As many as ten Southwark buildings still have Grenfell-style cladding more than three years on from the disaster which killed 72 people.
According to the latest Government data, between six and ten buildings in Southwark have ACM cladding systems unlikely to meet building regulations.
Of those, between one and five are listed as “yet to be remediated.”
The aluminum composite cladding was blamed as a cause for the acceleration of the devastating fire at Grenfell in June 2017.
None of the Southwark buildings with the cladding are council-owned.
Southwark’s Cllr Johnson Situ, who holds the planning portfolio, said the council had spoken to owners of the buildings, and would take legal action if necessary.
“It is a national problem that there are still buildings with potentially dangerous cladding on them and the government should be doing more to support local authorities to tackle the problem in their communities,” he said.
“We have a cross-council team dedicated to ensuring local landlords and building owners fulfil their safety obligations with regards to cladding, and are now working closely with the MHCLG to see which buildings may be eligible for government funding so they can get on with work as soon as possible.”
Nearby Tower Hamlets and Greenwich have more than twenty buildings which carry ACM cladding and have yet to be remediated.
Along with Salford, north-west England, this is the highest in the country.
Last month, a senior government official said it was “clearly unacceptable” that ACM cladding remained on buildings after Grenfell.
Jeremy Pocklington, the permanent secretary of MHCLG, told a parliamentary committee: “At the heart of the problem, too many building owners have not stepped up to their responsibility to make sure that these buildings are safe for leaseholders and for residents.”
