Safety checks that left thousands of people unable to sell their flats after the Grenfell disaster are being eased.
Housing Secretary Robert Jenrick said homes without cladding would no longer need an EWS1 external wall safety certificate - which involves a survey.
Thousands of people have been refused mortgages on flats because owners have been unable to get the surveys done.
But mortgage lenders said they "did not consent" to the announcement of the changes.
They also questioned how many homeowners would benefit.
The checks were introduced after 72 people died at Grenfell Tower when a fire spread along outside walls.
To begin with, only those who owned flats in tall buildings with dangerous flammable cladding were affected. But in January the government extended its advice to smaller properties and mortgage lenders began demanding fire surveys from a much wider range group of sellers.
Cladding red tape 'stops people selling homes'
Imprisoned by cladding: The flat owners who cannot sell
With fewer than 300 qualified surveyors for hundreds of thousands of properties, many owners have been unable to access them, leaving them stuck, unable to sell or remortgage.
Earlier, Mr Jenrick announced he had "secured agreement" that the survey would not be needed for homes without cladding.
"Through no fault of their own, some flat owners have been unable to sell or remortgage their homes, and this cannot be allowed to continue," he said.
The housing secretary said the decision to ease checks for blocks without cladding would help almost 450,000 homeowners who "may have felt stuck in limbo".
The building safety minister Lord Greenhalgh tweeted that the chairman of the lenders association UK Finance, and the chief executive of the Building Societies Association, had confirmed "EWS1 forms are not and have never been required" for buildings without cladding.
Despite that some people without cladding, have previously been asked to obtain an EWS form and both bodies said in a statement they "did not consent" to being included in the announcement.
