The most significant factors that lower an Energy Performance Certificate (EPC) rating—and how to address them effectively on a limited budget—include:
🔻 Top Factors That Lower an EPC Rating:
Poor Insulation
Cause: Inadequate roof, wall, or floor insulation.
Impact: Major heat loss and higher energy bills.
Low-Budget Fix:
Install or upgrade loft insulation (relatively inexpensive and high impact).
Use thermal curtains or DIY insulation kits for windows and doors.
Inefficient Heating Systems
Cause: Old boilers or lack of thermostatic controls.
Impact: Wastes energy, raises heating costs.
Low-Budget Fix:
Fit thermostatic radiator valves (TRVs).
Upgrade to a programmable thermostat.
Single Glazed or Draughty Windows
Cause: Outdated windows with air leaks.
Impact: Significant heat loss.
Low-Budget Fix:
Use secondary glazing film.
Apply draught excluders or sealant tape.
Poor Lighting Efficiency
Cause: Use of incandescent or halogen bulbs.
Impact: Adds unnecessary energy usage.
Low-Budget Fix:
Switch to LED lighting throughout the property.
Lack of Renewable Energy Features
Cause: No solar panels or energy recovery systems.
Impact: Lowers potential EPC score.
Low-Budget Fix:
While solar PV panels are costly, smart energy usage (e.g., off-peak consumption) and battery-powered solar chargers can make a small impact.
