Frequently asked questions

Which electricity supplier is cheapest in Belgium in 2026?

As recorded on 1 July 2026, Ecopower has the lowest annual cost (~€1,252/year for 3,500 kWh) but only serves Flanders and requires co-op shares. Outside cooperatives, Ecofix is cheapest in Wallonia (~€1,261/year). Variable rates change monthly — check the current offer before subscribing.

Is the ranking the same in Wallonia, Flanders and Brussels?

No. The Belgian market is regionalised: Ecopower only supplies Flanders, Cociter only Wallonia, and the Brussels residential market is narrower (mainly ENGIE, Luminus, TotalEnergies, Bolt). Distribution tariffs also differ by grid operator.

Should I look at the kWh price or the annual cost?

The total annual cost. A low kWh rate paired with an €80-90/year fixed fee can cost more than a slightly higher rate with no fee — exactly the OCTA+ versus Ecofix case in this ranking.

Does switching supplier cut off my power?

Never. Switching is free, with no outage and roughly one month's notice. Your new supplier handles the cancellation.
