Watz : A Belgian Energy Supplier


Watz is a young Belgian energy supplier which supplies natural gas and green electricity in Flanders and Wallonia. At Watz, they prioritize transparency and clarity over discounts and promotions, so customers have only one variable price plan to choose from, covering gas, electricity, or both.

Watz in a Few Words

Watz is a small Belgian energy supplier with more than 20,000 customers in Flanders and Wallonia today.

Watz does not produce natural gas or electricity, the supplier buys the energy sold on international markets. To assure its customers that the electricity is produced in Belgium and comes from renewable sources, Watz also purchases certificates of origin. In this regard, Greenpeace believes that "the purchase of guarantees of origin has only limited ecological added value" in the sense that Watz does not invest directly in the production of renewable energy. For this reason, the supplier receives a score of 7/20 in the latest Greenpeace report on the environmental footprint of electricity suppliers in Belgium.

Simplicity combined with competitive prices is the hallmark of the energy supplier Watz. Indeed, it only offers a small number of formulas for the supply of energy and offers the same services and options to all its customers.
