How does the price of my One Tariff contract change?

The price of the One Tariff contract is updated on the 1st of January after you have contracted the service with the real CPI value (Last inter-annual rate for the general Consumer Price Index published officially at the time of the update) and by variations to the current regulated components that are applicable to electricity and gas supplies and any possible new regulatory changes that may be approved in the future.

If there are any changes to the price of your contract, these shall be transferred to the customer upwards or downwards. These types of modifications are regulated and beyond the control of Endesa and are applied throughout Spain and to all companies.

In addition, the price may be reviewed after one year of the contract. This would take place in April or in October of each year. If there were any changes, we would inform you of these at least one month before. Remember that you can terminate the contract at any point and contract another Endesa tariff or that of any other company.
