When an EPC (Energy Performance Certificate) is issued for your property, it evaluates multiple aspects of your building’s energy efficiency. These assessments are carried out by an accredited EPC assessor and help you understand how your home or commercial building performs in terms of energy usage and environmental impact.
✅ Key Elements Evaluated in an EPC Assessment
Building Fabric & Insulation
Wall insulation (cavity or solid wall)
Loft/roof insulation
Floor insulation
Windows (single, double, or triple glazing)
Heating Systems
Type and efficiency of your main heating system (e.g., gas boiler, heat pump)
Secondary heating (like electric heaters or fireplaces)
Heating controls (thermostats, timers, TRVs)
Hot Water System
Water heater type (combi boiler, cylinder, immersion heater)
Insulation of hot water tanks and pipes
Lighting
Percentage of energy-efficient lighting (LED, CFL, etc.)
Use of automatic lighting controls
Ventilation and Air Leakage
Natural vs mechanical ventilation
Air tightness and draught-proofing
Renewable Energy Systems
Solar panels (PV or thermal)
Wind turbines
Ground or air source heat pumps
Property Dimensions and Layout
Total floor area
Room height
Orientation (impacting solar gain)
🎯 EPC Rating Outcome
After reviewing these factors, your property is rated from A (most efficient) to G (least efficient) and issued a SAP rating (E-number).
This report also includes recommendations for improvements to raise your score and lower running costs.
📌 Why This Matters
Understanding these evaluation points can help:
Landlords comply with minimum energy standards (MEES)
Homeowners plan upgrades before selling
Buyers & tenants compare running costs of properties
