NSI Re-certifications – September 2026

Looking for NSI approval?

Congratulations to the following organisations who successfully achieved their NSI re-certification in September 2026 for one or more approval schemes.

Re-certification audits occur at 3 yearly intervals and take place prior to the expiry of a company’s Certificate of Approval. The re-certification audit verifies a company’s ongoing demonstration of competency and professionalism and their commitment to NSI’s programme of annual audits for another three years.

Buyers who contract NSI approved companies for their security and fire safety needs can be assured of security and fire safety services delivered to the highest standards by businesses committed to quality and continual improvement.
