Benefits of an Energy Assessment
💷 Save Money: Identify ways to reduce your energy bills—many households save hundreds of pounds annually.
🔥 Boost Comfort: Eliminate cold spots and enjoy consistently warm, well-heated rooms.
🌍 Reduce Carbon Footprint: Lower your home’s emissions by using less energy.
💡 Access ECO4 Grants: Qualify for government funding for recommended improvements.
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.
FAQ
In the UK, special people called energy assessors check how well your home uses energy. They look at all sorts of things, like the type of house you have, how big it is, and how old it is. They also check how much energy you use to heat and light your home.
Energy assessors use a special system called SAM to check your home. SAM looks at all the factors that affect how much energy your home needs. These include the type of walls, windows, and doors you have, and whether you have any renewable energy sources like solar panels or wind turbines.
Once the energy assessor has checked your home, they will give you an EPC certificate. This certificate tells you how efficient your home is at using energy. It also gives you tips on how to make your home more energy efficient.
Your EPC rating is valid for ten years. This means that you don’t need to get a new one unless you make major changes to your home, like changing the type of heating system you have.
