Iberdrola guideIberdrola Spain in English: what to know before you choose
By Linus Palmqvist, Head of Operations Reviewed by Simon Nilsson Last reviewed Iberdrola is a major incumbent with huge English-search demand, but it is not English-first. Settlewell can help you compare Iberdrola and your other options in English.
Is Iberdrola right for you?
Iberdrola can be a valid large-provider option, but the tariff menu is deep and the English experience is not as simple as the search demand suggests.
Choose Iberdrola if
- You want a major incumbent with broad infrastructure and many tariff styles.
- You are comfortable comparing options carefully before choosing.
- You want Iberdrola considered alongside other providers in English.
Look elsewhere if
- You want an English-first provider journey.
- You are eligible for Bono Social and may need to stay on PVPC.
- You find complex tariff menus and add-ons hard to evaluate.
What you choose, and what you cannot choose
Spain splits electricity into two jobs. The comercializadora is the retailer that bills you. The distribuidora is the grid company that owns the wires and meter; you cannot choose it.
You cannot choose the grid
i-DE in many central, northern and eastern areas. i-DE is assigned by address where it is the local distributor; choosing Iberdrola as retailer does not change the grid company.
Regulated route
Curenergía is the group route for PVPC, Spain's government-regulated electricity price, and Bono Social, a government discount for low-income households, when you are eligible.
Choose your route
Iberdrola is worth comparing, but Settlewell does not frame this as contracting Iberdrola for you.

What to have ready
Gather these details before you start, whether you do it yourself or ask Settlewell to do it for you.
Iberdrola has a deep menu, so the preparation step is about avoiding the wrong tariff and wrong market route.
CUPS
The permanent code that identifies your home's electricity supply point. It is on any bill.
Holder and ID details
ID document, CUPS/address, IBAN and ideally a prior bill.
IBAN
Your bank account number for direct debit.
Potencia contratada
The amount of power, in kW, your home can draw at once. Check it before accepting the setup unchanged.
Provider-specific tips
- Document fit: Iberdrola cites an identity document, CUPS/address, IBAN and ideally a prior bill. Passport-only is not explicitly confirmed.
- Property fit: Check whether you need free-market Iberdrola or regulated Curenergía. Do not leave PVPC if you rely on Bono Social eligibility.
English support reality
Iberdrola can work in English through some routes, but it is not an English-first household provider.
Workable English routes exist, but it is not English-first like the demand suggests.
What the provider can do
Iberdrola can work in English through some contact routes and international-area offices, but it is not as simple as an English-first provider journey.
Where Settlewell fits
Settlewell is the English layer for setup and comparison. Iberdrola is not affiliated with us.
What still belongs to the distributor
Power cuts, meter problems and some activation steps belong to the grid company for the address, not to the retailer you choose.
Compare before you commit
If your real need is English support, Endesa and Octopus may fit better. If you need gas, compare Naturgy.

Linus moved from Sweden to Málaga in 2021 and set his own home up here, so most of this he has already done the hard way once. Before Settlewell he spent years at Workwide, the cross-border recruiter that has helped over 10,000 people into jobs abroad, latterly as its Head of Recruitment and Operations. He speaks Spanish, lives in Málaga with his partner, and spends his days on the phone to Spanish providers.
