Periodic Verifications
Periodic Verifications are essential inspections that ensure your building’s electrical infrastructure—such as switchboards, cabling, and componentry—is correctly specified and safely handling its intended load. These checks help prevent electrical faults, reduce fire risk, and ensure compliance with New Zealand’s Electrical Regulations.
IQP Inspections
IQP Inspections (Independent Qualified Person) are part of your building’s Warrant of Fitness (BWOF) requirements. These inspections cover critical emergency systems including emergency lighting, exit signage, fire suppression systems, and evacuation routes. Regular IQP checks are mandated to ensure these systems are functioning correctly and ready to protect occupants in the event of an emergency.
