Extension for the use of flat roof solar mounting products

To support manufacturers in gaining product certification to the updated Standard, and to avoid installers temporarily being unable to access certified products for flat roofs, MCS had granted an extension to the use of clause 5.5.5 in The Solar PV Installation Standard (MIS 3002).  

The current interpretation of clause 5.5.5 in relation to flat roofs was permitted until 10 August 2025. However, to allow for more products to achieve certification, and further discussion as you have suggested below, we will soon announce an extension to the continued use of clause 5.5.5. to the 10 November 2025. This will enable installers to register the installation of an uncertificated solar mounting system on the flat roof of a permanent building between now and the 10 November 2025, subject to meeting the requirements stated within clause 5.5.5. After which, Installers will need to select a certified mounting system.
