The law on helicopters, explained

The law

No trespass or nuisance for lawful, reasonable-height flight

You cannot sue an aircraft operator for trespass or nuisance 'by reason only of' a flight over your property at a reasonable height, having regard to wind, weather and circumstances, provided the Air Navigation Order and any s.62 orders have been complied with. If the flight breaches those rules, the protection does not apply. Source

Strict liability for surface damage

If an aircraft in flight, taking off or landing (or anything falling from it) causes material loss or damage to a person or property on land or water, compensation is recoverable without proving negligence or intention, unless the injured person's own negligence caused or contributed. Source

Aircraft noise is not a statutory nuisance

Councils cannot use the statutory nuisance regime against aircraft noise (other than model aircraft). Source

Endangering an aircraft

A person must not recklessly or negligently act in a way likely to endanger an aircraft or anyone in it. Source

Endangering any person or property (the general low-flying safety offence)

A person must not recklessly or negligently cause or permit an aircraft to endanger any person or property. Source

Dropping articles and animals

Articles or animals must not be dropped (including projected or lowered) from an aircraft in flight so as to endanger persons or property; dropping to the ground over the UK needs an aerial application certificate or CAA permission. Exceptions include saving life or emergency jettison, fine sand or water ballast, navigation, tow ropes at an aerodrome, and lowering from a helicopter where its airworthiness certificate or flight manual expressly permits. Source

Power to restrict or prohibit flying

The Secretary of State may by regulation prohibit, restrict or impose conditions on flights in the public interest (large gatherings, displays, national defence). Breach is an offence. This is how temporary restrictions are made. Source

Take-off and landing in congested areas

An aircraft must not take off or land within a congested area of a city, town or settlement, except at an aerodrome, in accordance with CAA-notified procedures, or at a non-aerodrome site with CAA permission. Also no take-off or landing within 1,000 m of an open-air assembly of more than 1,000 people, except at an aerodrome, in accordance with CAA procedures or at a site with the organiser's written permission. Source

CAA permissions under the Rules of the Air

Where the Rules allow a CAA permission, it can cover a class of aircraft or one aircraft, with conditions. Source

Minimum heights (SERA.5005(f)) - congested areas

Under VFR an aircraft must not fly over congested areas or open-air assemblies below 300 m (1,000 ft) above the highest obstacle within 600 m of the aircraft, nor elsewhere below 150 m (500 ft) above ground or water, except for take-off or landing or with competent authority permission. CAA's breach page paraphrases this as 1,000 ft within 600 m over congested areas and 500 ft from any person, vessel, vehicle or structure elsewhere. The legislation.gov.uk text checked is the original (adopted) EU version; a UK note says it may since have been updated, so confirm the current UK-retained wording before quoting a section number. Source

CAA general permission: helicopters manoeuvring below minimum heights

ORS4 No.1496 (Version 1, 28 June 2021, current) gives general permissions and authorisations for exceptions to the (UK) SERA minimum height requirements. A search summary says it covers manoeuvring helicopters flying below 500 ft under SERA.5005(c) and (f) subject to conditions; the page itself did not confirm helicopter detail, so read the PDF before quoting. Source

Landing on land: owner's permission

Landing a helicopter on someone's land without the owner's permission is not covered by the s.76 overflight protection, which concerns flight over property; it is ordinary common-law trespass. No primary source was read for this point, so treat as a drafting note requiring legal review. Source

Royal Parks: no helicopter landings

Without the Secretary of State's written permission, no one may, except in an emergency, land a helicopter or other aircraft in a Royal Park or enter a Park from the air. Source

Royal Parks: model aircraft

Using kites or model aircraft can be restricted by notice or on a constable's request (reg 3(13)(b)). Source

Planning

Temporary use of land - 28 day rule

Planning permission is not needed for using any land 'for any purpose' for up to 28 days in total in a calendar year (of which no more than 14 days may be for a market or motor racing), plus any moveable structure. The class does not exclude helicopters by name and does not list aircraft. Development is NOT permitted where the land is a building or within a building's curtilage, caravans (except festivals), SSSI motor sport, clay shooting or war games, advertising, or camping (except festivals). Class B.1(a) was omitted from 6 April 2016. Whether a given helicopter landing site is lawful also turns on the aviation rules (Rules of the Air Sch 1 para 5 bars take-off/landing in a congested area except at an aerodrome, CAA procedure or CAA-permitted site) and landowner permission. Class BA (extra 28 days) applied only to the 2020-2021 'relevant period'. Source

London Heliport operating limits come from planning

Wandsworth Council's release (2018) states the heliport's consent dates from the former GLC in the 1970s, allows operation within limits on opening hours, a daily cap of 80 movements and an annual limit of 12,000 movements, not counting emergency or military operations, and that 'there is nothing that can be done to curtail the site's operations under planning laws' beyond that. Consultative group minutes (23 Jan 2017) confirm the 12,000 annual cap and that police, military, air ambulance, Government VIP and Royal Family movements do not count against it; reported 2016 total 11,352. Current permission text not seen. Source

Consultative group minutes: 12,000 cap and exemptions

See above; primary minutes of the London Heliport Consultative Group, Monday 23 January 2017. Source

2006 report on planning and the heliport

London in a spin para 5.3 says London Heliport's planning permission has a noise control regime linked to it; the report also notes a 1996 court ruling that a helicopter landing site claiming not to need permission did require it (page text at ~lines 1078-1080 of the PDF). Para numbers should be rechecked against the PDF before quoting. Source

Emerging policy: no new heliports

Wandsworth's 2018 release says the Mayor's then-draft London Plan proposed refusing any new heliports. Adopted London Plan wording was not checked. Source

Enforcement

Pleaded guilty to two offences of low flying over congested areas; date 06/03/2025; Mansfield Magistrates' Court; fine GBP 1,280. Source: CAA 'CAA prosecutions 2024-2025' PDF. Source

CAA assesses every report for evidence of a breach and its impact on aviation or public safety; 'do not have the resources to investigate every report'. Low flying is listed among things it can investigate. All CAA prosecution annual PDFs are the primary source for outcomes. Source

CAA: aircraft noise is not a breach of aviation regulations. Only breaches (e.g. low flying, endangerment arts 240/241) can be investigated. Statutory nuisance route is closed (EPA 1990 s.79(6)). Source
