New English website

From now on, you'll find our information here also in English.


Our SUDenergie website is now also available in English, offering an alternative for people who are not that familiar with French and German, the two existing language versions.

With an increasing English-speaking population and a growing community of expats in Luxembourg, English is getting more and more relevant in our customer communication. It was thus only logical to make our online information also available in English.

“We constantly aim to improve our customer service, and we hope that providing our content also in English will allow more people to find the information they need”, says Alain Fürpass, CEO of SUDenergie.
