Energy Performance Certificate Now Mandatory Before Property Appraisal: What You Need to Know

On August 12, 2025, a new regulation came into force that changes the rules in the real estate sector: from now on, it is mandatory to have a valid Energy Performance Certificate (EPC) in order to carry out a mortgage appraisal of a property.

This means that if you are planning to buy with a mortgage, sell, or refinance your property, you must ensure you have this document updated. Both the appraiser and the bank will verify that the certificate is properly registered and valid.

Why is the energy certificate mandatory for appraisals?

With the publication of Order ECM/599/2025, dated June 10, which amends Order ECO/805/2003 on property valuation standards, the EPC is now a key requirement in the appraisal process.

The regulation aims to bring more transparency and reliability to valuations by incorporating energy efficiency as a determining factor in the property’s value.

Since August 12:

• If you don’t have the certificate, or if it is expired, the appraiser cannot issue the appraisal report.
• The certificate must be registered and no older than three months in the cadastral or property register.

Notary Jaime Calvo Francia advises checking this requirement even before signing the deposit contract, to avoid delays or transaction blocks.

Differences depending on the property’s status

The regulation makes a distinction between two scenarios:

• Completed buildings: the registered energy certificate must be submitted.
• Buildings under construction or in project phase: the certificate and a copy of the registration request must be provided, with consistent data.

Reminder: It has been mandatory since 2013 for sales

The energy certificate is not new: since June 2013 it has been required when selling a property (unless the buyer waives it). The novelty is that now the document must be available before the appraisal, adding an essential step to any mortgage transaction.

What is the energy certificate and what does it measure?

The Energy Performance Certificate (EPC) shows the amount of energy a property consumes under normal conditions and its level of efficiency. It classifies properties on a scale from A (most efficient) to G (least efficient).

Additionally, the report provides recommendations for improvements that can increase property value and reduce energy costs.

Who can issue an energy certificate?

Traditionally, only architects and engineers qualified under the Building Management Law (LOE) could issue them. However, Royal Decree 659/2025 expands eligibility:

• For new buildings, it will remain the responsibility of architects and engineers.
• For completed or existing buildings, other professionals with accredited training may issue certificates, including those with university degrees, vocational training, or professional certifications, once they register a declaration of responsibility with their regional authority.
