I’ve held this ACS certificate before – can I enrol in the Refresher version of the course?

Yes, if you currently hold the ACS Core Domestic Gas Metering (CMA3) certificate and it hasn’t yet expired for 12+ months, you can enrol in the Refresher version of this course.

If you hold an ACS Core Domestic Gas Metering (CMA3) certificate that has expired for over 12 months, you will need to enrol in the Foundation version of the course to renew your certificate, regardless of your professional experience.
