MCERTS Personnel Certification

MCERTS Personnel Certification

The MCERTS personnel competence scheme enables stack-emission monitoring personnel to be formally certified as ‘competent’ based on experience, training and examination.

CSA Group (under Sira Certification Service) operates the scheme on behalf of the Environment Agency and is accredited by the United Kingdom Accreditation Service (UKAS) to BS EN ISO/IEC 17024:2012 ‘Conformity assessment – General requirements for bodies operating certification of persons’.

The scheme has been developed in collaboration with the Source Testing Association (STA) to set the standards for stack emission monitoring.

The scheme provides assurance to regulatory authorities that stack emission monitoring is fit for purpose and capable of providing results of the required accuracy and reliability. Users of the scheme enjoy the confidence that it is formally recognised by regulatory authorities within the UK.

The scheme is split into two components – the certification of personnel and the accreditation of organisations. A quick guide to the scheme can be downloaded here.


CSA Group maintains a database of all personnel certified under the scheme. To confirm the status of a certified person contact CSA Group at
