At 3pm on Sunday 7 September 2025, the UK Government will carry out its second nationwide test of the Emergency Alerts system, sending a test message to mobile phones across the country.
As part of the alert, mobile phones will vibrate and make a siren-like noise, even if the phone is set on silent.
Clive Grunshaw, Police and Crime Commissioner for Lancashire, said:
“We understand that some victims of domestic abuse in Lancashire may have a hidden phone or tablet for their safety. With the UK Government’s Emergency Alerts test taking place on 7 September, we’re urging anyone in this situation to either opt out of the alerts or ensure their device is switched off.
“Testing the Emergency Alert system is important, but so is protecting domestic abuse victims whose hidden devices could be exposed, putting their safety at risk. That is why it is so important that we make every effort to ensure that people in vulnerable situations are aware of the upcoming test.
“Preventing violence and women and girls is a top priority in my Police and Crime Plan, and as Police and Crime Commissioner I will continue to work alongside Lancashire Constabulary to prevent these crimes, as well as fund services to support victims.”
