Energy Performance Certificates (EPCs) are a legal requirement for all properties being sold or rented in Portugal. These certificates assess a building’s energy efficiency on a scale from A+ (most efficient) to F (least efficient), helping buyers and tenants understand the property’s energy consumption and potential costs. The EPC must be included in all real estate listings and is issued by a certified technician after an on-site evaluation.

Beyond compliance, having a high EPC rating can increase a property's value and marketability. Energy-efficient homes are more attractive to eco-conscious buyers and renters, and they benefit from lower utility bills. In Portugal’s growing real estate market, improving your home’s energy performance not only supports sustainability but also enhances investment appeal.
