Interception

What is interception?

Interception means the interception of communication in the course of its transmission via a postal service or telecommunications system (such as a telephone or computer) so as to make it available to a third party.

The law permits interception of communications by law enforcement and intelligence agencies in tightly controlled circumstances.

Interception can only be authorised:

  • in the interests of national security
  • preventing or detecting serious crime
  • safeguarding the economic well-being of the UK.

Roughly 2,000 intercept warrants are authorised a year (Source: the Interception of Communications Commissioner's report for 2007). Read theĀ Interception code of practice
