Grenfell Tower fire — recladding lessons and subsequent national recladding programme (ACM cladding remediation programme)
West London, UK · 2017-ongoing (fire June 14, 2017; renovation 2016; remediation ongoing) · 2016 renovation £8.6 million; Government announced £200 million for ACM cladding remediation in May 2019.
The judgement call
Account action unavailableUse of highly combustible ACM cladding with polyethylene core, despite known risks and bans in other countries. - Manipulation of testing processes and misrepresentation of test data by manufacturers (Celotex, Arconic). - Failure of certification bodies (BBA, LABC) and oversight (UKAS) to ensure product accuracy. - Government's deregulatory agenda prioritized over fire safety, ignoring warnings and recommendations. - Establishment of the Building Safety Act, Building Safety Regulator (BSR), National Regulator for Construction Products, and New Homes Ombudsman. - Legal protections for leaseholders from historical safety defects.
Key engineering challenges
Rapid fire spread due to combustible ACM cladding with polyethylene core. - Inadequate fire safety procedures and lack of automatic sprinkler systems. - Single central staircase for egress. - Systemic failures in government oversight, code compliance, and product certification.
