New Energy Certificate Rules in Spain: What Homeowners Need to Know in 2026

 

Energy Performance Certificates (EPCs) have become an essential part of Spain's real estate market. From 23 July 2026, important regulatory changes come into effect, strengthening the certification process and providing greater protection for homeowners, buyers, landlords, and tenants.

If you are planning to sell, rent, renovate, or invest in property in Spain, these new rules may affect you.

 

What Has Changed?

 

The update to Royal Decree 390/2021 is designed to improve transparency, enhance the reliability of Energy Performance Certificates, and provide greater confidence in the certification process.

One of the most significant changes is the creation of a Central Register of Qualified Energy Assessors.

This official register will allow property owners to verify that the professional issuing their Energy Performance Certificate is fully qualified and legally authorised.

The objective is to reduce fraud, improve professional standards, and increase public confidence in the certification system.

 

Greater Protection for Property Owners and Buyers

 

Until now, Spain had no unified public database where homeowners could easily verify the credentials of energy certification professionals.

The new register aims to professionalise the sector by ensuring that certificates are prepared by qualified experts with the appropriate technical knowledge.

This benefits both property owners and prospective buyers by increasing the reliability of a document that plays an increasingly important role in real estate transactions.

 

Energy Certificates Are Now More Important Than Ever

 

Although Energy Performance Certificates remain legally required when selling or renting a property, their role has expanded considerably.

Today, they are also essential for:

 

• Applying for government renovation grants.
• Accessing energy-efficiency subsidies.
• Qualifying for certain tax deductions.
• Demonstrating the property's energy performance during sales transactions.

 

As sustainability becomes a central focus of the housing market, obtaining an accurate and professionally prepared certificate is increasingly valuable.

 

Energy Efficiency Will Shape the Future of Spanish Real Estate

 

Energy efficiency is becoming one of the key drivers of property values across Europe.

Spain is expected to gradually implement the European Energy Performance of Buildings Directive (EPBD), which aims to transform the country's housing stock by improving building efficiency, reducing energy consumption, and increasing the use of renewable energy.

Properties with higher energy ratings are expected to become increasingly attractive to buyers and investors alike.

 

How Long Is an Energy Certificate Valid?

 

Most Energy Performance Certificates remain valid for ten years.

 

However, properties that receive the lowest energy rating (Grade G) are only valid for five years, meaning owners will need to renew their certificates more frequently.

 

New Energy Ratings May Be Introduced

 

The European Union is currently considering new classifications to recognise the most energy-efficient buildings.

Future ratings such as "Plus" and "Zero" could identify properties with exceptionally low energy consumption or nearly zero emissions.

Although these categories have not yet been officially introduced, they reflect the direction in which the European property market is evolving.

 

How Can You Improve Your Property's Energy Rating?

 

Improving a property's energy efficiency can increase both its market value and its long-term appeal.

Some of the most effective improvements include:

 

• Installing External Thermal Insulation Systems (ETICS).
• Replacing old windows with high-performance glazing.
• Improving roof insulation.
• Upgrading heating and cooling systems.
• Installing renewable energy systems such as solar panels.

 

These upgrades reduce energy consumption while making homes more attractive to future buyers and tenants.

 

Final Thoughts

 

The new Energy Performance Certificate regulations represent another important step towards a more transparent, sustainable, and professional Spanish property market.

Beyond being a legal requirement for selling or renting a home, Energy Performance Certificates are becoming increasingly important for accessing financial incentives, improving property value, and meeting future environmental standards.
