Energy performance certificate (EPC)

What is an Energy Performance Certificate (EPC)?

An Energy Performance Certificate (EPC) is a document that assesses and rates the energy efficiency of a building or property. It provides information about energy use and performance, along with recommendations for improving efficiency.

In simple terms, EPC refers to a standardised assessment that shows how efficiently a property uses energy.

Importance of an Energy Performance Certificate

An EPC helps property owners, buyers, tenants, and businesses understand a building’s energy performance and identify opportunities to improve efficiency. It can support decisions around energy-saving upgrades, reduce energy consumption and operating costs, and contribute to broader sustainability goals.

Uses of an Energy Performance Certificate

An EPC is used to:

Assess the energy efficiency of residential and commercial properties

• Identify potential energy-saving improvements
• Support informed property-related decisions
• Evaluate a building’s energy performance and environmental impact
• Plan upgrades such as improved insulation, efficient lighting, HVAC systems, or renewable energy solutions
• Support applicable energy efficiency and sustainability requirements

Examples of an Energy Performance Certificate

An EPC may be used by a homeowner assessing a property’s energy efficiency before making upgrades, a buyer or tenant comparing properties, or a commercial building owner planning energy-saving improvements. It may also support property developers and facility managers in evaluating and improving the energy performance of their buildings.
