Best Electricity and Gas Companies
In Spain, consumers can choose to buy electricity and gas on the regulated market or on the free market. However, freedom of choice has now become a maze that is very hard to find your way out of when choosing the supplier that offers the energy rates and services best suited to each customer's specific electricity and natural gas needs. If you've made it this far, you're in luck, because the free comparison tools and apps we put at your disposal are the best compass for quickly finding the way to savings on your next bills without falling for offers with prices that are a trap or tripping over the small print that hides the conditions least favourable to you. Find out whether your supplier deserves a second chance or whether it's time to get moving and get your new energy at the best price.
Which electricity company is cheapest in 2023?
Since the summer of 2022, people have been talking a lot about the “Iberian exception” when referring to the Spanish electricity market, which consists of capping the price of natural gas used in energy production. However, the same name would also describe very well how exceptional Spain's free energy market is: more companies operate in it than in any neighbouring country, with more than 700 active electricity suppliers and more than 250 companies in the case of gas.
That's why finding the cheapest supplier in a list of almost 1,000 companies has become the modern version of “finding a needle in a haystack”, especially when you don't have the help of a tool like ours, which lets you compare the main companies on the market for free, based on our experts' research and consumer ratings.
Because we know how important it is right now for any family's or business's budget to pay less for electricity and natural gas, we analyse how market prices have evolved this year to bring you a ranking of the electricity companies with the best offers.
Which electricity company does the OCU recommend?
In any decision that affects the use of basic services, for example when choosing your home energy supplies, it's also a good idea to check other objective and reliable sources to make the right choice. Consulting highly reputable sources, such as the information provided by the Organisation of Consumers and Users (OCU) is always highly recommended. The OCU provides its members with services aimed at saving money on consumption, such as tools for comparing products; it also publishes studies and carries out satisfaction surveys among its users.
As an independent organisation, the OCU does not recommend any electricity company, but it does publish reports on its website comparing the cheapest energy rates, as well as practical guides and very useful tips for improving both savings and energy efficiency in Spanish homes.

Frequently
Asked Questions
What is the difference between the regulated market and the free market?
Any consumer can choose to buy their electricity and natural gas supply on the regulated market or the liberalised one. The PVPC rate can only be taken out with a reference supplier authorised by the Government and is limited to power below 10 kW. This rate has a protected, non-negotiable price that is subject to daily changes in the wholesale market.
By contrast, the free market is different because it is the companies that set the price per kWh, without changes during the term of the contract, and with many options of of sale that don't exist on the regulated market, such as discounts for switching supplier or different types of rates to better meet the particular needs of their customers.
What is the difference between a supplier and a distributor?
The electricity and natural gas distributors are the companies that carry energy to homes to give access to the supply points. Their geographical allocation is decided by the Government, so people will be assigned the one that corresponds to their address according to the network of distribution.
For its part, the supplier is the company that provides the end customer with the electricity and gas supply at their home or business premises. Users can choose the company they prefer and also sign up for other additional services such as installation checks and urgent breakdown repairs, among others.
Which are the reference electricity companies in Spain?
According to the latest CNMC update, they are: Energía XXI, Comercializadora Regulada Gas & Power, Curenergía, Aser, Comercializador de Referencia Energético, S.L.U., Teramelcor S.L., Régsiti Comercializadora Regulada and Energía Ceuta XXI.
Which electricity companies are there on the free market in Spain?
According to the CNMC register, at the end of 2022 there were 713 active electricity suppliers in Spain. However, it is still a sector dominated by large corporations such as Endesa, Iberdrola, Naturgy o Repsol, alongside which other interesting options are emerging, such as Holaluz and Lucera. None of them can be missing from our comparison tool because we always want to offer the most satisfactory answer to each person's different energy needs.
