What is an EPC rating?
An Energy Performance Certificate (EPC) measures how energy efficient a property is, giving it a rating from A (most efficient) to G (least efficient).
The certificate also includes estimated energy costs and recommendations that could improve the property's efficiency.

Do EPC ratings affect mortgage approvals?
In most cases, EPC ratings do not directly determine whether a mortgage is approved. Lenders mainly focus on factors such as income, credit history, property value and affordability.
However, EPC ratings are becoming more relevant in the mortgage process as lenders increasingly consider energy efficiency when assessing long-term property value.
Green mortgages and EPC ratings
Some lenders now offer green mortgages which provide incentives for buying energy-efficient homes or improving a property's EPC rating.
These incentives may include:
- Lower mortgage interest rates
- Cashback offers
- Additional borrowing for energy improvements
Properties with higher EPC ratings (typically A–C) are more likely to qualify for these types of mortgage products.
Do low EPC ratings affect property value?
While an EPC rating alone does not determine property value, lower ratings can sometimes influence buyer decisions.
Properties with poor energy efficiency may require upgrades such as insulation or heating improvements, which buyers may factor into their offers.
As energy costs remain a key concern for homeowners, many buyers are paying closer attention to EPC ratings during the purchase process.
Can you improve your EPC rating before selling?
Yes. Many homeowners make improvements before selling their property to achieve a better EPC rating.
Common improvements include:
- Installing loft insulation
- Upgrading heating systems
- Installing double glazing
- Using energy-efficient lighting
- Adding heating controls
Even small upgrades can help improve a property's energy efficiency score.
What happens during an EPC assessment?
An accredited energy assessor will inspect several aspects of the property, including:
- Wall construction
- Loft insulation
- Heating systems and controls
- Windows and glazing
- Hot water systems
- Lighting efficiency
Most EPC assessments take around 30–60 minutes, depending on the size and layout of the property.
