The total number of high-rise residential buildings of 18 metres or more in height, or at least 7 storeys (whichever is reached first) in England is estimated as of April 2020 to be 12,500.
The Building Safety Regulator will call in new buildings for assessment for the first time within six months of occupation.
Other existing buildings, for example those which have gone through a change of use (eg an existing block of offices converted into flats) will be called in for assessment for the first time within six months of occupation.
There will be a gap between the new regime coming into force and the first buildings being called in for the Building Assessment Certificate.
HSE expect this gap to be no longer than six to twelve months.
