Electricity suppliers

The best electricity supplier in Belgium in 2026 is Mega for most households, thanks to the lowest variable tariffs on the market and a transparent, 100% Belgian offer. But "the best" depends on your profile: a household that wants genuinely green power will prefer Bolt or the Ecopower cooperative; one that values the peace of mind of a large group will look at Eneco or Engie. This ranking compares the suppliers active on Belgium's liberalised market (Wallonia, Brussels, Flanders) on price per kWh, standing charge, share of renewable energy, contract flexibility and customer service quality. Prices quoted are indicative (June 2026) for an average household using about 3,500 kWh per year, excluding one-off promotions: always check your exact case via the official CREG, VREG or CWaPE comparison tool before signing.
