How to Check Whether an Emergency Alert Is Real

A phone makes a loud sound, then a message appears telling people nearby to stay indoors. A few minutes later, someone forwards a screenshot that appears to say the opposite. It may be from a different area, an earlier incident or a different stage of the same event. You need to know what applies at your location and what action to take now.

There are two decisions. First, make yourself safe and follow any instructions from emergency services or a genuine alert on your device. Then check the source, time and area of other messages before acting on them or sending them on. If someone is in immediate danger, contact the emergency services without waiting to settle a dispute about a screenshot.

Recognise the UK Emergency Alerts service

GOV.UK describes Emergency Alerts as a service for life-threatening situations nearby, such as severe flooding or storms. A compatible device may sound a siren, vibrate and display a message even if it is set to silent. The message gives an instruction and may include a GOV.UK link or a number for more information. Alerts are based on where the device is at the time. The service does not need your phone number to send one.

Read the message and follow its instructions. If you are driving or riding, stop somewhere safe and legal before reading or responding. If you have questions about the message, open the government’s Emergency Alerts page independently and check its current or past alerts. Use other official sources where they apply to the incident, such as the relevant emergency service or local authority. A forwarded screenshot can be genuine and still be out of date or meant for somewhere else.

Check four details before forwarding a warning

1. Who issued it? Find the organisation named on the warning and open its official website or service independently. Check that the announcement can be found there or through another relevant official source.
2. When did it apply? Read the date, issue time and any stated end time. Look for a later update. A message can remain in a group chat after the advice has changed.
3. Where does it apply? Check the listed area, streets or map. A county-wide weather warning and a street-level evacuation instruction may both be accurate and apply to different people.
4. What action does it ask for? Look for the specific instruction, such as staying indoors, avoiding a route or going to a named place if safe. Pass on the source and time along with the instruction.

Separate the national alert from the other channels you already use. The Met Office publishes weather warnings. Flood authorities and local services publish warnings for their areas. A school, transport operator or building manager can issue instructions for their own premises or service. Check the right channel for the decision you need to make. A delayed train update and a local police cordon answer different questions.

Suppose a relative sends a picture of a severe flood warning. Read the affected area and when it was issued, then go to the official flood warning service for your location. A boundary may run along a particular watercourse or street. Follow the advice for where you are. If you are trying to help somebody elsewhere, confirm their actual location and direct them to the advice for that area.

Notice requests that do not belong in an alert

GOV.UK says the Emergency Alerts service will never email you or ask for personal details. Treat a message that asks you to log in, pay a charge or supply codes as suspicious. If it claims to come from a council or another organisation, find that organisation’s official website or number yourself. Use the contact listed there and check whether it has issued the request.

• A convincing name or logo. Search for the actual notice from the issuing organisation. A logo in an image tells you little about who posted it.
• An urgent link. Open the official service separately rather than using a link in an unverified email, post or text. Keep passwords and verification codes private.
• A cropped screenshot. Look for the date, affected location and full instructions. If a piece of information is missing, check the original before sharing it.
• A claimed test. Check current and past alerts and the issuer’s announcement. Read what the alert actually asks you to do, especially if other updates are circulating.

Keep the verification step proportionate. You do not need to search every channel for an instruction already confirmed by the relevant authority. Find out whether it is current, applies to your location and gives you a clear action. If the information is still uncertain, share that uncertainty explicitly and give people the route to the official source.

Keep track when the advice changes

An incident can generate an initial warning, a revised instruction and a later update for only part of the original area. Start with the latest full statement from the relevant authority. Read where it applies and whether it replaces earlier advice. A message published later by a different organisation may simply be describing another place or service. If a route closure is lifting and an evacuation instruction remains in place, follow the instruction for your location and check the incident authority before assuming it is safe to return.

Suppose your household chat still shows a screenshot that asks residents to stay indoors, followed by a neighbour’s message saying everything is back to normal. Open the incident authority’s latest notice and look for an explicit change. If you find one, give the group the time, the affected area and the instruction in one short message. Pin or mark the current update so a family member opening the chat later can identify it quickly.

If you discover that you forwarded an old notice, correct it in the same place. Say which message you are replacing and include the verified details or point people directly to the issuing authority. Consider contacting anyone who might already have left to act on the earlier advice. A correction reaches more people when it follows the same route as the original warning.

Make reliable updates available when phones fail

Not everyone in a household will receive the same alert. A device may be incompatible or have no connection, and somebody at work may be in a different area. Keep other ways to get information, such as radio, trusted local reporting and official updates through a contact who can reach you. Agree who will check on anyone who might need an accessible format, translation or help following instructions.

Save the relevant services now. Keep the official government alert page, weather warnings and local council or emergency service details where you can find them. If you have a battery radio, note a station you can tune to. Ask other people which source they would use without their phone. A little preparation reduces the chance that a crowded group chat becomes everyone’s only source of information.

Practise with a past alert on GOV.UK. Ask someone to identify its source, time, location and instruction without relying on the headline. Then ask how they would explain it to somebody who was in a different town. For a real warning, send only the relevant information, name the issuing authority and check for updates before repeating an older message. The test is whether the person receiving it knows what they need to do next.
