How to Set Up Electricity in Spain in 2026

If you just moved to Spain or are about to rent your first flat or house, setting up electricity (“dar de alta la luz”) is one of the first practical steps.

The system can feel confusing: regulated market, free market, potencia contratada, change of titular, social bonus… This guide explains everything clearly and step by step.

You will learn:

• How electricity works in Spain
• What documents you need
• How to change the contract in a rental
• Regulated vs free market differences
• Which provider we recommend for expats

How the Electricity System Works in Spain

Spain has two types of electricity markets:

1. Regulated Market (PVPC)

• Government regulated tariff
• Price changes hourly
• Only available through specific suppliers
• Required if you want access to the “bono social”

This option is usually chosen by residents who understand hourly price fluctuations.

2. Free Market (Mercado Libre)

• Private pricing
• Fixed or indexed plans
• Promotions and discounts
• More predictable monthly costs

Most expats choose the free market because it is simpler and easier to manage.

Major providers in Spain include:

• Endesa
• Iberdrola
• Octopus Energy
• Repsol

When Do You Need to Set Up Electricity?

You typically need to act in one of these situations:

1. New Rental – Contract Already Active

This is the most common case.

Electricity is already connected. You only need to:

Change the contract holder (“cambio de titular”).

• No technician visit
• No installation fee
• Usually completed in 1–3 business days

2. Electricity Was Cut Off

If the apartment has no active supply:

• You must reactivate service
• You may need to pay reconnection fees
• Activation can take a few days

3. New Build Property

You may need:

• First activation
• Electrical installation certificate (CIE)

What Documents Do You Need?

In most cases:

• NIE or passport
• Spanish bank account (IBAN)
• Rental contract
• Property address
• CUPS number (electricity supply point code)

The CUPS number can be found:

• On a previous electricity bill
• Provided by the landlord
• From the current supplier

What Is Potencia Contratada?

Potencia contratada (contracted power) determines how many appliances you can use at the same time.

Typical values:

• Small apartment: 3.45 kW
• Medium apartment: 4.6 kW
• Larger apartment with air conditioning: 5.75 kW or more

If your power is too low, the breaker will trip.

If it is too high, you pay more every month in fixed costs.

Many rentals are slightly oversized, so it is worth checking.

How Much Does Electricity Cost in Spain?

Your electricity bill has two main parts:

1. Fixed cost (based on potencia contratada)
2. Variable cost (based on kWh consumption)

Average monthly bills in 2026:

• Small apartment: €40–€70
• Family apartment: €70–€120

Air conditioning use significantly increases consumption.

How to Change Electricity Contract in a Rental (Step-by-Step)

2. Find the CUPS number
3. Choose your provider
4. Submit ID, IBAN, property address
5. Confirm potencia contratada
6. Wait for confirmation

The change of titular usually completes within a few business days.

No technician visit is required if supply is active.

Regulated vs Free Market – Which Should You Choose?

Choose regulated (PVPC) if:

• You qualify for the social bonus
• You understand hourly price changes
• You actively monitor electricity pricing

Choose free market if:

• You want predictable bills
• You prefer fixed pricing
• You want easier communication and simpler plans

Most expats prefer the free market for convenience.

Common Mistakes Expats Make

Not Changing the Contract

If the electricity contract remains in the landlord’s name:

• You depend on them
• They could cancel it
• Billing disputes may arise

Always change the contract to your name.

Choosing Too Much Power

Accepting 5.75 kW without checking your real needs increases fixed monthly costs.

Ignoring Contract Terms

Some providers include:

• Minimum commitment periods
• Early termination penalties

Always review the conditions.
