These statistics have been published by the Department for Transport on a monthly basis since December 2021. This document sets out information on the data sources and methodology used to produce them.
Quality
These statistics are badged as Experimental Statistics. Users should be aware of the status and cautions of these series, which will vary for each statistic and will be explained within each publication. The statistics are new but still subject to testing in terms of their volatility and ability to meet customer needs. They do not meet the rigorous quality standards of National Statistics, for example with respect to partial coverage. Further details on the limitations of Experimental Statistics can be found on the Office for National Statistics guidance page.
Data source
Charging device location data is sourced from the electric vehicle charging platform Zap-Map and represents a snapshot of publicly accessible devices across the UK reported as operational at midnight as at the first of each month. Data from Zap-Map is sourced from Charge Point Operators and registered users of the site, who have added their own charging device.
Coverage
Zap-Map report that they cover 95% of publicly accessible devices across the UK however there is no way of assessing whether data coverage is better in some geographical areas than others. These data do not cover privately owned domestic or workplace devices that are not accessible to the public meaning the true number of electric charging devices across the UK will be higher.
