An Energy Performance Certificate (EPC) itself does not issue a “pass” or “fail” — rather, it assigns a rating from A (most efficient) to G (least efficient) based on the property’s energy use and CO₂ emissions. However, a low EPC rating (E or below) can be considered a “fail” for certain purposes, especially for landlords and commercial property owners.
Key Reasons a Property May “Fail” an EPC Requirement:
Poor Insulation
Properties without sufficient loft, wall, or floor insulation tend to score very low. Missing or outdated insulation significantly reduces energy efficiency.Inefficient Heating Systems
Outdated or non-condensing boilers, old electric storage heaters, or lack of central heating will lead to a poor EPC score.Single-Glazed Windows
If the property still has single glazing or poor-quality windows, it negatively impacts thermal performance.Lack of Low-Energy Lighting
The absence of LED or other low-energy lighting fixtures can contribute to a lower rating.Uninsulated Hot Water Cylinder
Not having an insulated hot water tank can lead to energy waste and reduce the EPC score.
When Does a Low EPC Score Matter?
For landlords, renting out a property with an EPC rating lower than E is illegal unless the property qualifies for an exemption under EPC regulations. Failing to meet the minimum standard can result in fines and legal action.
If your property receives a low rating, you can take steps to improve it before a reassessment. Our Same-Day EPC Service helps you act quickly, and our certified assessors offer guidance to help raise your rating efficiently.
