What is a critical aspect of energy performance certificates (EPCs)?

Energy Performance Certificates (EPCs) are essential documents designed to provide information about the energy efficiency of a building. A critical aspect of EPCs is that they must be displayed publicly for properties that are being sold or rented out. This requirement ensures that potential buyers and tenants are informed about the energy performance of the building, which not only influences their decision but also promotes awareness and accountability regarding energy consumption and efficiency.

Public display of EPCs also aligns with broader regulatory and environmental goals, encouraging property owners to improve their buildings' energy efficiency. By making this information readily accessible, it fosters transparency within the real estate market and supports consumers in making informed choices based on energy performance ratings.

In contrast, aspects such as whether they are optional for landlords, their validity for only a year, or evaluating tenant behavior do not accurately reflect the primary objectives and legal stipulations associated with EPCs. Thus, the requirement for public display stands out as a key characteristic of energy performance certificates.
