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 with 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 to the previous prices the result of multiplying the CPI by those prices. For more information, the year-on-year CPI for November 2023 was 3,2%, the year-on-year CPI for November 2022 was 6,8%, 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 contract this tariff on our website (www.endesa.com), there are no penalties if you decide to cancel. If you contract this tariff through another channel, we will be able offer you additional advantageous conditions if you accept a commitment to a minimum duration. There is no need to worry, we will let you know. If you accept it, a commitment to a minimum duration means that should you leave before the end of the first year of the contract a penalty equal to 5% of the estimated outstanding billing will be applied. This estimated outstanding billing is calculated by multiplying the non-discounted contract price at the time of termination by the estimated energy outstanding until the end of the first year of the contract.

If you have another rate, other than the Tarifa One rate, you can switch to the Tarifa One rate without any problem. However, if you have already contracted the Tarifa One rate, you cannot unsubscribe in order to contract it again.

The Tariff One contract is for one year, automatically renewable.
