    EPC Registers

    EPC Registers

    • A complex suite of services to manage and analyse information relating to the energy efficiency of buildings
    • Delivery to tight schedule within a dynamic political and statutory landscape
    • Successful long-term operation of a complex end-to-end process involving over 12,000 stakeholders


    The European Energy Performance Certificate of Buildings legislation mandate that Energy Performance Certificates for domestic and non-domestic buildings be stored in a secure fashion for up to 15 years and to be accessible by authorised personnel, including the general public and mortgage lenders.                                   

    Landmark’s operation of the Registers fulfils this requirement.

    • Designed to handle in excess of 4M lodgements per year, and around 10 million XML message transactions annually. Data to be stored for a period of 15 years
    • Fourteen year contracts on behalf of The Ministry of Housing, Communities & Local Government (MHCLG) and Department of Finance Northern Ireland to enable them to fulfil their obligations under the European Energy Performance of Buildings Directive (EPBD)

    Our Solution

    System has been in operation since 2006. Operated as concession contracts, Landmark underwriting the design, build and deployment of the system. Revenue returned on operational fees based on the lodgement of individual reports

    Deployed on dedicated IT infrastructure to operate and deliver the Registers to stringent service, security and business continuity conditions

    Unit lodgements based on complex site/property address and building function criteria. Landmark operates a sophisticated address matching service to assist Energy Inspectors with the lodgement process.

    A key element of this project is the secure exchange of information between the various bodies involved in the process. These may include:

    • Energy Assessors and Surveyors involved in the EPC/HCR survey process
    • The numerous Certification and Accreditation bodies who certify the Inspectors and Assessors
    • Communities and Local Government
    • Landmark, as operator of the Registers

    The information is exchanged between these organisations as a series of secure XML messages, which have been defined by CLG and Landmark, and which are published as a set of XML XSD schemas.

    These include messages for:

    • Defining the report structure
    • Lodging, updating and retrieving reports to and from the Registers
    • Various mechanisms for maintaining a Register of Inspectors

    Landmark has implemented mechanisms to send and receive XML messages as

    • Encrypted HTTPS/XML Socket Services
    • SOAP XML Web Services

    Implicit in this service is the creation and parsing of XML/XSD into other data formats and into database tables.

    Landmark has worked closely with the stakeholder community to assist them in their operational responsibilities through the provision of guidance, support, documentation, on-line test harnesses and application interface tools
