Across Stockport and the wider SK postcode area, many properties share similar designs, ages and layouts. However, when an Energy Performance Certificate (EPC) is carried out, these homes can often receive very different ratings.
This can come as a surprise to homeowners, especially when neighbouring properties appear almost identical.
Different Heating Systems
One of the biggest factors affecting EPC ratings is the heating system. Even within the same street, properties may have boilers installed at very different times.
A newer, more efficient system will typically result in a higher EPC score compared to an older one.
Insulation Levels
Insulation is another key factor. Some properties may have upgraded loft insulation or wall insulation, while others have not.
These differences are not always visible but can significantly impact the final EPC rating.
Improvements Made Over Time
Over the years, homeowners make various upgrades — new windows, heating controls, or extensions. These improvements can gradually increase a property’s energy efficiency.
If these upgrades are documented and visible, they will be reflected in the EPC assessment.
Evidence Available During the Assessment
EPC assessors rely on evidence. If improvements cannot be verified, standard assumptions must be used.
This can sometimes result in a lower rating, even if upgrades have been made.
Why This Matters in Stockport
Stockport is a competitive property market where buyers often compare similar homes. EPC ratings can influence perception, particularly when energy costs are a concern.
This trend is also visible in nearby markets such as Reading and regional areas like Preston.
