Let me again correct the record. I do not know whether the hon. Gentleman was absent in December, but he should know that we have banned desktop studies, and restricted them in other circumstances, to try to discourage their use. We did that before Christmas.
The hon. Gentleman made a good point about the effect of insulation combined with cladding. Our ban on the use of combustible materials on buildings more
than 18 metres high applies to everything that makes up the skin of a building, and that includes the insulation, not just the cladding. The 18-metre rule was of course introduced on the basis of advice from the expert panel. As I have said, if there is evidence to show that there are significant dangers to buildings that are less than 18 metres high, we will of course be happy to look into it.
I realise that Labour Members are trying to make this point, but I want to dispel the idea that we are complacent, because that is absolutely not the case. An enormous amount of effort, time and energy has been put into getting this right, and a large number of voices have been prayed in aid.
The hon. Gentleman is correct in saying that a defective industry has grown up over the last 20-odd or 30 years, under Governments of all stripes. As I said yesterday, the Grenfell disaster lifted a big flat rock from the building regulation system, which has not been functioning well for some time. It falls to me, and to the Secretary of State, to play our part in correcting that, and we are trying to do so with all speed.
