UK Threat Levels

The UK Threat Levels are the alert states that have been in use since 1 August 2006 by the British government to warn of forms of terrorist activity. Before then a colour-based alert scheme known as BIKINI state was used.[1] The response indicates how government departments and agencies and their staffs should react to each threat level.

Current threat level

The threat level is currently Severe, which was upgraded from Substantial on 29 August 2014.[2]

Categories of threat

Since 24 September 2010, the Home Office has reported three different categories of terrorist threat:[3][4]

The Joint Terrorism Analysis Centre (JTAC) is responsible for setting the threat level from international terrorism and the Security Service (MI5) is responsible for setting both threat levels related to Northern Ireland.[5]

Threat levels

Severe An attack is highly likely.
HEIGHTENED

Substantial An attack is a strong possibility.
Moderate An attack is possible, but not likely.
