Philip Hammond, the Chancellor, claimed on the Andrew Marr Show on 18 June 2017 that the cladding that was used on Grenfell tower is banned in the UK:
Was he right?
I will argue here that, from a practical point of view, this flammable cladding cannot legally be used in the UK on buildings over 18m in height. It is not that there is an explicit ban on the material. It is more that there is no way that it could ever meet the requirements of the Building Regulations, at least as interpreted by the standard industry guidance. From a practical point of view, it is not a marginal question. Aluminium composite panels with a polyethylene core are highly combustible and should never be used on high buildings. If, as has been reported, these panels are in place on other tower blocks, they should be removed immediately, or the residents evacuated.
