How To Get Certified & The Certification Process

SMI Certification offers its certification service against the internationally renowned standard for OHSAS Management System ISO 18001.  Our certification system is built on the following processes:


Applications are received preferably by e-mail or post.  All applications are reviewed and we check that we have all the information necessary before we provide a quotation.  Applicants can request a further clarification to aid their decision making process.

Applicants can proceed at their own pace to prepare to meet the requirements of the lastest version of ISO 18001.  When they are ready for assessment, the dates are arranged to suit our clients. 





The certification audit takes place in two parts:

Stage 1 - Audit (Stage 1)
Stage 2 - Audit (Stage 2)

The Stage 1 Audit involves a desk audit of documentation and an on-site visit to witness the readiness of the organization for the Stage 2 Audit.

After a stage 1 audit, a report is issued to identify the degree of readiness and give time to the client to improve the management system before the Stage 2 Audit.

The Certification Stage 2 Audit (Initial Certification) involves a full review of the company’s implementation of their Management System.  The duration of the audit allows a detailed review of records and documents used to provide evidence that the organisation’s processes are controlled and have predictable outcomes.  The outcomes of the processes need to show that they meet customer expectations as well as the objectives and policies set by the organisation’s management. 

Through the Plan – Do – Check – Act process, the organisation is expected to identify and implement appropriate improvements to the system and the predictability of its outcomes. 

SMI Certification will issue an audit report at the end of the Stage 2 Audit as well as a recommendation for the outcome of the audit.  However, before proceeding to grant certification, the applicant has to analyze any major/minor issues raised and, for each:

  • identify the cause of the issue,
  • advise how the issue has to be corrected, and
  • show what was changed in  the management system to eliminate or reduce the risk of the same issue reoccurring

If there are major issues raised, it might be necessary to re-visit the site to ensure satisfactory closure.

When SMI Certification receives a satisfactory response from the applicant, the file is independently reviewed by SMI Certification Board who takes the decision whether or not to award the Certificate.


At least once a year, SMI Certification visits each certified company and ensures that the management system is being maintained and that it is achieving its expected outcomes.  At each visit, part of the management system is reviewed in depth.

There is a certification cycle of three years (as indicated by the expiry date on the certificate) and, before the certificate expires, a more detailed review is undertaken.  This re-certification reviews the performance of the whole management system and ensures that every element of the system is performing satisfactorily; the results of the previous audits are taken into account.

The issues raised at the re-certification are handled the same way as at the end of the certification process.  When a satisfactory response is received, a certification decision is taken by SMI Certification Board and a new certificate is issued.

Any changes during the 3-year certification cycle are normally reviewed and audited during routine surveillance events.  In cases where change leads to the breakdown of the system, SMI Certification reserves the right to suspend or withdraw certification.


Impartiality and confidentiality are cornerstones of SMI Certification services.   SMI Certification guarantees the confidentiality of their certification services and ensure that the service is fully impartial.


SMI Certification is committed to ensuring the impartiality of its certification services and actively manages any threat of actual or perceived conflicts of interest affecting its certification services, its management, staff and auditors and the activities of any associated functions.  SMI Certification impartiality is monitored by a dedicated Impartiality Committee set up by the Standards and Metrology Institute so to provide an oversight of SMI Certification activities in particular to the impartiality of its certification services.

Any queries relating to impartiality should be addressed to the Head of SMI Certification.  These will be reviewed by the Chairperson of the Impartiality Committee.
