Why "the cheapest" doesn't exist as a fixed name
Two households with exactly the same yearly usage can pay a different amount at the same supplier, depending on exactly when they use electricity, whether they have solar panels, and how their usage splits between day and night. A ranking built on one average profile is at best an indication — never an answer for your specific situation.
What a fair comparison actually needs
Your own, measured quarter-hourly usage (from your smart meter), recalculated against the current tariffs of multiple suppliers — fixed, variable, AND dynamic contracts — produces a figure that's specific to you, fixed fees included and, with solar panels, the feed-in compensation.
Where the tariffs come from
We use the public V-test data from VREG, the Flemish energy regulator, updated monthly with every supplier's products and their exact price components — no estimated prices, no sponsorship from a supplier that could influence the outcome.
Making the choice yourself
We don't name a "best" supplier ourselves — you see every recalculated alternative next to your current contract, with the difference in euros per year. That way you decide, based on your own numbers, whether switching is worth it.
