On the resulting amount, VAT (21%), IGIC (Canary Islands: 0% or 3%, and 7% as applicable) or IPSI (Ceuta and Melilla: 4% or 1% as applicable) will be added.

Online rate available for new gas contracts with Endesa Energía.

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.

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.

No, this tariff is only available to new customers. If you are already an Endesa customer, we have a lot of exclusive benefits for you.

The 24h Online Fixed Light + Conecta Gas Tariff features one of the lowest prices on the market for new customers, for both electricity and natural gas. It offers a stable price all year round, with no time bands or seasonal variations. It is designed for households seeking simplicity, direct savings, and totally digital energy management.

The 24h Online Fixed Light + Conecta Gas Tariff optimises operating costs by focusing on a 100% online model, which allows those savings to be passed directly to the customer. Its simplified price – with no mandatory services or additional conditions – is what makes it one of the most competitive options on the market.

That will depend on your consumption profile. The PVPC (electricity) and TUR (gas) are linked to the wholesale market, so they fluctuate constantly.

It is a solid alternative for those who prioritise stability and sustained savings.
