1. What Is EPC Rating?

EPC (Energy Performance Certificate) Rating is a standard assessment of a property's energy efficiency in the UK. It uses an A-G scale where A is the most efficient and G is the least efficient.

2. How Does The Calculator Work?

The calculator uses custom standards-based algorithms to estimate EPC rating based on:

Where:

• Energy Efficiency Score - Base energy performance points
• Property Type - Detached, semi-detached, terraced, or flat
• Construction Year - Age of the property
• Insulation Level - Quality of insulation (Excellent, Good, Average, Poor)

Explanation: The calculation considers multiple factors that affect a property's energy performance, applying adjustment factors based on UK energy efficiency standards.

3. Importance Of EPC Rating

Details: EPC ratings are legally required for property sales and rentals in the UK. They help homeowners understand energy costs, identify improvement opportunities, and can affect property value.

4. Using The Calculator

Tips: Enter accurate information about your property. The energy efficiency score should be based on professional assessment where possible. All values must be valid and within reasonable ranges.
