Remember that before making a claim, you can check the most frequent questions about your contracts and help you more easily and quickly.

If you have not received your invoice, you can join Lumisa by registering in the Client Area , where you can view all your invoices already issued and download them whenever you want. There are several reasons why you may not have received your invoice. One of them is that the invoice has not yet been issued. If, on the other hand, it has been issued:
  • Digital invoice: if you have activated the email delivery service, it is possible that it is in the spam section. You can also check in your Client Area that the email address where we are sending you the invoice is correct.
  • Wrong postal address: check that the address provided is correct and complete.
  • The contract is not active: invoices are only issued for active contracts.

Your reading is probably an estimate, since your meter could not be accessed. To regularize the reading, you will need to provide us with the reading by calling us at 900 811 473 or via email, also indicating your CUPS number.

  • Excessive consumption due to a seasonal peak (air conditioning, heating...)
  • Estimated reading
  • Several months billed at the same time
  • Discount not applied
  • Penalty for excess power in the case of customers with a 3.0A rate

If you have doubts about any concept of your invoice, we have a faqs where we explain it in detail.

By bank teller or transfer, the payment of an invoice is not made until 3 working days have passed.

The non-payment of any invoice will accrue default interest, as well as administrative management expenses generated by the subsequent claim to the Client of the unpaid debt corresponding to an amount of thirty-five euros (€35), as established for it in the law against late payment Law 3/2004 of December 29. In addition, in the event of two or more consecutive or alternate returns due to non-payment of invoices, the invoice will be sent to the address provided by the Client for payment in any of the entities provided by LUMISA, transferring to the client the bank expenses caused by the return of the same. You can consult section 6.5 of the General Conditions.
In accordance with the provisions of European Law, we inform you of the existence of the online dispute resolution platform of the European Commission, accessible at the following link:
