A partner in the firm responsible for fitting the new insulation and cladding to Grenfell Tower has told the inquiry into 2017’s fire that “he can’t see how” cavity barriers were installed the wrong way around and back to front as part of the flawed refurbishment.

Grahame Berry of subcontractor Osborne Berry denied the firm had struggled to get enough qualified workers for the refurbishment, which led to the loss of 72 lives, when he appeared before the Grenfell Tower Inquiry yesterday.
