My energy supplier is raising prices in Belgium. What can I do?

The short answer

A supplier cannot raise your price overnight. It has to warn you in advance, and that notice often gives you the right to leave.

📜 The rules in Belgium

Price rises

In a fixed-term contract the supplier may not change conditions to your disadvantage. In an open-ended contract it must announce unfavourable changes, such as a new price, at least two months ahead. You can always leave with one month's notice, free.

Switching supplier

Sign with the new supplier; it arranges everything, including ending your old contract. The legal notice is one month (in practice about 3–4 weeks). No termination fee is allowed, but some suppliers still charge the fixed annual fee for a full year.

❓ Questions

Can a fixed price be raised?

Normally not during the fixed period, unless your contract says so. Taxes and levies can still change.

Do I pay an exit fee if I leave after a price rise?

In many countries you can leave without a fee when the price goes up. The rules for Belgium are on this page.

What if I missed the letter?

Ask the supplier for a copy and the date it was sent. If they cannot show proper notice, complain.
