The government has launched a national alert service and they are testing the system on Sunday 23rd April at 3pm. 

The alert will appear on mobile devices for 20 seconds and you will hear a loud, siren-like sound for up to 10 seconds, you can see and hear it here UK Emergency Alerts - YouTube

This may be frightening to residents who are vulnerable and unaware of the alerts. Can you please help ensure neighbours are made aware of the test, how to acknowledge it and if the alert will be particularly distressing how to opt out. For further information please visit the How emergency alerts work - GOV.UK (www.gov.uk) for instructions on how to opt out.
