Can an EPC Rating Go Down Over Time? What You Should Know

If you’ve previously received a strong EPC rating, it’s natural to wonder whether it can change. The short answer is yes—EPC ratings can decline over time, and understanding why can help you stay compliant and energy-efficient.

🔍 Why Do EPC Ratings Drop?

1. Regulatory Updates
   EPC standards are updated regularly. What was considered a ‘C’ rating five years ago might not meet the same standard today.

2. Property Changes
   Renovations that reduce insulation, remove efficient heating systems, or change the layout may impact your rating negatively.

3. Deterioration of Systems
   Over time, boilers, insulation, and windows degrade, leading to reduced efficiency if not maintained or upgraded.

4. Improved Assessment Techniques
   As EPC assessments become more accurate with updated software and criteria, older certificates might not reflect true performance anymore.

✅ How to Prevent a Drop in EPC Rating

• Regular Maintenance of insulation, heating systems, and windows.
