Partial payment on invoices

Following the new electricity law of June, 6th 2023, Sudstroum informs its customers of the possibility of scheduling partial payments of unpaid invoice(s). The amount and/or number of monthly payments (scaling of unpaid amounts) must be fixed by mutual agreement between the customer and Sudstroum. This measure aims to avoid any cut in electricity supply.

Please send us your requests to Email: backoffice@sudstroum.lu Telephone +352 26 783 787-686.

Extract from the law [article 2. 4 g]: Suppliers inform residential customers about alternative measures to interruption of supply sufficiently in advance of the planned interruption. These alternative measures refer to energy audits, energy advisory services, alternative payment plans, debt management advice or moratoriums with regard to interruption of supply, and do not imply additional cost for customers faced with an interruption of supply.

In the event of financial difficulty, we recommend that you contact the social services (” Office Social”) of your municipality to obtain the assistance provided for by the legislation in force. Please find the list of social offices in Luxembourg.
