This dataset consists of downloadable files in Comma Separated Values (CSV) format, for Display Energy Certificate data for public buildings and Energy Performance Certificate data for non-domestic buildings with energy certificates in England and Wales.
The Energy Performance of Buildings Register (the register) is the official place for all Energy Performance Certificates (EPCs), Display Energy Certificates (DECs) and Air Conditioning Inspection Reports (ACIRs).
The open data published on this website has been made available for data analysis to enable independent research into energy efficiency issues such as fuel poverty and climate change. The department has chosen only to publish data from 1 October 2008. The open data should not be relied upon to check if a valid EPC has been produced on sale or rent of a building, if a DEC has been produced for a public authority building over a certain size or if an ACIR has been produced for an air conditioning system.
To check for compliance with all regulatory and legal requirements the definitive source of EPCs, DECs and ACIRs is the register and not the data published on this website.
The frequency of publications has changed, Energy Performance Certificates are now updated monthly.
