What is an EPC (Energy Performance Certificate)?
An EPC is a legal document that displays a building’s energy efficiency, required for properties being sold or rented in the UK. The rating ranges from A (most efficient) to G (least efficient).
What Does an EPC Include?
Heating, cooling, and lighting performance
Estimated energy usage
Environmental impact
Recommendations for efficiency improvements
Why Does an EPC Matter?
✅ Raises Awareness: Encourages homeowners to improve energy efficiency.
🧠 Informs Decisions: Helps buyers and renters compare properties.
💰 Reduces Costs: Implementation of EPC advice can lower your energy bills.
EPC Calculation Factors
🏠 Building Type & Size
🧱 Insulation Quality
🔥 Heating System Efficiency
💡 Lighting Type
🌬️ Ventilation System
☀️ Renewable Energy Sources (e.g., solar panels)
📍 Location & Exposure (wind/sun)
How is an EPC Calculated?
1. Standard Assessment Procedure (SAP)
The UK government uses SAP, a regulated methodology to assess:
Wall, floor, and roof construction
Windows and insulation
Boiler and heating systems
Hot water systems
Energy-efficient lighting
Renewable installations (e.g., solar, wind)
2. Data Collection
An accredited energy assessor collects property data via:
Visual inspections
On-site measurements
Questionnaires
Reviewing existing documents (e.g., plans, certifications)
3. Calculation & Rating
The data is entered into approved EPC software, which calculates:
EPC rating (A–G)
Energy Efficiency Indicator (EEI)
Recommended improvements

Types of Energy Assessments
Existing Domestic Buildings:
Performed by Domestic Energy Assessors (DEAs) for houses, flats, and bungalows. Results are processed via government-approved software.
Non-Domestic/Commercial Buildings:
Handled by Non-Domestic Energy Assessors (NDEAs). Required for shops, offices, and industrial units. Complex buildings may need higher-level NDEA qualifications.
New Domestic Buildings:
Assessed by On-Construction Domestic Energy Assessors (OCDEAs) using construction plans and post-build inspections.
Public Buildings:
Display Energy Certificate (DEC) Assessors evaluate libraries, town halls, and other frequently visited public buildings.
