Planning and Infrastructure Bill

Lord Blencathra Excerpts

Report stage
Wednesday 29th October 2025 Lords Chamber

[Baroness Grender (LD)]

I will speak briefly to this group. I applaud the noble Baroness, Lady McIntosh, for her resilience in the face of some opposition from her own Benches.

Amendment 197 seeks to end the automatic right for developers to connect surface water from new homes to the public sewerage system, regardless of capacity, and would instead provide a framework for the approval and adoption of sustainable drainage systems.

Amendment 198, also in the name of the noble Baroness, Lady McIntosh, would go further by linking the right to connect to compliance with the Government’s newly introduced national standards for sustainable drainage systems, creating a stronger incentive for developers to follow this guidance, in advance of full implementation of Schedule 3 to the Flood and Water Management Act 2010.

I believe that some of this was developed by the All-Party Group on Flooding and Flooded Communities, among others, and we certainly support what the noble Baroness is attempting to do with these amendments. Managing surface water is a huge challenge. It is such an irony that we have the problem of lots of surface water, but we also do not have enough water.

Protecting water quality, supporting biodiversity and reducing flood risk are really important priorities. We see the merits of these amendments. While they are not the only steps needed to achieve a fully resilient water system, they represent a constructive approach to improving drainage management in particular, and to encouraging developers to take responsibility for sustainable practices.

[Lord Blencathra (Con)]

My Lords, I thank my noble friend for tabling her amendments in this group. I know that the whole House respects her for her commitment to the issue of sustainable drainage, and I pay tribute to her for her persistence in raising this particular matter, because it is about time that we made some progress on it.

Our water system is put under pressure when developments are built out and connected up, and my noble friend is right to raise this. Can the Minister please take this opportunity to set out the Government’s ongoing work on delivering a sustainable future for our water systems? We would also be interested to hear what active steps the department is taking to engage with the development sector, including small and medium-sized developers, to ensure that existing non-statutory standards for sustainable drainage have been implemented.

My noble friends have mentioned 2010. I can beat that. I think it was in 1992 that, as Environment Minister, I was shown a revolutionary new system whereby the downpipes from our houses are connected to a soakaway and a system of seepage pipes about a foot underground, where the water then slowly leaked back into the soil. For big commercial car parks, the seepage pipes were put down a metre, so they were not crushed.

Those systems were in development then, and I said, “This is a jolly good idea, we should do it”, but the word was, “Oh no, Minister, it is not quite the right time to do it yet”. So I would be interested to hear what the Minister can say about that particular area. What development work is going on for seepage systems in ordinary domestic houses? We have millions of gallons of pure raindrops falling on our roofs, we put it into the sewerage system and then the water companies spend millions of pounds taking out the clean water again. Seepage systems must be the way to go in the near future.

[Baroness Taylor of Stevenage (Lab)]

My Lords, I thank the noble Baroness, Lady McIntosh of Pickering, for proposing these amendments, and for her persistence in these matters. I remember having long discussions with her on the same subject over the course of the Levelling-up and Regeneration Bill.

Proper implementation, adoption and maintenance of sustainable drainage systems can significantly reduce the pressure on sewer networks from new developments by as much as 87%. This creates capacity for further development in areas where conventional drainage alone would be insufficient. There is growing need for SUDS in more developments, with designs that can withstand changing climate conditions, support broader water infrastructure goals and contribute to addressing the water pollution challenges.

Progress has already been made through the planning system to improve SUDS delivery. I am afraid that I do not accept the assertion of the noble Baroness, Lady Coffey, that MHCLG has been holding this up. The updated National Planning Policy Framework, published on 12 December, now requires SUDS for all developments that have drainage implications.

Sewerage companies have the authority to reject connection requests if they believe that the mode of construction or condition of the drain or sewer will prejudice their network or fail to meet reasonable standards. There is no automatic right to connect to the sewer system.

The Independent Water Commission, led by Sir Jon Cunliffe, has reviewed the regulatory framework for the water sector in England and Wales. Both the UK and Welsh Governments are assessing the findings, including any potential impact on the right to connect. Any legislative changes to Section 106 should take into account the findings of the Independent Water Commission’s report before moving forward. The Government remain strongly committed to requiring standardised SUDS in new developments and increasing rainwater management strategies to mitigate flood risks and to adapt to climate change.

In June 2025, the Government released updated non-statutory national standards for SUDS, which have been positively received by stakeholders as a very constructive development. Later this year, the Government plan to consult on national planning policies, including those related to flood risk and SUDS. Additionally, a consultation will be launched on ending freehold estates which will explore ways to reduce the reliance on private management arrangements for community assets, such as SUDS. When we bring those national planning policies forward, I hope that the noble Baroness will take part in the discussions. As she has such a detailed knowledge of the subject, I am sure that she would be very helpful in the preparation of those national planning policies.

For all these reasons, the Government cannot accept Amendments 197 and 198. I hope that the noble Baroness will withdraw Amendment 197.

--- Later in debate ---

[Lord Fuller (Con)]

My Lords, I support Amendment 199 because I think it is important that we protect and recognise our historic trees. I am thinking not just of the highway and byway trees; there are some really special champion oaks in South Norfolk, where I was the leader of the council. We took steps to recognise them, bring them into the local plan and give them special designations. They form the basis of the strategic gaps between settlements, which is not just a good thing for the landscape; it also maintains that spirit of community.

I am thinking in particular of Kett’s oak, which is a champion oak said to be over 500 years old—it might be more—sat there on the B1172 between Norwich and Wymondham. It was the site of Kett’s rebellion, where Robert Kett marched 16,000 people to Mousehold Hill in Norwich, having had a petition of 29 demands. I expect the Government to want to knock this one back, but I note the context of that historical nature, as well as the landscape importance. Some of Kett’s demands were to limit the power of the gentry and to prevent the overuse of communal resources. It did not do him any good—Kett was executed on 7 December 1549 —but it is part of the lexicon. I am conscious that my noble friend Lady McIntosh is going to take me outside and duff me up afterwards. I hope I do not suffer the same fate as befell Robert Kett.

My serious point is that having a national register of important trees is not just important for biodiversity and all that sort of thing; they are part of our history and culture, and these are things to be celebrated. I warmly endorse and support Amendment 199, with my personal knowledge of Kett’s oak, and other noble Lords will have similar stories from their own areas. I suppose the salutary lesson is that when that Sycamore Gap tree was felled, quite terribly, in Northumberland last year, there was a national outpouring. Amendment 199 attempts to capture that sense of pride and purpose, and it has my full support.

[Lord Blencathra (Con)]

My Lords, we all share an appreciation of our heritage trees. The Fortingall yew in Perthshire is estimated to be around 2,300 years old, and there are oaks on the Blenheim estate that are estimated to be over 1,000 years old. Of course, the iconic Sycamore Gap tree, which I was driven past the day before it was cut down, was over 100 years old, but while it was a relatively young tree by comparison, I think it was probably the most famous iconic tree we had, loved by millions.

Whether they be ancient yews or oaks that have stood in Britain for hundreds if not thousands of years, our heritage trees are a link to our past. That is why we have robust tree protection laws. While we are committed to maintaining those protections, will the Minister please confirm that the existing protections for trees will not be swept away inappropriately without due consideration when developments are considered? It would be unacceptable to have an EDP that meets the overall improvement test but necessitates cutting down one or more heritage trees. I think we all agree that that would be unacceptable. Will the Minister please set out the Government’s view on the current penalties for breaches of tree protection orders? Do the Government feel that these remain appropriate, or do Ministers have plans to review them or introduce new regulations and new laws?
