AEF receives more queries about aviation-related noise pollution than about any other issue. In 2016 we carried out a survey of our members, and noise emerged as the biggest single issue with 83% of respondents reporting noise problems during the day, and 73% reporting noise problems at night. People living under flightpaths from the larger airports, described “excessive”, “unbearable” and “intolerable” noise intrusion from large jets, but it was clear that noise from light aircraft (including small planes, helicopters and microlights) was also a major – and overlapping – concern.
The UK’s aviation regulator, the Civil Aviation
Authority (CAA) states:
“There’s no getting away from the fact that
aviation can be noisy. … The highest levels of
noise are experienced close to the busiest
airports, with noise from Heathrow at a level
classified as ‘significantly annoying‘
and impacting more people than any other
airport in Europe.”
Yet the CAA has few powers to control noise
and considers that its main statutory duty is to
facilitate aviation growth.
Respondents told us about significant adverse effects on the quality of life for themselves and their families, including sleep disturbance, inability to concentrate, and depression. Many had lost the enjoyment of their gardens. Aircraft noise intrusion, we learned, occurs until well after 11pm, and often before 6am.
People up to 20 miles away from major airports have reported frequent and intrusive noise impacts.
And it’s not just people who live close to airports who are affected. Someone who lives under a flightpath of a major airport that’s 11 miles away recently contacted us to describe what this is like:
“It’s destroying my quality of life. I dread going to sleep because I know that I only have 4 hours of relative peace until the incessant noise starts at 5:45 am. I wake up with anxiety because I know that I will not get any peace for the next 20 hours. I’m starting to dread going outside. It’s causing me stress and chest pain.”
AEF has also been told about significant problems with frequent, intrusive noise impacts on people living 20 miles away from major airports.
There is a sufficient and widening evidence base showing links between aircraft noise and negative health impacts. The impacts of aircraft noise at night are particularly pronounced. A large scale study around Heathrow Airport found that people living under the flightpath were 10-20% more at risk to stroke and heart disease than those not living under the flight path.
In October 2018, The World Health Organisation (WHO) in Europe revised its recommendations on community noise exposure. The WHO now states that, to avoid health impacts, outdoor noise levels should not exceed 55Leq during daytime, or 40Leq at night. AEF advocates for using the WHO guidelines (and any future revisions) as a target for UK aviation noise policy.
In the six years before Covid restrictions, AEF noticed an increase in the number of queries from people who either were experiencing noise for the first time, or were experiencing an intensification of noise from aircraft operating from commercial airports as a result of airspace and operational changes. A survey we carried out in 2021 revealed that, after the relative quiet of Covid lockdown, sensitivity to aircraft noise increased when operations at airports and airfields resumed.
The number of people impacted by aircraft noise, either for the first time or because the noise has intensified, has increased.
Helicopter noise can be especially annoying. In our 2016 members survey, 19% of respondents reported an issue with it.
Here is what the Civil Aviation Authority says about the issue:
“Helicopter noise is far more complex to measure and assess than fixed-wing aircraft noise. This is mainly because helicopters often don’t have to follow predefined routes, like fixed wing aircraft, and because helicopters may hover over a specific area for a while making the impact of the noise last for longer. Also, variations in the speed of the rotor blades means that the way noise travels also varies, and results in an asymmetric noise distribution, i.e. different noise levels from one side of a helicopter to the other.”
The CAA has some information on helicopter noise on its website particularly highlighting where helicopters are allowed to land.
The majority of helicopter queries the AEF receives are about helicopter noise in London. The CAA provides useful statistics on helicopter operations over London, which makes it possible to spot trends. You can access it here. You might find it helpful to reference the statistics if submitting comments or complaints.

If you would like to know a little bit more about helicopter noise in London, the London Assembly report produced in 2006 on helicopter noise is still useful.
Unfortunately, noise from civil aircraft is not a statutory nuisance in the UK, and neither the Environmental Protection Act (1990), nor the Noise Act 1996, offer any protection. Ordinarily, that would leave civil action in the county courts as an option, but the aviation industry enjoys a special exemption by way of the Civil Aviation Act (1982). The Act states the following:
s.76(1) No action shall lie in respect of trespass or in respect of nuisance, by reason only of the flight of an aircraft over any property at a height above the ground in which, having regard to wind, weather and all circumstances of the case is reasonable, or the ordinary incidents of such flight, so long as the provisions of any Air Navigation Order (definition below) and of any orders under section 62 above have been duly complied with.
s. 77(2) No action shall lie in respect of nuisance by reason only of the noise and vibration caused by aircraft on an Aerodrome to which this subsection applies by virtue of an Air Navigation Order, as long as the provisions of any such Order are duly complied with.
Noise from civil aircraft is not a statutory nuisance in the UK.
Air Navigation Orders set out the Rules of the Air
The rules apply to all aircraft, but they are mostly relevant to General Aviation. The Visual Flight Rules are as follows:
Except when necessary for take-off or landing, or except by permission from the competent authority, pilots must not fly:
AEF is often asked whether the noise problem can be challenged under the Human Rights Convention. The case of Hatton and Others v. the United Kingdom (application number 36022/97) is particularly relevant. It was heard by the European Court of Human Rights in Strasbourg in 2003.
The applicants complained of night noise from Heathrow resulting from new aircraft operations, and said that their rights under Article 8 (A8) of the Human Rights Convention (HRC) had been violated. A8 states:
The court accepted that the economic interests of the airline operators and the economic interests of the country necessarily “impinged” on the local community, and their A8 rights. However, the case hinged on how far those rights could be violated, and whether “a fair balance was struck between the competing interests of the individuals affected by the night noise and the community as a whole”. The court decided (12 judges to 5) that a fair balance had indeed been struck. It held that sleep disturbance didn’t amount to an intrusion into private life sufficiently to give it significant weight. It also noted that the number of people affected was very small – and argued that they were free to relocate without suffering financial loss.
However, the opinion of the five dissenting judges is interesting, and potentially useful. They stressed that the judgment had given precedence to economic considerations over a “basic human need”, regardless of the small number of people affected:
When it comes to such intimate personal situations as the constant disturbance of sleep at night by aircraft noise there is a positive duty on the State to ensure as far as possible that ordinary people enjoy normal sleeping conditions.
They also pointed out that sleep deprivation can be used as a form of torture, but only to emphasise the debilitating effects of sleep disturbance (they didn’t seek to invoke Article 3 of the Convention).
There is a positive duty on the State to ensure as far as possible that ordinary people enjoy normal sleeping conditions.
It is possible to be compensated for noise nuisance caused by aircraft – but only in very limited circumstances.
The Land Compensation Act (LCA) (1973) can be a route to securing compensation for people whose houses are devalued by the construction of a new runway. The homeowner must provide evidence that, in comparison with similar, but unaffected properties, their home has lost value as a result of the development.
Following a consultation on airspace and noise in 2017, the Department for Transport (DfT) introduced a number of changes to compensation and insulation policy. Rather than limit assistance towards the costs of noise insulation to homes affected by development, the DfT extended that provision to homes affected by airspace changes. The DfT also removed the requirement that, in order to trigger financial assistance towards insulation for those exposed to noise of 63dB LAeq, there must be a minimum 3dB change. In addition, airspace change sponsors (such as airports) are now encouraged to consider whether compensation might form part of a package of appropriate measures to address significant noise impacts of a proposed airspace change. Finally, where homeowners want to remain in their homes following a change, the airport should offer to pay for full insulation for those homes within the 69dB LAeq contour. (To access the policy document, click here).
AEF broadly supported these policy changes, but we were disappointed that compensation would be left largely to the discretion of airports or sponsors. In addition, increased frequency of noise events from aircraft appear to be out of scope for compensation unless one of the above thresholds is met. We also felt that noise thresholds remained too high, and unless they are located in the immediate vicinity of the airport, few households would be likely to qualify for financial assistance with noise insulation.
The DfT’s Aviation Strategy Green Paper (2018) revisited compensation and insulation policy
Rather than proposing additional national policy requirements on compensation, the Green Paper suggested a local planning authority role. Planning approvals for increases in passenger numbers or flights would routinely set noise caps as planning conditions. Exploring possible additions and alternatives to existing compliance measures, the Paper suggested that, where planning caps were breached, airports could be required to pay compensation to communities – effectively paying for additional growth.
AEF supported the introduction of noise caps within the local authority planning system. However, we felt that the measure relies too heavily on local authorities getting the levels right. We were also concerned about the suggested compliance mechanisms. While airports would be able to exceed cap limits (in return for compensation), communities would be unable to ask for cap limits to be lowered where they are too high. The policy proposals, we felt, were skewed in favour of airports.
The proposals were:
1. to extend the noise insulation policy threshold beyond the current 63dB LAeq 16hr contour to 60dB LAeq 16hr
2. to require all airports to review the effectiveness of existing schemes, including the effectiveness of insulation and whether other factors need to be considered, and also whether levels of contributions are affecting take-up
3. for the Government or ICCAN [the now defunct Independent Commission on Civil Aviation Noise] to issue new guidance to airports on best practice for noise insulation schemes, to improve consistency
4. for airspace changes which lead to significantly increased overflight, to set a new minimum threshold of an increase of 3dB LAeq, which leaves a household in the 54dB LAeq 16hr contour or above as a new eligibility criterion for assistance with noise insulation.
AEF said that the threshold is still too high and insufficiently evidence-based. The DfT should propose a night-time trigger for insulation to reduce sleep disturbance. A 3dB change is equivalent to a doubling of aircraft movements, which is high as the test for significant increase. The overall insulation threshold should be lowered to 54 LAeq in line with recent WHO recommendations. We also said that reviews should be coordinated by ICCAN to ensure consistency in approach.
Please note, however, that following an independent review of ICCAN, the Commission was dismantled in September 2021, a little over two and a half years after its creation. In the summer of 2022, the CAA created a new Sustainability Panel. Though non-statutory, the panel is not independent of the CAA and is not public-facing.

Making a complaint
If people affected by noise issues don’t engage with airports, then airports might conclude there’s no problem.
But avoid overkill. If airports receive multiple complaints from a single person, they might reasonably assume that the problem isn’t widespread.
If you are affected by an aircraft noise issue, it’s likely that your neighbours are too. They might want to raise the issue themselves. Help them out by sharing the airport’s contact details.
Complaining to the airport
If you have an aviation noise problem, then the airport can’t act unless it knows. So, as a first step, consider making a complaint (if you know where the aircraft are flying to and from). The Civil Aviation Authority (CAA), the aviation regulation body in the UK, has a contact list for the main airports; you’ll need to look other airports up online. There are also some useful flight tracker apps that can help identify aircraft and their routes, for example Flightradar24 and ExPlane.
If you’re affected by noise from light aircraft, including helicopters try an internet search to find airfields or heliports near to you, or use a flight tracker, and make contact. Check whether there are any local noise abatement procedures in place and whether these are being followed. If the problem is persistent, request alternative practices.
Where the airfield cannot be identified, if you can get the registration number of the aircraft, you can find the contact details of the owner here and politely ask them if they could avoid overflying your area. If the pilot is in breach of the Rules of the Air, you can complain to the CAA (see below).
For military aircraft, you can raise the issue with the MOD on 0845 600 7580. There’s a useful article on low-flying military aircraft you can read on the GOV.UK website. Possibly, the helicopter noise is coming from aircraft operated by the National Police Air Service or by your local Air Ambulance Service (a coverage map can be found here). Try contacting them to enquire.
When raising a noise issue with any aircraft operator, stress how the noise impacts you, or where relevant, your family.
When raising a noise issue with any aircraft operator, stress how the noise impacts you, or where relevant, your family. For example, if your sleep is affected, explain this in detail, including any side-effects, such as poor concentration, or depression. If you have had to visit your GP because your health is suffering, say so.
Complaining to the CAA
Unfortunately, AEF’s members and members of the public tell us that some airports can be evasive, and even obstructive.
If you believe that there has been a potential breach of aviation law, and your attempts to engage with the aerodrome or heliport have been unsuccessful, one option is to refer your complaint to the CAA. The CAA undertakes to review cases within 20 days. Details of complaints the CAA will consider, and a link to its online complaints page can be found here.
There are still a number of things you can do, and the following list is intended to give you an idea of the actions you can take.
Make your voice heard
AEF has been working to raise the visibility of those impacted by aviation noise. Since 2018, we have been collecting short films and blogs contributed by our members and members of the public from across the UK. Whether you are impacted by commercial aircraft or general aviation noise, if you would like to submit a contribution, please email firstname.lastname@example.org for details.
