Somebody shared this from September 2016, from the Grenfell Action Group.
Lots of links on the original article if you want to check them out.
EDIT: somebody referred to a resident saying the fire started from his fridge exploding? That's an odd thing for a fridge to do unless it is very very old. Given this article refers to faulty wiring in this very block back in 2013 we may already have a very good idea of the cause.
Too early to speculate yet, until the relevant investigation, but just wanted to comment on this.
A certain well known fridge manufacturer (who I shall not name here) has had multiple reports and issues of newly manufactured fridges catching fire, and all in the last year or two.
There's been numerous reported cases in the press.
So it doesn't necessarily have ot be an older appliance.
Again, at the moment, it's an anecdotal report, so lets wait until the relevant authorities tell us more.
