About MCS

MCS is a mark of quality and demonstrates
compliance to industry standards that companies
strive to meet. It highlights to consumers that
companies are able to consistently install or
manufacture to the highest quality every time.

MCS has today updated a number of installation and product standards. The changes to the standards include: 

  • Update to the definitions in all standards to align with a review undertaken by the Standards Management Group
