The National Security Inspectorate (NSI) is the UK's leading approvals and certification body that provides inspection services for the UK's fire and security industries. Approved companies are regularly inspected to ensure they comply with the appropriate British and European Standards and NSI Codes of Practice.
NSI has provided certification services for over 35 years, making a major contribution raising standards in the customer. Throughout it history, NSI has adapted and developed its services to keep pace with the new technologies, relevant legislation and ever-increasing customer needs and expectations.
Today, NSI's owl brand is widely recognised as the benchmark of quality in the fire and security sectors and is a symbol that buyers and specifiers can trust. NSI approval is only given to companies that are to consistently meet our exacting standards.
Whilst we work closely with the Government bodies, such as the Security Industry Authority (SIA), we also work with the Police, Fire and Rescue Services, insurance companies and the fire and security industries and their customers, whilst remaining steadfastly an independent, not for profit body. This allows us to focus on raising standards within our specialist areas, being free from the vagaries of politics and shareholder demands enabling us to develop our role as industry leader and protector of the customer's right to expect a first class service.
