FAQs – Electricity and gas tariffs in January 2026

When is the best time to switch tariffs?

January is usually a good time to switch your electricity tariff. It offers several advantages that make it an ideal opportunity to review your contract:

• As cold weather arrives, 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 winter promotions to attract new customers, like our January discounts on the Conecta Luz, One Gas and Conecta Luz + Gas tariffs.
• Winter typically brings increased use of heating and climate-control systems, making January a perfect time to assess your plan.
• If you opt for a fixed-tariff plan in January, 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?

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.
