How much does it cost to charge an electric car in Luxembourg in 2026?

Charging an electric car at home in Luxembourg costs about €0.19 per kWh at night and €0.20 during the day in 2026, so roughly €10 to fill a 50 kWh battery and about €3.40 per 100 km. On the public Chargy and SuperChargy network, the same energy costs two to three times more.

This guide sets out what a charge really costs by location, battery size and annual mileage, gives you a formula to work out your own figure, and shows what a year of charging costs for a company car, including for cross-border drivers who live in Belgium or Germany. Voltaback measures and reimburses home charging for more than 200 companies at each driver's own contract price, which is why we track these numbers closely.

The right number: the price of a charged kWh, not the average bill

You will often read that electricity costs about €0.26 per kWh in Luxembourg. That figure is the average bill price for a household using 3,900 kWh a year, fixed charges included (network subscription, metering). It does not tell you what one extra kWh costs, which is what you add when you plug in the car.

That marginal kWh has three parts:

• energy, billed by your supplier (Enovos, Sudstroum, Leo, Nordenergie, Steinergy and others);
• the volumetric network fee charged by Creos, €0.0510 per kWh excluding VAT in 2026;
• 8 % VAT. The electricity tax and the compensation mechanism practically cancel each other out for households in 2026.

On Enovos's dual-rate "Naturstroum Home Double" offer (€0.12243 at night and €0.13473 during the day, excluding VAT), that gives about €0.19 at night and €0.20 during the day, VAT included. Your monthly fixed charges do not change when you charge, so they are not part of the cost of charging. Sources: Le Quotidien, 2026 electricity bill, Switchr, Creos network tariff 2026.

Each component is broken down, supplier by supplier, in our article on the electricity price in Luxembourg.

What does a full charge cost for your car?

No charge reaches the battery without losses: the on-board charger, the cable and the battery all warm up. When charging at home on AC, allow for about 10 % losses. To store 50 kWh, your meter records roughly 55.

In practice, hardly anyone charges from 0 to 100 %. Most drivers plug in in the evening and top up from around 20 to 80 %, so a daily charge costs a few euros. How long that takes on a socket or wallbox is covered in our article on EV charging time.

And a plug-in hybrid?

A plug-in hybrid usually has a usable battery of 15 to 25 kWh. A full charge at home then costs about €3.50 to €5, for 50 to 80 km of electric range in daily driving. That is only cheap if the hybrid really is charged every evening; otherwise it runs on petrol.

Cost per 100 km: official figures, real driving and winter

Cost per 100 km is the easiest way to compare with a tank of fuel. It depends on real consumption, which is not what the brochure says.

WLTP versus real consumption

WLTP consumption is a laboratory type-approval figure. In Luxembourg it also sets the benefit-in-kind rate of an electric company car (0.5 % or 0.6 % of the list price). On the road, a compact car uses more like 16 to 20 kWh per 100 km, charging losses included, depending on speed and terrain.

The winter effect

In cold weather, heating the cabin and the battery pushes consumption up, often by around 20 to 30 % on short trips. A commute that costs €3.40 per 100 km in summer can reach about €4.20 in January. Pre-heating the car while it is still plugged in limits the effect.

Electric or diesel: the cost of 100 km

A compact diesel using a real 6 litres per 100 km costs about €12.30 per 100 km, at a diesel price of around €2.05 a litre (national average at the end of October 2026). The electric car charged at home at night costs about €3.40, roughly a quarter. Even on SuperChargy, at about €11.35, it stays just below diesel. Diesel price source: fuel-prices.eu, Luxembourg, week of 19 to 26 October 2026.

What does charging cost per month and per year?

Monthly cost depends mostly on mileage. At 18 kWh per 100 km at the meter and about €0.19 per kWh at night in Luxembourg:

This amount never appears separately on the electricity bill: it disappears into the household's total consumption, which is exactly what makes reimbursing a company car without measurement so difficult.

Work out your own cost in three steps

Your price is not your neighbour's: it depends on your supplier, your offer and when you charge. Here is the method.

1. Find your price per kWh on your bill or contract: energy price excluding VAT, plus the €0.0510 Creos network fee, all multiplied by 1.08 for VAT.
2. Estimate the kWh at the meter: kWh added to the battery (shown in the car's app) divided by 0.9 to account for losses.
3. Multiply: kWh at the meter x price per kWh = cost of the charge.

Example: you add 30 kWh to the battery. At the meter that is 30 / 0.9 = 33.3 kWh. At €0.19, the charge costs €6.33.

For a whole fleet, the home charging cost simulator runs this calculation with your company's mileage and vehicle mix.

The hidden cost: Creos reference power

Since 1 January 2025, Luxembourg's network tariff has been built around a reference power: a threshold in kW (3, 7, 12 kW and so on) assigned to each household from its last 12 months of consumption and recalculated every month. The Smarty meter records average power in 15-minute intervals.

Every kWh drawn above that threshold carries an overrun surcharge of €0.0765 excluding VAT. A kWh charged at night then goes from about €0.19 to about €0.27. An 11 kW wallbox in a household with a 3 kW reference power puts most of the charge into overrun.

Two habits avoid the surcharge:

• limit the charging power (3.7 to 7 kW is enough overnight) and spread the charge;
• simulate the effect of a wallbox on the myCreos portal, which offers standard load curves for "electric car with or without power reduction".

Moving from a 3 kW to a 7 kW reference power adds about €65 a year to the fixed fee, excluding VAT. Paying the overrun on 4,500 kWh of charging a year would cost around €370 including VAT. The choice is easy. Source: Creos, guide to the 2026 tariff structure.

To schedule charging at the right times and stay below the threshold, see our guide to charging your EV at night.

Dynamic tariffs and solar: charging for even less

Luxembourg shares a wholesale price zone with Germany. With a dynamic tariff, such as Enovos's "dynamic naturstroum", the energy price follows the zone's hourly market price plus a margin; the network fee and VAT are added as usual. It requires a Smarty meter, which more than 98 % of households now have. At night and on sunny or windy days the market price is often well below a fixed price, while on winter evenings it can be higher. A car that charges in the cheap hours, through its app or a wallbox, captures exactly that swing. Source: Switchr, dynamic tariffs in Luxembourg.

With your own solar panels, the marginal cost falls further during the day: every kWh you consume yourself replaces a kWh you would have bought. It pays off mainly on home-office days, when the car is parked at home at midday.

For a company car, both mean the kWh price is no longer a single figure but changes hour by hour. A reimbursement meant to reflect each driver's real price has to take this into account, or the car policy needs a clear rule.

What does a year of charging cost a cross-border worker?

On 31 March 2026, 49 % of employees in Luxembourg were cross-border workers. Their cars spend the night in Belgium, Germany or France and charge at their home country's electricity price. Source: IGSS, employment dashboard, March 2026.

Take a typical cross-border commute: 25,000 km a year, 18 kWh per 100 km at the meter, so 4,500 kWh a year charged at home.

For the same commute, a driver living in Germany pays more than €50 a month more than a Luxembourg resident. Reimbursing at a Luxembourg price, or at a country average set by a leasing company, leaves many cross-border drivers out of pocket.

What holds everywhere: charging at home costs two to three times less than the public network. Everything a cross-border driver needs to know about home charging is in our company car driver's guide.

Charging at work: often free, but no dedicated tax rule

Many Luxembourg employers offer chargers in their car park. According to the 2026 Arval barometer, 86 % of companies in Luxembourg have or plan on-site charging, against 21 % for home charging. Source: Paperjam, October 2026.

For the driver, charging at the office is often free. Two points to keep apart:

• company car: electricity is a running cost of the car, just like fuel;
• private car: Luxembourg has no rule that explicitly exempts free charging of an employee's own car at work. An employer planning to offer it widely should check the treatment with its fiduciary.

Public charging: Chargy, SuperChargy and Electra

The national public network has two families of chargers: Chargy (accelerated AC charging, up to 22 kW) and SuperChargy (DC fast charging). Since the end of 2025 the network has been run by a concession holder, and the price depends on the mobility service provider you use to start the session (card, app or direct payment).

As an order of magnitude, tariffs recorded since March 2025 were €0.49 per kWh on Chargy and €0.63 on SuperChargy. Idle fees may apply. The government recommends comparing offers with the Klima-Agence's free Chargecheck tool. Sources: Luxtoday, charging in Luxembourg, Chamber of Deputies, answer to parliamentary question no. 4477, August 2026.

Other fast-charging networks set their own prices: Bestcharge, for example, lowered its DC rate from €0.69 to €0.53 per kWh including VAT on 1 July 2026 (Paperjam).

Electra's ultra-fast stations, in Luxembourg since the Capellen site opened in March 2025, charge about €0.59 per kWh including VAT through the app and €0.69 by bank card at the charger. Sources: Electra, charging tariffs, Paperjam, Capellen opening.

For long business trips, the Electra charging card offered by Voltaback complements home charging, with central invoicing for the company.

Company cars: what charging costs the business

For a company car covering 25,000 km a year, home charging costs the company between €850 and €1,500 a year depending on where the driver lives. On the public network, the same energy would cost over €2,200. Energy therefore weighs far less in a vehicle's total cost than with a petrol or diesel car, as our analysis of fleet total cost of ownership shows.

Example: charging budget for 30 company cars

A company with 30 electric company cars, each covering 25,000 km a year and charging 4,500 kWh at home, with 10 drivers living in Luxembourg, 10 in Germany and 10 in Belgium on a dual-rate meter:

A single Luxembourg price would under-reimburse the 20 cross-border drivers by about €8,100 a year in total, the German residents alone by about €585 each. Conversely, a generous flat amount for everyone overpays Luxembourg residents, and the surplus would be salary.

How charging is reimbursed

No Luxembourg text sets an official flat rate per kWh. In practice, following the logic of the Grand-Ducal Regulation of 23 December 2016, electricity for a company car is a running cost of the car, covered by the flat-rate benefit in kind (0.5 % or 0.6 % of the list price per month for an EV), provided the company reimburses the real cost of the kWh actually charged. Anything above the real cost would be salary. The ACD has not published a position on this reading, so have it confirmed by your fiduciary. Sources: Klima-Agence, benefits in kind, Guichet.lu, company car.

That is why measurement matters. Voltaback connects to the car (more than 48 brands) with no box or hardware, counts the kWh actually charged at home and applies each driver's contract price. Voltaback relies on the home's MID-certified meter, not on a standalone cable meter. The measurement has been audited by an independent third party, with a relative error of 1.22 %, and the company never receives drivers' location data. See how it works on the home charging reimbursement page.

Reimburse every kWh at its real price

Charging at home is by far the cheapest way to drive electric in Luxembourg. For the company, the only tricky part is paying each driver, resident or cross-border, the right amount, without a rough flat rate or expense claims.
