ISO 45001 Occupational Health & Safety Certification
ISO 45001 is the world's leading standard for occupational health and safety management. Responsible Business Assessment Limited provides independent, rigorous certification audits that demonstrate your organisation protects its workforce consistently and diligently.
What is ISO 45001 and why does it matter?
ISO 45001 is the international standard for occupational health and safety management systems, published by the International Organization for Standardization. It sets out a structured framework for eliminating hazards, reducing risk, and protecting workers and other people affected by your operations.
Certification demonstrates to employees, regulators and clients that your safety management system is independently verified — not just documented, but genuinely operating and effective. For organisations bidding for contracts, managing contractors, or operating in higher-risk sectors, ISO 45001 certification is frequently a stated requirement rather than a discretionary advantage.
Responsible Business Assessment Limited carries out a structured, two-stage audit against the requirements of ISO 45001:2018. Certification is issued on successful completion, with ongoing surveillance audits to confirm the system continues to operate effectively year on year.
Supporting the UN Sustainable Development Goals
Fewer workplace incidents
A structured OH&S system identifies hazards proactively, reducing incidents, injuries and associated liability.
Lower insurance and absence costs
Reduced incident rates translate directly into lower premiums, claims and lost-time absence.
Compliance and duty of care
Certification provides structured evidence that legal and regulatory health & safety duties are being met.
Stronger worker engagement
Worker participation is embedded in the standard, improving morale, trust and reporting culture.
Structured hazard and risk control
Clause 6 requires formal hazard identification and risk assessment across all operations and roles.
Access to safety-critical tenders
Many principal contractors and public bodies require certified OH&S systems from their supply chain.
Organisations that benefit from certification
ISO 45001 is sector-agnostic. Its requirements are written generically enough to apply to any organisation with people at work, and are then implemented through processes specific to that organisation's operations.
What we audit
The ISO 45001:2018 core clauses
ISO 45001:2018 is structured around seven auditable clauses. Our assessors evaluate objective evidence against each, and record findings in a formal audit report.
