Energy Performance Certificates#

Last modified: 10 Dec 2024

Introduction#

An Energy Performance Certificate (EPC) provides information on the energy efficiency of a building providing detailed (from most efficient band A to least efficient band G) including average energy efficiency ratings, energy use, carbon dioxide emissions, fuel costs, average floor area sizes and numbers of certificates recorded. Available since 2008, an EPC is required when a building is constructed, sold or let and it is valid for 10 years. This dataset provides the EPCs including 52 variables on the characteristics of domestic properties in England and Wales.

TRANSACTION TYPE

Type of transaction that triggered EPC. For example, one of: marketed sale; non-marketed sale; new-dwelling; rental; not sale or rental; assessment for Green Deal; following Green Deal; FIT application; none of the above; RHI application; ECO assessment. Where the reason for the assessment is unknown by the energy assessor the transaction type will be recorded as ‘none of the above’. Transaction types may be changed over time.

Environmental

ENVIRONMENT IMPACT CURRENT

The Environmental Impact Rating. A measure of the property’s current impact on the environment in terms of carbon dioxide (CO₂) emissions. The higher the rating the lower the CO₂ emissions. (CO₂ emissions in tonnes / year).
