EPC C is not just about one measure. The current score, property type, heating, insulation, solar potential, evidence and recommendation sequence all affect the practical route.
The current EPC shows the rating, score, potential score, assumptions and recommendations. The first step is to find the EPC, then assess the gap to Band C.
- •Current rating and SAP score
- •Potential EPC score where available
- •Existing recommendation descriptions
- •Assumed inputs or missing evidence
The best route to EPC C is not always the longest list of measures. Heating, hot water, insulation, controls, solar PV, lighting and glazing should be considered together.
- •Heating and controls
- •Wall, roof and floor insulation
- •Solar PV suitability
- •Hot water and lighting
Improvement works can only be reflected in an EPC where allowed by current RdSAP methodology and supported by suitable evidence.
- •Invoices and installer details
- •Product specifications and model numbers
- •Photos before and after works
- •Certificates, U-values and completion documents
