What do I have to do to contract the One Tariff service?

It is very easy to sign up for Endesa's One Tariff. You can begin the process from our catalogue of products, via campaigns or promotions, from the product comparison section or from your “Customer area”.

The online process in 3 simple steps:

  • Learn about the products and promotions on offer then choose the one that best suits your requirements.
  • Check the general and specific terms and conditions of the contract.
  • Access and complete the fields in the relevant online contract form.

We will guide you through the contract process:

"Your details": Allow us to get to know you better so we can offer you the best service. Please provide your personal details and your mailing address.

If you are already an Endesa customer, if you prefer, we can recover your details. This makes the online contract registration process even easier.

“Your supply”:in this step, you must indicate:

  • The name of your reseller company..
  • Your CUPS number or the address of your Supply Point.
  • If you are not the contract titleholder, do not worry, we can change the titleholder details when it comes to signing up for the service.

Your power: choose the power that best suits your requirements. You may also use our power calculator.

Summary of your order: You can view the summary of your contracted products.

Your payment details: Please add the bank account number to set up the direct debit payment for your bills. If we do not already have your bank account registered, we will attach a direct debit order.

Your documentation: We will inform you if you need to attach the Energy Efficiency Certificate (CIE). You will only need to send this for power increases that exceed the maximum authorised power (PMA, in Andalusia is 1.5 PMA) increases for CIE that are over 20 years old and titleholder changes with CIE that are over 20 years old. If you do not have the required documentation available straight away, you can send it to us by email or ordinary post: recepcioncie@endesa.es

Your confirmation: You will see a screen with all the details you have provided. You can follow the contract process via My Endesa.

Once you have completed the contract process, you will be able to view the details of your request; we will inform you of the contract number and send an email to the address you have provided, where you can download the general and specific terms and conditions accepted beforehand.
