If I may ask something specific about the Part B guidelines and the issue of smoke toxicity levels in building materials, that was one of several issues that came out of the Grenfell Tower fire. One of the main issues was the smoke toxicity levels in some of the insulation materials. The majority of the insulation materials in Grenfell consisted of polyisocyanurate. A 2019 study showed that 1 kg of that material is enough to fill one normal-sized room with lethal smoke. There was more than 19,000 kg of that material in Grenfell Tower. According to a 2004 Building Research Establishment report in the UK, only two countries in Europe do not have regulations on smoke toxicity levels in their building materials, the UK being one and Ireland being the other. Does Mr Keeley have a view on that in the context of the building regulations and whether they should regulate smoke toxicity levels in building materials that are used?
