How to Change Company: Changing Your Electricity Company as a Tenant in Spain

If you rent a property in Spain, you may be wondering whether you can change company when it comes to your electricity supplier. The short answer is: it depends on whose name the contract is in.

Spanish law is clear on this, but many tenants and landlords misunderstand how it works. Here is what you need to know.

1. The Key Rule: Who Is the Contract Holder?

Under Spanish electricity regulations, the contract holder (titular del contrato) is the person legally responsible for the supply contract.

That person has the right to:

• Change company (switch electricity provider)
• Modify the tariff
• Change contracted power (potencia)
• Cancel the contract

If the electricity contract is in your name, you are free to change company whenever you want. The landlord cannot stop you.

If the contract is in the landlord’s name, you cannot legally change company yourself. Only the contract holder can do that.

This is not about tenancy law; it is about energy contract law.

2. If the Contract Is in Your Name

If you are the registered contract holder:

• You can change company at any time.
• There is no supply interruption during the switch.
• The process normally takes 3 to 7 working days.
• You do not need the landlord’s permission.

The only limitation would be if you signed a tariff with a fixed-term penalty clause, which is rare in standard residential contracts.

In practice, most tenants in Spain simply request a cambio de titular when they move in. Once the contract is transferred, they are free to choose any supplier in the open market.

3. If the Contract Is in the Landlord’s Name

This is where confusion starts. Some landlords prefer to keep the electricity contract in their own name and then charge the tenant:

• A fixed monthly amount
• Or the exact bill amount
• Or sometimes cash reimbursement

Legally, this is allowed. However, if the landlord remains the contract holder:

• The tenant cannot change company.
• The tenant cannot change tariff.
• The tenant cannot adjust contracted power.
• The tenant has no direct control over the electricity contract.

In this situation, if you want to change company, you must first request a change of contract holder (cambio de titular).

4. Can a Landlord Refuse a Change of Contract Holder?

In most standard long-term rental contracts (arrendamiento de vivienda habitual under the Ley de Arrendamientos Urbanos), utilities are typically transferred to the tenant.

If your rental agreement states that utilities are your responsibility, it is reasonable to request that the contract be put into your name. If the agreement clearly states that electricity remains in the landlord’s name, then you agreed to that arrangement when signing.

Always check your rental contract before making assumptions.

5. What a Tenant Should Do

If you want to change company, follow this practical approach:

Step 1 – Check the Bill Look at the latest electricity bill and confirm:

• Who is the contract holder?
• What tariff is being applied?
• What contracted power (potencia) is set?

Step 2 – Review Your Rental Agreement Check whether the contract states:

• Utilities must be transferred into your name
• Or remain in the landlord’s name

Step 3 – Request a Change of Titular (If Needed) If the contract is not in your name and you want control, request a cambio de titular from the current supplier.

This usually requires:

• Rental contract
• ID (NIE or passport)
• Bank account details (IBAN)
• CUPS number (found on the bill)

Once the contract is in your name, you are free to change company.

6. Is There Any Risk in Changing Company as a Tenant?

From a supply perspective, no. Electricity distribution is handled by the regional distributor, not the commercial supplier. Changing company does not affect:

• The physical connection
• The meter
• The quality of supply

What does change is:

• The price per kWh
• The fixed power charge
• The billing terms

---

7. Should You Change Company as a Tenant?

That depends on:

• How long you plan to stay
• Your consumption pattern
• The current tariff structure
• The contracted power level

For short stays, it may not be worth the effort. For long-term rentals, especially where electricity usage is significant, changing company can make a measurable difference.

The key point is simple: You can only change company if you are the contract holder.

Final Thought

Many tenants assume they are stuck with whatever supplier the landlord chose. That is not always true. If you are paying the electricity, you should at least check whether the contract is in your name. If it is, you are legally entitled to change company and choose the tariff that suits your usage.
