Switching energy supplier in Belgium: steps, notice and pitfalls (2026)

Can you really switch at any time?

Yes. For households, switching is free, including during a fixed-term contract, and with no termination fee. It is one of the benefits of a liberalised market: competition works in your favour.

The process, step by step

1. Compare offers by region and consumption. Our electricity comparator and gas comparator rank plans by real annual cost.
2. Contact your chosen supplier (online, by phone or in writing). Give your annual consumption, your EAN code and the desired start date.
3. Sign the new contract. The supplier notifies the grid operator and handles the cancellation with the old one.
4. Send your meter reading when the grid operator asks for it.
5. Receive the closing invoice from your old supplier, about a month after the new contract starts.

Notice and timelines by region

In all cases, the new supplier must handle your request within 10 working days, and the effective transfer usually takes three to six weeks.

Myths to forget

• “I’ll be cut off during the switch” — false, supply is guaranteed continuously.
• “Cancelling is expensive” — false, there is no termination fee.
• “It’s complicated” — false, the new supplier handles everything; you mainly provide your EAN code and a reading.

And after?

Variable prices change every month: comparing once a year is enough to avoid overpaying. Not sure which plan fits your profile? Take the “which supplier” test — it recommends a plan in a few questions.
