Quick answer

Between £4 and £25 for a full charge depending on where and when. Home charging on Octopus Intelligent Go off-peak (7p per kWh) costs around £4 to £5 for a full 60kWh charge. Standard home tariff (25p per kWh) costs around £15. Public rapid chargers (60 to 80p per kWh) cost £36 to £48 for the same energy. Most UK EV owners do most charging at home overnight on cheap rates. Public rapid is for long journeys only.

£460kWh

Off-Peak Home Charge

Full 60kWh charge on Octopus Intelligent Go (7p per kWh) costs around £4. The cheapest UK EV charging available.

£1560kWh

Standard Home Tariff

Full 60kWh charge on standard variable tariff (25p per kWh) costs around £15. Still much cheaper than petrol.

£4260kWh

Public Rapid Charge

Same 60kWh charge on UK public rapid charger (70p per kWh) costs around £42. Comparable to or above petrol per mile.

2p/mile

Off-Peak Per Mile

Off-peak home charging works out to around 2p per mile vs 16p for petrol. The cost case for home-charged EVs is overwhelming.

What it actually costs to charge a UK electric car

UK EV charging cost varies wildly between cheapest and most expensive options. The right charging strategy can mean the difference between paying 2p per mile or 22p per mile for the same EV. Knowing where and when to charge is the single biggest cost variable in EV ownership.

Home charging cost

Home is by far the cheapest place to charge for UK EV owners. The cost depends on your electricity tariff. On a smart EV tariff like Octopus Intelligent Go, the off-peak rate is around 7p per kWh between 11.30pm and 5.30am. A full 60kWh charge costs around £4. On a standard variable tariff at 25p per kWh, the same charge costs £15.

The off-peak vs standard difference is huge. A typical UK driver doing 10,000 miles per year uses around 2,800 kWh of electricity for charging. On Octopus Intelligent Go that costs around £200 per year. On standard variable that costs around £700 per year. Smart tariff switching is worth £400 to £500 annually for typical UK EV drivers.

Public charging cost

Public chargers cost more because they have to cover infrastructure capital, maintenance and grid connection costs. Slow public chargers (3 to 7kW) at supermarkets and car parks typically cost 30 to 50p per kWh. Some are free for the duration of a shopping visit. Fast public chargers (22kW) at workplaces and destination charging cost 35 to 55p per kWh.

Rapid chargers (50 to 150kW) at motorway services cost 60 to 80p per kWh. Ultra-rapid chargers (150 to 350kW) at the newest UK hubs cost 70 to 85p per kWh. The price reflects the value of speed when on a long journey but the per-mile cost is similar to or above petrol.

The strategic split

Most UK EV owners do 80 to 90 percent of charging at home and 10 to 20 percent at public rapid chargers on long journeys. Home charging dominates the per-mile cost calculation. A driver who does mostly home charging averages 3 to 4p per mile in energy cost. A driver who does mostly public rapid charging averages 17 to 22p per mile. Home access genuinely transforms the running cost case.

Workplace and free charging

Some UK employers offer free or low-cost workplace charging as a benefit for EV-driving employees. UK supermarket chains (Tesco/Volta, Sainsbury's, Lidl) and some shopping centres offer free slow charging during your visit. These options further reduce the average cost per mile if you can plan around them. Check availability in your area.

Authoritative context

UK electricity tariff rates are regulated by Ofgem under the standard market rules. Octopus Intelligent Go and similar smart EV tariffs operate within the broader UK supply market with prices reviewed periodically. Public charging prices are unregulated and set by individual operators (Gridserve, IONITY, BP Pulse, Tesla Supercharger, ChargePoint). Zap-Map and the National Chargepoint Registry track UK public charging pricing. The Office for Zero Emission Vehicles (OZEV) publishes ongoing UK EV charging market analysis. Comparison sites including Money Saving Expert and What Car? provide regular tariff and charging cost comparisons.

Typical UK EV owner charging cost split

1

Home charging (80 to 90 percent of energy)

Bulk of UK EV charging happens at home overnight. Off-peak tariff makes this 2 to 3p per mile cost.

2

Workplace charging (5 to 10 percent)

Some UK employers offer free or low-cost charging. Adds another cheap option for daytime topping up.

3

Long-journey rapid (5 to 15 percent)

On road trips drivers use public rapid chargers. 30 to 45 minute stops at 60 to 85p per kWh.

4

Average annual cost

Typical UK driver: £200 to £400 per year on smart tariff with mostly home charging. £700 to £1,400 on standard tariff or heavy public use.

Key UK EV charging cost facts

Smart tariff is the win

Switching from standard variable to Octopus Intelligent Go saves £400 to £500 per year for typical UK EV drivers. Single biggest cost lever.

Public rapid is expensive

UK public rapid chargers cost 60 to 85p per kWh. Per-mile cost similar to petrol. Use only when needed for long journeys.

Home is cheapest

Home overnight charging on smart tariff costs around 2p per mile. Petrol equivalent costs around 16p per mile. 8x difference.

Free options exist

Some UK supermarkets, workplaces and destinations offer free slow charging. Worth tracking in your area to reduce overall cost.

Petrol fuelling cost

  • 16p per mile typical (45 mpg petrol)
  • Per full tank: ~£75
  • Annual cost (10k mi): ~£1,600
  • All fuel pumps similar price
  • No off-peak option
  • Predictable but not cheap

EV charging cost

  • 2p per mile (home off-peak)
  • Per full charge: £4 to £15 home
  • Annual cost (10k mi): £200 to £400 home
  • Public rapid: £42+ for same energy
  • Smart tariff dramatically cheaper
  • Wide variation by tariff and location

Charging cost is the biggest reason UK drivers switch to EVs. The wider EV Charger Guidance hub covers home charger install, the buying decision, battery questions and the practical questions UK drivers ask before switching from petrol.

Frequently asked

Common questions

What is the cheapest way to charge a UK EV?
Octopus Intelligent Go or similar smart EV tariff with off-peak rate around 7p per kWh and home wallbox. A full 60kWh charge costs around £4. Annual cost for a typical UK driver is around £200 to £400. No other UK option matches this for routine charging. Solar PV with battery can theoretically charge for less if your panels generate enough surplus during charging hours.
Can I charge my EV for free?
Sometimes. UK supermarket chains (Tesco/Volta, Sainsbury's, Lidl) offer free slow charging at some stores. UK shopping centres often have free first-hour charging. Some workplaces offer free charging as an employee benefit. Hotel chains (Premier Inn, Travelodge) often have free overnight charging for guests. These free options can reduce your average per-mile cost meaningfully if you plan around them.
Why is rapid charging so expensive?
Three reasons. Capital cost of rapid charger units (£40,000 to £100,000 each). Grid connection costs (high-power three-phase supplies are expensive to provision). Real estate cost at motorway services. Rapid chargers also have lower utilisation rates than fuel pumps so the per-charge price has to recover infrastructure costs over fewer charges. The 60 to 85p per kWh price reflects all of this.
Should I install solar panels for my EV?
Worth considering for long-term UK EV owners. UK solar PV systems pay back in 8 to 12 years on average. Combined with battery storage, you can charge your EV largely from solar surplus during the day. Smart chargers like the MyEnergi Zappi divert solar surplus directly to the EV. The total solar with battery and EV charger install costs £8,000 to £15,000 but eliminates most ongoing electricity bills.
How much does charging cost during a road trip?
Depends on charger choice. UK motorway service rapid chargers cost 60 to 85p per kWh. A 200-mile motorway trip in a typical EV uses around 60 kWh, which means around £36 to £51 in charging cost. The same trip in a petrol car at 45 mpg with petrol at £1.45 per litre costs around £29. EV charging cost on long journeys is similar to or slightly above petrol when public rapid is the only option.
