The Department does not hold data on Green Deal Advice Reports or Green Deal Finance Plans. DCLG is responsible for the data that produce Energy Performance Certificates, Display Energy Certificates and Air Conditioning Inspection Reports (ACIRs). This data are stored on the Energy Performance of Buildings Registers and are managed on DCLG's behalf by Landmark Information Group. The Registers currently contain data related to over 11 million energy certificates.
In 2012 the Energy Performance of Buildings (Certificates and Inspections) (England and Wales) Regulations 2007 were amended to make some of the data contained in the above documents publicly available. The data are available in bulk to authorised recipients (set out in regulations, and including Green Deal relevant persons) who have a need to process and analyse the data for purposes also set out in regulations. Authorised recipients are charged for the cost of supplying the data, and the disclosure of data to them is subject to conditions intended to protect certain types of information, including personal data. This data can be made available to promote energy efficiency improvements pursuant to a Green Deal plan and to determine whether these improvements have been made.
The Department for Energy and Climate Change has a separate contract with Landmark Information Group to operate the Green Deal Register (i.e. separate to the contract that DCLG has with Landmark to operate the Energy Performance of Buildings Registers). The Green Deal Register contains lodgement data for Green Deal Advice Reports (and Green Deal Improvement Packages) as well as the data supporting Green Deal Finance Plans.
