Yes — switching energy supplier in Belgium is completely free, with no penalty fees. The standard notice period is one month. Your new supplier handles the switch and takes care of all the paperwork.
The whole process usually takes three to four weeks. There is no interruption to your supply — the same physical electricity and gas flow into your home; only the billing party changes.
A fixed tariff locks in the price per kWh for the entire contract length (often one to three years), protecting you against price spikes. A variable tariff follows the wholesale market — usually a quarterly index — so the price can go up or down at every billing cycle.
An EAN code is the 18-digit unique identifier of your electricity or gas meter. You need it when signing a new energy contract — it tells your supplier exactly which meter to bill. You can find it on a previous energy invoice or on the meter itself.
