I must be careful about what I say here. We know the owner of a firm which tendered for the refurbishment job at Grenfell (that sort of contract is their main area of business). Their tender quoted for correctly fireproofed cladding and its fitting to accepted standards. They lost the contract by a biggish sum. Someone, some committee, must have gone for the cheapest option, and it must have been a lot cheaper, without understanding the issues. The owner is hoping to be called to give evidence - but doubts it will happen.
