One Luz Tariff: tariff with a fixed price per kWh

On the occasion of Black Friday, we are organising a draw for 15 LG SmartTV 4K OLED 55" TVs.*

*Promotion valid on the occasion of Black Friday for electricity and gas at Endesa Energía S.A. See conditions.

The One Luz tariff guarantees that the electricity you use is cheaper because a fixed price is set per kWh every month. Designed for those who use electricity in a stable way over the course of the entire day, or for those who don't want to worry about what time they use the most electricity.

With the One Luz tariff, you don't have to worry about when your electrical appliances consume electricity, as it costs you the same whatever time of the day or night you use them. Putting clothes to wash first thing in the morning will cost you the same as if you put them to wash at noon. You don't have to worry about the time any more.

Want to know how much each kWh costs so you can save energy?

You needn't worry any more, rather than charging by time of the day, the One Luz tariff involves a fixed, stable price per kWh. Designed for those who don't want to worry and know their bill will be cheaper.

Quick, easy and simple: all the kWh you consume will cost the same, you no longer have to worry about saving on electricity consumption: the One Luz tariff is the cheapest electricity tariff. In your bill, we multiply the kWh you have consumed by the competitive One Luz price. And that's that, no more complications.

As it is a 100% online tariff, you' can manage it all online, from arranging it to managing it, offering you much lower prices than traditional electricity tariffs and you'll save time with Endesa online billing.

If there are changes in the price of your contract, they will be transferred on to the customer both if they are upward or downward. This type of modification is regulated and completely beyond Endesa's control, applying equally to the entire country and to all companies.

In addition, the price may be reviewed one year after contracting. This would happen in April or October of each year. If there are any changes, we will let you know a month in advance.

Endesa One tariffs have no minimum term clause. If you're not convinced, you can change anytime. There are no penalties if you decide to cancel either.

Minimum terms only apply to certain promotions or special temporary offers. Don't worry, we'd let you know in that case.
