These data are based on the number of new dwellings connected by the ESB to the electricity supply but exclude conversions. The classification used for "type of dwelling" up to 2004, is no longer available.
2005 is classified as follows:
"Individual House" is where connection is provided to separate detached house. "Scheme House" is where connection is provided to two or more houses. "Apartments" is where all customer metering for the block is centrally located.
