MCS Technical Working Groups develop the MCS standards, which are predominantly based on international and European standards already in existence.
Solar Thermal Hot Water capture solar energy and convert it into thermal energy (heat). The heat is then transferred to the water in a hot water tank either directly or via a heat exchanger.
Below are the standards required to be met to be able to install Solar Thermal under the MCS scheme. Approved guidance and reference materials to be used with the standards can also be found below.

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.
