Check the feasibility

Determine and agree on the terms and conditions

During an on-site appointment, we will survey the premises and provide you with instructions on any work that may need to be performed beforehand (e.g. trench for the connection line or opening in a wall).


Note: You are responsible for the trench between the natural gas distribution network and the connection point for your building. The necessary permits for carrying out work on public property must be obtained before the work begins. SUDenergie will connect you to the natural gas distribution network at the time agreed with your contractor.


Estimate and order placement

Quotation and signing of the contract

You will receive a quote estimating the costs of connecting to the natural gas network. By signing the “Conditions Particulières du Contrat de raccordement” (Special Connection Contract Conditions), you give us the order to carry out the connection work.


Before starting the installation work in your building, we ask that you fill out the “Application for commissioning of an installation” form and the Alugaz “Notification of work on a gas installation” form together with your installer.


The gas installation may only be carried out by an approved installer. You can find a list of approved installers in Luxembourg here.


Your natural gas installation

by your installer and SUDenergie

After certifying and checking the conformity of the natural gas installation, SUDenergie installs the meter. We will arrange an appointment with you to do so.

Once your meter has been installed, you will receive a bill for the installation costs and the network usage contract, which you must return to SUDenergie as soon as possible.

The installation work is complete.

For whom is the network connection intended?

For homeowners who have decided to switch to a more economical form of heating (which makes it easy to choose the inclusion of renewable energy).

How does SUDenergie help with the network connection?

We offer expert advice on site and draw up a (free) estimate for the connection work.
