My Lords, this amendment and the previous debates concern ensuring that the homes that we want deliver sustainable drainage, with the benefit of protecting home owners from floods and wider amenity benefits to communities and to biodiversity. I am disappointed that the Government and the Commons did not feel able to accept amendments that this House voted for to end the automatic right to connect for housebuilders. However, I thank the Minister for what is being proposed now in terms of a concession on the review, which we believe will demonstrate all too clearly that the evidence on the ground that we have heard about in this Chamber on numerous occasions shows that SuDS are not being delivered.
However, the amendment we propose is to ensure that the review will be thorough. First, it would ensure that the review looks not just at policy but at actual developments; and that there is a robust sample size, taking into account the proportion of new developments and the type of SuDS being implemented. Secondly, it would ensure that the review is timely. The Climate Change Committee will report to Parliament next June. I am sure that the noble Lord, Lord Krebs, will want to say more about this. It will consider the penetration of sustainable urban drainage. It is therefore vital that any review undertaken can report so that the adaptation sub-committee has that information, can assess it and provide appropriate advice to Parliament by the time the report is published in June.
I hope that the Minister, in summing up, will be able to reassure the House that the review will indeed be thorough; that she will reassure the House that the Government accept the strength of feeling on this issue that the House has demonstrated on numerous occasions; and that we will be able to deliver the sustainable urban drainage systems that we all want to see. I beg to move.
