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 31 May 2019
  • Non-Domestic EPCs: to 31 May 2019
  • Display Energy Certificates: to 31 May 2019

We have carefully considered the privacy risks to individuals in the disclosure of Energy Performance Certificate (EPC) data. The Ministry of Housing Communities and Local Government (MHCLG) has published a data privacy impact assessment (DPIA) to identify and minimise the data protection risk. This DPIA will be kept under review. Display Energy Certificate data relating to public authority buildings is not personal data in this regard.
