Although it is not a legal requirement for private landlords to carry out cladding tests, since the Grenfell Tower tragedy it has transpired that almost 150 high-rise buildings in England have failed subsequent tests. 

The Welsh Government has therefore asked social landlords that have cladding with aluminium composite material (ACM) - similar to that used in Grenfell Tower - to have it tested at the same centre which is conducting testing in England.
