Batteries in plant room and 120 minute fire rated walls

[jimseng]

Just chatting through with building control and the subject of batteries came up. He suggested I need 120 minute fire ratings for the plant room if I have my solar batteries installed inside but I can't find out if this is his recommendation or if there is something written down stipulating this. Anybody have any thoughts? I don't have an outside option.

AFAIK everything to do with battery location and fire protection are all recommendations and there's nothing mandatory.  One thing you want to understand is if your insurer stipulates anything??

@Dillsue Thanks. That is what I was wondering. The whole building control landscape seems pretty vague and based on opinion.

I added mine after sign off, just incase they said variation. Then did what I felt was ok. Most batteries for houses seem to be a safer rather than less safe battery technology now.
