Home charging: how much your fleet can save
Charging a fleet vehicle at home costs about half as much as public charging, in Luxembourg and for cross-border workers alike. Shifting part of it to home charging directly cuts TCO.

Questions and answers
Understanding the calculation
At home, a kWh costs around €0.26 to €0.28 in Luxembourg in 2026, less with a night tariff. Charging a 50 kWh battery therefore costs around €13 to €14. It is by far the cheapest option, ahead of public fast charging.
At home, budget around €5 per 100 km in Luxembourg (about 18 kWh at €0.27), and just over €6.50 for a cross-border worker living in Belgium or Germany. With public fast charging, it is often €9 or more. The calculator above adjusts this to your actual consumption.
Around €0.26 to €0.28/kWh all-in in Luxembourg in 2026, thanks to state support on grid costs, often less with a night tariff or a dynamic tariff. For cross-border workers, around €0.36/kWh in Belgium and €0.38/kWh in Germany. Compare with around €0.25 at a company charger and €0.50 or more for public fast charging.
Yes, on the energy line: it is a recurring gain, separate from the hardware investment. In Luxembourg, only 21 % of companies use or plan home charging in their charging policy, compared with 86 % for on-site charging (Arval Barometer 2026): there is still plenty of room.
On the energy line, shifting charging from public networks (€0.50 or more per kWh) to home (around €0.27/kWh in Luxembourg) roughly halves the cost of those kilometres. For a fleet of 100 vehicles at 30,000 km/year, that represents several tens of thousands of euros per year.
In Luxembourg, there is no regulated day/night tariff, but some suppliers offer a night tariff (around 25 to 30 % cheaper) or a dynamic tariff, often lower at night. A vehicle plugged in at home charges precisely at night: it benefits from the lowest price, without the driver doing anything.
Public fast charging ties up the driver for 20 to 30 minutes. If that time is usually productive, it has a cost, which the calculator can optionally value at the cost of one FTE (adjustable share lost). At home, the vehicle charges overnight, without tying up the driver.
Several solutions exist: connected charger, connected cable or tracking software, with very different costs once management is taken into account. The next calculator compares their annual cost.
Find out more: how much does it cost to charge an electric car at home?
In Luxembourg, charging an electric car at home costs around €0.26 to €0.28/kWh all-in in 2026, and less with a night tariff. For a cross-border worker, budget around €0.36/kWh in Belgium and €0.38/kWh in Germany. At a company charger, around €0.25. With public fast charging, the price often exceeds €0.50. The same vehicle can therefore cost twice as much depending on where it plugs in.
In terms of use, that is around €5 per 100 km at home in Luxembourg, compared with €9 or more for public fast charging. Home charging remains by far the cheapest option, even for a cross-border worker.
For a fleet, the stakes are high: in Luxembourg, home charging is still rarely part of fleet policies, and almost one employee in two is a cross-border worker, with a different kWh price depending on their country. Shifting more charging to home, while reimbursing each driver at their real price, lowers the bill every year. It is a direct, recurring TCO lever, with no hardware investment to pay off.
Methodology and sources
Sources and assumptions:
- Home electricity price in Luxembourg: around €0.26/kWh all-in in 2026 with state support (Statec), 26.7 to 28.0 c€/kWh depending on the offer; night tariffs and dynamic tariffs from some suppliers.
- Electricity price for cross-border workers: Eurostat averages (Belgium ≈ €0.36/kWh, Germany ≈ €0.38/kWh, first half of 2025).
- Share of cross-border workers in salaried employment (49 %): IGSS, March 2026.
- Home charging in company charging policies (21 %): Arval Barometer 2026.

Our kWh price assumptions for 2026
The calculator uses 2026 reference prices, which you can adjust. The kWh price varies widely depending on where you charge, which explains the difference in savings between home and public charging.
Charging location | kWh price 2026 | Cost per 100 km (18 kWh) |
|---|---|---|
Home, night tariff | ≈ €0.20 | about €3.60 |
Home, Luxembourg average price | ≈ €0.27 | about €4.86 |
Cross-border worker's home (Belgium, Germany) | ≈ €0.36 to €0.38 | €6.50 to €6.85 |
DC fast charger | €0.42 to €0.69 | €8 to €12 |
Ultra-fast charger (motorway) | about €0.79 | about €14 |

Fleet savings examples
Fleet of 50 vehicles, 25,000 km/year, 70 % home charging at night: the kWh cost gap between home and public charging represents several hundred euros per vehicle per year. Charging at home rather than on public networks roughly halves the energy cost.
Once the savings are quantified, the next step is to secure them: reimburse each driver at real cost, with a record per vehicle, without installing a charger. Have my savings validated by a Voltaback expert.
