Why should I choose an NSI approved company?

NSI approved companies sign up to an ongoing programme of independent audits which check they continue to work in accordance with the latest relevant British and international standards and Codes of Practice. NSI approval shows a company’s suitability for approval in many ways including giving consideration to the financial standing of the company, the experience of the directors and staff, effective screening of security staff and the ability of the company to carry out work competently.
