With Great Power Comes Great Responsibility: Use of UK Emergency Alert System

Sarah Schubert

The nationwide wildfire emergency alert issued across England and Wales on 14 August raises an important question for the UK’s resilience community: what is an emergency alert actually for?

This is not an argument that the wildfire risk was insignificant. Conditions were exceptionally challenging, major incidents were occurring and fire and rescue services were under considerable pressure. The Government described the wildfire risk as “very high” and the consequences of recent fires, including the destruction of homes in Stourbridge, demonstrated how serious that risk could become.

The question is instead whether the emergency alerts system was the most appropriate means of communicating general preventative safety information to an entire population when, for most recipients, there was no imminent emergency requiring immediate protective action.

An emergency system is for emergencies

The Government’s own description of Emergency alerts is clear: it is a system providing warning and advice during a life-threatening emergency[1]. Recipients are told that, when an alert arrives, they should “stop what you’re doing” and follow the instructions. Phones produce a distinctive, loud siren-like noise, even when set to silent, and vibrate for around ten seconds.

That intrusiveness is not an unfortunate side effect. It is one of the system’s greatest strengths. During development of the system research undertaken by the University of Hull with the Environment Agency, Cabinet Office, EE, and Fujitsu[2] found that the distinctive and intrusive nature of cell broadcast alerts encouraged people to pay attention and consider taking protective action. The technology was deliberately designed to cut through the huge amount of information people receive every day.

This created something valuable: an exceptionally high-salience communication channel. We should therefore be extremely cautious about spending that value. The alert sent on 14 August told people across England and Wales that there was a very high wildfire risk and advised them not to undertake activities that might start a fire, including using disposable barbecues, firepits, garden incinerators or fireworks. People were also asked to call 999 if they saw a fire.

All of that is sensible public safety advice. But it is fundamentally different from directive advice in an emergency for those whose lives are in danger: there is a wildfire approaching your community; leave now, severe flooding is expected in your area; move to higher ground, or there is an immediate threat to life; shelter indoors.

For much of the population receiving the alert, sometimes more than once, there was no specific incident nearby and no immediate protective action required. The communication objective was principally risk reduction and prevention. Whilst important information it is not emergency information.

The dangers of normalising the alarm

The effectiveness of any warning system ultimately depends on human behaviour. When that unmistakable alarm sounds, we need people to think: Something serious is happening. I need to look at this now. We should be concerned if repeated use gradually changes that response to: This is probably another piece of general advice. I will look at it later.

The warning literature describes the potential for over-warning to contribute to warning fatigue, scepticism and reduced trust. Research in the bushfire context has specifically identified over-warning, credibility, false alarms and scepticism as interconnected factors affecting warning response[3]. The evidence around a simple “cry wolf” effect is more nuanced than is sometimes suggested, but the underlying principle remains important: authorities need to preserve public confidence that an intrusive warning signifies something requiring attention rather than creating warning fatigue.

However, there is an even more tangible risk. People can, and do, simply turn emergency alerts off. Government guidance[4] explains how users can disable both “severe” and “extreme” alerts. If people begin to regard the system as another channel for general government messaging, some inevitably may decide that the interruption is not worth it. The consequence might not become apparent until the day an alert really does concern an immediate threat to their life.

Public warning capability is therefore not simply a technological asset. Public trust and attention are finite resources that need to be protected.

The safeguarding issue cannot be forgotten

There is another important consideration. From the earliest national tests, concerns were raised about people experiencing domestic abuse who keep concealed mobile phones[5]. Because an emergency alert can override silent settings and produce a loud alarm, it can reveal the existence of a hidden device to an abuser.

The Government explicitly recognises this risk. Its current guidance states that victims of domestic abuse with a concealed phone may consider turning Emergency alerts off. Ahead of previous planned national tests, government and public bodies actively publicised this issue so that people potentially at risk could take appropriate precautions.

This creates an uncomfortable policy trade-off. Someone experiencing domestic abuse may have to choose between keeping emergency alerts enabled so that they receive potentially life-saving warnings, or disabling them because an unexpected alarm could reveal a concealed phone. That risk may be justifiable where there is an imminent threat to life. Emergency warning inevitably involves balancing competing risks. It becomes much harder to justify when the alert is being used to distribute preventative information that could reasonably have been communicated through less intrusive channels.

The Government's announcement of the 14 August alert discusses the wildfire threat and the advice being provided, but does not address this safeguarding consideration. Given how prominently the issue featured during testing, it should remain part of the decision-making process every time the system is activated.

Other ways to communicate

None of this means the Government should have remained silent. Quite the opposite. Fire and rescue services needed the public to understand the exceptional conditions and change their behaviour. A coordinated national communications campaign would have been entirely appropriate.

The Government itself makes clear that emergency alerts sit alongside local news, radio, television and social media rather than replacing them. Websites, broadcast media, social media, news notifications, national and local government channels, fire and rescue service communications, transport messaging, signage at high-risk locations, retailer engagement and targeted communication to visitors in vulnerable areas were all available. Indeed, much of this activity was already taking place.

Emergency alerts should have remained available for what they are uniquely good at: rapidly reaching people within an affected geographical area when there is a time-critical threat and immediate action is required. Cell broadcast technology is particularly suited to precisely this type of geographical targeting. People receive alerts according to where they currently are, rather than where they live. A national prevention campaign and a targeted emergency warning are complementary tools. They should not become interchangeable.

A legitimate question about decision-making

There is also a governance question that deserves examination. The timing of the alert was politically conspicuous. Earlier on 14 August, the Prime Minister visited Stourbridge following the devastating wildfire there. The Government's own press release presented the emergency alert alongside that visit, emergency funding, military assistance and the temporary ban on disposable barbecues as part of a wider package of government action. The alert then began being distributed from approximately 19:00.

That does not establish that the decision to use the emergency alert system was politically motivated, and it would be wrong to claim that without evidence. It does, however, make transparency particularly important.

Was the alert initiated because emergency professionals assessed that the established threshold for national emergency warning had been reached? Who requested its use? What criteria were considered? What alternatives were examined? What assessment was made of proportionality, geographical targeting and safeguarding? And was the decision entirely operational, or did the desire to demonstrate visible national action following the Prime Minister's visit influence the choice of communications channel? Those are legitimate resilience and governance questions, not party-political ones.

An emergency warning system must never become or even be perceived as becoming a mechanism through which government demonstrates that it is “doing something”. Its credibility depends upon a clear separation between emergency communication and political communication.

Protect the exceptional

The wildfire conditions of August 2026 provide an opportunity to review how the Emergency alerts system should be governed as its use becomes more familiar.

A sensible principle would be to reserve the most intrusive form of alert for circumstances involving a credible threat to life where rapid communication and timely protective action are required. That should be supported by:

• clear and published activation thresholds;

• proportionality between the threat, geographical area and population alerted;

• an expectation that the message contains meaningful and time-critical protective action;

• explicit consideration of vulnerable groups, including people with concealed phones;

• consideration of less intrusive communication channels before activation; and

• routine post-incident evaluation of public understanding, behaviour, trust and opt-out rates.

  
  

The UK has invested in a powerful public warning capability. We should not judge its success by how often it is used. We should judge it by whether, when the alarm sounds, people immediately understand that it matters and take action.

The wildfire advice issued on 14 August was important. The conditions were serious. The intention to prevent further fires and reduce pressure on emergency responders was understandable. But that does not remove the need to ask whether an emergency alert was the right instrument.

Some communication channels derive their power from being exceptional. The safest way to preserve that power is to keep them exceptional.
