Introduction A monthly updated snapshot of the number of meters connected by local authority district and Lower Layer Super Output Area (LSOA) and by meter category: smart (smart and advanced); and not smart (analogue). Specifically, our smart meter definition is: Profile Class 0-4 meters only; and Meters in Measurement Class A,F and G only.Note 1: where UK Power Networks borders NGED and SSEN, and share coverage of common local authorities, only UK Power Networks customers connected to the UK Power Networks are shown.Note 2: the smart meters are mapped to LSOA using Office for National Statistics datasets which are updated annually. However, UK Power Networks smart meter installation counts are updated monthly so there is a natural but negligible discrepancy.Contains Local Authority district code and name and LSOA (lower layer super  output area) code and name sourced from the Office for National Statistics (ONS) licensed under the Open Government Licence v.3.0 Methodological Approach Data Extraction and Cleaning: Smart Meter installation data is extracted by postcode, such that each post code has a count for smart meters; analogue; and advanced. Aggregation: Each post code is assigned to an LSOA and local authority using ONS data. Polygon Creation: Each LSOA is then assigned to a polygon. Quality Control Statement Quality Control Measures include: Data only shown with confirmed postcode to LSOA mapping Manual review and correction of data inconsistencies Assurance Statement The Open Data Team and Income Management Team worked together to ensure data accuracy and consistency.
