Electricity comparison for expats
The best electricity providers in Spain, compared in English
By Linus Palmqvist, Head of Operations Reviewed by Simon Nilsson Last reviewed No fixed prices and no fake universal winner. Compare providers by English support, regulated-route needs, the grid company reality, documents and best fit.
Best pick for each need
Start with the problem you need to solve. Then check the address and documents before treating any provider as final.
Octopus EnergyBest all-round pick for English-speaking newcomers
Modern green challenger with clean terms and good English-language service.
EndesaBest big-provider English route
Major incumbent with the clearest official English-capable customer line.
NaturgyBest electricity + gas route
Worth comparing when the property has mains gas as well as electricity.
IberdrolaBest big-provider comparison case
Huge incumbent with strong English-search demand, but not an English-first journey.
Side-by-side comparison
Prices change too often to list safely, so this comparison focuses on service reality and setup risk. PVPC means Spain's government-regulated electricity price. Bono Social means a government discount for low-income households.

What 'cheapest' actually means in Spain
Spain’s household market average is 0.2669 €/kWh including taxes and levies, and 0.184 €/kWh before taxes and levies. The general VAT reference is 21%.
Household band DC (2,500-4,999 kWh/year), all taxes and levies included, second half of 2025. Dataset updated 12 Aug 2026. General VAT rate applies to household electricity since 1 January 2025.
Figures as of . Source: Eurostat, Agencia Tributaria.
The average is historical context, not an offer you can sign up to. A low headline kWh rate can lose its advantage through a higher standing charge, unsuitable time periods or services you do not need.
Energy term
The energy term charges for the electricity you use. Compare your consumption pattern with the plan’s flat or time-based terms, including what happens when the offer renews.
Potencia term
Potencia is the capacity available when appliances run together. Its standing charge continues even when consumption is low, so the inherited setting deserves a separate check.
Regulated charges and taxes
Network tolls, system charges and electricity tax affect the total. Check whether the quoted supply terms already include regulated costs before adding them again. Meter rental and optional services also need attention.
VAT
VAT applies to the taxable subtotal, not just the energy line. Compare offers on the same tax basis and check the treatment on the actual bill.
Head to head
How to choose
Choose in this order, not by a single tariff headline.
- 1
Check whether the home already has electricity and a CUPS, the permanent code that identifies your home's electricity supply point. Without it, you may be closer to alta de luz, switching a supply on or activating a new one, than a simple switch.
- 2
Separate comercializadora from distribuidora. The comercializadora is the retailer that bills you. The distribuidora is the grid company that owns the wires and meter; you cannot choose it.
- 3
Decide whether PVPC, Spain's government-regulated electricity price, or Bono Social, a government discount for low-income households, could matter.
- 4
Check documents before provider preference. Passport-listed and passport-unconfirmed routes are not the same.
- 5
Compare by total fit, not a headline tariff. Potencia contratada, the amount of power in kW your home can draw at once, taxes, regulated charges and add-ons can change the real bill.

He speaks Spanish, lives in Málaga with his partner, and spends his days on the phone to Spanish providers.
