QMS Templates
To support Installers in putting together a QMS, MCS have made templates available that can be used in conjunction with the relevant Standard.
These templates are for guidance; and don’t strictly need to be used.
Guidance Document MGD 001 provides guidance on how to interpret MCS 001 and, if used alongside the templates, this should help put the necessary documents in place prior to an assessment by your chosen Certification Body for satisfying this Standard.
Installers already using another QMS may be best advised to retain and maintain those systems. Using these templates is not a guarantee of certification, as the assessment will focus on whether the system is complete, effective and properly maintained.
