BS OHSAS 18001 Certification

BS OHSAS 18001: Effective occupational health and safety

Safety at work is one of the most important assets in all industrial sectors – for both employees and employers. The obligation to protect health and life by taking adequate safety precautions and detecting potential risks in good time comes first of all. But occupational health and safety is much more than this and also has a sustainable impact on company profits by preventing costly sick leave and machine downtimes.

Since 2007, British Standard BS OHSAS 18001 has been applicable. However, it will soon be replaced by its successor, International Standard ISO 45001, and on 30 September 2021, existing certificates based on BS OHSAS 18001 will lose their validity. The deadline has recently been extended by 6 months due to the COVID-19 outbreak. Organisations certified according to BS OHSAS 18001 can change over to the new standard within the framework of a recertification or surveillance audit.   

Why occupational health and safety? Your benefits.

  • Accidents at work are prevented and sick leave reduced
  • The motivation of your employees increases
  • You can be sure to fulfil statutory requirements and achieve legal compliance
  • High safety standards give you a competitive advantage
  • Certification as part of an integrated management system helps to save costs and optimise the efficiency of your corporate management

FAQs on the transition from BS OHSAS 18001 to ISO 45001

When and how will the transition from BS OHSAS 18001 to ISO 45001 take place?

The transitional period will end on 30 September 2021. Once this transitional period has expired, as from 01 October 2021, all accredited certifications based on BS OHSAS 18001 will no longer be valid.

Certified companies and organisations have to change over to the new standard, ISO 45001, within the framework of a recertification or surveillance audit, and must also successfully implement the changed requirements.

Is an initial certification according to ISO 45001 more cost effective than a transition from BS OHSAS 18001 to ISO 45001?

For organisations of certain sizes, the additional time and costs can be less in a certification audit than in a recertification or surveillance audit. Please contact us in order to find out about your own particular case. 


What is the procedure for transfer from another certification company?

First the transfer audit is carried out and a certificate is issued based on BS OHSAS 18001. Soon after issuance of the certificate the transition can be made to ISO 45001 by means of an audit. The same rules as for a transition in a recertification, surveillance or special audit apply to the extra time that is needed. Organisations can also carry out the transfer with standard BS OHSAS 18001 and then change over to ISO 45001 in the next surveillance audit.

How much extra time is needed for transition within the framework of a surveillance or recertification audit?

The time needed by an organisation for transition to ISO 45001 depends among other things on the maturity and effectiveness of the current health and safety management system. For this reason, performance of a gap analysis is urgently recommended in order to determine the internal need for action and to assign the necessary resources and the schedule.

The International Accreditation Forum (IAF) specifies the additional time needed for transition to ISO 45001 as one audit day at least. More time is needed for large and complex organisations.
