My Lords, just to say to the noble Lord, Lord Kennedy, I will chase my noble friend. I think he might have gone to get the letter, actually.
It is helpful that the noble Baroness, Lady Parminter, has revised the carbon compliance standard in her new amendment, but we still do not know the risks it may pose to the viability of home building in some parts of the country, or the impact it may have on the home building industry, particularly some small builders. We need a clear understanding of what is technically possible, viable and cost effective to make any changes to energy performance standards for new homes. That is why we are introducing a statutory duty on this Government to undertake a full and comprehensive review of energy standards based on cost effectiveness and the impact on housing supply. We will report back to this House on the outcome of the review within the next 12 months.
The other place has given its considerable support to this review based on cost effectiveness, and it is supported by the Home Builders Federation—the main trade body that represents home builders of all sizes. The Housing Minister in the other place also pointed out the following yesterday:
“We said in our manifesto that we will meet our climate change commitments and that we will do so by cutting emissions ‘as cost-effectively as possible’. The electorate voted for that and the review will help to ensure that we can deliver it”.—[Official Report, Commons, 9/5/16; col. 463.]
So before the other place considers any changes to energy performance standards, home builders and the electorate think that we first need to have an understanding of what is cost effective. Is it right that we should go against their views?
Finally, I remind the House that it is not prudent to set requirements such as this in primary legislation. If, in the light of consultation, any slight adjustment to requirements were needed, we would not be able to do so without further primary legislation. Therefore, I ask the noble Baroness, Lady Parminter, to withdraw her amendment.
