When buying a house in Portugal, understanding the energy certification system is essential. This document isn’t just a formality—it plays a crucial role in every real estate transaction. Whether you’re purchasing, selling, or renting a property, the energy certificate is mandatory and provides a detailed overview of the building’s energy efficiency. Let’s break down what international investors need to know.
What is Energy Certification?
The energy certificate evaluates a property’s energy performance, rated from A+ (most efficient) to F (least efficient). It reveals insights into energy consumption, environmental impact, and potential savings.
Since 2008, the certificate has been required for all new constructions (Decree-Law 78/2006 and Ordinance 461/2007), and since 2013, for all properties listed for sale or rental (Decree-Law 118/2013).
Only certified professionals accredited by ADENE (Portuguese Energy Agency) are authorized to issue it. They assess elements like insulation, heating and cooling systems, hot water production, and solar exposure.
