Fast OH&S certification (ISO 45001)
Need ISO 45001 OH&S certification on a deadline? Start with a short readiness check, then we connect you with the right partner—consultant if you need implementation help, or a certification body if you are audit-ready.
Not sure if you are audit-ready? Start with the questionnaire—it takes a few minutes.
How much does ISO 45001 certification cost?
OH&S certification cost depends on workforce size, hazard profile, and whether you need help implementing the system. Plan for implementation support (if needed) plus the certification body audit.
Typical ranges (North America, SMB)
Certification body audits for a small single-site OH&S system often start in the low-to-mid thousands and increase with headcount, shift work, and higher-risk activities. Consultant support for hazards, legal requirements, and worker participation is separate if you are not ready for audit.
Workforce & risk profile
Higher-hazard operations and larger workforces typically need more audit days than low-risk office environments.
Existing safety practices
Strong hazard controls and records can reduce implementation spend; starting from informal practices usually costs more.
Sites & contractors
Multi-site scopes and contractor-heavy work can expand both implementation effort and certification audit duration.
What it takes to get certified
ISO 45001 certification means your health and safety management system is implemented and evidenced—not just a safety manual on a shelf.
Hazards, risks & worker participation
Hazard identification, risk assessment, controls, and genuine worker consultation are core to the audit.
Legal requirements & competence
You need OH&S legal requirements tracked and people trained for the risks in their roles.
Internal audit & management review
Show the system is checked and leadership is accountable before Stage 1 and Stage 2.
Typical timeline
Audit-ready organizations can move quickly; teams building an OH&S MS often need several months of implementation first.
Your next steps
A clear path to ISO 45001 certification:
Check if you are ready for an audit
Take our short ISO 45001 readiness questionnaire to see if you should talk to a certification body now—or get implementation help first.
If you are ready → certification body
We introduce you to an accredited third-party certification body for your OH&S certification audit.
If you are not ready → consultant, then the body
We connect you with a consultant to help implement your OH&S system, then introduce the certification body when you are ready to certify.
