My Lords, I welcome both these amendments; indeed, they are very similar to amendments I tabled in Committee. I am grateful to both the noble Lord and the right reverend Prelate for pushing these further to see what response we get from my noble friend the Minister.
I will try not to repeat everything that I said in Committee. On the minimum number of houses to which this would relate, the Bill takes everything the wrong way. It is absolutely clear that smaller builders—whom this clause does not target very effectively, as the noble Lord, Lord McKenzie, said—are more capable of building better-quality homes than the large builders. They are in no way constrained by technology. The clause somehow conveys a government view that small-scale builders are merely jobbing builders with no skills. That is absolutely wrong and sends completely the wrong message. They can deliver a high standard of homes as well as any other building business.
I agree with the right reverend Prelate. I certainly live in a very rural area. A number of the developments there are small scale, and they are all off the grid. I am off the grid. Local developments in villages around me are off the grid. We therefore have the problem that we institutionalise for another 50 to 100 years, or whatever the life expectancy of the property is, potential fuel poverty for those who live in those houses—that or we have an expensive retrofitting programme in the future, which we are already struggling trying to make work. In fact, DECC’s own figure for the cost of retrofitting the current housing stock to get it up to a proper level is £60 billion. That is quite a big sum. We should not be starting to add to that figure.
I welcome the proposal to keep a minimum number of houses; I suggested five in Committee, but 10 is quite reasonable. I welcome that fact that my noble friend the Minister, judging by our conversations, does not see the figure being any greater than that. Clearly, we are having a consultation process at the moment and I am sure that he cannot be specific until that is closed, but I welcome the fact that the Government have recognised that that number cannot be too large. We certainly need a sunset to this clause. I hope that that will come out of this as well.
My noble friend Lady Maddock has gone through the questions surrounding the standards for zero-carbon homes very well, and how that issue appears to have moved backwards and forwards and backwards. I look forward to enlightenment in that area. I again come down to what the right reverend Prelate said about allowable solutions. I am not at all against them
in concept, but wherever possible the targets need to be met within the building itself or very close to it. Once again, if we do not do that, the people who live in those houses will have increased energy bills for as long as they live there. We might neutralise carbon emissions globally—ensuring that is much more difficult on allowable solutions than actually on the property itself—but then you still have the problem that that property requires more energy to heat it and to keep it to the right standards.

I welcome these amendments and fully accept that, if we have a small development exemption, that could well be in secondary legislation rather than in the Bill. That is unfortunate so I look forward to the Minister’s explanation on it, but I recognise his good will and wish to get this consultation out and completed. I am pleased that we are still pursuing zero-carbon homes. It might not be at the pace that some of us would hope for, but it is still a government objective and priority that we wish to achieve. I would have liked to have reached a slighter higher level of achievement but at least we are making some progress on this.
