Security Industry Authority
The Security Industry Authority (SIA) is the organisation responsible for regulating the private security industry. We are an independent body reporting to the Home Secretary, under the terms of the Private Security Industry Act 2001. Our mission is to regulate the private security industry effectively to reduce criminality, raise standards and recognise quality service. Our remit covers the United Kingdom.
We have two main duties. One is the compulsory licensing of individuals undertaking designated activities within the private security industry; the other is to manage the voluntary Approved Contractor Scheme, which measures private security suppliers against independently assessed criteria.
Castlegate Security Services Ltd holds SIA approved contractor status for the provision of Security Guarding services.
