I'm going to give you the real figures. Not those from the manufacturer's press release, not those calculated using electricity at €0.10/kWh at night — a rate that no longer exists for most Belgians. The 2026 figures, with official CREG rates, real pump prices, and honest assumptions.
What are the official electricity rates for EVs in Belgium in 2026?
What is the real price per kWh to charge an EV at home in Belgium?
The CREG (Commission for the Regulation of Electricity and Gas) publishes all-in reference rates each quarter for the reimbursement of company car charging. These amounts reflect the real average price paid by Belgian households, including all charges: energy, distribution network, taxes, VAT.
CREG rates Q2 2026 (1 April — 30 June 2026):
| Region | CREG rate (all-in) |
|---|---|
| Flanders | €0.3191/kWh |
| Brussels | €0.3555/kWh |
| Wallonia | €0.3637/kWh |
This is your reference rate if you charge during the day without an optimised contract. With a dual-rate contract (day/night), the night rate can drop to €0.18–0.24/kWh depending on your supplier and region.
What changes in Wallonia from 1 January 2026. Wallonia's off-peak hours have changed schedule. Before 2026, weekends were entirely off-peak. This is no longer the case. From 1 January 2026, off-peak hours are 10 pm–7 am and 11 am–5 pm, seven days a week. Outside these windows — including Saturday morning or Sunday evening — you pay the full rate. If you charge at the weekend, plan between 11 am and 5 pm or at night to keep the dual-rate advantage.

What is the price of petrol and diesel in Belgium in 2026?
The price of SP95-E10 petrol hovers around €1.70 to €1.80/L in early 2026 (maximum legal price set by the FPS Economy). For diesel, expect €1.65 to €1.75/L.
I use €1.75/L as the reference for petrol and €1.70/L for diesel in the calculations below.
What do 100 km really cost in an EV versus a combustion engine car in Belgium?
What is the cost per 100 km for an EV charged at home in off-peak hours?
| Model | Real consumption | Daytime rate (Wallonia) | Optimised night rate |
|---|---|---|---|
| Dacia Spring | 14 kWh/100 km | €5.09 | €2.80 |
| Peugeot e-208 | 17 kWh/100 km | €6.18 | €3.40 |
| Hyundai Ioniq 6 | 17.5 kWh/100 km | €6.36 | €3.50 |
| Tesla Model Y | 20 kWh/100 km | €7.27 | €4.00 |
| Kia EV9 (7 seats) | 24 kWh/100 km | €8.73 | €4.80 |
Consumption in real mixed use (Belgian cycle), not WLTP.
What is the cost per 100 km for a combustion engine car at the pump in Belgium?
| Model | Real consumption | Fuel | Cost/100 km |
|---|---|---|---|
| Dacia Sandero | 6.0 L/100 km | Petrol | €10.50 |
| Peugeot 208 1.2 PureTech | 6.5 L/100 km | Petrol | €11.38 |
| Toyota Corolla 2.0 Hybrid | 4.8 L/100 km | Petrol | €8.40 |
| Volkswagen Passat TDI | 5.5 L/100 km | Diesel | €9.35 |
| Kia Sorento Diesel 7 seats | 7.0 L/100 km | Diesel | €11.90 |
What real saving does home charging represent over 15,000 km per year?
If you charge mainly at home overnight, the saving is real and significant. If you depend on public fast chargers, the calculation looks more like a diesel. That's the truth that brochures avoid.
Let's take a concrete case: a family car doing 15,000 km per year.
- Ioniq 6 charged at home overnight: 15,000 × 0.035 = €525/year in fuel
- Equivalent VW Passat TDI: 15,000 × 0.0935 = €1,403/year in fuel
- Saving on fuel alone: €878/year
Over 5 years, that's €4,390 difference on fuel alone. Add maintenance: no more oil changes, no more timing belt, no more particulate filter. Over the same period, count another €1,500 to €2,500 in savings depending on the models compared.
Are public chargers as economical as home charging?
These figures assume charging mainly at home. If you don't have a home charger — because you live in an apartment or regularly make long trips — the calculation changes completely.
| Charger type | Average rate | Cost/100 km (Ioniq 6) |
|---|---|---|
| Public AC (7–22 kW) | €0.45/kWh | €7.88 |
| DC fast (50–150 kW) | €0.59/kWh | €10.33 |
| Ionity DC (without subscription) | €0.79/kWh | €13.83 |
| Tesla Supercharger (subscription) | ~€0.32/kWh | €5.60 |
At €0.79/kWh on Ionity, an Ioniq 6 costs more per 100 km than a diesel Golf. This is not an argument against EVs — it's an argument for not fooling yourself if your charging situation is unfavourable.
How much does installing a home charging point cost in Belgium?
The saving only materialises if you can charge at home. Here is what installation costs:
- Green'up reinforced socket (3.7 kW): €400 to €800 installed
- 7.4 kW wallbox — what 90% of private users need: €800 to €1,500 installed
- 11 kW wallbox (three-phase, detached house): €1,200 to €2,500 installed
The Belgian tax deduction for home charger installation is 30% of costs, capped at €1,750, meaning a maximum reduction of €525 on your tax bill.
For a wallbox at €1,200 installed: net cost after deduction = €675. With the fuel saving of €878/year calculated above, the wallbox pays for itself in under a year.
Is it worthwhile to install solar panels to charge your EV in Belgium?
If you have panels or plan to install them, the effective electricity cost can drop to €0.02–0.05/kWh in direct self-consumption — that's the amortised installation cost over its lifetime, not the grid price.
Cost per 100 km with an Ioniq 6 charged on solar: between €0.35 and €0.88. That's 10 to 30 times less than petrol.
Le verdict de Christophe F.
Home charging in off-peak hours is two to four times cheaper than petrol per kilometre. Charging on a public fast charger wipes out that advantage. The economic equation for EVs is favourable if — and only if — you can charge mainly at home.
