Why choose an NSI Approved Company?

The National Security Inspectorate is the leading approvals and certification body that inspects companies providing home security, business security and fire safety Services. Choosing an NSI approved company ensures that the contractor you select works to the highest recognised industry standards as demanded by the Police, Fire and Rescue Services and insurance industry.


NSI award several different levels of accreditation - dependant on what levels the inspected company is working to.

The highest level awarded is a gold award - which Kings Armoured Security Services Ltd has achieved.


All NSI approved companies:

•  Meet all relevant British and European Standards for technical performance

•  Security screen all relevant staff (security companies)

•  Provide a high level of staff training and supervision to industry best practice standards

•  Are comprehensively insured to protect Customers and staff

•  Are inspected every six months by professional auditors including random site visits


NSI Gold companies also:

•  Meet the industry specific ISO 9001:2015 Quality Management System Standard

•  Demonstrate a long term track record of performance and evidence of reliability and stability

The Security Industry Authority is the organisation responsible for regulating the private security industry. They are an independent body reporting to the Home Secretary, under the terms of the Private Security Industry Act 2001.


Their mission is to regulate the private security industry effectively; to reduce criminality, raise standards and recognise quality Service. Their remit covers the United Kingdom.


The SIA 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.


The SIA licensing covers manned guarding (including security guarding, door supervision, close protection, cash and valuables in transit, and public space surveillance using CCTV), key holding and vehicle immobilising. Licensing ensures that private security operatives are 'fit and proper' persons who are properly trained and qualified to do their job.


The SIA Approved Contractor Scheme introduced a set of operational and performance standards for suppliers of private security Services. Those organisations that meet these standards are awarded Approved Contractor status. This accreditation provides purchasers of private security Services with independent proof of a contractor's commitment to quality.

The British Security Industry Association is the trade association for the professional security industry in the UK. Our members are responsible for more than 70% of UK security products and Services (by turnover) including the manufacture, distribution and installation of electronic and physical security equipment and the provision of security guarding and consultancy Services.



As the voice of the British private security industry, the BSIA mission is to support members and encourage excellence; educate the marketplace on the value of quality and professional security; and create an atmosphere in which our members can flourish.


One of the BSIA's top priorities is the maintenance of high standards within the industry, and it places rigorous requirements on companies wishing to become members. BSIA draws up industry codes of practice and technical documents, often then submitting documents for consideration as British Standards.
