ISOQAR > ISO 45001 > Migrate From OHSAS 18001 to ISO 45001

OHSAS 18001 is being withdrawn in March 2021

OHSAS 18001 has been replaced by ISO 45001, the first international standard for occupational health and safety management systems (OHSMS). This new standard was published in March 2018.

To maintain your certification when OHSAS 18001 is withdrawn, you need to plan how you are going to ‘migrate’ to ISO 45001.

Alcumus ISOQAR has produced a range of tools to support you through this process which you can read about below. Of course, you can always just give us a call or email us if you’d like to talk this through with us.

Why migrate early?

You can of course migrate at any time you wish, but there are strong benefits to migrating early.
  • Gain an advantage over your competitors by being an early adopter
  • Introduce better risk management processes
  • Integrate better with other management systems if you have, for example, ISO 9001 or ISO 14001


We have created a useful ISO 45001 Gap Analysis Checklist which will give you an indication of how ready you are for your ISO 45001 certification audit. It’s for you to use yourselves, in-house.
You can download the ISO 45001 Gap Analysis Checklist here.




Once you have performed your own in-house gap analysis, you may want to talk it through with an Alcumus ISOQAR Auditor on a Migration Guidance Call to get their professional opinion.

The 60 minute guidance call (telephone or Skype) and follow-up contact report will help you to:
  • build your migration project plan and prioritise associated actions
  • understand the likely resources required for successful migration
  • determine training needs and paths for those responsible for implementing and maintaining ISO 45001

The cost for this is £295 which will be deducted from subsequent pre-certification services for ISO 45001, including and limited to one of the following:
  • Standalone migration audit
  • ISO 45001 Starter Pack
  • 1 day on site pre-assessment
To arrange a Migration Guidance Call, email us or call 0161 866 6182


We have a wide range of ISO 45001 training courses available through the Alcumus Academy. We’ve got them at every level from awareness training through to lead auditor. They’re running on a regular basis at carefully selected venues nationwide. And of course, they’re delivered by our inspiring, experienced trainers who have vast knowledge in the field and understand the challenges you are facing.



You may already have a preferred Consultant who supports you. If you don’t, then you can always seek support from the Alcumus ISOQAR Associate Network.

If you would like to speak to us about any of the migration tools listed above or indeed if you have any other certification question, please call 0333 355 9199 or email
