A series of fire safety tests designed to probe cladding systems on high-rise towers have concluded, finding 228 buildings at risk across the UK, the Government said.

In the final raft of assessments, ordered in the wake of the Grenfell Tower inferno, a combination of Aluminium Composite Material (ACM) cladding with a limited flammability filling and stone-wool insulation was deemed safe.

No buildings in the UK are known to have this mixture of materials, but the Department for Communities and Local Government (DCLG) said it could act as a solution for structures with dangerous cladding.

It is understood that the last cladding system examined was considered the least dangerous option out of the seven tested.

The so-called "whole system" tests were designed to see how different cladding systems reacted in a fire, before determining if they complied with building regulations.
