What is CM3 Certification and why do I need a CM3 Compliant Plumber?
CM3 is Australia’s leading contractor OHS/WHS prequalification system. It helps businesses like builders, facility managers and corporates engage contractors who meet strict health, safety and compliance standards.
For plumbing contractors, CM3 accreditation provides assurance that your plumber:
- Has documented safe work systems in place
- Meets regulatory and insurance requirements
- Is already prequalified, saving you time and reducing risk
