The price may be updated on 1 January each year based on the actual CPI (latest officially published year-on-year Consumer Price Index at the time of the update), as well as any changes to current regulated components applicable to electricity and gas supplies, and any potential new changes that may be approved by regulation.

In case of an update based on the CPI, the year-on-year CPI for November will be used. It is published on the National Statistics Institute website. The update will be made by adding the result of multiplying the CPI by the previous prices to the existing prices. For more information, the year-on-year CPI for November 2025 was 3.0%, the year-on-year CPI was 2.4% for November 2024, 3.2% for November 2023, 6.8% for November 2022, 5.5% for November 2021, -0.8% for November 2020, and 0.4% for November 2019.

In the event of an update based on Adjustment Services, a 'Reference Value for Adjustment Services' of €17/MWh is established, as well as a tolerance band delimited by a minimum value and a maximum value called: "Lower Reference Value for Adjustment Services': €14/MWh.  'Upper Reference Value for Adjustment Services': €20/MWh. These values will be updated on 1 January each year, taking into account the 'Actual Value of Adjustment Services' for the months between December of two years prior and November of the previous year (both months included), published by the System Operator (REE) on the website https://www.esios.ree.es/es/descargas in the file PVPC_DETALLE_DD. The result of this update may be upward, downward, or neutral (if the actual value remains within the tolerance band).

Should there be any changes to the regulated components applicable to the contract, these will be passed on to the customer, whether they result in an increase or a decrease. Such changes are regulated and are entirely beyond Endesa’s control; they apply equally across the whole of the country and to all energy suppliers. In addition, the price may be reviewed one year after the contract is signed. Should there be any changes, we will notify you one month in advance and you will be able to terminate the contract without penalty, or switch to another tariff with Endesa or any other supplier.

Light 24h Online + Gas Endesa Tariff combines what households demand most: stability, freedom to switch whenever they want, and a bill without shocks. A competitive proposal in the current market.

It includes a stabled price per kWh for electricity and the same price per kWh for gas all year round, with no time bands or seasonal variations. It is a tariff designed for those seeking stability, predictability, and total control over spending on both electricity and natural gas.

Although Light 24h Online + Gas Endesa Tariff is a simple tariff, it includes full access to the PARA TI loyalty programme, where you can:

• Collect points with every bill you pay.
• Redeem them for direct discounts on future electricity or gas bills.
• Access exclusive prize draws and promotions from partner companies.

Key differentiator: Despite being a digital tariff with no added extras, it allows you to benefit from Endesa's loyalty ecosystem from the very first month.

For new customers only: when you sign up for the Endesa 24h Online Electricity + Gas tariff, you’ll enjoy:

• 10% discount on your electricity consumption for the first year + 20% discount on the variable gas charge (10% for 1 year and 10% indefinitely)

In general, our tariffs do not include a commitment period. However, in some cases we may offer you additional advantageous conditions linked to your acceptance of a commitment period, so you can enjoy those benefits.

If the tariff includes a commitment period, we will clearly inform you before you sign up. If you accept the commitment and decide to cancel before completing the first year, a penalty will apply equivalent to 5% of the estimated amount of energy pending supply until the 12 months from the start date are completed. This calculation is based on the contract price without discounts.

If the change is made after 12 months have passed, there will be no penalty, nor if you switch between tariffs within Endesa Energía.
