What is SIA Licence (Security Industry Authority)?

An SIA licence is mandatory for any individual providing licensable private security services in the UK, including door supervision, CCTV operation, close protection (bodyguarding), vehicle immobilisation, key holding and cash and valuables in transit. Licences are issued by the Security Industry Authority (SIA), a non-departmental public body under the Private Security Industry Act 2001. Applicants must pass an SIA-approved qualification, satisfy identity, criminal record and right-to-work requirements, and pay the licence fee (£190 for a three-year licence from 2024). Working without a valid licence is a criminal offence; businesses using unlicensed operatives are also liable.
