Security Industry AuthorityGovernment

The Security Industry Authority (SIA) is an executive non-departmental public body sponsored by the UK Home Office. Its mandate is to regulate the UK's private security industry by compulsory licensing of individual security operatives and managing the voluntary Approved Contractor Scheme. Established in 2003 under the Private Security Industry Act 2001, it issued its first licenses in 2004 to help curb criminality and raise professional standards across the sector.
