Cladding and insulation combinations from more than 100 buildings have now failed the comprehensive fire safety tests.
Of the samples from 111 buildings which the Department for Communities & Local Government said “does not meet current building regulation guidance”, 90 are local authority or housing association owned or managed.
LGC understands about a third of the 90 buildings are owned or managed by 15 councils.
DCLG has issued detailed advice to those which own or manage affected properties. A section outlining what advice or support is available does not mention government funding any of the remedial work to ensure buildings are safe.
Simon Blackburn (Lab), chair of the Local Government Association’s safer and stronger communities board, said: ““The tragedy at Grenfell Tower has clearly exposed a systemic failure of the current system of building regulation. The government must commit to meet the full cost to councils of removing and replacing cladding and insulation systems. It is also imperative that this testing process moves quickly to identify what landlords should be replacing these systems with as soon as possible.
“With these latest test fails affecting buildings owned by a range of different landlords across the country, the government also needs to make sure there is capacity within the housebuilding industry to take quick action to carry out the scale of remedial work that looks likely to be needed.”
LGC reported last week how the government has launched an independent review of building regulations and fire safety.
