Threat levels

There are 5 levels of threat:

• low - an attack is highly unlikely

• moderate - an attack is possible but not likely

• substantial - an attack is likely

• severe - an attack is highly likely

• critical - an attack is highly likely in the near future

The level is set by the Joint Terrorism Analysis Centre and the Security Service (MI5).

Threat levels do not have an expiry date. They can change at any time as different information becomes available to security agents.

 In July 2019 changes were made to the terrorism threat level system, to reflect the threat posed by all forms of terrorism, irrespective of ideology. There is now a single national threat level describing the threat to the UK, which includes Islamist, Northern Ireland, left-wing and right-wing terrorism
