What you pay per kWh depends far more on how a network structures its tariff, a subscription discount here, a connection fee there, per-minute billing past a threshold, than on any single headline price. Two stations a short walk apart can land on very different real costs for the same battery, even in 2026, because nothing forces them to charge the same.
Why prices aren't set once and left alone
Public charging isn't price-regulated the way household electricity often is. Each operator sets its own rate, its own fees, and its own subscription terms independently, based on its own costs: the electricity it buys, the equipment it installs, the real estate it rents, and how much competition sits nearby. That's structurally why comparing networks matters: there is no single "the price", only a set of prices set by different businesses for different reasons.
AC and DC live on different tariffs
Slow AC charging and fast DC charging are usually priced separately, because the equipment behind them costs an operator very differently. A DC fast charger needs a much larger grid connection and cooling system than an AC one, so its price per kWh reflects that extra infrastructure. A cheap AC rate at a given network tells you nothing about what the same network charges on its DC chargers, and checking one instead of the other is a common way drivers get surprised by a bill.
The spread is wide, and that's the point
It isn't unusual to find a station charging under €0.30 per kWh a short distance from one charging well over €0.60, once you account for every fee each one adds. That spread, not any single average, is what makes comparing before you plug in worth the ten seconds it takes.
Cheapest tends to be supermarket and local retail stations, mostly slow to standard charging, subsidised by the retailer's interest in keeping you parked and shopping. Mid-range covers regional networks and destination chargers with a more standard commercial pricing model. Most expensive tends to be premium ultra-fast networks along major routes, where captive demand and heavy DC infrastructure both push the price up.
Work out what you're really paying
The sticker price per kWh is only the start. Add any connection fee, any per-minute charge, and any idle fee to the energy cost, then divide by the kWh you actually took on. A 40 kWh charge at €0.45 per kWh with a €2 connection fee doesn't cost €18, it costs €20, an effective rate of €0.50. That five-cent difference is exactly the kind of gap that a quick comparison catches before you plug in, and it's the same gap that can separate one station from its cheaper neighbour.
The habit that actually saves money
Never plug in on reputation alone: a network you've used before isn't necessarily the cheapest one nearby today. A detour of a few hundred metres, checked before you commit rather than after, is routinely the difference between an average session and a cheap one. That comparison, station by station, real fee by real fee, is what goodcharge computes for you in real time.
