I agree 100%. It is important to think about the mental health impact as well as the physical impact.
Hannah Bardell (Livingston) (SNP)
The hon. Lady may not know this, but my staff and I became somewhat expert on this matter in 2015 when there was a flightpath consultation by Edinburgh airport. My Livingston constituency has, I believe—although it may be debated—around 70% of Edinburgh’s flight traffic during the day, but also at night. What we learned from that experience was that there was a complete lack of community consultation. Would she include in her asks of the Government that community consultation, compensation, proper structures and oversight of that must be implemented? You would not put a road through somebody’s constituency without proper consultation. Why would you put a flightpath over people’s homes without consulting them properly?
Sarah Olney
That point is powerfully made. The Government set the current night flight regime at Heathrow airport, but the restrictions are simply not stringent enough and the true number of night flights is significantly higher than the quota allows. An average of 16 flights per night are permitted to land at Heathrow each year between the hours of 11.30 pm and 6 am, but flights may receive special dispensation not to be counted towards the overall quota if they are delayed due to specific reasons such as weather conditions or air traffic control disruption.
From July to September this year, 231 flights were granted dispensation. That is between two and three additional flights per night on average. In total, 475 unscheduled night flights arrived at or departed from Heathrow airport due to extreme delays and disruption. At times, my constituents would suffer almost continuous noise from aircraft overhead. That is partly due to the Government’s complete lack of long-term planning, which saw airports engulfed in chaos and flight schedules thrown into the air. However, it also proves that the current restrictions are insufficient to limit the impact on residents when disturbances to flight patterns occur.
Sarah Olney
I thank the right hon. Gentleman for that intervention; he is absolutely right. The Government state that their policy is to
“limit and, where possible, reduce the number of people in the UK significantly affected by aircraft noise.”
We can see from the numbers already that the policy is not fit for purpose, but he is correct that it is not about the numbers, but about the impact on those who are affected.
Long-term exposure to nocturnal aircraft noise is strongly linked to sleep disorders, and lack of sleep or disrupted sleep can have a direct impact on people’s health. One study found that, for each additional 10 dB of night-time aircraft noise that communities are exposed to, there is an increase of between 14% and 69% in their risk of high blood pressure, increasing the risk of strokes and heart attacks.
A World Health Organisation study from 2009 also found that an individual may suffer from negative health impacts of sleep disruption even if they do not wake up at night. Other researchers have found links between long-term exposure to aircraft noise and an increased risk of obesity, depression and cardiovascular issues—and I do not need to cite a scientific study to explain the impact that a lack of sleep has on mental wellbeing, as so many right hon. and hon. Members have already mentioned it.
Sarah Olney
Does the hon. Lady mind if I make a bit more progress?
In children, sleep disruption makes it more difficult for them to retain focus throughout the day. Studies have suggested that that has a negative impact on reading comprehension and memory, which can have a knock-on impact on their academic performance and general wellbeing. The human impact of night flights only intensified over the summer months, during which temperatures reached record highs. Many Londoners were left choosing between keeping their windows shut and suffering with unbearable heat or opening them and hearing the full roar of jet engines overhead. This opposition to night flights does not arise purely out of annoyance or inconvenience.
Sarah Olney
I thank my hon. Friend for that comment. She is precisely right. Our concern relates not only to night flights, but very much to the fact that Heathrow expansion would lead to increased noise levels and around 6 million additional tonnes of carbon being pumped into the atmosphere each year. The UK cannot properly tackle the climate crisis if we continue to expand our airports, especially when we should be promoting greener transport.
Hannah Bardell
I promise this is my last intervention. On the point of greener transport, does the hon. Member agree that freight flights, which are particularly noisy and polluting, should especially be banned at night? We discovered in studies and the work we did in my constituency that they were the noisiest and most problematic. We are all compelled to look for alternatives, as is the aircraft industry.
Sarah Olney
The hon. Member is particularly right on that. Where particular types of flight are known to be noisier, there should be additional restrictions. Members listening to the scale of disruption caused by night flights might wonder why they are still allowed to continue, and that is precisely the question to which I am seeking an answer.
Heathrow bosses have argued that night flights are vital to the UK economy, but there is a serious lack of evidence to back that up. The Heathrow Association for the Control of Aircraft Noise and other campaigners’ groups have argued that the economic benefit of night flights is exaggerated. Heathrow claims that the direct benefit of night flights operating at Heathrow was £325 million in 2011, supporting 6,300 jobs, but its estimates are based on a report that expands the definition of jobs supported by night flights significantly and includes the many day workers who clock in before 6 am.
The positive economic benefits of night flights are not certain. Researchers at CE Delft found that a ban on night flights would only harm the national economy if none of the passengers who currently arrive on scheduled flights before 6 am were transferred to other flights. There is simply not enough data at present to claim that night flying is essential to the UK economy. The studies we have are more than 10 years old and have not taken into account the changes to the aviation sector since the pandemic.
London is one of the most overflown capital cities in the world. Millions of people across the city experience the negative impacts of night flights, such as on their health, sleep quality and mental wellbeing. What my constituents really need is a complete ban on flights between the hours of 11 pm and 6 am. That is the only way to prevent continued disturbance. Despite the vast amount of disruption caused by night flights, no independent analysis has ever been conducted to show the impact of night flights on London’s health, economy or society. If the Government refuse to legislate to ban night flights, they must at least look at tightening the current restrictions, to limit the human impact on local communities.
For the Government to make an informed decision, we need accurate, independent data on the negative impacts that these flights have on the surrounding communities, as well as the supposed economic benefits. Will the Government commit to commissioning a full independent analysis on the impact of night flights? The Department for Transport must listen to the concerns of local communities and take those into account to devise a night flights policy that works for both residents and the aviation sector.
I would like to take a moment to thank the Members who attended the debate and have added so much emphasis to what I wanted to say.
