I havent followed the forum in a while so was blindsided by this news as it hasnt been widely publicised.

Im quite shocked at the level of restriction placed on battery storage systems given the incidence rate of fires within properties.

Where does this leave previously installed systems. The introduction of this British Standard is clearly going to influence insurers and so existing installtions may have to be updated. Is their guidance on this?

About 50% of our installs have been outside. I like them (apart from the worry about rodent damage to cabling).

However, that leaves 50% that cant be easily located outside. Mostly terraced houses. 
From what ive read, the changes for ESS require:

1) any indoors located battery systems (in non 6.5.5 locations) to have open air ventilation. Is this dedicated or a trickle vent?

2) fire detection systems upgraded to LD2 throughout the property. Fire detection to be upgraded if necessary and signed off to standards of 5839-6. LD2 not to be confused with the basic LD3 standard of escape routes only.**

**Note this requirement applies to inverters sited in lofts. Again is this retrospective?

Sadly does seem to have been missed by a  not insignificant number - the socials have started to pick up on it now…

I missed the comment phase…

Yes, I think it featured in a popular electrical industry news bulletin earlier this week.
