Are Buildings Built Before 1951 Exempt from Energy Certification?

There is a lot of confusion surrounding the obligation of energy certification for old buildings, especially those built before 1951. Contrary to what some think, there is no automatic exemption from energy certification for these buildings. The current legislation, established by Decree-Law No. 101-D/2020, applies to all properties under certain conditions.

In this article, we clarify the rules and exceptions, so you know exactly what to do in the case of your property.

What Does the Current Legislation Say?

According to Decree-Law No. 101-D/2020, the energy certificate is mandatory in situations such as:

1. Sale of Properties – It is mandatory to present a valid energy certificate before advertising or completing the sale of a property.
2. Rental – Certification is also required for properties placed on the rental market.
3. Significant Renovation Works – Whenever interventions alter the structure or energy performance of the building.

And What About Buildings Built Before 1951?

Buildings constructed before 1951 are not automatically exempt from energy certification, even if they are old. The obligation of certification depends on the following:

• Real Estate Transactions: If the property is put up for sale or rent, the certificate is mandatory regardless of its construction date.
• Significant Alterations: If the property undergoes works that change its structure or energy performance, the certificate must be updated.

⚠️ Important Note: Even if the property retains original features like stone or wood constructions, these do not exempt the energy certificate if it is legally required.

Are There Any Exceptions?

Yes, the legislation foresees some specific exceptions, but these are not directly related to the property’s age. For example:

• Buildings classified as historical or cultural heritage may be exempt but must have documentation proving this classification.
• Properties that are not used for permanent residential purposes, such as warehouses or industrial buildings, may be exempt in some cases.

To confirm the need for certification, it is advisable to consult a specialized technician.

How to Obtain the Energy Certificate?

If you need an energy certificate for a property built before 1951, the process is simple:

1. Contact a Qualified Expert – Only certified technicians can issue energy certificates.
2. Schedule an Evaluation – The expert will inspect the property and determine its energy rating.
3. Receive the Certificate – After evaluation, the certificate will be issued and registered in the Energy Certification System (SCE).

If you have doubts about the need for an energy certificate, it is always recommended to consult a specialized technician or contact a certified company like Engenatura.
