How Do EPC Ratings Work?

An Energy Performance Certificate (EPC) rating measures the energy efficiency of a property on a scale from A (most efficient) to G (least efficient). It provides buyers, tenants, and owners with insights into energy usage, carbon emissions, and potential savings.


šŸ“Š The EPC Rating Scale

RatingEfficiency LevelScore (SAP Points)
AExcellent92-100
BVery Good81-91
CGood69-80
DAverage55-68
EBelow Average39-54
FPoor21-38
GVery Poor1-20

🧮 How Is the EPC Rating Calculated?

A certified EPC assessor evaluates:

  • Insulation levels

  • Heating systems and controls

  • Window glazing type

  • Lighting (energy-efficient bulbs)

  • Building materials and age

  • Solar panels or renewable systems (if any)

They input the data into government-approved software to generate the SAP score, which translates into an A-G rating.


šŸ“„ What Else Does an EPC Include?

  • Estimated annual energy costs

  • Recommendations for improving energy efficiency

  • Current and potential ratings

  • COā‚‚ emissions data


šŸ› ļø Want to Improve Your Rating?

Simple upgrades like installing loft insulation, upgrading to double glazing, or switching to LED lighting can help move your property up a band.
