Building owners who fail to remove dangerous cladding have been warned “we are after them” and they could face jail as ministers set a 2029 deadline for action.
The Government acknowledged there could be up to 7,000 buildings with dangerous materials which have not yet been identified, while progress on remediation work on high-rises with known issues has been too slow.
The Remediation Acceleration Plan means that, by the end of 2029, all buildings over 59ft (18m) tall with unsafe cladding that are on a Government scheme will have been remediated.
By then, buildings over 36ft (11m) tall with unsafe cladding will either have been remediated or have a date for completion, with landlords liable for tough penalties if they fail to comply.
Building safety minister Alex Norris told Sky News: “I would want people who own buildings that are watching this, who have not been remediating them, to know we are on them, we are after them, and we want those buildings remediated. And if they don’t, they will feel the force of the law.
“We have a range of powers already, ranging from fines to prison sentences, that can be used in health and safety cases.
“We will use that basket of tools in whatever way with each building to get it resolved. We have committed that that will be the case by the end of this decade.”
Mr Norris acknowledged there are an estimated 4,000-7,000 buildings with flammable cladding which have not yet been identified, more than seven years after the Grenfell Tower disaster which killed 72 people.
Campaigners labelled the Government’s plans as “extremely disappointing” proposals that will “only make a horribly complicated process worse”.
The west London tower block was covered in combustible products because of the “systematic dishonesty” of firms that made and sold the cladding and insulation, inquiry chairman Sir Martin Moore-Bick said in September’s report.
End Our Cladding Scandal, a group representing leaseholders affected by unsafe buildings, said they are “still far from a comprehensive solution” on building safety.
The group said in a statement: “Labour’s Remediation Acceleration Plan is extremely disappointing. These proposals will only make a horribly complicated process worse with further layers of bureaucracy.
“The Government may be patting itself on the back by announcing a target date for all high-rise buildings in government-funded schemes to have been remediated; however, the Building Safety Fund first opened for registrations in June 2020, so a target date of nine years from then is underwhelming.”
“There is still far too much uncertainty. Severe penalties will be meaningless without leaseholders and residents knowing for sure when homes will be made fully safe. This ‘plan’ will do little to change that.”
Deputy Prime Minister Angela Rayner said: “More than seven years on from the Grenfell tragedy, thousands of people have been left living in homes across this country with dangerous cladding.
“The pace of remediation has been far too slow for far too long. We are taking decisive action to right this wrong and make homes safe.
“Our Remediation Acceleration Plan will ensure those responsible for making buildings safe deliver the change residents need and deserve.”
