If you are moving into an existing building that is already connected to the electricity and natural gas networks, all you have to do is contact the supplier of your choice and sign a supply contract.
If however the building is not yet connected, the connection must be requested from the relevant network operator. The distribution network operator has a legal monopoly on the distribution network in a given area. This should not be confused with the supplier, which you can freely choose. The list of electricity and natural gas network operators and their contact details is available on the ILR website.
In order to be supplied with electricity and/or natural gas, you should, if possible, conclude a contract with the supplier of your choice before the connection is made or before you move in. The list of electricity and natural gas suppliers can be found on the website www.STROUMaGAS.lu. The price comparison tool www.calculix.lu gives an overview of the products being marketed by the suppliers.
