One postcode
From a postcode to a sourced answer.
A walk through one search. The street is a real example, and every figure in it is the site's own answer for that street today.
01
Type a postcode, a place or a ZIP
Any full postcode in the UK city regions we cover, a council area by name, or a Bay Area ZIP (New York’s are on the full map). A postcode opens on its own street, with the street’s own figures wherever they exist, never the council’s average.
Opens on TW9 3PZ, Kew, in Richmond upon Thames, under Heathrow’s arrivals: the street’s own noise, air and planes. Hounslow, the council area’s card: its score, the five scores behind it and its official figures, with the full scorecard a click away. Palo Alto, the Bay Area city holding half or more of the ZIP’s residents: its score, its facts and the routes over it.
02
Noise, against the WHO guideline
DEFRA’s modelled aircraft and road noise for the postcode, each drawn against the World Health Organization’s guideline, so a reading says how far over it the street is. Where DEFRA does not map aircraft noise, an estimate from the published routes, which says so.
The example’s noise figures appear here as it loads.
03
Air: the model, and what is measured
DEFRA’s model for the postcode’s own 1 km square, beside the nearest Breathe London sensor and DEFRA monitor nearby, on one scale with the guideline drawn through it. The model is a ring, a measurement a solid mark.
The example’s air figures appear here as it loads.
04
Planes overhead, set by the wind
Planes land and take off into the wind, so the wind decides which way an airport flies, and that decides how many pass over a street. Counted from flight tracking, and checked against the CAA’s monthly totals.
The example’s planes appear here as it loads.

Heathrow's consultation
See the planes over your council.
Whatever your view, one page for each of the 32 councils Heathrow's flights cross: the planes counted over each of its postcode districts, and its official noise, air and flood figures. Today's flights on today's routes, not those of a third runway. The consultation is open until 22 December 2026.

Questions
Before you search.
Where do the figures come from?
From public bodies: DEFRA’s noise and air maps, the Environment Agency’s flood maps, published flight routes from the UK AIP (NATS), ONS crime figures, HM Land Registry prices and more. Every figure names its source and its year.
Is aircraft noise measured?
Mostly it is modelled: DEFRA’s map where DEFRA maps aircraft noise, and an estimate from the published flight routes elsewhere, which says so. The air section adds measured readings from the nearest Breathe London sensor and DEFRA monitor. More in How it works
How are the figures checked?
The planes counts are checked against the CAA’s monthly totals for each airport, and an airport is counted only once its counts pass. Where DEFRA does not map aircraft noise, the estimate from the flight routes is published with its error against DEFRA’s own maps. More in How it works
Which places does it cover?
97 council areas in 13 UK city regions, plus New York's 5 boroughs and 50 Bay Area cities.
Is it free?
Searching is free. Reports and the API have free and paid options: see Pricing.
Can I use it for my business?
Yes: through the API, in your own system, or as one open file of every UK council area, free for non-commercial use. Book a demo to go through your own postcodes.
