For residential charging, property owners require enough space to park an EV within the boundaries of their property such that a charge cable can be connected without crossing a public right of way.
Field Dynamics have created a robust dataset to determine households that do (or do not), have enough space to park and charge within the boundaries of their property. Using Ordnance Survey’s OS MasterMap Topography and AddressBase datasets, Field Dynamics have identified the properties and adjacent land parcels for all 28+ million households in Great Britain. Each property has been assessed using Field Dynamics advanced algorithms to provide the parking propensity score of 0, 1 or 2 for each individual UPRN. Segments adjacent to a road are considered as parkable and if one or more of these segments is within a property’s boundary, that property will be given an off-street flag (i.e. 1 or 2).
We have supported the technical analysis with over 1000 field surveys to validate and improve our modelling. However, whilst the analysis identifies households that have parkable space, we are unable to determine how that space is used or whether local bylaws would enable the space to be used for parking.
We then use recent Zapmap data (31.03.2024) to identify the locations of all charge points and focused on charging locations as opposed to devices or connectors, as different devices and sites can provide different numbers of connectors at any one time. Once all chargepoint locations have been loaded, Field Dynamics determined how far someone could walk in five minutes in each direction from the charge point. These journey end points are joined together to create a polygon called an isochrone. If an on-street household falls within one of these isochrones, we consider it to be covered by the charger
