A new regulator will be established with powers to ban the use of dangerous building materials, following evidence at the Grenfell Tower Inquiry that manufacturers covered up safety issues. They have also ordered a review of product testing because of "abuses" in the testing system.
It will be able to prosecute companies that flout rules, the government said.
Ministers have called revelations at the inquiry into the Grenfell Tower fire "deeply disturbing".
Housing and Communities Secretary Robert Jenrick said it was "already clear that action is required now". Jenrick said: "The Grenfell Inquiry has heard deeply disturbing allegations of malpractice by some construction product manufacturers and their employees, and of the weaknesses of the present product testing regime. We are establishing a national regulator to address these concerns and a review into testing to ensure our national approach is fit for purpose."
