If you own or live in a flat above a commercial premises, such as a shop or café, you might face unique challenges when it comes to Energy Performance Certificate (EPC) assessments. These mixed-use properties often confuse EPC software algorithms, leading to unexpected low ratings. Here’s why EPC assessors often struggle with flats above shops—and how it could affect your property’s compliance.
The Complexities of Mixed-Use Buildings in EPC Assessments
Flats above shops present a tricky scenario because they combine domestic living spaces with commercial environments. EPC assessors must isolate and evaluate the residential portion, but several factors complicate this:
Uninsulated Commercial Roof Spaces: If the shop below has an uninsulated flat roof, it directly affects the thermal performance of the flat above.
Shared Heating Systems: Some properties have heating systems that serve both the shop and the residential unit, making accurate efficiency calculations challenging.
Limited Access to Inspection Areas: Assessors may not have access to ceilings, roofs, or service areas of the commercial premises, forcing them to apply default (often poor) values.
Mixed Construction Types: Older buildings with shopfront extensions can create inconsistent wall and floor insulation scenarios.
Why Flats Above Shops Often Receive Poor EPC Scores
Even if the flat itself is well-maintained, EPC software penalises properties when:
There’s insufficient insulation data for adjoining commercial structures.
Shared services (like heating and ventilation) lack clear energy usage separation.
The shop below has large glazed shopfronts affecting thermal performance assumptions.
These factors can cause a 1 to 2 band drop in EPC rating, impacting landlords’ ability to let the property under Minimum Energy Efficiency Standards (MEES).
How to Improve EPC Ratings for Flats Above Shops
Document All Insulation and Upgrades: Ensure all energy-saving measures in the flat (and if possible, the shop below) are documented for the assessor.
Separate Heating Controls: Install independent heating controls or systems for the flat.
Roof and Floor Insulation Improvements: Focus on insulating floors above commercial spaces and shared ceiling voids.
