energy suppliers

For an average Belgian household, Mega remains in 2026 the cheapest energy supplier on a variable gas + electricity contract, ahead of Bolt and Eneco; incumbents Engie and Luminus are still 10 to 15 % more expensive, though their "online" and dynamic tariffs close part of the gap. This ranking compares seven suppliers active across the whole country on what actually matters: the total annual cost for a reference household (3,500 kWh of electricity + 17,000 kWh of gas), the readability of the indexation clause, the quality of customer service and the credibility of the green offer. It contains no affiliate links: no position is for sale, and every price is cross-checked against the CREG Scan and the regional regulators' comparison tools (CWaPE, VREG, Brugel). One warning up front: in energy, no ranking stays true forever. Variable tariffs are re-indexed monthly or quarterly, and a supplier ranked first in January can drop to fourth by June. The right method is therefore not to copy a Top 7, but to understand why these suppliers rank this way — and then check your own case with your real consumption, your region and your meter type.
