Do you have a fault?

At Lumisa as an energy trader, we focus our activity on the purchase of energy in the electricity market. The electricity distribution and maintenance lines are owned by the distribution companies.

For this reason, any incident in the supply is the responsibility of the distribution company. The distribution companies have customer service telephones in case of breakdowns where you can contact to solve any problem related to the supply electric.

If you have a breakdown at your supply point, we will provide you with the distributor's technical assistance telephones. If your distributor is not listed here, you will find it in the 'Faults' section of your invoice.
