That is significant because, first, all smart meters have “kill switches”—remote switches that can be used to disconnect homes from the national grid—and, secondly, as I said, smart meters routinely transmit a host of data that is of use in aggregate to the development of UK energy markets. I do not in any way wish to promote the Daily Mail view of smart meters as the spy under the stairs—in general, they are not, and their use is well regulated—

On a point of order, Mr Gray. I apologise to the hon. Member for Southampton, Test, but I want to make this point of order before the sitting concludes. We will shortly move on to discuss energy performance certificates and insulation of privately rented properties. In the past, I have been advised that I did not have to register the fact that my wife has a rental property and that her family have rental properties, but I seek your advice, Mr Gray, for the next sitting: will I have to make some sort of declaration before I comment on those areas of the Bill? I wanted to get that in now, so that a ruling can be made for this afternoon.

If the interests are declared in the Register of Members’ Financial Interests and the right hon. Gentleman believes that they are relevant to the debate, it would be prudent for him to call the Committee’s attention to the register. That is not enforced entirely, but the question is whether there might be a perception of bias. Therefore, if the Member has interests that he believes might be of importance, it is probably worth his calling them to the attention of the Committee before he speaks.

Dr Whitehead, will you be concluding in the next 20 seconds?
