TotalEnergies or Eneco: how to decide
TotalEnergies and Eneco are both active on the Belgian residential market, in electricity as in gas. They are not separated by an overall price level but by how their ranges are built — which is why a headline comparison between them tells you almost nothing.

Two ranges built differently
The two suppliers do not structure their electricity ranges the same way, mixing guaranteed-price contracts and indexed contracts in different proportions.
On gas, both offer fixed-price contracts. The difference therefore lies not in market coverage, which both provide, but in which formula is available at what terms.
Hence a reading rule: compare energy by energy and formula by formula. Setting one supplier's fixed contract against the other's indexed contract compares two different products and produces a meaningless answer.
Flat-rate advantages distort the unit price
Both ranges contain advantages expressed in euros rather than in cents per kilowatt-hour: an annual reduction, a welcome credit, a discount on an associated product.
A flat-rate advantage weighs proportionally more the less you consume. On a small household, an annual reduction can be worth more than a visible difference in unit price — and on a large one, almost nothing.
A second and simpler filter: only count an advantage you will actually use. A discount on solar panels is worth nothing to a tenant, and it belongs out of your calculation.
What you still have to check yourself
Both offer contracts backed by guarantees of origin. That label is regulated but very widespread on the Belgian market, so on its own it does not separate the two.
A unit price only becomes an amount once multiplied by your consumption and increased by the contract's standing charge. Do that calculation for the specific formulas you are considering.
Finally, re-date your comparison at every renewal. The right to terminate on thirty days' notice, free of charge, applies to every residential customer in Belgium and makes that habit worthwhile.
Our verdict
A few hundredths of a cent per kilowatt-hour say nothing; the annual standing charges speak. Compare energy by energy and formula by formula, then add the standing charge to the unit price times your consumption. Anything else compares two products that are not the same product.
Frequently asked questions
Is TotalEnergies cheaper than Eneco?
Not structurally. Their ranges are built differently and their relative order changes with the tariff card and the consumption profile, so the answer depends on which formulas you compare and on the date rather than on the brand.
Can an indexed offer be compared with a fixed-price one?
Only with care: they answer different questions. A fixed price protects against a rise and forgoes a fall; an indexed one follows the market both ways. Compare formula against formula, not one supplier's fixed against the other's indexed.
How do I factor an annual reduction into the comparison?
Convert it into cents per kilowatt-hour by dividing it by your annual consumption. That is the only way to set a flat-rate advantage against a unit price — and it weighs proportionally more the less you consume.
Does a guarantee of origin separate the two?
Not on its own. The label is regulated but very widespread on the Belgian market, so both suppliers offer contracts backed by it. It is a floor rather than a differentiator between these two.
