Drivers are being advised to exercise caution with the latest emergency call (eCall) technology fitted in most new cars and light commercial vehicles, following a warning from the Department for Transport (DfT).
The government has recently updated vehicular requirements to include the Next Generation (NG) eCall system. This advanced technology is mandatory for vehicles registered on or after 1 September 2025 - identified by “75” number plates. Conversely, vehicles with registration plates dated before this, such as those starting with “25” or earlier, are not required to have NG eCall fitted.
However, the DfT has highlighted that until 31 March 2027, NG eCall may not function reliably and should not be depended upon during emergencies. Vehicle owners uncertain about their car’s eCall capabilities are encouraged to consult their dealers for confirmation.

The Department explained that NG eCall has been implemented to standardise emergency calling systems across Europe. Upgrading the UK’s telecommunications infrastructure is necessary to support NG eCall compatibility, with completion anticipated by 31 March 2027.
The UK’s older 2G networks, which underpin the current eCall version, are due to be decommissioned in 2029 and 2030. NG eCall is engineered to operate on 4G and 5G networks, ensuring its functionality throughout most of a vehicle’s lifespan.
“NG eCall is designed to operate beyond the 2G network shutdown, providing consistent emergency connectivity for new vehicles across their lifetime,” said the Department for Transport.
eCall technology plays a crucial role in enhancing road safety by automatically alerting emergency services following serious collisions, enabling a swift response.
Until the telecommunications infrastructure upgrades are complete, the DfT advises that drivers should not rely solely on NG eCall in emergencies. Instead, contacting emergency services directly via mobile phone or roadside SOS phones remains essential.
The Department has committed to updating public guidance once NG eCall compatibility is fully established.
