My Lords, I will try to do a little better than last time, when I completely ignored my noble friend Lord Shipley. I apologise to him.
I very much hope that the Minister will be able to dismiss this amendment with the same dispatch as he did on my previous amendment because it seeks to achieve that for each building there can be only one regulatory authority and there is no circumstance where a higher-risk building has another regulator at work—another person supervising and signing off completions. There seem to me to be two situations in which, as I understand it, the Bill is not absolutely decisive on that point, as set out in Amendments 5 and 10.
The first relates to a situation where comparatively minor works may be carried out in a higher-risk building which do not, of themselves, directly affect fire resilience. It would therefore seem quite possible for that application to be under the regulatory eye of somebody other than the building safety regulator. That might be a private regulator or a local authority building control body. There are circumstances, and we could examine them in more depth if we need to. The second is that there are currently a number of trades and businesses which are self-certified: electrical works and heating works are self-certified, as are drainage and plumbing works, to a significant degree, and rewiring, internet and IT networks are in the same situation. Those self-certified cases, including, incidentally, replacing windows and so on, may result in the piercing of firewalls, the cutting through of cavity barriers or a loss of airtightness. Of course, a loss of airtightness means a loss of smoke-tightness, which can be vital in a fire situation.
What I want to hear from the Minister is that this loophole—or area of concern—that I have briefly outlined to the Committee is in fact covered by yet another clause somewhere in the Bill that deals with the issue completely. I hope that the Minister can give us a very quick, simple and straightforward reply. It will all be worked out for him on his piece of paper, and I look forward to hearing that, but if it is not forthcoming, we will of course want to return to this later because it is of central importance that we do not have divided authority or, indeed, work sneaking through, if you like, under self-certification, which inadvertently contributes to a diminution of the safety of that building.
There are plenty of practical examples at the moment. The reports I have had from the Greater Manchester Fire and Rescue Service about fires in what used to be my constituency say that many residential fires of this sort are triggered by tradespeople who cause fires by their activities when they are carrying things out. Very often, they are the people who have cut through the cavity walls and the fire compartmentation, thus contributing to the damage that happens. This is not a hypothetical situation, and it is an important matter, which I hope the Minister will be able to satisfy us is covered by the drafting of the Bill. I beg to move.
