What does it mean to register for digital invoicing?

When you activate digital invoicing you will receive your invoices by e-mail instead by post. And most importantly, we notify you that it is available before the bank charges you.

What are the main advantages of activating digital invoicing?
  • It is quicker:  What you used to receive by post will arrive a week earlier by e-mail. The bank will not have charged you yet, but you will already know everything on the invoice. 
  • More information and control:   In the e-mail you receive, without obliging you to click, you will see a breakdown of the amount to pay and details with regard to your consumption.
  • More savings: Digital invoicing enables you to know how many kWh you are using in each hour of each day. This will help you optimise your consumption and save on your next bills.
  • More ecological: Eliminating home visits increases energy efficiency and reduces CO2 emissions.
  • Also on your mobile phone/tablet:  You will have access to your bill from anywhere and at any time.
  • Free and no minimum duration: The digital invoice service is totally free and you can return to receiving it by post any time you like.
If I activate it and regret it, can I change my mind and go back to receiving it by post?

Of course you can. You can go back to receiving it by post at any time. All you need to do is to register or log in to the Client Area of endesa.com and from there with a single click you can deactivate the digital invoice service.

Do I have to pay for the digital bill?

No, it is free. Enjoying all the advantages of digitalisation will not cost you anything.

What requirements do I have to fulfil to become digitalised?

You only need to be an Endesa customer. All of our customers can become digitalised with just one click.

I like the idea of becoming digitalised... but I still want to receive the traditional bill.

No problem. When becoming digitalised you access a whole new universe of advantages, but you keep your traditional bill in PDF format, which is available instantly, without having to wait for the postman to deliver it.

Is a digital bill legally valid?

Yes. In the event of an incident or if you wish to make a complaint, a digital bill has full legal validity.

Is the electronic billing service safe?

Completely safe. It includes a digital signature that guarantees the authenticity of the issuer and the integrity of its content. Endesa has an electronic certificate from the Spanish Notarised Certification Agency that allows us to incorporate an advanced electronic signature on all of our bills.

GENERAL CONDITIONS OF ELECTRONIC BILLING

  1. PURPOSE

    The purpose of these general conditions is to regulate and facilitate electronic billing in favour of customers of Endesa Energía , SAU (hereinafter, Endesa Energía ) or third parties billed by Endesa Energía .

  2. CHARACTERISTICS OF ELECTRONIC BILLING

    The registration for electronic billing will be voluntary and free of charge for the customer and will mean they no longer receive their bill by mail (for services and products of Endesa Energía as well as from third parties billed by Endesa Energía ), as established in the following stipulations.

    1. The bills issued by Endesa Energía for the different services provided will be uploaded to the Customer Area of the ENDESA website in XML and PDF format. To access these bills, the customer must have access to the ENDESA Customer Area, accepting the conditions of the website. From the Customer Area, the customer can at any time view the bills on the internet in the same format as those bills would have had been sent on paper to their home (PDF format).
    2. Additionally, as an added value, Endesa Energía will be able to send messages to the customer by email in order to notify them of the availability of bill consultation. The availability notice allows, in addition to the on-screen display of the bill amount and the detail, the download of the electronic bill in PDF format, onto the user’s personal device.
    3. The possibility of consulting the electronic bill in ENDESA is not conditional on the sending and receiving of the availability warning message, which is only informative.
    4. Electronic billing is based on the use of an electronic signature system that guarantees the authenticity of its origin and the integrity of its content, in the terms covered by Royal Decree 1619/2012, of 30 November, by which the Regulation on billing obligations is approved. Endesa Energía has obtained a cualified electronic certificate, issued by SIA, which enables it to incorporate an advanced electronic signature into its bills.
  3. REGISTRATION FOR ELECTRONIC BILLING

    It will be understood that the customer gives his/her consent to be registered for Endesa Energía electronic billing by agreeing to this document.

  4. ENTRY INTO FORCE AND REVOCATION

    From the moment when the customer accepts and adheres expressly and fully to electronic billing, it will be applied for all their current valid contracts, and the general conditions detailed in this document will apply.

    The customer may withdraw from electronic billing at any time and return to the ordinary paper billing system, by communicating to Endesa Energía through the Customer Area of the Endesa Energía website or any of the available service channels.

  5. CUSTOMER RESPONSIBILITIES

    It is the Customer’s responsibility in all cases to notify Endesa Energía of any change in the email address to which they wish to receive the notices. In any event, non-receipt by the customer of said notice, either by an erroneous email address being provided to Endesa Energía , or for any other reason, will not mean that they no longer have electronic billing, once the customer has registered for it and not subsequently withdrawn from it.

    The Customer guarantees and is responsible for, in any case, the veracity, accuracy, validity and authenticity of the personal data provided.

  6. DATA PROTECTION

    The processing of personal data will be done in accordance with the Endesa Energía Data Protection Policy.
