The domestic and non-domestic Energy Performance of Buildings Registers (the registers) are 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 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 registers and not the data published on this website.
Data included in this site
- Domestic EPCs: to 1st October 2016
- Non-Domestic EPCs: to 1st October 2016
- Display Energy Certificates: to 31st Dec 2017
We are carefully considering the privacy risks to individuals in the disclosure of Energy Performance Certificate (EPC) data. At this stage we cannot provide a date for the next EPC data publication. Display Energy Certificate data relating to public authority buildings is not personal data so we have decided to publish an update to this data.
