Emergency alerts issued to around 500,000 people in Isles of Scilly and Cornwall

The Cabinet Office issued two emergency alerts to approximately 500,000 people across the Isles of Scilly and Cornwall on Thursday 8 January¹. The alerts are recorded in the UK Government Resilience Action Plan: 2026 Implementation Report, published by the Cabinet Office and updated on 1 October 2026¹.

The same report records that storms Chandra, Goretti and Ingrid "caused severe disruptions and widespread utility failures in January 2026"¹. It does not state in the quoted passage what the two alerts of 8 January were issued for, and no further detail on their content or the areas covered within Cornwall and the Isles of Scilly has been reported¹.

The report sets the alerts in the context of a wider year of incidents. It records a RED heat weather warning in June 2026, with temperatures reaching a maximum of 37.3C in Suffolk, and COBR standing up a Severe Weather Resilience Network in response to periods of heat in June, July and August¹. It also records a Meningitis B outbreak in Kent requiring a coordinated public health response, including immunisation and antibiotic distribution sessions and a one-off vaccination campaign, and the MV Hondius Hantavirus outbreak in May 2026, which required the safe evacuation of over 20 British nationals back to the UK¹. Separately, it refers to the Manchester Synagogue Attack in October 2025¹.

Why it matters for households

Emergency alerts are sent to compatible mobile phones in a defined area and produce a loud sound and on-screen message even when the phone is on silent¹. The report gives the number of people reached but does not describe the action householders were asked to take, so what recipients were told has not been reported¹. Households in Cornwall and the Isles of Scilly who received the alerts, or who want to know how the system works, can read the guide to Emergency Alerts: How the UK Phone Warning System Works, check whether a handset is compatible in Will Your Phone Receive Emergency Alerts?, and find out about location data and cost in Do Emergency Alerts Track Your Location or Cost Anything?. The settings can be changed using the guide on how to turn emergency alerts off or on. The report also notes that the government is designing a national resilience public engagement campaign anchored in GOV.UK/Prepare, launching later in the year¹.

What happens next

The report says an updated National Risk Register was published alongside it to reflect the latest developments in the risk landscape¹. It also records that a public call for views has been launched to gather evidence from the resilience community ahead of the review of the Civil Contingencies Act 2004¹. A review into the response to Storm Goretti has been launched, the report says¹.
