How far from Heathrow can you hear aircraft noise?

Aircraft noise from Heathrow can be significant up to 15-20 miles away, particularly under approach paths. Areas like Richmond and Putney, well into central London, experience notable noise during certain operations.

Does aircraft noise affect property values near Heathrow?

Studies consistently show airport noise reduces property values, typically by 5-15% depending on severity. The uncertainty around third runway expansion creates additional risk for properties in potentially affected areas.

What about the third runway - should I avoid buying nearby?

The third runway's future remains uncertain. If you're considering a property in the potential expansion zone (Harmondsworth, Sipson, Longford) or under likely new flight paths, factor in significant risk. The project could proceed, be delayed indefinitely, or be cancelled entirely.

Will runway alternation improve noise for my area?

Runway alternation provides some relief during landing operations, but the benefit varies by location. Areas under departure paths don't benefit from alternation in the same way. A flight path report can show you the specific patterns for your address.

Are early morning flights a problem at Heathrow?

For many residents, the 4:30am-6:00am period is highly disruptive. While technically outside the strictest night restrictions, these early arrivals wake many people. Around 80% of night flights occur during this early morning window.

Heathrow Airport flight paths: check if your home is affected.

Heathrow is Europe's busiest airport, handling a record 84.5 million passengers in 2025. With two runways operating at near-maximum capacity and a third runway now back on the government's agenda, understanding aircraft noise is essential for anyone buying property in West London, Surrey, or Berkshire.

Which areas are affected?

Heathrow's noise impact extends from Richmond in the east to Windsor in the west, with a wide band of communities affected in between. The areas listed above all sit within corridors that can see significant aircraft activity — but exposure varies depending on wind direction and which runway is in use.

The third runway — and what it means for buyers

In early 2025, the UK government signalled renewed support for Heathrow's third runway as part of plans to boost economic growth. The proposed 3.5km runway would be built to the northwest of the existing airport. If it proceeds, the village of Harmondsworth — including its medieval tithe barn — would be demolished, and parts of Sipson and Longford would also be cleared.

For buyers, this creates two distinct risks. Properties in the potential expansion zone face possible compulsory purchase. Properties in areas currently unaffected but under likely new flight paths could see dramatic increases in noise. Neither risk is certain — planning, legal challenges, and environmental reviews could take years — but both are material.

Heathrow also operates a runway alternation system that gives communities periodic relief from landing noise, but this only applies to arrivals. Departure patterns are less predictable and depend on aircraft type, weight, and air traffic control.

Why a viewing won't tell you

Heathrow operates in "westerly" mode around 70% of the time and switches to "easterly" when winds change — meaning the same property can experience completely different aircraft activity on different days. Early morning arrivals between 4:30am and 6:00am are the most common noise complaint. A viewing, even at peak hours, will not capture this pattern.

Frequently asked questions

How far from Heathrow can aircraft noise be significant?

Areas well into central London experience notable noise during certain operations. The specific impact at your address depends on wind direction, runway in use, and time of day — all of which our report analyses from historical data.

Should I avoid buying near the proposed expansion zone?

That depends on the specific property and the stage of the third runway project. Our report can help you understand current flight exposure and flag proximity to areas at risk from future change.

Will runway alternation help my area?

Alternation provides relief during landing operations, but the benefit varies by location and does not apply to departure noise. Our report shows the specific patterns for your address across both modes of operation.
