I am happy to go on to talk about SuDS, but I wanted to address why there is a collective self-interest in everybody getting involved in this, because it will help to reduce pollution. That is why it was a key part of the White Paper. Speaking personally, as someone who loves nature, this is also an opportunity to increase nature in different areas. These pre-pipe solutions do not have to be concrete tanks; they can be somewhere that is quite beautiful. We want to maximise the opportunities offered by better managing rain and looking at where it lands. It is estimated that the average household roof collects 85,000 litres of rainwater every year—obviously a little more in your constituency, Mrs Barker, and a fair bit in Hull as well, but a little less elsewhere—which is equivalent to an estimated 4 trillion litres annually across the UK, or 1.6 million Olympic-sized swimming pools. We are therefore thinking about not just SuDS or pre-pipe solutions, but rainwater management. There are many different things we can do. That is why we want to work together with other stakeholders including water companies, environmental groups, local authorities and developers to come up with how we can collectively achieve this ambition. On sustainable drainage, it is quite right to point out that the 2010 Act was never fully enacted by the coalition or the Conservative Government. SuDS are vitally important for sustainable development. They help to reduce additional pressure on the sewage system by up to 87%. I am a huge fan, and have spoken quite often about my love for sustainable urban drainage. They can also enable growth: a SuDS retrofit programme in London created the additional headroom for 116,000 new homes. Since we came into Government, our record on SuDS is that in December 2024, we made changes to the national planning policy framework to support increased delivery of SuDS, so that it now requires all developments to utilise SuDS where they could have drainage impacts, and requires those systems to be appropriate to the nature and scale of the development. In June 2025, the Government introduced new national standards, making it clear that SuDS should be designed to cope with changing climate conditions, because whenever we do anything now in this country, we need to have our minds on how our climate is changing, and make sure that we are resilient for the future. SuDS should also deliver wider water infrastructure benefits in the form of flood prevention, storm overflow reduction and reuse opportunities—but of course there is more that we need to do. As I say, some time has passed since the 2010 Act was enacted, and it is important that we consider the most efficient and effective way of securing its objectives. We currently think that that could be through changes to planning policy and adoption and maintenance, which I will come on to, rather than commencing schedule 3. With that in mind, we have been tightening national planning policy on this important issue. We are consulting on a new national planning policy framework at present, which adds the requirement that sustainable drainage systems are designed in accordance with the new national standards, to provide a consistent basis for their design and implementation. Additionally, we are consulting on legislative and policy options to reduce the prevalence of unadopted estates and the injustices associated with them, including for SuDS. On 18 December last year the Government published two consultations, one on enhanced consumer protections for homeowners on privately managed estates and another on reducing the prevalence of estate management arrangements. We continue to collaborate with industry leaders and, since data has been mentioned, I note that we are supporting the development of a new rainwater management platform, which will provide digital tools to support the delivery of high-quality SuDS. We are working with the industry body CIRIA—the Construction Industry Research and Information Association—to better understand the challenges around property-level SuDS and rainwater harvesting. Subsequent guidance will support industry to deliver in line with our recently published national standards for SuDS and will be publicly available. To ensure the longevity and proper maintenance of SuDS, we are scoping options for maintenance funding mechanisms and the methodology for calculating maintenance costs. We will publish guidance later this year, which will support the delivery of SuDS in line with the new national standards. I will answer some of the questions on maintenance. We recognise the challenges relating to the adoption and maintenance of SuDS and how that can impact communities, so we are committed to ensuring they are well maintained. As I mentioned, we issued standards in June ’25, and in support of those we are currently conducting research into the funding of SuDS maintenance. We are looking with industry and experts at different funding mechanisms as well as the methodology for calculating maintenance costs. To ensure that SuDS are provided and maintained as part of a new development, section 106 agreements can be used to provide for the maintenance of SuDS over their lifetime, where the statutory test is met. We are consulting on a new national planning policy framework to require SuDS to be designed in accordance with the new national standards, and a consultation that sets out that SuDS should have maintenance arrangements in place to ensure an acceptable standard of operation for the anticipated lifetime of the development—that is really important; it is not just about when it is built, but the lifetime of the development—building on the current requirement for those to be in place for major development proposals. The consultation is open until 10 March. I encourage Members and anyone interested to respond to that consultation. There has been mention of specialists and making sure that we have the people we need. We need skilled planners, including specialists in areas such as ecology and infrastructure—they are essential to making sure we have proactive planning services. We know that local planning authorities continue to face challenges in recruiting and retaining staff. Ultimately, it is up to local authorities who they employ and how they do so. Nevertheless, given how widespread those pressures are, the Government are significantly expanding support through the planning capacity and capability programme, including growing the graduate and mid-career pipeline, strengthening specialist training through the Planning Advisory Service and launching a new planning careers hub to open additional routes into the profession. We are trying to grow our own planners for the future, and looking at whether an increase to local authority funding for SuDS could be required. I hope all that helps to illustrate that this Government have not waited 14 years to deliver what the previous Government were attempting; we are getting on and delivering it now—from changes to the planning framework to ensuring that we have the talent we need, innovation, and working with others to find new ways to deliver the protection that our country needs. We are strongly committed to improving the implementation of SuDS; the actions I have outlined today are just the beginning and I look forward to working with all hon. Members in this room towards that goal.
