The Cheapest Electricity Tariffs in 2025
One of the most common goals among our customers at Renovae Energy is to reduce their electricity bill without any hassle. To do that, choosing the right tariff is key. But in an increasingly complex market, how do you know which one is really the cheapest?
In this article we give you the keys to understanding today’s electricity tariffs and knowing which one best fits your consumption.
What types of electricity tariffs exist in 2025?
This year there are still three main types of tariffs:
- Fixed-price tariffs: you pay the same per kWh 24 hours a day.
- Time-of-use tariffs: the price varies depending on the time of day (peak, mid-peak and off-peak hours).
- Indexed tariffs: the price changes every hour based on the electricity market.
Which is the cheapest tariff for your profile?
There’s no single answer. At Renovae Energy we always analyse each home’s consumption profile before making a recommendation. But as a general reference:
- If you consume mostly at night: a time-of-use tariff may be the best option.
- If you have solar self-consumption: good surplus compensation is essential, along with a tariff that doesn’t penalise consumption during hours without sun.
- If you consume at all hours: a fixed tariff can give you stability, even if it isn’t always the cheapest.
What to look at when comparing tariffs?
Beyond the price per kWh, there are factors that greatly affect the final cost:
- Price of the contracted power
- Compensation for solar surplus
- Contract length and lock-in period
- Management costs or mandatory add-on services
How do you know if you could pay less?
At Renovae Energy we always recommend reviewing your bill with us. In many cases, we identify overcharges from excess contracted power or tariffs poorly matched to your consumption profile.
What’s more, if you have or plan to install solar panels, we help you find the best self-consumption tariff to maximise your savings.
Can we help you choose the best tariff?
We know comparing tariffs can be tedious. That’s why at Renovae Energy we do it for you. We study your consumption, analyse your habits and propose options tailored to your case.
It’s not just about paying less, but about paying a fair price. And that’s what we’re here for.
