Who ISO 45001 is for
When the buyer needs proof that safety is managed.
Managing directors usually come to us when a tender, major customer or main contractor requires ISO 45001 before they can be considered for work. The certificate gives the buyer independent evidence that your occupational health and safety management system has been audited.
Tender and procurement teams
For a tender submission or vendor pre-qualification that names ISO 45001, workplace safety or a certified safety management system.
Construction, M&E and maintenance firms
For businesses whose teams work at client sites, around live services, at height or alongside other contractors.
Manufacturing, logistics and warehouse teams
For operations managing machinery, vehicle movement, manual handling, chemicals, shift work or contractor activity.
Businesses moving up from bizSAFE Level 3
For teams that already have Risk Management records and need the wider ISO 45001 system, including leadership, worker participation and continual improvement.
Before we quote. Send the tender or customer requirement, business activity, headcount, sites, main hazards and target date. After a short call or site visit, you receive a written quote that sets out the safety-system work, the documents and people needed from your team, and the project timeline.
ISO 45001 certification process
Build the safety evidence before the two audits.
We start with the work that must sit inside the certificate scope. Your team shows us the activities, hazards, sites and existing safety records. We then close the gaps, put the agreed system and records into normal work, complete the internal audit and management review, and prepare for the certification body's Stage 1 and Stage 2 audits.
- 01Confirm the scope
You send the requirement and confirm the business activities, sites, headcount and target date. We define what the certificate needs to cover and what your team must provide.
- 02Review the safety gaps
We compare your current safety practices, hazard controls and records with ISO 45001:2018. We set out the actions, owners and documents needed for the agreed scope.
- 03Build and use the system
We prepare the policy, hazard and risk records, legal register, procedures and other agreed documents around how your people work. Your team uses the records in normal operations.
- 04Internal audit and management review
We check the system with you before the certification body does. Your team records findings, actions and management decisions, then we brief the people who may be interviewed.
- 05Prepare for Stage 1 and Stage 2
Stage 1 reviews whether the safety management system is ready. At Stage 2, the independent certification body samples evidence, walks the workplace and speaks with staff about how the system is used.
ISO 45001 deliverables
The safety documents, people and records behind the certificate.
We agree the document list after reviewing your certificate scope, activities, sites and existing records. You receive the safety-management documents needed for that scope, guidance for the people using them, and an audit file built from records your team has used in normal work.

ISO 45001 consultancy cost
From $2,288, with audit costs shown separately.
ZES ISO 45001 implementation consultancy starts from $2,288. Your final fee depends on headcount, sites, risk profile, certification scope and the safety documents or records already in place. After a short call or site visit, we provide a written quote for the work required.

ISO 45001 audit preparation
What we check before the auditor visits your workplace.
The certification body is independent from ZES. At Stage 1 it reviews whether the safety management system is ready. At Stage 2 it samples records, walks the workplace and speaks with staff. Before those audits, we check that the system reflects the safety work your people actually do.
The certificate scope matches the work
The sites, business activities and people named in the scope match the work the certification body will see and sample.
Hazards lead to controls
Your risk assessments cover the activities inside the scope and show the controls, action owners and reviews your team uses.
Legal requirements are considered
The legal register identifies the Workplace Safety and Health requirements relevant to your work, and your team can show how they are considered.
Workers can explain their part
The staff and worker representatives the auditor speaks with understand the hazards, controls, reporting route and records relevant to their work.
Records show normal use
The auditor can follow evidence from normal work, such as training, consultation, inspections, incident reports, corrective actions and reviews.
Internal audit and management review are complete
Your team has checked the safety management system before the certification body does, recorded findings and actions, and reviewed the system with management.

ISO 45001 questions
Costs, timing and the certification audit.
Short answers for Singapore managing directors and project leads. For the readiness work in more detail, read the ISO 45001 gap-analysis guide.
What is ISO 45001 and why would a tender ask for it?
ISO 45001:2018 is the international standard for an occupational health and safety management system. An independent certification body audits the system before issuing a certificate. In Singapore, tenders, main contractors and major customers may request it as evidence that workplace safety is managed systematically.
How much does ISO 45001 certification cost in Singapore?
ZES implementation consultancy starts from $2,288. Certification-body Stage 1 and Stage 2 audit fees are separate and the live page states typical SME fees of $2,000 to $4,000. The typical first-year total stated on this page is $4,500 to $9,000, depending on headcount, sites and risk profile.
How long does ISO 45001 certification take?
Most SMEs working with ZES are certified in two to four months. This includes building and using the safety management system, internal audit, management review, then the certification body's Stage 1 and Stage 2 audits. Several sites, more work activities or unavailable staff can add time.
What does my team need to do?
Send the tender or customer requirement, business activity, headcount, sites, main hazards and target date. Nominate a project contact and make the people responsible for operations, safety and management decisions available. Your team confirms the scope, reviews documents, uses the agreed records, joins the internal audit and management review, and is available for certification-body interviews.
Who audits and issues the ISO 45001 certificate?
An independent accredited certification body, not ZES, audits the safety management system and issues the certificate. At Stage 1 it reviews the system; at Stage 2 it samples evidence, visits the workplace and speaks with staff. ZES prepares the documents, internal audit, management review and team briefing. The certification body makes the certification decision.
What happens if the auditor raises findings?
Your team addresses the findings and provides the evidence the certification body requests before certification can be issued. We help you work through the points and prepare the evidence. The certification body decides when its requirements are met, so we do not promise an audit outcome.
We already have bizSAFE Level 3. Is ISO 45001 a big step up?
It is a wider management system. Level 3 focuses on your Risk Management implementation and audit. ISO 45001 also covers leadership, worker participation, legal requirements, objectives, performance review and continual improvement. Your Level 3 risk assessments and controls are useful starting evidence, and we build the wider system around them.
Can ISO 45001 help us get bizSAFE Star?
Yes. An SAC-accredited or MRA-recognised ISO 45001:2018 certificate, together with a Risk Management Audit Report, is required for bizSAFE Star. We can plan the ISO 45001 work alongside the bizSAFE Star route so your tender and safety requirements are clear from the start.
Can we combine ISO 45001 with ISO 9001 or ISO 14001?
