Corps Monitoring Outperforms NSI Performance Standards In 2025
At Corps Monitoring, we are proud to uphold the highest standards of security monitoring services, as recognised by our National Security Inspectorate (NSI) Gold category 2 accredited Alarm Receiving Centre (ARC).
The certification allows us to monitor any alarm device, ensuring that our clients receive the most comprehensive and reliable service. As we move into 2026, we are delighted to report that we have not only maintained these high standards but also exceeded them across all key metrics, reinforcing our commitment to delivering industry-leading response times.
2025 Performance Highlights
Reflecting on 2025, our amazing team at our NSI Accredited Alarm Receiving Centre has continued to deliver gold-standard service and support. Our achievements reflect both the size of our operation and the professionalism, efficiency and dedication of our highly trained monitoring teams.
- Throughout 2025, our ARC monitored over 7,000 sites, ensuring the safety and security of our customers 24/7, 365 days a year.
- Our team handled more than 3 million alarms during the year, while maintaining an average response time of just 16 seconds.
- We responded to over 25,000 customer emails and answered upwards of 200,000 calls, demonstrating our commitment to fast, reliable and customer-focused service at scale.
Corps Monitoring also surpassed the NSI’s stringent targets across five critical alarm response categories:
- Fire Alarms: The NSI target for fire alarms is to respond within 30 seconds. We achieved an average response time of just 4 seconds.
- Personal Attack (PA) Alarms: The NSI requires responses within 30 seconds. Our team delivered an average response time of 6 seconds.
- Intruder/Other Alarms: For intruder and other alarms, the NSI sets a response target of 90 seconds. Corps Monitoring’s average response time was just 7 seconds.
- CCTV Monitoring: The NSI’s benchmark for CCTV response is 90 seconds. We surpassed this target with an average response time of 35 seconds.
- Lone worker protection: The NSI states a response within a minimum of 10 seconds. We supersede this target with a response time of 3 seconds.
These achievements underscore the efficiency and dedication of our team in ensuring the fastest possible response to all alarms.
False Alarm Filtering
In 2025, we successfully filtered 72% of false alarms, thanks to our advanced detection systems. These systems analyse every activation, enabling us to focus on genuine incidents while maintaining comprehensive records of all triggers. Efficiently managing false alarms is a critical component of our service, as it ensures that genuine threats receive immediate attention.
Our investment in AI technology enhances response times while improving operational efficiency, ensuring our clients benefit from the most effective security monitoring solutions available.
Corps Monitoring’s arc also secured another NSI accreditation last year, achieving Specialist Services Gold Approval for the provision of lone worker services. The certification confirms compliance with BS 8484:2022, the recognised standard for lone worker protection services, alongside ISO 9001 quality management and BS 7858 screening standards, highlighting the organisation’s commitment to delivering safe, reliable monitoring for lone workers.
Looking Forward
At Corps Monitoring, our mission is to meet and exceed the rigorous standards set by the NSI, ensuring our clients always receive the highest level of protection. As we move through 2026, we remain focused on maintaining these exceptional response times, continually refining our processes, and embracing the latest technologies to further strengthen our services.
The safety and security of our clients are our top priority. We are proud to be a trusted partner in protecting their people, property and assets. Alongside this commitment, we have begun trials exploring drone technology and we are assessing how robotics could be integrated into monitoring operations.
As we continue to forge ahead, innovating and enhancing our capabilities, Corps Monitoring will remain at the forefront of the security monitoring industry.
