Registrations & Certifications

Our industry accreditations demonstrate our commitment to quality. They’re much more than just a logo on a letterhead: they’re a symbol of the rigorous standards to which we’re held, and by which we operate all aspects of our business.

The National Security Inspectorate (NSI) is recognised as the leading certification body for the security and fire protection sectors in the UK, providing robust, high quality audits of security and fire safety service providers. Businesses who choose NSI approved companies have the reassurance that their chosen contractors will work to the highest industry standards demanded by the Police, Fire and Rescue Services and the insurance industry.


NSI certifications are a family of internationally recognised standards designed to ensure organisations meet the needs of their customers and other stakeholders. The combination of the Quality Management Systems and the relevant sector specific product or service represents the Gold standard of certification. This level holds the greatest perceived value across industry and by the police, fire and rescue services and insurers.
