Energy Performance Certificates (EPCs) are mandatory in Portugal for all properties being sold or rented. These certificates provide a rating of a building’s energy efficiency on a scale from A+ (most efficient) to F (least efficient), helping buyers and tenants make informed decisions about energy costs and environmental impact. Issued by certified professionals, an EPC includes recommendations for improving energy performance, such as upgrading insulation or installing energy-efficient heating systems.

The EPC is valid for 10 years and must be presented during property transactions. It has become increasingly important in Portugal’s real estate market, especially as demand grows for sustainable and energy-efficient homes. In addition to helping reduce utility bills, a better EPC rating can also increase a property’s value and attractiveness to potential buyers or renters.
