More than half of buildings with dangerous cladding have yet to be identified, a major new report has revealed.
The National Audit Office (NAO) said up to 60% of blocks over 11 meters in height were still subject to cladding removal. 
It warns that the government's 2035 deadline to complete the necessary work may not be met.
There is a long way to go before all affected buildings are safe. ”
“Seven years on from the Grenfell Tower fire, progress has been made, but there are still uncertainties regarding the number of buildings that need to be repaired, how much it will cost to repair and how long it will take to repair and recoup the cost of the fire. Considerable uncertainty also remains in the long term.
“There is a long way to go before all affected buildings are safe and there are risks that MHCLG must address if its approach is to be successful.”
not yet identified
Of the 9,000 to 12,000 buildings over 11 meters high that the government estimates need work, 4,771 are on the list, with up to 60% of affected buildings still unidentified.
Of those identified, half of the sites have not yet started restoration work, and about a third have been completed. Of all the buildings that may need work, only 12-16% are still completed.
The pace of repairs to make homes safe is unacceptably slow. ”
Building and Safety Secretary Alex Norris said: 'The pace of remediation to make homes safe is unacceptably slow. We are taking action and fulfilling our promise to ensure that we pay.
“This Government will protect leaseholders and give regulators the power to take enforcement action against building owners who fail to act.”
He also said a “remediation acceleration plan'' would be published soon.
