An Energy Performance Certificate (EPC) provides a detailed assessment of a building’s energy efficiency and environmental impact. During the evaluation, a certified assessor will inspect a range of features that affect the building’s energy usage. Here’s what’s typically reviewed:
🔍 Key Components Evaluated in an EPC
Building Construction
Type of walls, floors, and roofing materials
Presence of insulation and its thickness
Thermal efficiency of materials used
Heating Systems
Type of central heating (e.g. gas, electric, oil)
Boiler age and efficiency
Radiators and controls (thermostats, TRVs)
Hot Water System
Cylinder insulation
Type of water heating and controls
Secondary water heating sources
Windows and Glazing
Double or single glazing
Frame materials and thermal performance
Lighting
Number of energy-efficient bulbs
Type and efficiency of lighting installed
Ventilation and Air Tightness
Natural or mechanical ventilation
Draught-proofing and air leakage levels
Renewable Technologies
Solar panels (PV and thermal)
Heat pumps, biomass, or wind energy systems
📊 Final EPC Rating
Once all components are assessed, your property is given:
An Energy Efficiency Rating (from A–G, where A is most efficient)
An Environmental Impact Rating, reflecting CO₂ emissions
