Counting Public Chargers

The Office for Zero Emission Vehicles' methodology

In February 2026, OZEV decided to count chargers as opposed to charging devices, which it had previously counted.

A charger is defined by OZEV and Zapmap to be "an independent part of a charging device which controls the charge session, enabling one EV to charge at a time".

On our local authority pages, we are presenting the NEVIS Near Home charging metric. This metric is designed to measure public charging provision for those who use public chargers because they cannot access home chargers.

OZEV's charger statistics, which are obtained in partnership with Zapmap, include the raw number of chargers in each local authority, and the raw number of 50kW+ chargers in each local authority. We do not present these on our local authority pages because power and spatial distribution are important to those who use public chargers because they cannot access home chargers. We are working on statistics using chargepoint data under the Open Data requirement of the Public Charge Point Regulations 2023.

We are presenting charging devices to give a sense of the scale of government-funded public chargepoint schemes, including in the On-Street Residential Charging Scheme tabs on our local authority pages. OZEV used this charging devices metric in its grant scheme statistics.
