The refurbishment of Grenfell Tower is a key part of the inquiry under Sir Martin Moore-Bick because the building was clad in materials that, it has since transpired, did not conform to Building Regulations. The cladding system, in conjunction with the insulation material sandwiched beneath it, acted to exacerbate the fire that killed 72 inhabitants on the night of 14th June 2017. Questions need to be answered.

On the first day of the second phase of the official inquiry the organistions listed below were cited by Michael Mansfield QC, representing victims of the fire. They all had questions to answer, he said.

Studio E – the architect

Rydon Maintenance – the design and build contractor

Harley Facades – the cladding subcontractor

Exova –  the fire safety engineer

CEP – the fabricator of the aluminium composite material (ACM) panels

Artelia – the employer’s agent, quantity surveyor and CDM co-ordinator

Royal Borough of Kensington & Chelsea’s Building Control department
