Cladding contractor Harley Facades’ work on the fatally-flawed refurbishment of Grenfell Tower was the focus of the inquiry into 2017’s fire tragedy for the second week running this week.

The inquiry heard about a £200,000 estimation error made by the firm in its quote to main contractor Rydon that prompted it to favour the installation of aluminium composite material (ACM) cassettes on the exterior of the west London tower, rather than flat-panel ACM.
