The Luxembourg legislation regarding the organisation of the electricity and natural gas markets does not contain any specific provisions relating to vulnerable customers. Instead this is ensured by the various social legislations.
In Luxembourg, if a consumer is unable to meet his or her domestic energy costs and meets the eligibility requirements for social assistance, the competent social welfare office may initiate, at the request of the customer, an assistance procedure to guarantee them a minimum energy supply. This minimum supply guarantee includes the right to be supplied with energy for adequate heating, cooking and lighting.
If you think you qualify for social assistance, you should contact the social welfare office of the municipality where you live. On the basis of the information they receive regarding your situation, the social welfare office will then assess the most appropriate ways to deal with the problem of financing your energy supply.
You can also get in touch with the municipal administration of your place of residence, the Ministry of Family Affairs or other non-governmental organisations who are active in the social domain to find out about support, such as the Ligue Médico-Sociale or Inter-Actions asbl. They can monitor your situation on a regular basis, even if you are over-indebted or in financial difficulty, for example by drawing up a weekly spending plan.
Also, depending on your situation, you may be entitled to a cost-of-living allowance or the energy premium (only for 2022) through the Fonds national de solidarité (www.fns.lu). You can find more information here.
