The National Standards Authority of Ireland is advising homeowners and businesses to only use certified security system installers when getting an alarm or CCTV fitted in their property or premises.  The warning comes after an unlicensed security systems’ installer was convicted at Naas District Court on Monday (July 4th) under Section 37 of Private Security Authority Act.

  • There are over 1,100 certified alarm installers in Ireland
  • Don’t take a trader’s word for it. Check the PSA register for all licenced installers
  • Using an unlicensed security systems installer may invalidate your insurance cover

Liam Whoriskey trading as Whoriskey Security Systems, based in Newbridge, Co Kildare, was given an eight month jail sentence by Judge John Coughlan for providing a security service without a licence.  Mr. Whoriskey was subsequently released on bail pending an appeal.

Mr Whoriskey had been prosecuted by the Private Security Authority (PSA) on two previous occasions in 2010 and 2012.  The latest prosecution arises from an extensive investigation by the PSA’s inspector into the installation of intruder alarm and CCTV systems by unlicensed operators. 

Chief Executive of NSAI (National Standards Authority of Ireland), Maurice Buckley said it is vital homeowners and businesses check the Private Security Authority’s register and only use licenced security system installers. 

“It is illegal to operate a security systems service without a licence.  Therefore it is crucial businesses and householders realise that using an unlicensed installer may invalidate their insurance cover,” said Mr. Buckley. 

“As an accredited Certification Body, NSAI audits and certifies installer companies.  This certification is a necessary prerequisite for them to obtain their licence from the Private Security Authority.  We‘re encouraging anyone thinking of getting an alarm or CCTV installed in their home or business to do their research and check the register of licenced traders before buying.  You should also make sure you receive a Completion Certificate once the device is installed,” he added. 

Certification for Security Systems

NSAI operates a certification scheme based on the Irish standard I.S. EN 50131 for alarm systems, intrusion and hold-up systems.  Learn more at I.S. EN 50131 

All certified installers are required to issue a Completion Certificate with each installation.  The original Completion Certificate should be given to the client, with a copy provided to the insurer of the premises.  If the installation is monitored, a further copy goes to the nominated monitoring centre, so that the Garda Siochána can arrange to respond to any activations of the system.  As certified installers are required to install only certified systems, all clients are entitled to receive a Completion Certificate.

The Private Security Authority is the statutory body with responsibility for licensing and regulating the private security industry in Ireland.  The Private Security Authority provides a register of all licensed contractors.  

There is currently over 1,100 licenced security system installers in Ireland.  Householders and businesses should check the register on the PSA website,, before engaging an intruder alarm, CCTV or access control contractor to install or service their system.
