National Emergency Alert test - Sunday 7 September 2025 at 3pm

Don't forget - the the National Emergency Alert test will be happening this weekend. The UK government is testing the system on Sunday 7 September 2025 at 3pm. Your mobile phone or tablet will vibrate and make a loud siren-like sound, even if it’s set on silent. The alert message will confirm this is a test and that you do not need to take any further action.
