Navigating the property market, whether as a buyer, seller, or landlord, involves a multitude of considerations. One such crucial factor is the Energy Performance Certificate (EPC), a comprehensive evaluation of a building’s energy efficiency. An EPC provides a rating from A (most efficient) to G (least efficient), which directly impacts a property’s attractiveness and value. It also offers potential occupants a glimpse into their future energy bills.

A property’s energy performance, which is an essential aspect of a home’s energy performance, emerges from an assessment of multiple factors such as:

  • the type of construction
  • the type of dwelling
  • boilers
  • insulation
  • renewable energy installations

This assessment results in an energy rating that quantifies the energy efficiency of the building, offering a clear indication of the property’s energy performance.

Improving a property’s EPC rating can significantly boost its value, potentially by as much as 20%. This is due to the perceived energy efficiency of the property and the prospect of reduced future energy expenses. In other words, a higher EPC rating means better home’s energy performance and potentially lower energy costs for the occupant.

The ABCs of EPCs

An Energy Performance Certificate (EPC) is a formal report that provides valuable insights into a property’s energy consumption, efficiency, and potential expenses. An energy certificate, such as display energy certificates and energy certificates, is a legal requirement in the following situations:

  • When selling or leasing a property
  • Upon completion of a new building
  • When modifications are made to its heating, air conditioning, or mechanical ventilation systems.

EPCs, through their energy efficiency rating, allow for a comparison of energy performance between different properties and encourage the implementation of energy improvements.

The Life Span of an EPC

Valid for a decade, an EPC gives a snapshot of how energy efficient a property is during this period. Over this period, the EPC offers a reliable reflection of the property’s energy performance and potential energy costs. However, any significant changes to the property that might affect its energy efficiency require a new EPC assessment.

This ensures that the information on the EPC remains current and accurate, thereby allowing potential buyers or tenants to make well-informed decisions.

EPCs and Property Value

The value and market appeal of a property can be significantly influenced by its EPC rating. Properties with a higher EPC rating (A or B) usually command sale prices at least 14% higher than those with lower ratings. This is because energy-efficient homes are not only more comfortable and environmentally friendly but also result in lower energy bills for the occupant.

Therefore, improving the EPC rating of a property can be a smart investment, potentially increasing a home’s value by up to 20%.
