This page aims to present data on electric vehicle (EV) charging for home, workplace, public (ONS/ZapMap and National Chargepoint Registry), and combined charging sockets/devices/connections.
+ ++ To present an idea of the full picture we combine the number of home, workplace, public charging sockets/devices/connections (see notes below).
+ -This map shows where the Office for Zero Emission Vehicles (OZEV) has provided grants (EVHS, DRS, and EVCG) for domestic charging devices. These figures will not include home charging devices that have been installed without a grant.

- For our total value, we add the number of workplace, home, and public-access charging points for each lower-tier 2022 local authority district. - Homecharging and publicly available "devices" represent charging devices at all speeds. A device can have a number of connectors of varying speeds. - We count each of these "devices" as one unit as there is no way to know how many individual sockets they have. - Workplace statistics are for the number of "Sockets Installed", which we also count as one unit. -
-- For public charging points we are not using most recent July 2023 data because they have changed the geographic boundaries. - For homecharging we are using 2022 data. At some point this will update with a 2023 value and we will need to see if they also use updated geographies. - Workplace charging uses April 2023 data. -
-The Electric Vehicle Charging Device Statistics (ONS/ZapMap) references 44,020 devices (July 2023). According to ZapMap "there were 48,450 electric vehicle charging points across the UK, across 29,062 charging locations" as of the end of August 2023. As of early September 2023, the National Chargepoint Registry contains 49,343 In service connections from 31,589 devices. So the NCR's connections appear to be comparable to ZapMap's devices. The NCR data include latitudes/longitudes for each device and that makes it possible to aggregate by constituency easily.
In our previous analysis (April 2022) we identified at least 50 chargepoints that had been given incorrect coordinates by their operators; some had their latitudes/longitudes swapped around, some had the wrong sign on the longitude, and some had duplicated the latitude in the longitude value. In the current dataset it hasn't been possible to associate 134 locations (149 connections) with constituencies.
+For each source we have had to use different concepts of "connections".
