A kWh of electricity in Belgium costs between 30 and 41 cents all taxes included, depending on your region. That figure only holds for the "extra" kWh, though. The average price you really pay depends on your consumption, your fixed charges and your contract, and it can go above 50 cents.
How much does 1 kWh of electricity cost in Belgium?
About 41 c€ in Wallonia, 39 c€ in Brussels and 30 c€ in Flanders. These are the averages of the variable part of the bill, the part that rises with every kWh used, published by Test-Achats, the Belgian consumer association, on 18 September 2026. They add up energy, transmission, distribution, surcharges and VAT. The spread between offers remains wide: from 35 to 49 c€ in Wallonia, from 25 to 37 c€ in Flanders.
Flanders looks unbeatable, but not for everyone.
Why does your average price change with your consumption?
Because part of the bill does not depend on kWh. The supplier's standing charge, fixed grid fees and, in Flanders, the capacity tariff based on your peak power: Test-Achats puts these charges at about 85 € a year in Wallonia, 165 € in Brussels and 335 € in Flanders for an average power level. The more you use, the more that amount is diluted. The less you use, the more it weighs on each kWh, and that is exactly what skews most of the comparisons I come across, where a "price per kWh" is quoted without saying which household it was calculated for, even though a studio flat and a house heated by a heat pump do not pay anything like the same average price at the same address.
So we redid the maths for three profiles, adding fixed charges to the variable part.
| Annual consumption | Wallonia | Brussels | Flanders |
|---|---|---|---|
| 1,500 kWh (studio, small flat) | 46.7 c€ / 700 € a year | 50.0 c€ / 750 € a year | 52.3 c€ / 785 € a year |
| 3,500 kWh (typical household) | 43.4 c€ / 1,520 € a year | 43.7 c€ / 1,530 € a year | 39.6 c€ / 1,385 € a year |
| 8,000 kWh (heat pump or electric car) | 42.1 c€ / 3,365 € a year | 41.1 c€ / 3,285 € a year | 34.2 c€ / 2,735 € a year |
Average price per kWh and annual bill, all taxes included. Our own calculation based on the Test-Achats September 2026 averages (variable part and average fixed charges). Orders of magnitude: your offer may differ by several cents.
For a typical household, the result matches market figures. Selectra estimated the median contract at 44.74 c€ per kWh for 3,500 kWh on 2 November 2026, and CallMePower placed Walloon offers between 1,368 and 1,782 € a year on the same day. To check your own case, the official comparison tool of the CWaPE remains the reference. If you do not know your consumption, our page on average electricity consumption helps you place yourself.

Flanders becomes the most expensive below 2,300 kWh a year
It follows directly from the table. With 11 cents less per kWh but 250 € more in fixed charges than Wallonia, Flanders only catches up from about 2,273 kWh a year, by our calculation. Against Brussels, the tipping point is around 1,900 kWh. Below it, a small Flemish consumer pays more per kWh than a Walloon or a Brussels resident. Above it, the Flemish advantage grows fast, and an all-electric household using 8,000 kWh saves about 630 € a year compared with Wallonia.
The official CREG tariff confirms the ranking for heavy users. This amount, set by the CREG, the federal electricity and gas regulator, and used to reimburse home charging of company cars, is calculated for an 8,000 kWh household with an electric car, all charges and VAT included. For the fourth quarter of 2026, according to circular 2026/C/86 of 11 September, it stands at 32.25 c€ in Flanders, 36.88 c€ in Brussels and 37.79 c€ in Wallonia. Our figures are 2 to 4 cents higher: the CREG averages May, June and July, before the rise that CallMePower puts at 17 % between August and October.
What is the price per kWh at Engie, Luminus or Mega?
It all depends on the offer, and the advertised figure only covers energy. Here is the energy component of a few contracts recorded in early November 2026, single-rate meter, before promotions.
| Supplier and offer | Type | Energy per kWh | Standing charge | Recorded |
|---|---|---|---|---|
| EnergyVision, 1-year fixed (Wallonia) | Fixed | 13.57 c€ | not specified | CallMePower, 02/11/2026 |
| Engie Basic Online | Variable | 19.57 c€ | 20 € a year | CallMePower, 02/11/2026 |
| Mega Online Flex (Wallonia) | Variable | 20.46 c€ | not specified | Mega, October 2026 |
| Engie Easy Vast | Fixed | 23.10 c€ | 69 € a year | CallMePower, 02/11/2026 |
| Luminus ComfyFlex+ (Wallonia) | Variable | 23.85 c€ | not specified | CallMePower, 02/11/2026 |
| Luminus Comfy+ (Wallonia) | Fixed | 26.24 c€ | not specified | CallMePower, 02/11/2026 |
Engie tariffs are given including VAT by CallMePower. The other records do not always specify VAT or the standing charge: check the supplier's tariff sheet before signing.
Between the first and last rows, the gap reaches 12.67 c€ per kWh. For 3,500 kWh, that is about 440 € a year, on a bill of about 1,500 €. No other item offers such a margin. Grid charges, excise and VAT are the same for every supplier at a given address, as we explain in our article on VAT and excise.
All-in price or energy price: which one should you compare?
The all-in price to know your budget, the energy price to choose a supplier. The two get mixed up constantly on websites and in adverts. On the bills I take apart, five confusions keep coming back:
- Energy alone presented as "the price per kWh": 20 c€ in an advert becomes 40 c€ on the bill, once grid charges and taxes are added.
- The forgotten standing charge: 20 € at Engie Basic Online, 69 € at Engie Easy Vast, which changes the ranking for a small consumer.
- Excl. VAT compared with incl. VAT: grid operator and CREG sheets often work excluding VAT, supplier sheets including it.
- The first-year promotion: several Engie offers show a discount that disappears at renewal, and CallMePower leaves it out of its tables.
- The dual rate ignored: with a dual-rate meter, the night price per kWh can be six cents lower than the day price on energy alone.
The average split gives the order of magnitude. Selectra estimates it, for a 3,500 kWh Walloon contract, at 42 % for energy, 32 % for the grid, 14 % for federal excise, 6 % for public service obligations and 6 % for VAT. The CWaPE, the Walloon energy regulator, details the regional surcharges built into distribution tariffs.

How much do 1,000 extra kWh cost?
About 300 € in Flanders, 390 € in Brussels and 410 € in Wallonia, at the September 2026 marginal price. It is the right benchmark for costing a new appliance: an electric car adding 2,500 kWh a year therefore costs a little over 1,000 € in Wallonia, excluding charging elsewhere.
How can you pay less per kWh?
By working on the only line that moves: energy. Switching from a 26 c€ offer to a 14 c€ one brings in more than any announced tax cut. Excise duty, which replaced the federal contribution according to the CREG, will only fall from 48.76 € to 40.28 € per MWh including VAT by 2029, according to the trajectory voted in May 2026 and published by Infor GazElec, a Brussels consumer information service, which is less than one cent per kWh.
Three habits are enough. Reread your contract to know whether you are on a fixed or variable price, and when it renews. Compare the energy component and the standing charge, not the "all-in" price of an advert. And if you use little electricity in Flanders, watch your peak power rather than the price per kWh. Our ranking of the best electricity suppliers compares offers on these criteria, and the bill simulator puts a figure on your case by region and consumption.
