What is MCS?

What is MCS and the benefits of using a Certified Installer? If you are interested in generating your own energy, it is important to use an MCS certified Installer so that the technology you choose is specified, installed and maintained correctly.

MCS is a mark of quality. Using an MCS certified installer ensures that equipment meets good standards of performance and that installers are technically safe and competent.

MCS certified Installers have undergone a rigorous vetting process to demonstrate that they adhere to our Standards. These Standards demonstrate a commitment to quality. They will also be a member of a Consumer Code which means strengthened customer protection for you. If your technology is eligible for a government incentive, you will need to be able to provide MCS certification to claim this.


We are proud to have a longstanding, dedicated and loyal workforce who pride themselves on open, professional and transparent renewable solutions who put customers first both within the office and in the field.
