S4 Mounting System is now fully MCS-certified with over 2,200 panel references!
Since 2023, when BS EN 15725 was updated, installers and manufacturers have been working hard to understand and comply with the new requirements for selling and installing in-roof mounting systems. With major changes to the testing process, each panel part number now needs to be individually tested, making compliance more demanding than ever.
These changes quickly created gaps & installation delays, with many popular and newly launched panels left without approved test certificates. This left many installers with the crucial question, ‘Which panels can I actually install compliantly?’
A clear answer for installers
For installers choosing the S4 Mounting System, there’s now a clear answer. Combining high quality with great value, S4’s new BBA certificate (BBA 7468, 25/7499) covers over 2,200 panel references and has now been officially recognised by MCS.
