Contacts and Complaints - Security Service MI5
The MI5 Phoneline
for providing
information to the Service
Since March 1998 a public telephone number
– the MI5 Phoneline: 020 7 930 9000 – has
been available for those wishing to provide
information to the Service to assist it in its
work. Members of the public may for instance
become aware of activities which they think
may be relevant to the Service’s functions:
others may be personally involved with groups
investigated by the Service, or closely
associated with them, and may have
information to offer via the Phoneline. As an
alternative to the Phoneline, information may
be sent in writing to the Service’s Enquiries
Desk (details below). Any information provided,
and the identities of callers, will be treated
with the greatest care.
The MI5 Phoneline should not be used for
enquiries about the Service, including
employment opportunities, which should be
sent instead to the Enquiries Desk. In addition,
it should not be used for reporting information
about imminent threats to life or property,
which should be passed to the police using the
999 system, or via the Anti-Terrorist Hotline –
0800 789321 – which is for giving the police
information about a terrorist incident which has
happened or is about to occur.
