Flood Resilience

Debate between Calum Miller and Ellie Chowns

Wednesday 28th October 2026 Commons Chamber

[Dr Chowns]

The hon. Member makes an excellent point that I was about to make myself. Natural flood management has got to be a core element of our response to flood risk. I have met families who have gone through the ordeal of seeing their homes flooded time and again.

I have met farmers who have watched valuable topsoil disappear from fields that they have worked for decades. I have met parents whose children cannot get to school because roads have become impassable. I have met business owners wondering how they will cope when the next storm comes. For all of those people, flood resilience is not an abstract issue; it is about whether they can live, work, study and plan with confidence.

[Calum Miller (Bicester and Woodstock) (LD)]

The hon. Lady is making a powerful case. Residents in my constituency have experienced the devastating effects of flooding and live in fear of it happening again. Does she agree that it is extraordinary that when a local flood agency looks into these matters and identifies the steps that can be taken, it does not have the powers to compel other agencies and, in particular, the water companies to take appropriate measures to prevent these things from happening again in future?

[Dr Chowns]

The hon. Gentleman’s point about co-ordination between agencies is absolutely crucial; it is another point that I will be coming to in my speech. This is an issue that crosses boundaries, because river catchments do not respect administrative or sectoral boundaries. We need to have a fully joined-up approach.

Herefordians know what severe flooding looks like. In 2020, Herefordshire experienced the worst flooding in more than 200 years of recorded history. Storm Dennis was absolutely devastating for many families and businesses. Six years on, residents tell me that it is not only the severity of flooding that worries them, but the frequency. The Minister may remember that I raised this issue basically every single month of my first few months in this Chamber because we were facing floods that frequently. Communities that have barely recovered from one flood are increasingly finding themselves preparing for the next. I hope that the Minister will be able to set out today exactly what action the Government are taking to better prevent, prepare for and respond to flooding.

Flooding means different things in different places. In Lyonshall, in my constituency, it means the worry that a new development may not have been built with the infrastructure needed to manage water safely. In Eardisland it means anxiety about whether support will be available when the next flood comes. One issue repeatedly raised with me by residents in Eardisland is the flood recovery framework. Following Storm Bert in late 2024, I attended a public meeting with more than 100 local residents—as ever, the people closest to the problem already knew what needed to be done. After those conversations, I wrote to Ministers to ask whether responsibility for activating the flood recovery framework should rest more with local authorities. From the perspective of someone whose home is flooded, distinctions about national thresholds make very little sense. Local people and local councils understand the impacts better than anyone else.

New Housing: Environmental Standards

Debate between Calum Miller and Ellie Chowns

Thursday 12th September 2024 Westminster Hall

[Ellie Chowns (North Herefordshire) (Green)]

I beg to move,

That this House has considered environmental standards for new housing.

I thank the Minister and all colleagues here for attending. This is the first time I have led a Westminster Hall debate, so please bear with me if I get the procedures wrong. We have lots of time today, so I welcome interventions and hope we can have a useful debate and conversation on this vital topic.

I want to begin by saying that I recognise that there have been some warm words from the Government on this topic. I look forward to hearing more detail from the Minister today. I called for this debate because, although I have heard one or two warm words in the last two and a bit months, I have not heard any detail. In fact, I have been concerned about hearing nothing specific whatsoever in the Secretary of State’s speeches that I have listened to. The Government have made major commitments on building new housing and it is crucial to consider what type of housing, so I wish to start by outlining three reasons why I think this is a really important debate to have.

First, it is absolutely topical. The Government, as we have heard on numerous occasions—indeed, just five minutes ago in the previous debate—have committed to building 1.5 million new houses over the next five years, but what sort of homes will they be? In the Green party we specify that we need to think about the right homes in the right place at the right price. Today I want to talk about what “right homes” means, because it is not just about quantity; it is also about quality and the need to think long term when new homes are built.

The Climate Change Committee did a report on the UK’s housing stock in 2019. It estimated that in 2050 80% of houses in this country will be houses that are already built, so we clearly have a massive job to do when we think about environmental standards and retrofitting the buildings that we already have. However, I am concerned to discuss the 20% of houses that will be new, because the worst possible outcome could be that we build lots and lots of new houses but to poor standards, thus requiring the retrofitting of those houses, too, so let us focus on new build homes.

The second reason why the debate is important is the scale of the issue relating to houses. Our built environment controls or influences roughly half of UK environmental impacts. Domestic housing accounted for more than a quarter of energy use in the UK in the last year for which we have statistics. Heating accounts for the largest single share of emissions from buildings. The fabric of buildings is crucial in controlling the impact of the housing and broader building sector on the natural environment and climate.

Thirdly, this topic is crucial because we have a massive win-win-win opportunity here. This is not just about reducing carbon emissions from housing, which is certainly very important and I will come on to that later. It is also about ensuring that new homes are warm, affordable to heat and not mouldy but great for people to live in. Just this week in the Chamber there was a debate about how people can stay warm in winter. We need to make sure that all new homes are built to the highest possible standards so that we do not have people shivering in their homes and choosing between heating and eating. Of course, this is a fantastic opportunity to give the economy a great big boost, creating thousands of high-skilled jobs. If we get this right, it will be a fantastic opportunity for economic renewal. We know that investing up front is much cheaper than having to retrofit later, so let us do this right from the start.

I wrote to the Minister for Housing and Planning before the recess about the timing of the release of the future homes standard, which has been in the works for quite some time now—we were consulting on it back in 2019-20, and again in 2023-24. In his response to me, the Minister said that the Government will release it in due course. If he is able to do so, I would love the Minister to provide some clarification on the timetable for publication of the standard; it is supposed to start implementation next year, which is only three and a half months away, so time is of the essence. Of course, it is vital that the policy is right, and not just fast, but, as we have had so many years to develop it, I would hope that it could be published ASAP.

This is not a new topic. One of the helpful briefings I read in preparation for this debate, from the House of Commons Library, which I recommend to everyone—it produces fantastic materials—reminded me that in 2006, the then Labour Government said that they would amend the building regulations to require all new homes to have net zero carbon emissions by 2016. Of course, that policy was scrapped by the Conservatives in 2015, but we are now eight years on from the point at which Labour previously thought that all new homes should be net zero carbon. This is the moment for the new Labour Government to fulfil that promise and put in place regulations to ensure that ambition will actually come to pass—better late than never.

I will speak today about five key aspects of environmental standards for new housing: maximising energy efficiency; minimising embodied carbon; maximising on-site energy generation, particularly rooftop solar; maximising biodiversity in the construction of new homes; and maximising resilience against things like flooding and overheating, which will become more and more important as time goes by and climate change becomes a reality that hits us ever harder.

The first aspect is maximising energy efficiency. To meet the Government’s own carbon targets, almost all buildings will need to fully decarbonise. It is not just me who says that—it was in the Government’s heat and buildings strategy back in 2021. That is what the future homes standard was supposed to ensure. However, the version of the future homes standard that is being consulted on is looking at a 75% improvement on 2013 levels by 2030, which is neither good enough nor strong enough. We need to get to all homes being net zero carbon as soon as possible.

I do not expect the Government to introduce measures whereby every single building has to be built to that standard in 2025, but the industry needs a glide path. We need the Government to set that strategy to provide a framework within which the industry can sort out supply chain issues, both in terms of materials and, crucially, through upskilling, so that we are building zero carbon houses, not ones that are just a bit more efficient than the previous ones. The previous Conservative Government were very pleased to talk at length—I wanted to say “to bang on”—about the fact that more houses are reaching EPC C standard than 15 years ago, and that is indeed true. However, virtually no houses are reaching EPC A or B; that figure has increased from 1% to 3% of houses over the past 15 years. Almost no new houses are being built to those really high standards, which is what we need. Of course, there are major problems with energy performance certificates and the standards assessment procedure that underpins them—I am not pretending that that does not need review, and I commend the moves that are being made in that direction. However, we need to recognise that, flawed as it might be as a metric, it is telling us something really quite serious and worrying, which is that housing quality is not increasing at anywhere close to the rate that it needs to.

Key to reducing energy demand is fabric-first design. That needs to be absolutely integral to the future homes standard. It is deeply concerning that the previous Government claimed that the 2021 changes to building regulations were sufficient, and refused to tighten them any further. It is utterly wrong-headed. In making buildings more energy-efficient, fabric-first must be central. I would welcome a commitment from the Minister that fabric-first will be core to the future homes standard.

I also ask the Minister to lift the restriction placed by the previous Government on local authorities setting higher standards for house building in their areas. I do not think that local authorities setting piecemeal higher standards is the way we will get to a decarbonised housing sector, but we should not hold them back from going further and faster while we wait for Government to show the necessary leadership on a national level. We have too much piecemeal policy on this, both between local authorities and between the four nations of the UK. We need to ensure that we are united in a race to the top for standards, not a race to the bottom.

[Calum Miller (Bicester and Woodstock) (LD)]

I thank the hon. Lady for securing this debate and the Minister for being here to respond. I second the hon. Lady’s point about the standards set by local authorities. I represent part of West Oxfordshire district council, where the Salt Cross development was brought forth. It was challenged by the developers because the local authority sought to set forth a net zero standard. The developers were unsuccessful in their appeal, but in a very obliging step, the previous Government issued a written ministerial statement in December 2023 clarifying that no local authority could have the power to set net zero standards. Does the hon. Lady agree that it would be very helpful if the Minister confirmed that this Government intend to issue a new written ministerial statement to make it more possible, until such time as we have new standards, for local authorities to pursue net zero targets in their planning permissions?
