Planning and Infrastructure Bill

Baroness McIntosh of Pickering Excerpts

Committee stage
Wednesday 17th September 2025 Lords Chamber

[Baroness McIntosh of Pickering]

337: After Clause 87, insert the following new Clause—
“Sustainable drainageThe Secretary of State must bring into force in England all uncommenced parts of Schedule 3 of the Water Management Act 2010 (sustainable drainage) within three months of the day on which this Act is passed.”Member’s explanatory statement
In England, developers have the automatic right to connect surface water arising from new homes to the public sewerage system, irrespective of whether there is capacity for this. Implementation of Schedule 3 of the Flood and Water Management Act (2010) would end this automatic right to connect and provide a framework for the approval and adoption of Sustainable Drainage Systems (SuDS), paving the way for their widespread use.

[Baroness McIntosh of Pickering (Con)]

My Lords, I am delighted to have reached this small but perfectly formed group of amendments in my name. I take the opportunity to thank for their support the noble Baronesses, Lady Young of Old Scone, Lady Jones of Moulsecoomb—I wish her a speedy recovery for her toe—and Lady Willis of Summertown. I am very grateful to them all.

If I could declare my interests, I am co-chairman of the All-Party Parliamentary Group for Water and an officer of the All-Party Parliamentary Group on Flooding and Flooded Communities. I have co-authored a number of Bricks & Water reports with the Westminster Sustainable Business Forum, and I am very grateful for its support on that.

I will initially set out the contents of the amendments and then explain why I think the Government should support them or come forward with their own amendments in lieu on Report. Turning first to Amendment 337, as the Explanatory Notes make clear, developers currently have an automatic right to connect surface water arising from new homes to the public sewerage system, irrespective of whether there is capacity for it or not. Implementation of Schedule 3 to the Flood and Water Management Act 2010 would end that automatic right to connect and provide a framework for the approval and adoption of sustainable drainage systems, paving the way for their widespread use.

[Baroness Taylor of Stevenage (Lab)]

My Lords, I thank the noble Baroness, Lady McIntosh, for tabling these amendments and for her thorough introduction. I meant the other day to ask the noble Baroness, Lady Bennett, to take our very good wishes for a speedy recovery to the noble Baroness, Lady Jones, who I hope is recovering quickly. I am sorry that I did not do that before.

Effective implementation of SUDS, including adoption and maintenance, can reduce the impact of new developments on sewers by adding up to 87%, creating headroom for additional developments where they may not be possible with only conventional drainage. I have previously shared with the noble Baroness, Lady McIntosh, some of the outstanding schemes that I have seen in Sussex and with the noble Lord, Lord Lansley, in Cambridge. The responsible developers make provision for the ongoing maintenance of these schemes. We need to see sustainable drainage in more developments, to designs that cope with changing climatic conditions, deliver wider water infrastructure benefits and help to tackle our water pollution problems. We have already taken steps to improve the delivery of SUDS through the planning system. The update to the NPPF, published on 12 December, expanded the requirement to provide SUDS to all development with drainage implications. I restate that, although the NPPF is not a statutory document in itself, it is part of the statutory planning system.

Sewerage undertakers have the ability to refuse a connection where it appears to them that it would prejudice their network or not meet their reasonable standards. There is no automatic right to connect to a sewerage system. The Independent Water Commission, chaired by Sir Jon Cunliffe, is reviewing the water sector regulatory system in England and Wales. The UK and Welsh Governments will consider the report, including whether it has implications for the right to connect. That report should be factored in before considering any potential legislative changes to Section 106. Regardless, the Government are strongly committed to requiring standardised sustainable drainage systems, or SUDS, in new developments and are considering how best to implement our ambitions.

The Government published updated non-statutory national standards for SUDS in June 2025, which were welcomed by stakeholders as a positive step. We intend to consult on the national planning policy related to decision-making later this year, including policies on flood risk and SUDS. I will take back the noble Baroness’s point about run-off, because it would be useful to consider that at the same time. Also this year, we will consult on ending freehold estates, which will include options to reduce the prevalence of private management arrangements for community assets including SUDS. For this reason, I hope that the noble Baroness will withdraw her amendment.

[Baroness McIntosh of Pickering (Con)]

I am grateful to all who have spoken and those who have supported the amendment: the noble Baroness, Lady Young, who echoed my concerns about why the original legislation was not implemented; the noble Baroness, Lady Bennett, for reminding the House about the “slow the flow” scheme, particularly the Pickering pilot scheme that I was closely associated with; and my noble friend Lady Coffey for pointing out the reason for the blockage and delay. It is like, “We are going to do it, but just not yet”. There is a degree of urgency and let us bear in mind that, as my noble friend Lord Blencathra on the Front Bench pointed out, if your house was built on a flood plain since 2009, you cannot be insured, or the only insurance that you can get is probably so cripplingly expensive that you cannot afford it.

For a host of reasons, I believe that the time is now. I was told during the passage of the levelling-up Act that we would have to wait for a different opportunity. The time is now, so I will revert to this at a future stage of the Bill. For the moment, I beg leave to withdraw the amendment.

Amendment 337 withdrawn.
