MCS Technical Working Groups develop the MCS standards, which are predominantly based on international and European standards already in existence.
Installer certification includes assessing the supply, design, installation, set-to-work, and commissioning of renewable microgeneration technologies. Similar to the Gas Safe Register, the MCS gives installers a mark of quality and demonstrates to the consumer that the installation will be completed to the highest quality every time.
Approved guidance and reference materials to be used with the standards can be found below and within each technology type.

*The MCS Standards Management Group (SMG) has prepared a guidance document (found above) to assist installers and the wider industry in understanding the intent of how the thresholds, set within each MCS Installation Standard for the heat technologies, shall be practically applied to design, installation and commissioning work under the MCS scheme.
This document has been prepared by the MCS SMG, taking into account the views of the industry to ensure that systems can be adequately designed and installed under the scheme, whilst reinforcing with installation companies the need to ensure they have the relevant competencies to undertake the tasks associated with these systems.
An MCS certified Installation Company should ensure they follow this guidance, and MCS reserves the right to amend the guidance as necessary through periodic review without prior notice.
The 70kWth threshold was noted by the Scheme as a threshold which aligns with the existing competency criteria set out by the Scheme, and other industries such as oil and gas.
