The price of my contract, the Tarifa One contract, may be updated on the first of January after contracting it, in accordance with the value of the real CPI (the latest general inter-annual Consumer Price Index officially published at the time of the update), as well as because of variations suffered by the current regulated components that are applicable to electricity and gas supplies, and with possible new changes that may be approved by law.
If there are changes in the price of your contract, they will be transferred on to the customer both if they are upward or downward. This type of modification is regulated and completely beyond Endesa's control, applying equally to the entire country and to all companies.
In addition, the price may be reviewed one year after contracting. This would happen in April or October of each year. If there are any changes, we will let you know a month in advance. Remember that at you can terminate the contract, contract another rate from Endesa or any other company any time.
