Energy performance certificate (EPC) data
Energy performance certificates rate building efficiency across Europe, and their data drives retrofit, lending and ESG decisions. This guide covers EPC data.
Available across the EU. DataSupplier sources and delivers this data in all 27 European Union countries — including Germany, France, Spain, Italy, the Netherlands and Poland — and across the EEA, in the format and cadence you need.
Why EPC data matters now
Building decarbonisation, minimum-efficiency rules and green finance all rely on energy ratings. EPC data provides a standardised, building-level view of efficiency at scale.
The data landscape
- Ratings: energy-efficiency bands.
- Attributes: building characteristics and measures.
- Recommendations: improvement potential.
- Coverage: registers by country.
Common use cases
Retrofit and decarbonisation planning, green lending and mortgage analysis, portfolio and ESG reporting, and market analysis.
Reliability considerations
EPC methodologies and quality vary by country and assessor, and ratings can be dated. Understanding methodology and freshness is essential, and matching EPCs to properties needs address resolution.
Sourcing considerations
National EPC registers vary in openness and access. Personal data can appear, and provenance matters for lending and ESG use.
In a managed model
A managed partner can source EPC data across registers, matched to properties and documented.
Methodology and freshness vary
EPCs give a standardised, building-level efficiency view, but methodologies and quality vary by country and assessor, and ratings can be dated. Understanding method and freshness, and matching EPCs to properties via address resolution, is essential before relying on them.
Coverage and privacy
National EPC registers vary in openness and access, personal data can appear, and provenance matters for retrofit, green-lending and ESG use.
