Feeling safe and secure

This is all backed up by NSI's annual inspection to give you peace of mind that the service you experience will be professional and secure. 

With so many solutions also offering internet enabled apps, it can be difficult to know which are safe and secure for your home. An expert installer can explain the most secure and robust solutions to protect you and your home, including cyber-security.

If you are concerned about crime in your area, you can find out about reported crime rates, practical crime prevention advice and support services in your local area.

*Security companies are also required to conduct necessary employee screening.


Search the NSI Company Finder or ask your NSI approved company for sight of their unique Certificate of Approval for the specific services for which they are approved by NSI.

Insurance benefits

Many home insurers recognise the professional service NSI approved companies provide. A well installed and maintained security system will often enable householders to receive a discount on insurance premiums. Your insurer may ask for a copy of the NSI Certificate of Compliance as proof.  

Check with your insurer whether an intruder home security alarm system, installed and maintained by an NSI approved company will give you a discount on your insurance premium. Sometimes insurers will insist upon this, especially for higher risk situations or those of historical importance.
