Key Takeaways
- The biggest providers — Endesa, Iberdrola, Naturgy, Repsol — are not automatically the best value. Dozens of smaller suppliers often offer more competitive tariffs; the right choice depends on kWh price, fixed standing charges, and whether time-of-use pricing suits your consumption pattern.
- Compare total monthly cost, not just the per-kWh headline rate. A supplier advertising €0.13/kWh with €15/month in fixed charges can be more expensive than one at €0.16/kWh with €5/month standing charges, depending on how much you use.
- Switching is capped at 10 working days by law (Real Decreto 88/2026, since February 2026) and your new supplier handles the process — you don’t need to contact your current supplier. You’ll need your CUPS number (on your electricity bill) to initiate the switch.

Individual Provider Reviews
We have published detailed, honest reviews of every major electricity provider available on the Costa del Sol. Each review covers tariffs, English support, strengths, weaknesses, and what readers have reported about their experience.
English-language support: what we can and cannot confirm
English support is the single thing our readers ask about most, and it is also the hardest to verify. Almost no Spanish supplier publishes a clear statement of which languages it handles, and those that do usually publish it for existing customers rather than for people signing up. We label each claim by how strong the evidence is: published means the supplier states it itself; reported means readers told us, which is evidence about one call on one day, not a company; unverified means we cannot support the claim and are checking it with live calls. Last checked September 2026.

Frequently Asked Questions
How much does electricity cost in Spain?
The average Spanish household pays EUR 80-150 per month for electricity. On the Costa del Sol, summer bills can spike to EUR 200+ due to air conditioning. The regulated PVPC tariff averages EUR 0.10-0.20 per kWh depending on the time of day.
What is the PVPC tariff in Spain?
The PVPC (Precio Voluntario para el Pequeno Consumidor) is the regulated electricity tariff with hourly pricing that varies throughout the day. It is cheaper during off-peak hours (midnight to 8am) and most expensive during peak hours (10am-2pm and 6pm-10pm).
Should I choose PVPC or a fixed-rate tariff?
PVPC works well if you can shift consumption to off-peak hours (running dishwashers and washing machines at night). Fixed-rate tariffs offer budget predictability but are typically 10-20% more expensive overall. For most expats new to Spain, a fixed rate reduces bill shock.
How do I switch electricity provider in Spain?
Contact your chosen new provider with your CUPS code (on any bill) and they handle the switch. It takes approximately 2 weeks. There are no switching fees or penalties. Your supply is never interrupted during the change.
What is the potencia contratada?
The potencia contratada is your contracted power capacity in kW. Most homes have 3.45-5.75 kW. If your appliances exceed this, the breaker trips. You can adjust it through your provider but higher capacity means a higher fixed daily charge.
