Welcome to Solar Slate Plate.
Polite Notice : MCS 012 Issue 3.0.
The new MCS 012 standard issue 3.0 was implemented on the 10th May 2025. Solar Slate Plate are unable to be compliant with the new standard MCS012 Issue 3.0 in its current form. Certifying bodies are not certifying components anymore, although the standard allows for such products to be certified and have done in our case for almost 9 years. Our certifying body of 9 years informed us that they are no longer certifying components.
We are pleased to let you know that after our persistent efforts, MCS has just updated its announcement. They have removed the original clause–
” Installations must use a product that was purchased from the manufacturer prior to the certification ending on 10th May 2025. “
Please refer to this link for your reference.

affected-solar-mounting-products/
This means we can continue selling our products until the Grace Period ends on 10th November 2025.
We are currently trying to reach a resolution with MCS regarding our position and are also looking at alternative approaches such as Flexi-Orb certification that will also allow for the Smart Export Guarantee, (SEG).
We have served the solar industry for over 10 years and feel that we have provided innovative solutions to solve various issues regarding weathertightness etc.
We need your help if we are to continue supplying MCS certified products after 10th November 2025. We are essentially being prevented from re-certifying our products despite the new standard allowing our products to be certified. Solar Slate Plate wishes to continue serving our industry by continuing to provide MCS certified products. We ask for you to contact MCS and let them know your thoughts. Please contact the MCS Helpdesk on 0333 103 8130 or email hello@mcscertified.com. We believe that the actions being taken by MCS and the certifying bodies in regards to MCS012 issue 3.0 are wrong and are potentially restricting consumer choice for previously existing certified products that have been in the industry for over 10 years..
We will provide further updates in due course.
Apologies for any inconvenience caused.
From 2016 our roof mounting systems have been fully tested and approved to MCS012 standards for 9 years. From 10th May 2025 we are no longer certified.
Solar Slate Plate and ERIC-TILE are quick and simple to use, with no fuss and no mess.
Solar Slate Plate’s innovative designs help to reduce installation times and eliminate health and safety risks and issues.
You don’t need to use mastics or sealants to provide weatherproofing. If breakages do occur, you won’t have to purchase replacement slates or tiles that add extra costs, as the Solar Slate Plate and ERIC-TILE are direct replacements of the slate or tile, leaving you with plenty of spares. Both products are simple to use and are supplied with all of the roof screws/components required to fit to the roof’s structural members.
Our mounting systems are based around the knowledge that not every installers methods of making a roof weatherproof are the same. With our products, there is only one way of fitting them, so the quality of every installation will remain the same, regardless of the installers experience, which also helps to eliminate costly return visits.
Finally, products that are specific to the problem, that installers can be confident in using.
Solar Slate Plate really do make solar pv/thermal installations on roofs easy.
