The Department publishes data on the number of high-rise residential and publicly owned buildings in England with Aluminum Composite Material cladding systems unlikely to meet building regulations. The latest data is available here . The Department has commenced a data collection exercise which will enable us to build a picture of external wall systems in use on high rise residential buildings. The exercise will collect data on residential buildings 18 metres and over covering private and social buildings, student accommodation and hotels. We will publish appropriate summary information from the data collection in our monthly Building Safety Programme data release when ready.
