Improving your property only to find a lower EPC (Energy Performance Certificate) rating can be frustrating and confusing. But what causes this issue, and what can you do about it?
Why EPC Ratings May Drop After Improvements
There are a few reasons an EPC rating might decrease even after renovations:
Incorrect Installation: Energy-saving improvements like insulation or double glazing must be installed to professional standards. Poor workmanship may reduce effectiveness.
Changes to the Building Fabric: Extensions or alterations without compensatory energy upgrades can impact the overall rating.
Different Assessor Criteria: EPCs are issued by accredited assessors. A different assessor may use slightly different assumptions or spot previously undocumented inefficiencies.
Outdated Recommendations: Sometimes, work is completed based on outdated EPC recommendations. If newer technologies have emerged, your changes might not offer the best gains.
