Eneco reviews: ratings, customer service and real prices

Eneco gets average online reviews, 3.4 out of 5 on Trustpilot, but a score of 4 stars out of 5 from the Flemish regulator, which counts actual complaints. Its two real weak spots lie elsewhere: a customer service that is hard to reach on the right number, and a €203 a year gap between its own offers.

Trustpilot 3.4, Google 1.6, regulator 4 out of 5: four scores for one supplier

They do not measure the same thing, and that is the whole point.

The Trustpilot score comes from Selectra's reviews page, the Google and Selectra scores from CallMePower's Eneco page, the Flemish indicator from its 10 September 2026 update and the Greenpeace score from the ranking presented on 3 December 2025. Selectra and CallMePower are Belgian comparison sites.

Two comparison sites, one remark. Selectra and CallMePower, which belong to the same group, both display Eneco as a commercial partner, and CallMePower states that it is paid when a visitor signs up through its buttons. Their figures remain useful, and we quote them. We, for our part, earn no commission from Eneco or any other supplier, and the article below offers you no sign-up button.

A Google score built on 128 reviews says almost nothing about a supplier active in two regions.

Why does the Flemish regulator rate Eneco better than Google?

Because it counts complaints, not moods. The Vlaamse Nutsregulator (VNR, formerly VREG), the Flemish energy regulator, relates to customer numbers the complaints that reach it or the ombudsman, meaning those the supplier failed to settle itself, and turns them into a score from one to five stars.

On this measure, Eneco has clearly improved. Its index fell from 9.53 in 2023 to 5.25 in 2024, the index being the number of complaints per 1,000 customers multiplied by five: roughly 1.9 and then 1.05 second-line complaints per 1,000 customers. The score followed, from 2 to 4 stars. For comparison, Luminus stood at 2.66 in 2024, Bolt at 3.03, Engie at 4.43, OCTA+ at 6.60, Mega at 6.81 and TotalEnergies at 9.30. The same report notes, however, that Eneco's share of complaints remained higher than its market share in 2024.

The 10 September 2026 update, calculated over the four quarters ending in June, keeps Eneco at 4 stars despite a rise in its complaints, according to Selectra's reading of it. Engie, Luminus, Bolt and Ecopower get 5 stars, Mega 2.

One limit remains. This indicator only covers Flanders. At federal level, the Energy Ombudsman received 10,091 complaints in 2025, down 21.8 %, without publishing a breakdown by supplier in its press release. Meters account for 24.7 % of complaints, billing for 18.8 %, and suppliers' customer service for barely 4.2 %. The last breakdown by supplier made public, from the 2023 report relayed by CallMePower, attributed 2,761 complaints to Eneco, against 7,870 to Engie and 4,205 to Luminus.

Which number should you call to reach Eneco's customer service?

It is the most searched question about Eneco, far ahead of reviews, and the answer online is confusing. We recorded the numbers published by Eneco itself and by three sites competing for that search.

Three sites, three "customer service numbers". The last one on the list deserves a closer look: the page that publishes it states itself that it is run by CallMePower, a partner of Eneco. You can sign a contract there; it is not the right channel to dispute a bill. The rule fits in one sentence: use the number printed on your latest bill or shown in your My Eneco account, it takes precedence over anything a third-party site publishes, this one included.

The hours announced by comparison sites are the same everywhere, Monday to Friday from 8 am to 6 pm. Eneco gives no direct email address and points to its contact form, which routes requests by department. The My Eneco portal covers most routine tasks: downloading a bill, changing an instalment, updating your details, reporting a move. HelloSafe mentioned an online virtual assistant in 2024, without further detail.

Two more traps. Eneco has no breakdown number: a power cut or a smell of gas is a matter for the distribution system operator (DSO, called GRD in French), ORES or RESA in Wallonia, Fluvius in Flanders. And the postal address also varies with the source, Battelsesteenweg 455i in Mechelen in Eneco's documents, Blarenberglaan 2C on comparison sites: for a registered letter, copy the one on your contract.

Is Eneco expensive?

Less than you might think with the right plan. Far more with the wrong one.

On 23 October 2026, Selectra lists four Eneco electricity offers in Wallonia, all estimated for 3,500 kWh a year on a single-rate meter, network costs and taxes included.

The benchmark comes from CallMePower's ranking for Namur, checked the same day: it was the cheapest offer in Wallonia. The two tools do not calculate in exactly the same way, hence a €2 gap on Flex One between them (€1,440 at CallMePower, with an energy price of 16.71 c€/kWh and a standing charge of €50 a year as of 1 October 2026).

The calculation that matters happens inside the range. Between Flex One and Vast, the gap reaches €203 a year. Between Flex One and Flex, two variable green electricity plans that differ only by term, it still reaches €112 a year, and the open-ended plan is typically the one left on the bill of customers who have been there for years, since it has no end date that forces a review. By contrast, the gap between Flex One and the cheapest offer on the Walloon market is only €74. An Eneco customer still on Flex therefore loses more by keeping an old plan than by staying with Eneco.

Before leaving, ask Eneco to move you to the current plan, then compare the result in our bill simulator.

Wallonia and Flanders: two Eneco ranges

In Wallonia, the range is complete, on the grids of ORES, RESA and the other DSOs overseen by CWaPE, the Walloon energy regulator. The bill there carries a much heavier renewable energy contribution: €112.70 for 3,500 kWh in CallMePower's Flex One estimate, or 3.22 c€/kWh, against €53.20 (1.52 c€/kWh) in its Flemish estimate. This item depends mainly on regional green certificate quotas, not on a commercial choice by Eneco.

In Flanders, CallMePower also prices the dynamic offer Zon en Wind Dynamique, absent from Selectra's Walloon list, whose price follows the Belpex market every hour, with a standing charge of only €15 a year. CallMePower estimates it at €1,328 a year on the Fluvius West grid, provided you have a smart meter and can shift your consumption. Fluvius's capacity tariff is added anyway, whatever the supplier, and Flanders is the only region with an official service score.

Does Eneco still supply Brussels households?

No. On 22 September 2023, Eneco announced the end of its residential activities in the capital, where it then had about 2,700 electricity contracts according to figures from Brugel, the Brussels energy regulator, quoted by Test-Achats, letting existing contracts run to their end. In October 2026, Selectra still lists it as unavailable to Brussels households. Simulate your bill on Brusim instead.

What complaints come up against Eneco?

Five, of uneven weight, found in visible reviews and on comparison sites:

• Open-ended plans. Flex and Vast cost €112 to €203 more a year than Flex One in Wallonia, and their terms can be revised every year.
• How price rises are communicated. Some customers describe poorly explained increases and final bills that are slow to arrive, a recurring signal on Selectra rather than a statistic.
• Waiting on the phone at peak times, made worse by the confusion over numbers described above.
• Slipping green credentials. Greenpeace moved it from 16 to 13 out of 20 between its 2023 and 2025 rankings.
• Extra charges for energy sharing between neighbours, an option made possible by the smart meter.

On Eneco's credit side, three points also come up: green electricity at no extra price, a consumption tracking app, and the Comfort Bonus, a free assistance programme (home breakdown help, bike, electric car) open after one month of contract, extended after one year to household appliances and to partial cover of instalments, capped at €75 a month, in case of involuntary loss of income. Contracts signed through a group purchase and the Go, Link, Basic and Start plans are excluded, according to CallMePower.

Eneco by situation

To place Eneco against the rest of the market, our ranking of the best electricity suppliers applies the same criteria to every player, and the head-to-head Eneco or Luminus covers the duel with its closest competitor. Our analysis of Luminus reviews follows the same method, if you are hesitating between the two.

Leaving remains free, with one month's notice and no termination fee, as with every Belgian supplier: our guide to cancelling an electricity contract explains the steps, and our article on fixed or variable contracts helps you choose between Flex One and Fix One. If a dispute with Eneco drags on, the federal Energy Ombudsman remains free of charge and also handles billing complaints.
