My Lords, I probably will not detain the Grand Committee for too long on this amendment, as in a way the principle has already been discussed on the amendment tabled by the noble Lord, Lord McKenzie. From our debates so far, we realise that the regulations really are not about zero-carbon homes; they are an approximation to that and we can never get to it. However, a great deal of consultation has gone on over the years with the building industry. We are always told—I accept it entirely—that one of the things that we need to do is make changes in regulations predictable and signal them far ahead, so that there is a degree of certainty and the producers can prepare and everything runs smoothly for the industry. With the Government and the industry, the Zero Carbon Hub spent great time coming to standards that would be accepted for 2016, and I admit to disappointment that we have not really got there at present. We have also removed a requirement about appliances within those homes being taken into consideration.
I talked about hope value in terms of planning just now, and my hope value in terms of the Bill is that the Government might reconsider where they go in this area, as we are still far away from zero carbon. I fully
accept that we have to be practical, but this is the trajectory that we were expecting, it was negotiated with a large proportion of the industry, and it would be a good model were we able to pursue it. I beg to move.
