs are less than a third of the standard cap rate. If you can schedule charging overnight, this is the single biggest saving available. Even without a home charger, some tariffs apply the off-peak rate to all overnight electricity, so your fridge and heating benefit too.

2. Use slower public chargers when you have time

Standard chargers (3-22kW) cost 54p per kWh on average, while rapid chargers cost 76p per kWh (Zapmap, 2026). If you're parked at a supermarket for an hour, a standard charger adds 7-22kWh for around £4-12. That's cheaper per kWh than a 10-minute rapid session.

3. Join network subscription plans

Networks like BP Pulse, Osprey, and Tesla offer membership or subscription deals that cut the per-kWh rate. If you regularly use one network, the subscription often pays for itself within a few sessions.

4. Avoid motorway rapid chargers when possible

Just like motorway petrol stations, motorway chargers charge a premium. Planning a stop just off the motorway at a retail park or supermarket charger can save 10-15p per kWh.

5. Check PetrolPal before every charge

PetrolPal's EV charger finder shows all nearby chargers with their speeds, connector types, and networks. Sort by what matters to you and avoid paying more than you need to.

How Are BEV Sales Shaping the Market?

Battery electric vehicle (BEV) registrations reached 51,494 in the first two months of 2026, holding a 22% market share (SMMT, 2026). When you add plug-in hybrids (12.4% share) and conventional hybrids (13.3%), electrified vehicles now account for nearly half of all new car sales.

Used BEV sales are growing even faster. In 2025, 274,815 used battery electric cars changed hands, up 45.7% on the previous year (SMMT, 2026). Falling used EV prices mean that electric motoring isn't just for new-car buyers anymore.

This growth is driving competition between charging networks, which benefits drivers. More chargers, more hubs, and more competitive pricing are all direct results of rising EV adoption.

Frequently Asked Questions

How much does it cost to charge an electric car at home in the UK?

At the Ofgem price cap rate of 24.67p per kWh from April 2026, a full charge of a typical 60kWh EV battery costs about £14.80 (Ofgem, 2026). On a dedicated off-peak EV tariff at 8.5p per kWh, the same charge costs around £5.10.

How much does rapid charging cost in the UK?

The average pay-as-you-go price at rapid and ultra-rapid public chargers (50kW+) is 76p per kWh as of February 2026 (Zapmap, 2026). That works out to about 23p per mile for an average-efficiency EV.

Is it cheaper to charge an EV or buy petrol?

For drivers who charge at home, an EV costs 2.5-7p per mile compared to about 15p per mile for petrol. If you rely entirely on public rapid chargers, the EV cost rises to 23p per mile, which is more expensive than petrol (Zapmap, 2026).

How many public EV chargers are there in the UK?

As of February 2026, the UK has 118,321 public EV chargers across 45,561 locations. Of those, 27,009 are rapid or ultra-rapid chargers across 6,727 locations (Zapmap, 2026).

How long does it take to charge an electric car?

It depends on the charger speed. A 7kW home wallbox fills a 60kWh battery in about 8.5 hours. A 50kW rapid charger takes around 70 minutes. A 150kW+ ultra-rapid charger can add 100 miles of range in roughly 10 minutes (Zapmap, 2026).

The Bottom Line

EV charging costs vary enormously depending on where and when you plug in. Home charging on an off-peak tariff remains the cheapest option at around 2.5p per mile, saving over £700 a year compared to petrol. Public rapid charging is convenient but expensive at 76p per kWh. The best strategy for most drivers is to charge at home overnight for daily use and rely on public chargers only for longer trips.
