Energy Bill

I thank the noble Baroness for giving way. I would like to make an illustration there, which may come on to something later on. She mentions that two houses together should not have different solutions. The big challenge is that both those houses, and probably the rest of the street, are assessed as a whole, and a better solution of the 20 houses has made them the one or two. That is why I have a slight concern about too systematised an approach. I think the noble Lord, Lord O’Neill, made a magnificent case for a degree of that approach; but I think that that point illustrates that, if it is too tram-lined, then we can get into too much trouble, and I understand she is not saying that.
