Here’s an explanation of EPC ratings and their implications:

A: ‘A’ rated properties are the best of energy efficiency, resulting in considerably lower energy bills. These properties typically have excellent insulation and energy-efficient heating systems.

B: Properties rated ‘B’ are also highly efficient, with good insulation and energy-saving features that make them economical to maintain.

C: A ‘C’ rating indicates compliance with the minimum energy efficiency standards set by building regulations, denoting average efficiency.

D: Properties with a ‘D’ rating have moderate energy efficiency and may need upgrades to lower energy use. Most homes in England and Wales are in this category, despite being less efficient than ‘A’, ‘B’, or ‘C’ rated homes.

E: ‘E’ rated properties are inefficient and incur higher energy costs, but they can be improved with energy-saving modifications.

F: An ‘F’ rating reflects poor efficiency, leading to high energy expenses. Major enhancements are required for a better rating.

G: ‘G’ rated properties are the least efficient, with the highest energy expenses, necessitating extensive energy-saving interventions for improvement.
