Enhance Your Business Operations

Fire and security solutions can provide a real benefit for your business. Reducing risks and mitigating losses can help make a real contribution to your bottom line. NSI companies will provide you with advice on your initial requirements and work with you to deliver a solution that aligns with your business objectives. Your NSI approved installing company will offer you a contract for maintenance and monitoring. You can be assured the alarm maintenance and monitoring service will operate to NSI standard and be NSI approved. You can choose a different monitoring service if you prefer and, should you do so, you will be responsible for arranging the monitoring contract.

NSI certificates companies who design, install, commission and maintain fire detection and alarm systems, fixed gaseous fire suppression systems and/or portable fire extinguishers. Using the services of an NSI approved company helps you meet your Fire Regulatory requirements by proving you have used ‘competent persons’.
