Clapham to Putney: Heathrow Early Arrivals
What You Can Do
A Resident’s Guide by The Soundproof Windows – Acousticians, Not Just Window Fitters
Why This Guide Exists
From Clapham to Putney, the first sounds of the day aren’t birdsong — they’re Boeing. If you live in this corridor, you’re likely familiar with the 04:30 wake-up rumble.
This guide is designed to help residents across Clapham, Battersea, Wandsworth, and Putney understand what’s happening, why it matters, and what you can do about it.
What Are Early Morning Arrivals?
Heathrow’s official operating hours are 06:00–23:30, but special dispensation allows up to 16 scheduled arrivals between 04:30 and 06:00. These flights are typically long-haul services from Asia and North America.
Planes descend over central and southwest London on approach to runways 27L and 27R.
Bringing them directly over Clapham, Battersea, Wandsworth and Putney.
- Aircraft altitude: 2,000–2,500 feet
- Frequency: 1 every 90–120 seconds during peak
- Peak external noise: 65–75dB LAmax
These arrivals are the subject of ongoing public concern and legal challenge.
Due to their disruption to sleep and wellbeing
Why Early Flights Feel Worse
It’s not just that they’re loud — it’s that they happen when your body and brain are most vulnerable to disturbance.
- Lower ambient noise levels at night = more noticeable aircraft
- Sleep cycle interference = harder to return to sleep
- Higher impact indoors due to less daytime masking
Residents report that even newer, “quieter” aircraft like the 787 Dreamliner or A350 can still wake them.
Particularly on still, humid mornings.
Why Some Flights Feel Worse Than Others
| Aircraft Type | Typical Noise Profile | What It Feels Like Indoors | LAmax at Ground | Duration Audible |
|---|---|---|---|---|
| Boeing 777 | Deep twin-engine roar, high airframe drag | Window rattle, low-frequency rumble felt in the chest | 70–75dB | 20–30 seconds |
| Airbus A380 | Large, turbulent airframe; landing gear howl | Pressure changes, long “whoosh”, felt even in insulated homes | 68–74dB | 25–35 seconds |
| Boeing 747 | Noisy four-engine relic, rarely used now | Harsh roar, bassy, disruptive — a dying breed | 72–77dB | 25–40 seconds |
| Boeing 787 | Modern turbofan, quieter core, smoother wake | Noticeable but tolerable, distant sounding unless very low | 63–70dB | 18–28 seconds |
| Airbus A350 | One of the quietest in class, advanced aerodynamics | Barely audible unless windows are open or aircraft is very low | 60–67dB | 15–25 seconds |
| Airbus A330 | Mid-size wide-body; older engines, moderate drag | Low rumble, audible over background sounds indoors | 65–72dB | 20–30 seconds |
| Airbus A320 | High-pitched whine, most frequent over London | Light buzz — but the frequency becomes the issue | 60–68dB | 15–22 seconds |
| Boeing 737 | Slightly higher pitch, buzzier than A320; newer MAX quieter | High-pitched but short; can be grating over time | 61–69dB | 15–20 seconds |
| Embraer E190/E195 | Smaller fuselage, higher pitch, whiny engine tone | Sharp, quick flyover; short but attention-grabbing | 58-65dB | 12-18 seconds |
| Cargo Planes | Often older aircraft, night flights, heavier profiles | Guttural growl, often wakes residents between 4–6am | 70–78dB | 30–45 seconds |
Areas Affected in This Corridor
| Area | Noise Experience | Typical Aircraft Overhead |
|---|---|---|
| Clapham | High-frequency arrivals from 04:30 onward | 777, A380, 787, occasional cargo |
| Battersea | Directly under the flight path, strong early peaks | 787, A350, A330, some short-haul |
| Wandsworth | Frequent early arrivals, especially on 27R path | Mixed fleet, often Dreamliners |
| Putney | Overlap of both 27L & 27R paths, near-constant | All long-haul types, heavy-volume |
What Residents Are Saying
