Frequently Asked Questions

The One Luz + Gas tariff is an electricity and gas tariff to simplify your management and combine your supplies easily. It is two energy supplies at a single rate, without complications and with the peace of mind of having a fixed price that will allow you to forget about when you use your appliances. All your energy (light, heating, hot water) can cost the same whenever you use it, and it will cost you very little.

Below we detail the prices (taxes included) of the One Luz + Gas rate, one of the most competitive options to combine your electricity and gas supply:

Many people get their electricity from one company and gas from another. This implies two different contracts, with different bills arriving at different times and in different formats. In the end, your attention is divided in two different directions. At Endesa we don't want you to waste your time and this is why we offer joining your electricity and gas together in a single rate. This way, you will have more time to devote to what really interests you, and you will live with the carefree knowledge that all your energy is in one place, well managed and at a cheap price.

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.

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

There are no penalties if you decide to leave. There are only specific conditions for some promotions or temporary special offers. Don't worry, we will let you know if this is the case.
