Energy Efficiency Certificate: What It Is and When It Is Mandatory in Spain

February 19, 2025

What is the Energy Certificate and Why is it Important?

The energy efficiency certificate is an official document that provides information about a property's energy consumption and CO2 emissions. Since 2013, it has been mandatory in Spain for selling or renting properties, becoming a key tool for owners, buyers, and tenants.

Its importance lies in several aspects:

It offers transparency about energy performance before buying or renting.
It allows the estimation of future energy costs.
It can increase the market value of the property.
It promotes energy efficiency in the real estate sector.
It prevents possible penalties for legal non-compliance.

The certificate uses a scale from A (most efficient) to G (least efficient), evaluating factors such as insulation, climate control systems, lighting, and orientation. In addition to the rating, it includes recommendations for improving efficiency.

In {{{"link": {"type": "category-pro", "category-pro": 5737}, "title": "Málaga"}}} and the Costa del Sol, where the climate significantly influences energy consumption, a favorable certificate can be especially attractive, translating into greater comfort and lower climate control costs.

In summary, the energy certificate is not only a legal requirement but also a valuable tool to promote sustainability and to help make more informed and environmentally responsible decisions in the real estate sector.

Obligation of the Energy Certificate in Spain

Now that we understand what the energy certificate is, it is crucial to know when it becomes mandatory. The energy efficiency certificate has been mandatory in Spain since 2013, according to Royal Decree 235/2013, updated by Royal Decree 390/2021. This regulation establishes its mandatory nature in the following situations:

Sale of buildings or parts of buildings
Rental of buildings or parts of buildings
Newly constructed buildings
Public buildings with more than 250 m² of useful area that are regularly frequented

However, there are some exceptions:

Buildings and monuments protected for their architectural or historical value
Buildings used as places of worship
Temporary constructions intended for use for less than two years
Industrial, defense, and agricultural buildings with low energy demand
Detached buildings with less than 50 m² of useful area
Buildings purchased for major renovations or demolition
Homes used for less than four months per year

In {{{"link": {"type": "category-pro", "category-pro": 5737}, "title": "Málaga"}}} and the Costa del Sol, with its dynamic real estate market, complying with this regulation is crucial. The lack of a certificate can lead to significant legal and financial consequences.

Penalties for non-compliance vary according to severity:

Mild infractions (not displaying the label): fines from 300 to 600 euros
Serious infractions (not registering the certificate): fines from 601 to 1,000 euros
Very serious infractions (falsifying information): fines from 1,001 to 6,000 euros

Besides avoiding penalties, having the certificate can offer competitive advantages in the local real estate market, especially for attracting buyers or tenants who value energy efficiency.

It is the owner's responsibility to obtain and renew the certificate, which is valid for 10 years (5 years for a G rating). After this period or if significant modifications are made, it will need to be renewed.

In conclusion, the obligation of the energy certificate in Spain not only fulfills a legal requirement but also offers the opportunity to improve energy efficiency and contribute to the sustainability of the real estate sector in Málaga and the Costa del Sol.

Process of Obtaining the Energy Efficiency Certificate

Once the obligation of the certificate is understood, it is essential to know the process to obtain it. The process to obtain the energy efficiency certificate involves several steps and requires the intervention of qualified professionals:

Hiring a certifying technician: The owner must hire a qualified professional such as an architect, technical architect, engineer, or technical engineer with specific training in energy efficiency.
Property visit and evaluation: The technician conducts a detailed inspection, analyzing:
- Construction features (walls, windows, insulation)
- Heating, cooling, and hot water systems
- Lighting
- Orientation and location of the property
Calculations and modeling: The technician uses specialized software to calculate energy demand and consumption.
Preparation of the report: A document is generated with the energy rating, a description of features, and recommendations for improvement.
Registration of the certificate: The technician registers the certificate with the competent authority of the Autonomous Community.
Delivery to the owner: The owner receives the certificate and the energy label for use in commercial activities related to the property.

According to current regulations, the technician must make at least one visit to the property no more than three months before issuing the certificate.

In Málaga and the Costa del Sol, where second homes and vacation rentals are abundant, it is crucial that owners are proactive in obtaining the certificate. The local climate, with hot summers and mild winters, may reveal significant opportunities for improvements in cooling systems and thermal insulation.

It is recommended that owners consider obtaining the certificate not only as a mandatory procedure but also as an opportunity to assess and improve the energy efficiency of their properties. This can translate into long-term savings and increase the property's appeal in a market that is increasingly conscious of sustainability.

Validity and Expiration of the Energy Certificate

After obtaining the certificate, it is essential to understand its period of validity and when it needs to be renewed. The energy efficiency certificate has a maximum validity of 10 years from its issuance. However, there are exceptions and important considerations:

G Rating: For properties with the lowest rating, the validity is reduced to 5 years.
Significant renovations: If modifications affecting energy efficiency are made, the certificate must be updated before its normal expiration.
Regulatory changes: Updates in legislation may require early renewal of certificates.

In Málaga and the Costa del Sol, specific factors may influence the need to update the certificate before its expiration:

The changing climate, with increasingly hot summers, may prompt improvements in cooling or insulation.
The dynamic local real estate market makes maintaining an updated certificate a competitive advantage.
Possible local incentives to improve energy efficiency could encourage renovations and certificate updates.

It is the owner's responsibility to keep the certificate valid and update it when necessary. Ignoring the expiration date or failing to renew it after significant modifications can result in penalties.

It is recommended that owners:

Note the expiration date of the certificate and set a reminder.
Keep a copy of the certificate in an accessible place.
Record any improvements that could affect energy efficiency.
Consult with a technician before making significant renovations.

Maintaining a valid and updated certificate not only complies with regulations but also demonstrates a commitment to energy efficiency and can increase the property's value in a market that is increasingly aware of sustainability.

Costs Associated with the Energy Efficiency Certificate

Now that we understand the importance and the process of obtaining the certificate, it is crucial to address the associated costs. The cost of the energy efficiency certificate can vary depending on several factors:

Size of the property: In Málaga, for a home of 50-100 m², the price typically ranges between 100 and 200 euros.
Type of property: Single-family homes generally have a higher cost than apartments.
Age and features: Older properties or those with complex systems may require a more detailed evaluation.
Location: In tourist areas like the Costa del Sol, prices may be slightly higher.
Qualification of the technician: Fees vary according to the professional's experience.

In addition to the certificate cost, one must consider:

Registration fees: In Andalusia, registration with the Junta costs around 30 euros.
Travel expenses: In remote areas, an additional charge may apply.
Updates: Renovations may require certificate updates.

Although it represents an expense, the energy certificate can be considered an investment. A good rating can increase the property's value and make it more attractive in the Costa del Sol market.

To optimize costs, owners can:

Request several quotes from accredited technicians.
Prepare the necessary documentation in advance.
Consider joint certification for multiple properties in the same building.
Take advantage of possible local campaigns or discounts.

In Málaga and the Costa del Sol, where second homes and vacation rentals abound, the energy certificate should be considered part of the property's operating expenses. Its cost can be quickly amortized if it facilitates the rental or sale of the property.

Penalties for Non-Compliance with Regulations

Understanding the costs of the certificate leads us to consider the financial consequences of not complying with the regulations. Penalties for failing to comply with energy certification regulations are classified into three categories:

Mild infractions (300 to 600 euros):
- Not displaying the energy label in advertisements
- Not renewing an expired certificate
- Failing to meet minimum content requirements
Serious infractions (601 to 1,000 euros):
- Not registering the certificate with the Junta de Andalucía
- Selling or renting without providing the certificate
Very serious infractions (1,001 to 6,000 euros):
- Falsifying information on the certificate
- Advertising a rating without a valid certificate

In Málaga and the Costa del Sol, it is important to consider:

The high turnover of properties can increase authorities' vigilance.
Many foreign owners may be unaware of Spanish regulations.
In a competitive market, non-compliance could be reported by competitors or interested parties.

To avoid penalties, owners should:

Obtain the certificate before starting sale or rental activities.
Include the energy label in all advertisements.
Keep track of the expiration date and renew on time.
Work with professionals who are up to date with regulations.
Consult with local authorities or legal advisors in case of doubt.

Complying with regulations not only avoids penalties but can also offer competitive advantages in the local real estate market, especially for attracting buyers or tenants who value energy efficiency.

How to Improve the Energy Efficiency of a Home

Beyond complying with regulations, improving the energy efficiency of a home in Málaga and the Costa del Sol can not only elevate the certificate rating but also generate significant savings and increase the property's value. Some effective strategies are:
