The Currrent UK Threat Level is :

SEVERE

What are threat levels?

A new system has been created to keep the public informed about the level of threat to the UK from terrorism.

The system also helps the police and other law enforcement agencies determine how they should respond to, and prepare for a terrorist incident. 

The threat levels are:

• critical - an attack is expected imminently 
• severe - an attack is highly likely
• substantial - an attack is a strong possibility
• moderate - an attack is possible but not likely
• low - an attack is unlikely

Who decides the threat levels?

The Security Service (MI5) and the Joint Terrorism Analysis Centre work together to decide the level of threat to the UK. More information about how the threat levels are decided (new window) is available on the Security Service website.
