The best electricity tariffs for October 2025: Which one is right for you?

Remember:

• Prices shown do not include taxes (VAT, electricity tax, etc.).
• Endesa’s Dual Online Tariff is available exclusively for new customers.

Which electricity tariff should I choose in October?

Let’s explore three different scenarios:

• If you spend most of the day at home, especially during the hottest hours, and rely heavily on air conditioning, the Endesa Conecta tariff is your best option. Its stable 24-hour pricing lets you use your appliances without worrying about time-of-use charges or unexpected bill spikes.
• If you’re looking for an all-in-one solution, the Dual Online tariff is perfect for you. It combines electricity and gas under a single bill, making it easier to manage your contracts and giving you greater control over your energy expenses. With fixed pricing throughout the day and no long-term commitment, it’s ideal for those who value convenience, predictability, and the freedom to switch tariffs whenever they need.
• If you only need natural gas, the One Gas tariff is a simple, affordable, and hassle-free option. It’s designed for customers who already have an electricity plan with another tariff or provider but want to optimise their heating, hot water, or cooking costs. With a fixed price per kWh and no commitment, it’s a flexible choice that fits any household looking for efficiency with no strings attached.

Is it better to get a fixed or variable tariff?

If you prefer stability and want to avoid surprises during the back-to-school rush, a fixed-rate tariff can give you peace of mind, like Endesa's Conecta or One Gas tariffs. When you have high-consumption appliances, or children at home who use more electricity and gas at peak times, a fixed-rate tariff is the best option to protect yourself from price increases.

A variable-rate tariff, like those offered by Endesa: One Luz 3 Periodos can help you save if you are able to adapt your consumption. This includes using appliances at night, turning off lights and electrical devices that are not in use, and making children aware of energy saving habits (turning off the tap, switching off lights when leaving a room, and not leaving chargers plugged in, among others).

Tips to save on your electricity bill this October

• Use your heating in ECO mode and keep it at a moderate temperature.
• Take advantage of off-peak hours for laundry, cooking, or ironing.
• Review your contracted power—if it’s higher than you need, you’re paying too much.
• Consider no-commitment tariffs for greater flexibility.

FAQs – Electricity and gas tariffs in October 2025

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 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 promotions for autumn, aiming to attract new customers.
• In October, the use of heating and cooling 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 October, 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 stable pricing 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 clear 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.
