A Simple Guide For
Understanding UK Threat Levels
In the UK, we have a system to measure the risk of terrorism, known as “threat levels.” This system helps people understand how likely a terrorist attack could happen and helps the government and security services take the right actions to keep us all safe.
The threat level system was created to give the public and organisations a clear idea of the current security situation. It’s designed to be easy to understand, with five different levels. Let’s break down each one.
The 5 Threat Levels
- Low
This means that an attack is highly unlikely. It’s the lowest level and indicates that there’s no known plan or current risk of terrorism. Even in this case, security measures remain in place just in case something unexpected happens. - Moderate
At this level, an attack is possible but not likely. The government may still be monitoring certain groups or individuals, but there is no immediate threat to public safety. - Substantial
A substantial threat level means an attack is likely to occur. This is a more serious warning, and the government steps up protective measures. People are often reminded to stay vigilant, report anything suspicious, and follow security advice. - Severe
When the threat level reaches “severe,” it means an attack is highly likely. The public is advised to be extra cautious, and security is heightened across the country, especially in high-profile locations like airports, train stations, and public events. - Critical
The highest threat level, “critical,” means an attack is expected very soon, possibly within hours or days. This is a rare level, but when it happens, the government may implement emergency measures, such as deploying more police and security forces in public areas.

How Are Threat Levels Set?
Why Should We Care About Threat Levels?
The threat levels are set by the Joint Terrorism Analysis Centre (JTAC) and the Security Service (MI5). These organizations constantly review intelligence (information from various sources) about potential terrorist threats. They look at several factors, such as the activities of known terrorist groups, recent attacks, and changes in global political situations.
For example, if intelligence suggests that a certain group is planning an attack, or if there has been an increase in suspicious activity, the threat level may be raised.
You can read more about JTAC and MI5’s role in setting threat levels on MI5’s official website.
It’s important to understand threat levels so we can be aware of the risks and take any necessary precautions. While these levels don’t tell us exactly when or where an attack might happen, they help us understand the general security environment.
For businesses, schools, and organizations, knowing the threat level can help them decide whether to implement extra safety measures, like increasing security checks or monitoring access to buildings.
For the general public, threat levels remind us to stay alert and report anything unusual to the authorities. If you see something that doesn’t seem right, like a suspicious package or someone acting strangely, it’s always better to speak up. You can find advice on reporting suspicious activity on Action Counters Terrorism (ACT), the UK’s official counter-terrorism campaign.
How You Can Stay Safe
Even though the government and security services are working hard to protect us, there are simple steps everyone can take to stay safe:
- Be aware of your surroundings, especially in crowded places.
- Trust your instincts. If something feels off, report it.
- Follow any security advice when visiting public places or attending large events.
- Stay informed by keeping up with the news and any changes to the threat level.
In summary, UK threat levels give us a clearer understanding of the current risk of terrorism. By staying informed and alert, we can all do our part to keep each other safe. For ongoing updates, check the UK Government’s threat level page.
