Pricing
What does public charging actually cost?
There is no single price. The same physical charger will bill you differently depending on how you authenticate, and the spread is large enough to change where you stop.
Why there is no single price
A public charging session involves at least three parties: the operator who owns the hardware, the mobility service provider whose card or app you used, and any roaming platform between them. Each takes a margin, and the total depends on which chain you happened to use.
The result is genuinely confusing. Presenting an operator app, a third-party roaming card and a contactless bank card at the same charger can produce three different prices, sometimes differing by more than a factor of two.
| Model | Typical structure | Watch for |
|---|---|---|
| Direct contactless | Per kWh, highest rate | Convenience premium |
| Operator subscription | Monthly fee plus lower per-kWh | Only worth it if you use that network often |
| Roaming card | Per kWh plus a roaming margin | Margin varies by operator and country |
| Per-minute pricing | Billed on time, not energy | Punishes slow-charging cars and cold packs badly |
| Idle fee | Per minute after charging completes | The most common unexpected charge |
The per-minute row deserves attention. If a network bills by time and your car charges slowly — because it is cold, or because you are above 80% — you pay for the taper. See our charge curve explainer.
Charging tariff structures
Common questions
Is a subscription worth it?
Only if you regularly use that specific network. For occasional long trips, roaming or direct payment usually costs less overall.
Why did the same charger cost more this time?
Is public charging more expensive than petrol?
At the most expensive rapid networks it can approach it. On home overnight tariffs it is far cheaper. That gap is the single biggest variable in EV running cost.
How do I avoid idle fees?
Set an alarm, and prefer stops where you can see the car. Our motorway food site covers where those are.
