FAQs – Electricity and gas tariffs in October 2026

When is the best time to switch tariffs?

October 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 the arrival of autumn, electricity consumption changes, so it might be the right time to adjust your tariff to your new habits. 
• Many companies launch special promotions in autumn to attract new customers, like our October discounts on the Luz 24h Online, Conecta Luz, Conecta Gas, Gas Endesa Clientes, and Recarga en Casa Tariffs.
• If you opt for a stable tariff in October, it will help protect you from potential price rises in the coming 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., 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 remains stable 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 (Conecta 3 Periodos): Endesa’s Conecta 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.
