The price may be updated on 1 January each year by the value of the actual CPI (last General Year-on-Year Consumer Price Index officially published at the time of the update), as well as for variations in the current regulated components that apply to electricity and gas supplies, and with possible new changes that may be approved by regulation.

In case of updating by the value of the CPI, the year-on-year CPI for November, published on the website of the National Institute of Statistics (https://www.ine.es/) will be used. The update will be made by adding the result of multiplying the CPI by the current prices to the previous prices. For more information, the year-on-year CPI for November 2021 was 5.5%, the year-on-year CPI for November 2020 was -0.8% and the year-on-year CPI for November 2019 was 0.4%.

Any changes in the regulated components applicable in the contract (upwards or downwards) will be transferred to the customer. These modifications are regulated, they are totally beyond Endesa's control and apply equally throughout Spain and to all companies.

The price may also be reviewed one year after contracting. If there were any changes, we would let you know one month in advance. Always remember that at any time you can terminate the contract or contract another tariff from Endesa or any other company without penalty.

If you get the Social Bonus, you should not apply for this tariff because you would lose it.

Once you have filled in the online contracting form and your application has been processed, it will take approximately 3 weeks to process your contract (if you were already with Endesa Energía the change is much faster).
