Electricity head to head
By Linus Palmqvist, Head of Operations Reviewed by Simon Nilsson Last reviewed Two big Spanish retailers, one real difference for a newcomer: Endesa has a customer line that speaks English, Iberdrola mostly does not. The rest comes down to the plan you pick and how you like to manage it.
Compare the same service and contract questions for each provider. This is a fit comparison, not a price ranking. Check the exact address before choosing.
Both sell free-market electricity contracts and both are everywhere in Spain. Neither is cheaper by default. What you pay depends on the plan, the contracted power and how you use electricity, not on the logo.
For someone who has just arrived, the difference that matters is support. Endesa publishes an English customer line and lists passport as an accepted ID. Iberdrola is a Spanish-first company that many newcomers use happily, but expect to do the talking in Spanish or bring someone who can.
Endesa's customer line assists in English and Catalan around the clock. That is the channel you will actually use when a reading looks off or a payment bounces, and it is the clearest English route among the old-line providers.
Iberdrola has English-speaking staff in places, but its household journey, app and letters are in Spanish. It works if you can read a bill in Spanish or have help. If you cannot, this is the page's one strong steer.
Neither brand's normal contract is the regulated PVPC tariff. Each group runs a separate regulated retailer for that: Curenergía in the Iberdrola group, Energía XXI in the Endesa group. If you qualify for the bono social discount, that is the route, and it works the same way for both.
If the home already has an active contract, you do a holder change: the contract moves into your name and the electricity never goes off. Both retailers handle that. Iberdrola has a dedicated holder-change flow; Endesa does it through its contract support and app.
If the supply is cut, activation goes through the grid company for the address, whichever retailer you choose. Have the CUPS and the meter reading ready either way. Check the exact address before you assume a date.
Both sell plans with certified renewable origin and both publish how that certification works. Read it on the specific plan, not the brand. The label on your bill tells you what your contract delivers; the group's power stations do not.
The previous occupant chose the contracted power, and it is charged daily whether you use electricity or not. Both retailers let you change it: Iberdrola through your online account, Endesa in the app. Do it after the holder change is confirmed, and check what you run at the same time before going lower.
