My Lords, the noble Earl, Lord Lytton, made a compelling argument for a general extension of improvement relief, as did the noble Baronesses, Lady Pinnock and Lady Hayman, for extending heat network relief. For me, this is all about joining the dots across the legislation, so that we have a coherent picture. As the Minister said, we already have a permanent exemption for renewable energy and storage. All these factors feed into our overall strategic targets, so we need a coherent picture across the legislation. The Minister rightly talked about fiscal responsibility and the need to bear it in mind.
The other side of the picture, to counter that, are all the benefits to increasing private investment—in the case of energy efficiency, lower bills—and the benefits from overall economic growth that would flow from that. I look forward to further discussions with the Minister leading up to Report, but for now I beg leave to withdraw my amendment.
