Why is Black Friday a good time to switch or sign up for an electricity or gas tariff?
Although there is no mandatory official review, many suppliers update prices or launch promotions in autumn, most notably for Black Friday. This makes it a good time to review your contract, adjust your contracted power, and compare available tariffs, especially if your consumption is starting to increase with the change of season.

FAQs – Electricity and gas tariffs in November 2025
When is the best time to switch tariffs?
November is usually a good time to switch your electricity tariff. It offers several advantages that make it an ideal opportunity to review your contract:
- With cooler temperatures, electricity consumption changes, so it might be the right time to adjust your tariff to your new habits after the summer break.
- Many companies launch special autumn promotions to attract new customers, like our Black Friday discounts on the One Luz, One Gas, and One Luz + Gas tariffs.
- In November, the use of climate control systems is typically moderate. This makes it an ideal month to evaluate your tariff without the extremes of summer (regular use of air conditioning) or winter (heating).
- If you opt for a fixed-rate tariff in November, it will help protect you from potential price rises in the winter months.
Taking advantage of these conditions can make a big difference on your bill. What if I have a commitment period?
What if I have a commitment period?
If your current tariff includes a commitment period, check the terms and conditions. Some penalties are low enough that switching could still save you money.
Which tariff is best if I have heating or air conditioning?
In this case, the Endesa Conecta Tariff is the best option. It's perfect for homes with air conditioning as it offers a stable price 24 hours a day, so you can use it whenever you need to without worrying about time bands.
What’s the difference between stable and time-of-use tariffs?
When choosing an electricity tariff, it’s important to understand how pricing is structured. At Endesa, you can go for a stable tariff (e.g., Endesa Conecta) or a time-of-use tariff (e.g., Tempo 3 Periodos). Both have advantages but are designed for different usage profiles.
- Stable tariff (Endesa Conecta): The price per kWh is fixed all day long, offering simplicity and predictability. You don’t need to watch the clock or change your habits. So, it’s ideal if you want a sense of security and full control over your bill. The drawback? You won’t benefit from lower off-peak pricing.
- Time-of-use tariff (Tempo 3 Periodos): Endesa’s Tempo 3 Periodos tariff is designed for those who can adapt their energy use to the times of day when electricity is cheaper. This tariff divides the day into three time bands: off-peak, shoulder, and peak hours. To make the most of it, it’s important to understand your energy habits and, if possible, shift some of your consumption to off-peak hours. This can result in significant savings on your monthly bill, especially if you use high-consumption appliances or have flexible schedules.
Expert opinion
At Endesa, we’re here to help you choose the tariff that best suits your needs. If you're looking for peace of mind, One Luz or One Luz + Gas are safe options. If you prefer to save at specific times of day, Tempo 3 Periodos offers flexibility and ongoing discounts. And if you only need gas, One Gas is an efficient solution.
