Electricity and gas tariffs for March 2026: offers, discounts and how to choose
March is finally here. This month we celebrate the return of spring, yes; but also World Poetry Day. As the days start getting longer from now on, here is a little rhyme to help you save:
Check your electricity, your gas, your current tariff,
small gestures bring savings to your home, if you can.
Let your house breathe, let your wallet smile,
in every decision, harmony blooms for a while.
It’s time to look, to adjust, and to review,
and find the best tariff that’s right for you.
At Endesa, this March we bring you options designed so that your energy and your home rhyme with your well-being. Clear tariffs, designed for you to enjoy the season with no surprises on your bill. Because in March, every detail counts – and choosing the right tariff counts even more.

FAQs – Electricity and gas tariffs in March 2026
When is the best time to switch tariffs?
March 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 spring, electricity consumption changes, so it might be the right time to adjust your tariff to your new habits.
Many companies launch special promotions in spring with the mission of attracting new customers, like our March discounts on the Fixed 24h Online, Conecta, Conecta 3 Periodos, and Conecta Gas tariffs.
If you opt for a fixed tariff in March, 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, Endesa's 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’s 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 Promo 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.
And if what you want is a competitive price with zero hassle, then Conecta is your best ally: fixed price 24/7, no commitment and all your transactions online so everything is fast and easy. Ideal for those who value stability and convenience in their everyday life.
Still not sure? Our team of energy advisers is available to help you compare, understand, and choose the tariff that truly works best for you!
Start the season on the right foot by reviewing your electricity and gas tariffs to make sure they match your real needs. March is the ideal time to make decisions that will follow you throughout 2026: more savings, more efficiency and more peace of mind.
Because if there’s one habit that’s always worth keeping, it’s taking care of your energy – and your wallet. Here’s to a 2026 full of smart choices and even better savings!
