Many people have their electricity with one company and their gas with another. This means two different contracts, with bills arriving at different times and in different formats. In the end, it’s double the hassle. At Endesa, we don’t want you to waste your time, so we offer you the option to combine your electricity and gas into one single tariff. That way, you’ll have more time for what really matters to you and the peace of mind of knowing all your energy is in one place, well managed, and at a low price.

Choose the One Light + Gas Tariff, the combined gas and electricity tariff. With this tariff, you can enjoy a single price for both electricity and gas.

You’ll no longer need to worry about when electricity is cheaper – use electricity and gas whenever you want, with no surprises on the bill.

A tariff to simplify your management and easily combine your supplies. Unify your bills and take advantage of online billing by signing up for Endesa’s affordable electricity and gas tariff.

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.

If any changes, either upward and downward, are made to the regulated components applicable to the contract, these will be passed on to the customer. These types of changes are regulated and are entirely beyond Endesa's control. They apply equally across the Spanish national territory and to every provider. Additionally, the price may be reviewed after one year from the contract date. If any changes occur, you will be notified at least one month in advance. You may then choose to terminate the contract without penalty, switch to another Endesa tariff, or sign up with a different energy provider.

The fixed-price One Luz + Gas tariff combines what households demand most: price stability, freedom to switch whenever they want, and a bill without shocks. A competitive proposal in the current market.

It includes a fixed price per kWh for electricity and a fixed 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.

The main advantage is protection against changes in the wholesale market. With a fixed-price tariff, you know exactly how much you pay for every kWh, avoiding price spikes and fluctuations. It is ideal for households that want to plan their monthly budget without surprises.

It is suitable for any consumption level, but especially for moderate and constant usage, such as family homes or people who work from home. Price stability makes monthly spending more predictable, regardless of usage.

Yes. The price per kWh of electricity and gas remains stable throughout the contracted period, which lets you plan energy spending clearly. There are no quarterly changes, time bands, or market-linked variations.

You sign up 100% online, which speeds up the process and avoids unnecessary paperwork. You will need:

• Your personal details
• The supply address
• The electricity and gas CUPS numbers

You can activate the tariff in just a few minutes without calls or paperwork.

That will depend on the specific terms of your current contract. If you are already with Endesa on a different tariff, you can check in your Customer Area if this option is available for your supply point. 

The main difference is stability:

• PVPC and TUR depend on the market, so they go up and down constantly.
• The fixed-price tariff maintains a constant amount, which is recommended for households that prefer bills without shocks and controlled energy spending.

Yes, optionally. You can add services such as:

• Electrical and gas installation maintenance
• Repair of faults
• 24/7 assistance
• Payment protection insurance

These services are designed for those who want extra security and technical support.

From the Customer Area (app or web), you can:

• Check real-time consumption for your dual fuel tariff
• Access monthly comparisons
• Download your bills for both electricity and gas consumption
• View recommendations to improve efficiency

With a fixed price, this information lets you fine-tune your savings even further.

The tariff is linked to the supply point. When moving:

• It cannot be transferred directly
• You can sign up for it in your new home as long as you are a new customer at that supply point

The process is fast and totally online.

If you have a solar panel installation with an active self-consumption tariff, you cannot sign up for this tariff. However, at Endesa, we offer the Endesa Solar Tariff, tailored specifically for you.

Yes, for new customers: For electricity, a 10% discount on consumption will be offered for 1 year, and one month of free electricity consumption every year. The free month is equivalent to 720 hours of consumption and includes a 1-year commitment to the electricity contract. For gas, a 10% discount will be offered on the variable term (consumption) for 1 year. For joint electricity and gas contracts, a 20% discount will be offered on the variable term (consumption) for gas for 1 year. This promotion is not valid in Ceuta and Melilla.

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.
