Yes, your EPC (Energy Performance Certificate) score can decline over time due to a variety of factors related to property condition, building regulations, and energy efficiency technology.
🔍 Why Does an EPC Score Decline?
Aging Systems & Insulation: Boilers, windows, and insulation become less efficient over time. If these aren’t upgraded, your property may score lower in a new EPC assessment.
Changes in EPC Standards: EPC calculation methods and regulations are updated periodically. What passed as a good score 10 years ago may not meet today’s expectations.
Renovations or Alterations: Certain changes to your home (like removing insulation or extending without energy-efficient features) can lower the rating.
Wear and Tear: Everyday usage and natural deterioration of heating systems, seals, or lighting systems can affect energy performance.
🔧 How to Prevent Your EPC Rating from Falling
Maintain and service your heating systems.
Upgrade to double or triple glazing.
Improve wall and loft insulation.
Switch to LED lighting.
Consider renewable energy installations like solar panels.
