TotalEnergies or Mega: which supplier should you choose?

TotalEnergies or Mega: this is a face-off between two philosophies. On one side, TotalEnergies, the Belgian subsidiary of the French giant, which bets on a complete ecosystem; on the other, Mega, the 100% Belgian challenger that tops the comparison sites on price. Here is what really sets them apart in 2026, and how to choose based on your profile. For the full market picture, see our ranking of the best electricity suppliers.

TotalEnergies or Mega: which is cheaper?

Mega is almost always cheaper than TotalEnergies on electricity alone. On a variable contract, Mega shows a price per kWh among the lowest on the market, often around €0.15 to €0.16, while TotalEnergies' myEssential Variable offer runs closer to €0.16 to €0.165 (roughly 13.3 to 16.4 c€/kWh depending on the period and region). The gap looks slim per kWh, but it widens over the year, and above all Mega has no brand costs to pass on. That is what regularly earns the Belgian supplier a top spot in the Test-Achats Energy barometer for value for money.

What is the concrete price difference over a year?

For an average household consuming 3,500 kWh a year, the gap between Mega and TotalEnergies is most often between €100 and €300 on electricity alone. In practice, TotalEnergies' cheapest variable offer comes to around €1,300 to €1,350 a year for this profile, against often €1,050 to €1,250 with Mega. Beware, though: TotalEnergies, like Engie or Luminus, regularly offers welcome promotions that shave the gap in the first year, before the rate climbs back to its normal level. The right reflex is still to compare every year on the official comparison tool of the CREG, VREG or CWaPE depending on your region.

What does TotalEnergies offer that Mega doesn't?

TotalEnergies bets on a multi-energy ecosystem that Mega lacks. Where Mega essentially sells electricity and gas, TotalEnergies also covers fuel at the station, a network of charging points for electric cars, home services and a single app to manage everything. For a household that drives electric or wants to bundle all its energy with a single player with a loyalty programme, this integration has real value. Mega, by contrast, embraces the opposite: a simple offer, few options, but a low price and 100% online management with no frills.

TotalEnergies or Mega for green electricity?

Neither is the best choice for truly local green power. TotalEnergies now declares that all its electricity offers are of renewable origin, and Mega also offers green plans — but in both cases this relies largely on guarantees of origin, a mechanism that greens the electricity on paper without guaranteeing Belgian production. If environmental impact is your priority, suppliers like Bolt or the citizen cooperative Ecopower rely on clearly more credible Belgian renewable production. Between TotalEnergies and Mega strictly, the green argument should not tip the balance: look first at price and services.

Which supplier should you choose for your profile?

For most households that simply want to pay less, Mega wins. It is the default choice for a home attentive to its bill, comfortable with online management and a variable rate. TotalEnergies suits a different profile better: a household that drives electric and wants integrated charging points, that already has a group fuel card, or that prefers to bundle electricity, gas and mobility with a single large multi-energy player. A cautious household that fears price increases can, with either one, opt for a one-year fixed contract — a little pricier, but locked in.

How do I switch from TotalEnergies to Mega (or the other way)?

The switch is free, with no cut-off, and handled by the new supplier. In practice, you sign up with Mega (or TotalEnergies) with a recent bill on hand — for your EAN code and annual consumption — and the new supplier notifies the old one and organises the switch. The physical grid, managed by your distribution system operator (Ores, Fluvius, Resa or Sibelga depending on your municipality), does not change: electricity keeps flowing without interruption. Household contracts can be cancelled at any time with one month's notice, free of charge.

In short, if your goal is to pay the fair price for your electricity, Mega beats TotalEnergies in most cases. TotalEnergies keeps its place for those who want a complete multi-energy ecosystem and the reassurance of a large group. Before signing, always check your specific case on the official comparison tool of the CREG, VREG or CWaPE, and compare the whole market in our ranking of electricity suppliers.
