New Housing: Environmental Standards

Alex Norris Excerpts

Thursday 12th September 2024 Westminster Hall

[The Parliamentary Under-Secretary of State for Housing, Communities and Local Government (Alex Norris)]

It is pleasure to serve with you in the Chair, Mr Stringer.

I am grateful for the opportunity to close this important debate on environmental standards for new housing on behalf of the Government. I start by adding my congratulations to the hon. Member for North Herefordshire (Ellie Chowns) on securing this debate and on the way she led it. I thought her speech was a real tour de force. I could not really believe that it was the first debate she has led in this place, because she spoke with admirable clarity and power. I have to say that is not how I remember speaking in my first Westminster Hall debate seven years ago. In the spirit of the clarity with which she spoke, I will seek to address the points she raised in turn.

I also want to mention the contribution from the hon. Member for Didcot and Wantage (Olly Glover), with its thoughtful and well-pitched tone about the importance of bringing people with us, so that people see this as a good and positive thing in their life and are partners in the process, rather than net zero being something that happens to them. That is really important for us, as leaders in our own communities, and for the country.

We are mindful of the fact that the homes we build today will shape the environmental landscape for generations to come. The hon. Member for Guildford (Zöe Franklin) talked about not putting burdens on future generations. The choices we make shape the built environment that our children will inherit. It is with that long-term perspective that the Government remain steadfast in the commitment to achieving net zero by 2050. The energy efficiency of our buildings and the standards we set to drive that efficiency are instrumental in realising that goal.

Of course, we are acting in the context of an inherited housing crisis and our banner commitment, made during the election, to build 1.5 million new homes over the course of this Parliament. Again, ensuring that those homes meet the needs of homeowners and contribute positively to the environment is not a luxury: high environmental standards are a necessity. Those two goals must not be seen as being in competition, but rather as mutually supportive, because the decarbonisation of new buildings is a vital part of net zero efforts.

From homes to offices, the UK’s built environment is responsible for about 30% of our greenhouse gas emissions. By improving energy efficiency and moving to cleaner sources of heat, we can reduce those emissions now and in the future and, as the hon. Member for Didcot and Wantage said, create warmer, healthier homes, protecting future generations from the impacts of climate change. But there are very real consequences of rising energy costs in the here and now, and the job of Government is to find the balance between getting those homes built, as the hon. Member for Ruislip, Northwood and Pinner (David Simmonds) said, and doing so in a way that is realisable. In many ways, that is our challenge.

I turn to the five points the hon. Member for North Herefordshire raised. First, with regard to future homes and building standards, we are clear in our commitment to introduce new standards next year that will set homes and buildings on a path away from the use of volatile fossil fuels. Those homes will be future-proofed, with low-carbon heating and high levels of building fabric standards, which I know she is interested in. That will ensure that they do not require retrofitting to become zero carbon as the electricity grid continues to decarbonise, which speaks again to the point made by the hon. Member for Guildford.

The previous Government published a consultation in December, which closed in March. We are a new Government—I hate to say it, but it is true—and have been going for only a little more than two months, so we are looking at that very carefully. In her written question to my hon. Friend the Minister for Housing, Planning and Building Safety and her contribution today, the hon. Member for North Herefordshire stressed the need for a response and was keen to know when it will be. I am afraid I have to tell her that it will be in due course. We are talking to the industry and the public, and we want to ensure the standards we set are ambitious and achievable.

The hon. Lady mentioned local authorities, and I can give her clarity on that point. Plan makers’ powers have not been restricted. The Planning and Energy Act 2008 allows plan makers to set energy efficiency standards at a local level that go beyond national building regulation standards, but that must be done in a way that is consistent with national policy. That is the balance that local decision makers will have to strike, but they have that ability.

The hon. Lady also mentioned the written ministerial statement and said that she wants clarity about its future. I am afraid that it is currently subject to judicial review, and as a result I cannot say very much about it at this time.

I am grateful to the Minister for addressing my comments and those of the hon. Member for North Herefordshire (Ellie Chowns). On local authorities’ powers, will he consider issuing a new written ministerial statement in advance of the new housing standards to clarify the one published on 13 December 2023 by the previous Government, which threw some of the efforts by local authorities to raise standards into disarray?

[Alex Norris]

I am grateful for that question. I cannot make that commitment to the hon. Member today. I hope the assurance I have given has demonstrated that there is a pretty clear landing zone for local authorities, but it must work within national standards. I also make the point, as others have, that the future homes standard consultation has come to a close, and we are consulting on the national planning policy framework. So there are some moving plates in the current setting of standards and we must be mindful of them.

The second point that the hon. Member for North Herefordshire made was about embodied carbon. As we make progress on solar panels, heat pumps and all the other ways to reduce operational carbon emissions, we will see emissions fall in buildings, and therefore embodied carbon will make up proportionally more of a building’s whole-life carbon emissions. We are committed to understanding the scale of the challenge as part of our broader efforts to decarbonise the construction sector. It is vital that we encourage industry to reduce embodied carbon by choosing lower-carbon, but still high-quality, materials. That requires a fundamental shift in design and construction, and that is why we are pushing so hard to encourage the adoption of more efficient design practices that minimise waste, which the hon. Member for Guildford mentioned, and make better use of low-carbon materials such as timber. There are some very exciting new technologies in that space. Where it is safe to do so, higher-carbon materials will be gradually replaced along the way.

The third point that the hon. Member for North Herefordshire made was about solar panels, and this is where we may slightly differ. The Government’s judgment is that we should set targets with regard to performance—what is the energy performance of the new home? Solar panels may well be part of that, but for some buildings they will not be suitable. As a result, if the choice is primarily solar, we miss out on a whole array of innovations that can help those homes reduce their carbon footprint, and there is a risk to cost-effectiveness. As I say, we are goal-oriented, rather than method-oriented.

The hon. Lady mentioned biodiversity net gain. We should recognise and build on the work that the previous Government did in this space. We see this—I think they did too—as a real opportunity as we address our urgent housing needs. We owe it to future generations to ensure that development leaves the natural environment in a measurably better state than it was. That is now mandatory for new applications for developments: all new developments, with limited exceptions, will be required to deliver at least 10% measurable net gain. The hon. Lady spoke about 1.5 million bird and bat boxes, but I would not want to be quite as prescriptive as that. We expect to see net gain, whether through the creation or enhancement of habitats on or off site, or through the purchase of registered biodiversity units on the new open market. We are working very hard with the sector to make sure that it realises those brilliant opportunities.

Let me turn to the hon. Lady’s fifth point, which was on resilience and water. As the Minister for local resilience, among a number of things, that was of particular interest to me. Immediately prior to the debate, I took part in the inaugural meeting of the flood resilience taskforce, which seeks to bring together partners to reduce the number and the impact of floods. I know from having dealt with constituents that having your house flooded is one of the very worst things that can happen to you, short of losing your life or losing a loved one, because you live with the impact of it for so long.

We have a responsibility to make sure that development does not contribute to greater flooding, and the planning system is at the heart of that. We must ensure that development is in areas at the lowest risk of flooding and that it uses sustainable drainage systems to mimic natural systems and to slow the flow of surface waters. The current consultation on proposed reforms to the NPPF is seeking views, and we would be interested to hear from colleagues on that. It is a big opportunity.

The hon. Lady also mentioned water. Safeguarding the water supply is crucial to meeting our climate obligations. As we undertake consultations, we are actively looking at options relating to water efficiency in planning and building regulations. We are developing guidance on water-positive and net zero water developments and on how to integrate water efficiency into energy efficiency and retrofit programmes.

To make a quick point about the NPPF, the planning system is critical to delivering sustainable development that aligns with climate goals. Our NPPF reform marks an important milestone in that journey. Our consultation is seeking views on how planning policy can better support the industry to adapt. We hope to get that feedback, and we will consider any and all contributions.

The Opposition spokesperson, the hon. Member for Ruislip, Northwood and Pinner, made a point about product standards to me for the fourth time in the past 24 hours. I can give him clarity that nothing in that statement from 2 September is about the reduction of standards—far from it. I reiterate the commitment I made yesterday that the Minister for building safety, my hon. Friend the Member for Bethnal Green and Stepney (Rushanara Ali), will write to him with further detail.

While building the homes this country needs to tackle the housing crisis, we will ensure that our climate change commitments are met. We will set high energy-efficiency standards, ensure water efficiency, secure biodiversity net gain and deliver flood-resilient developments as we lay the foundations of a sustainable future. We will ensure that everyone has access to a decent, warm and affordable home. That will be one of the standards by which this Parliament is measured and one of the ways in which our adherence to the manifesto on which we were elected is measured, too. We are actively doing that work. I am grateful to colleagues who want us to go further and faster, and that pressure is welcome. I look forward to working with all colleagues as we go along that journey.
