What is a Domestic EPC Used For?
A Domestic Energy Performance Certificate (EPC) is an essential document that provides a comprehensive assessment of your property's energy efficiency. Here's what it covers:
Primary Purposes
- Property transactions: Required when selling or renting a home
- Energy efficiency assessment: Rates properties from A (most efficient) to G (least efficient)
- Improvement guidance: Provides recommendations for enhancing energy efficiency
- Cost savings: Helps identify ways to reduce energy bills
- Environmental impact: Shows carbon dioxide emissions and environmental footprint
- Compliance: Meets legal requirements for property transactions
When is a Domestic EPC Needed?
Legal Requirements
- Selling a property: Must have a valid EPC before marketing
- Renting a property: Required for new tenancies
- Building new homes: New builds must have EPCs
- Converting properties: When changing property use
- Renovating: Major renovations may require new assessments
Validity Period
- EPCs are valid for 10 years
- Must be renewed if expired before selling/renting
How is a Domestic EPC Formulated?
Assessment Process
- Qualified assessor visit: A certified Domestic Energy Assessor (DEA) conducts an on-site survey
- Property inspection: Assessor examines:
- Building construction and materials
- Heating systems and controls
- Hot water systems
- Lighting systems
- Insulation levels
- Windows and glazing
- Ventilation systems
- Data input: Information is entered into government-approved software (RdSAP - Reduced Data Standard Assessment Procedure)
- Calculation: Software calculates:
- Energy efficiency rating (A-G scale)
- Environmental impact rating (CO2 emissions)
- Estimated energy costs
- Potential improvement recommendations
- Report generation: Creates the official EPC document with:
- Current efficiency rating
- Potential rating after improvements
- Specific improvement measures
- Estimated costs and savings
- Environmental impact data

Technical Details
RdSAP Methodology
The Reduced Data Standard Assessment Procedure (RdSAP) is the government-approved software used to calculate EPC ratings. It uses standardized assumptions and data to ensure consistency across assessments.
Data Accuracy & Limitations
- Visual assessment: Assessors can only inspect what's visible and accessible
- Standardized assumptions: Some data uses industry standard values
- What EPCs don't cover: Actual energy consumption, comfort levels, or detailed thermal modeling
- Professional standards: All assessors must be qualified DEAs with appropriate accreditation
