What Happens During an EPC Assessment?

An Energy Assessor will visit your property to gather the information needed to produce an accurate Energy Performance Certificate (EPC). The assessment is straightforward and typically involves collecting details about your home's construction, heating systems, insulation, and overall energy efficiency.

Property Information

During the visit, the assessor will record key details about your property, including:

  • Age and construction type
  • Wall, roof, and floor insulation
  • Heating and hot water systems
  • Heating controls
  • Lighting and other energy-related features

This information is used to calculate your property's energy performance.

Photographs

The assessor will take photographs throughout the inspection to support the information recorded in the EPC. These images are required as evidence and may include features such as insulation, heating equipment, meters, or other energy-related elements. They may also photograph relevant documentation, such as certificates or records of energy efficiency improvements carried out at the property.

Floor Plan

A floor plan will be created showing the layout and approximate dimensions of the property. It will also identify rooms and include information used to calculate heat loss, such as party walls and external walls.
