GoodiHow is the EPC score calculated?
The score (1–100) is the property's energy efficiency rating, produced by an accredited Domestic Energy Assessor using the UK Government's Standard Assessment Procedure (SAP). A higher score means a more energy-efficient home that's cheaper to run.
It's calculated from the property's physical characteristics, including:
- Size & floor area
- Construction & age
- Wall, roof & floor insulation
- Windows / glazing
- Main heating & controls
- Hot water & lighting
These are the factors shown in the certificates above. The score maps to a band — A (92–100, most efficient) down to G(1–20). The "potential" score is what could be achieved with the recommended improvements. Source: MHCLG EPC Register.
