Image source, EPAGrenfell Tower had received a fire risk assessment in June 2016 immediately after a £10m refurbishment was carried out, the BBC has learned.
The tower block was assessed as being a "medium" fire risk, defined as presenting a normal fire risk. Residents however had raised a number of concerns about the risk of fire for a number of years beforehand.
Andrew Goldman, the director of Rydon, the company responsible for the Grenfell Tower's refurbishment, has told ITV's Good Morning Britain: "We don't know there is any direct link between the fire and cladding."

An exploding fridge, and the cladding which was added to the facade of Grenfell Tower during a refurbishment a year ago, have both being cited by a number of residents as possible causes of the fire.
However, the London Fire Brigade has stressed it does not know the cause of the fire at this stage.
London Fire Brigade Commissioner Dany Cotton said it would be " wrong for us to speculate over cause at this moment".
"We will continue to look at the cause of the fire and investigate what happened."

Matt Wrack, general secretary of the Fire Brigades Union, has said normal fire procedures were not possible to follow in the Grenfell Tower fire.
He explained that normally firefighters would work from the inside out but in this case they had not been able to do so. He said it was "shocking" that a fire in a tower block was able to take hold in this way.
