NSIMercury Fire & Security are fully approved by the 'NSI', or National Security Inspectorate. Our systems are subject to conformity checks on a regular basis in which they are randomly inspected to ensure they meet the high standards set by the NSI.

The National Security Inspectorate (NSI) is an independent, not-for-profit approvals body providing inspection services for the security and fire industries.

For over 30 years, NSI has been protecting the customer by insisting on the highest standards and operating the toughest inspection regime. Companies are inspected regularly by highly qualified, full-time inspectors, to prove their ongoing competence.

NSIs Customer Care support process reinforces the reliability and integrity of the companies it inspects.

All NSI schemes meet or exceed the appropriate requirements of the Police, Fire Service and Insurers.
