Energy Supplier Bankruptcy in Belgium: What Happens and What to Do

An energy supplier shutting down is not a theoretical scenario in Belgium: in December 2021, the bankruptcy of Vlaamse Energieleverancier pushed some 70,000 customers into emergency supply overnight. The good news is that nobody ends up without electricity or gas. The bad news is that the meter keeps running — literally and figuratively — at a noticeably higher rate, and that advance payments already made disappear into a bankruptcy procedure. Here is exactly what happens, and in what order to act.

What actually happens if my energy supplier goes bankrupt?

You are not cut off. Supply automatically switches to your municipality's distribution network operator, which acts as a last-resort supplier until you sign a new contract.

This safety net is written into Belgian regulation, precisely to prevent a commercial failure from leaving a household without heating or lighting. In practice, an enterprise court declares the bankruptcy and appoints a receiver; in parallel, the network operator takes over the affected supply points. You need to do nothing for energy to keep arriving: it simply keeps arriving. The break is administrative and financial, not physical.

Who delivers my electricity and gas in the meantime?

Your distribution network operator (DSO) — the company that manages the cables and pipes in your street, not the one that used to send you invoices.

In Flanders, a single operator covers the whole territory: Fluvius. In Brussels, it is Sibelga. In Wallonia, several operators coexist depending on the municipality: ORES covers the largest share of the territory, RESA the Liège area, and two smaller intermunicipal operators, AIEG and AIESH, serve a few zones. You do not choose your network operator: it depends solely on your address. In Wallonia, the mechanism can also run through designated substitute suppliers, to which customers without a new contract are attached on a set date — which is what happened when supplier Aeco ceased trading.

How long can I stay with the last-resort supplier?

In principle around sixty days. Beyond that, you must have signed a contract with a commercial supplier — and it is better not to wait for the deadline.

That period is not a right to stay: it is a reprieve. Every week spent in emergency supply is billed at the emergency rate, higher than any market offer. The arithmetic is simple: if you consume 3,500 kWh of electricity per year and the emergency rate exceeds the market by several cents per kWh, two months of delay easily represents several tens of euros lost for nothing. Signing a new contract takes about twenty minutes, and the new supplier handles the switch.

Why is the last-resort rate so high?

Because the network operator has to buy at short notice, at the price of the day on the wholesale market, volumes it had not anticipated.

A commercial supplier plans its purchases months in advance and smooths out the price it charges you. A network operator placed in a last-resort position has planned nothing at all: it suddenly finds itself with tens of thousands of supply points to serve. When Vlaamse Energieleverancier went bankrupt in December 2021, the rates Fluvius applied to the customers it took over were appreciably higher than the commercial market, for precisely that reason — not out of any desire for margin. Context mattered too: the 2021-2022 wholesale price crisis was exactly what had put several suppliers under financial strain.

Note that these emergency rates are not fixed: they follow wholesale market movements and are reassessed periodically. The CREG, the federal regulator, publishes the rules applying to rates charged when a contract ends at the supplier's initiative. The exact amounts depend on your region and the period: always check the rate in force at the moment you are concerned.

Will I get back the advance payments I made?

Nothing guarantees it, and statistically the odds are slim. An excess advance payment makes you a creditor of the bankrupt company, but an ordinary creditor, with no privilege.

This is the most painful part of the file. Under normal circumstances, overpaid advances are refunded at the annual settlement. In a bankruptcy, that settlement does not take place as planned: your claim joins the estate and the receiver applies the legal repayment order. Privileged creditors come first — the company's employees, the tax authorities, social security — and consumers, known as chirographic creditors, share what is left. Often little or nothing remains.

How do I file a claim with the receiver?

Two routes are open to you: filing online through the Central Solvency Register, or contacting the receiver appointed by the enterprise court directly.

The Central Solvency Register (RegSol) is the official register of Belgian bankruptcies: it is where procedures are published and where creditors file their claims. The procedure to follow:

1. Gather the useful documents first: your advance invoices, proofs of payment, your last annual statement and your meter readings on the day of the switch.
2. Open the bankruptcy file on RegSol to find the receiver's name and the filing deadline, which is binding.
3. File your claim online on RegSol, or contact the receiver directly, who will send you the necessary documents.
4. Keep your meter readings: they also help avoid disputes over how consumption is split between the former supplier and the last-resort supplier.

If a disagreement follows, the Federal Energy Ombudsman Service handles disputes between consumers and suppliers or network operators free of charge. In Wallonia, the CWaPE regional energy mediation service covers regional aspects, including compensation.

What signs show that a supplier is fragile?

No indicator is foolproof, but a few signals deserve attention:

• Sudden, poorly explained increases in advance payments.
• Repeated delays in sending annual settlements.
• An unreachable customer service.
• Public communication about financial difficulties.

A rise in advance payments is not abnormal in itself — it follows consumption and market prices. What should raise a flag is a large rise with no clear justification, especially combined with settlement invoices that stop arriving. In that case, one simple precaution: bring your advance payment back in line with your actual consumption rather than letting a buffer build up at the supplier. Our guide on lowering your energy advance payments explains how, and that caution is worth taking outside any bankruptcy context too.

How do I choose a new supplier without rushing?

By comparing total annual cost, not the headline price per kWh — even when urgency pushes you to sign quickly.

The urgency is real, but it does not justify taking the first offer that comes along. Three criteria are enough to decide in ten minutes:

• The total cost in euros per year for your actual consumption, fixed fee included.
• The contract type: fixed, variable or dynamic.
• Whether termination fees apply.

The CREG Scan comparison tool from the federal regulator lets you measure your situation against current market prices, and our energy supplier ranking sets offers side by side on a typical household profile. For the full method, our article on how to choose an energy supplier in Belgium details every criterion, and if you also want to check how genuine an offer's environmental claims are, our analysis of green energy suppliers separates real commitments from mere packaging.

One reassuring point to close on: switching to a new supplier requires no technical intervention. No cut-off, no site visit, no new meter. The new supplier notifies the network operator and the takeover is based on your meter readings. The procedure is the same as for a voluntary switch, described in our guide to switching energy supplier in Belgium.

Key takeaways

A supplier bankruptcy never leaves you without energy: the network operator takes over automatically. But that stopgap is expensive and not meant to last — count on roughly sixty days to sign elsewhere, and act within the week instead. In order:

1. Cancel the direct debit as soon as the bankruptcy is announced.
2. Record your meter readings.
3. File your claim on RegSol, even if the chances of recovering your advance payments are slim.
4. Compare on total annual cost before signing a new contract.

Rates move constantly: always check the amounts in force at the time of your decision on the energy supplier ranking.
