The Private Security Services Act 2004 requires that all security companies have a Private Security Contractors Licence issued by the PSA.  The PSA require proof that companies meet the appropriate Irish and European standards. This proof is demonstrated by being approved through an accredited certification body such as CerticCS. CerticCS approved companies meet these requirements and demonstrate this on an ongoing basis by undergoing regular rigorous audit by expert auditors.

For security systems, once a CerticCS installer has been licensed the company’s details are passed to the Gardai who in turn will set up a system for responding to alarm activations from monitored installations put in place by the CerticCS approved installer. You can rest assured your CerticCS installer will issue you with a Certificate of Compliance and apply for alarm monitoring, Gardai or keyholding response on your behalf as necessary.

Many CerticCS approved companies also operate Management Systems such as ISO 9001 (Quality Management System), ISO 14001 (Environmental Management System) and ISO 45001 (Health and Safety Management System).

These provide additional evidence of the company’s commitment to high standards of service, quality and continual improvement.

Further guidance regarding PSA Standards can be found on the PSA website.
