The Parliamentary Under-Secretary of State for Transport (Mike Kane)
I congratulate the hon. Member for Richmond Park (Sarah Olney) on securing this debate about the impact of aircraft noise on local communities, and I thank her for her speech. Aviation noise presents a sensitive issue. I grew up under the flight path to Manchester airport, and I remember the BAC one-elevens, the Tridents and Concorde. As a school child I saw the space shuttle do a low pass on a jumbo jet, which inspired me for the rest of my life. Thank God we do not have those planes any more, given the smell that they emitted. However, we need to strike a fair balance between the impact of aviation on the local environment and communities, and the economic benefits that flights bring. That is the challenge for aviation noise policy.
The hon. Lady spoke passionately about the impact of aviation on noise levels, and I recognise that noise from aircraft, particularly at night, impacts on the local community and, as she said, can impact on people’s physical and mental wellbeing. Major airports with more than 50,000 movements per year are obliged under the Environmental Noise (England) Regulations 2006 to produce noise action plans. Noise action plans act as a driver for aircraft noise management and for the mitigation that is required around airports. I am pleased to report that all major airports within scope of the regulations have now produced their noise action plans for 2024 to 2028. With the exception of the noise action plan for Manchester airport in my constituency, which was submitted later, I can confirm that those noise action plans have now been adopted by the Department for Environment, Food and Rural Affairs.
The Heathrow airport noise action plan has been published, following consultation with local stakeholders, as the hon. Lady rightly said. It is supplemented by a commitment to commission and support research, and a focus on improving the way that the airport communicates and engages with local communities. Heathrow sees that last element as pivotal in helping it to understand and address key priorities for local people. Heathrow also has a sustainability plan that covers a wide range of issues related to noise management. The airport has set a clear objective to reduce by 2030 the number of people who are sleep-disturbed and highly annoyed, compared with its baseline of 2019. The airport has been working to develop, test and finalise a new package of noise insulation, vortex protection and home relocation support, known as the quieter neighbourhood support scheme. Heathrow’s residential insulation scheme covers 100% of insulation costs up to £34,000 for homes most affected by noise.
Sarah Olney
I am grateful to the Minister for highlighting the various packages that are available for people affected by noise. As he will appreciate, a number of my constituents are in that position, yet many are finding that some of those packages are insufficient and difficult to access. Will he meet me to discuss some of those individual cases?
Mike Kane
I am happy to meet all individual Members who want to improve the quality of people’s lives around our ports and airports.
Heathrow uses a differential charging structure for aircraft operating at the airport. The structure encourages the use of best-in-class aircraft, imposing higher charges for noisier aircraft and lower charges for quieter ones. Heathrow encourages the use of quieter planes by adjusting the differential in night and post-midnight charges for unscheduled operations, with the aim of reducing those operations after 11.30 pm.
The Government, too, are committed to research into aviation noise, and two studies are under way. One study that has been commissioned is on the effects of aviation noise on sleep disturbance and annoyance and how they vary at different times at night. The study is a collaboration between St George’s University London, the National Centre for Social Research, Noise Consultants Ltd and the University of Pennsylvania, and is the first study of aviation noise effects on sleep disturbance in the UK for 30 years. The first stage of the aviation night noise effects—“Annie”—study involved a cross-sectional survey of 4,000 people who live near eight UK airports to assess the association between aircraft noise exposure at night and subjective assessments of sleep quality and annoyance. That stage of the study is currently going through peer review, and we expect to publish it next year. The second stage involves an observational study of individuals recruited from the survey to assess the association between aircraft noise exposure and objective sleep quality. That involves assessments of sleep disturbance and sound level measurements in participants’ bedrooms. That stage of the study is currently in the field.
Taken together, these pieces of evidence will be used to inform future policies for managing night-time aviation noise exposure and to assist with the management and mitigation of health impacts on local communities. They will also support any wider assessment of the costs and benefits of night flying. Our priority remains to deliver a high-quality, robust evidence base, and we are taking all the necessary steps to deliver that. We are now working on the basis that we will publish the full evidence base from the “Annie” study in autumn 2026.
Sarah Olney
I am grateful to the Minister for giving way again. I am pleased to hear that there will be a proper study of the impact of aviation noise on sleep disruption, and I very much look forward to that publication. He may have missed the early part of my speech, where I asked for a much more robust study of the economic benefits of night flights. Will he comment further on that?
Mike Kane
I will come to that, and I look forward to meeting the hon. Member, because I would like to have a safe cycle ride around Richmond Park one of these days. I will be raising that with the constituency MP, and I think it could help with climate mitigation and climate change. I look forward to her views on that.
As I have acknowledged, noise from aircraft, particularly at night, impacts on local communities. At the same time, night flights are also a vital part of global aviation and provide significant economic benefit, not just to the capital city but, as we know, to the whole of the UK. The whole UK relies on Heathrow as our only hub airport to keep the flow of people, goods and services moving, supporting thousands of jobs as a result. With that in mind, for several decades the Government have set out noise controls, including restrictions on night operations at Heathrow, Gatwick and Stansted.
The House can imagine my surprise, on becoming the new Minister, to realise that I had direct powers over the south-east three, and no powers over the rest of the nation. That will hopefully change in the years to come. Those airports are designated for noise purposes under the Civil Aviation Act 1982. That control reflects the need to balance the impacts on communities with the benefits to the UK economy. We also know that Heathrow is one of our major hub airports for cargo and freight to keep this country fuelled, supplied and fed. At other airports, the noise controls are set by local ordinance and local competent planning authorities.
The current night-flight regime limits the number of flights for the purpose of noise management. The night-flight restrictions significantly reduce the number of flights that could otherwise operate within the night quota period between 11.30 pm and 6 am. Earlier this year, the Department for Transport consulted on proposals for the next night-flight regime at Heathrow, Gatwick and Stansted airports, which will commence in October 2025, a year or so from now. The consultation proposes that movements and quota limits for Heathrow, Gatwick and Stansted would remain the same as now for a three-year period covering October 2025 to October 2028. That is while we await evidence that could support change in the future. I thank the hon. Member for Richmond Park for her response to the consultation, and I hope soon to be in a position to announce a decision on the next night-flight regime.
At Heathrow, the number of movements permitted in the night quota period has not changed for many years. During that time, aircraft have become quieter, as I said at the start of the speech, and the overall noise footprint of the airport has shrunk. Progress has been made. At Heathrow, for example, between 2006 and 2019, there was a reduction of 21% in the number of households exposed to aircraft noise within the London 55 dB noise contour area. The noise footprint of new-generation aircrafts, such as the Airbus A350 and the Boeing 737 MAX, is typically 50% smaller on departure and 30% smaller on arrival than the aircraft they are replacing. I talk with manufacturers all the time about the future of flight and how we can carry on reducing the noise footprint of these vehicles. Overall, noise from aircraft movements is expected to continue to fall in the future compared with today’s levels.
I will briefly touch on airspace modernisation, which is a key plank of our manifesto. It is one of our key commitments, along with sustainable aviation fuel. We have an analogue system in our skies in the UK in a digital age. The system was designed closer to the time that Yuri Gagarin went into space than today. A pilot who travelled through time, coming in the TARDIS back to the future, would still be flying the same flight paths that they would recognise from more than 60, 70 or 80 years ago. That has to change if we are to maximise the benefits to aviation and growth and the carbon reduction we could bring, if we just got the flights not to circle over the hon. Member’s constituency, but to fly in a straight line point-to-point.
Munira Wilson
I heard the Minister from a sedentary position call my hon. Friend the Member for Richmond Park (Sarah Olney) a luddite when she made her point about airspace modernisation.
Munira Wilson
Yes, I am afraid so. The Minister is making the point that we need modernisation. I say to him respectfully that I, my hon. Friend and our constituents recognise the need for innovation and to move with technology as it changes. Of course we want to reduce carbon emissions, and we support a better Heathrow—not a bigger Heathrow—as we understand its importance to the economy, but on airspace modernisation we could still achieve some of the benefits by adopting a “do minimum” approach, gaining benefits from modernisation while not coming up with lots of new flight paths and really intensifying noise over certain areas that might not be overflown at the moment. We have seen how in other countries airspace modernisation has led to noise sewers. Will he offer reassurance to the residents of Teddington, Twickenham, the Hamptons and St Margarets that those places will not end up becoming noise sewers? Will he please commit to a “do minimum” approach and transparency on the process?
Mike Kane
Not for a moment did I suggest that the hon. Members would throw their sabots—as in sabotage—into the mill to grind it up. I do expect co-operation on this. I think that we can make life better for all people, and a rising tide floats all boats. The process will be open and transparent. I have already announced the setting up of the UK airspace design service, which will go out for consultation. I expect Members to be fully involved in shaping its work over the next few years.
As we look to decarbonise our skies and improve them in the ways I just mentioned, there is so much to be gained. We can move on Scottish airspace and northern England airspace. We are already moving on south-west airspace. The south-east will be the hard bit to crack, and that is why the service will focus on that. I hope that we can work together to get that done, hopefully in this Parliament; if not, hopefully early in the next one.
The Government recognise the impact that aviation noise can have on local communities. At the same time, we live in a fully interconnected global world, and the aviation sector has material value for the UK economy. The Government continue to strive for the correct balance between the impacts of aviation on the local community and the economic benefits that flight brings.
Question put and agreed to.
