PAS 63100:2024 Recommendations
The British Standards Institute recently released the PAS 63100:2024, which outlines that solar batteries should not be installed in voids, roof spaces, or lofts. However, it’s essential to understand that this PAS is not a regulation but can be considered best practice.
Until the new PAS becomes an official British Standard, it remains a recommendation
Official Regulations currently:
Official regulations state, solar batteries can be installed in lofts as long as specific conditions are met, which require a fire and smoke alarm are present, with adequate lighting and Adequate lighting and accessible entry points are ensured. Adequate ventillation is also required to prevent heat build up.
The MCS, will discuss the new PAS in a meeting scheduled for July 2024!
That said the shear weight of these batteries could mean they could fall through the loft without any mechanical fixings, fixing them to the wall, which is seen as best practice. Where possible I prefer them to be outside or in an outbuilding.
