Planes over Barnet today
For Heathrow's expansion consultation, open until 22 December 2026.
Whatever your view, these are the figures for Barnet now: the planes from Heathrow counted over each of its postcode districts, and the borough's noise, air and flood figures from official data. They are today's flights on today's routes, not those of a third runway. Sky Score takes no side in the consultation.

Planes from Heathrow, district by district
Planes land and take off into the wind, so the weather decides which way Heathrow flies, and that decides how many pass over each place. Counted over each postcode, January to August 2026.
Each cell gives the most planes over any one postcode of the district on that kind of day, then counts the district's postcodes by how many pass over them a day: 100 or more, 10 to 99, or under 10.

Barnet: every figure we publish, with its score
What counts as overhead
Overhead means more than halfway up the sky (48.5 degrees or more) and below 7,000 ft, the CAA's definition of an overflight (CAP 1498). A day counts as one way when 80% of its flights used that way.
