Road Risk Score
London ranks 103 of 125 towns we score — band B, below average
43 people killed or seriously injured per 100,000 residents, 8.9 vehicle crimes per 100,000, 68.3% of collisions involving someone outside a car, and a five-year trend of -9.8%. How the score works.

London’s busiest collision clusters (2025)
Each circle is a ~100m cluster of police-reported collisions. Larger circles = more collisions; red = at least one death. Click a circle for details.

These locations recorded multiple collisions in at least four of the last five years (2021–2025) — a persistent pattern, not a one-off bad year.

What to do with this: if your regular routes cross the junctions above, they deserve extra care at peak times — these aren’t random locations, they’re where collisions repeat. For context, London’s rate of 233 per 100,000 residents compares with an average of 220 across the 125 areas we track. A junction with a documented five-year history is also the strongest evidence a campaign can put in front of a councillor.
Vulnerable road users in London in 2025: 4,522 collisions involved a pedestrian, 5,611 a cyclist and 4,111 a motorcyclist — overall, 233.3 collisions per 100,000 residents.
Area definition: figures cover Greater London (all boroughs, ONS E09*). Per-100k rates use the mid-2023 ONS population estimate for the named town or district; where the area is radius-defined, treat the rate as indicative.
These figures come from the Department for Transport’s STATS19 dataset — every collision reported to the police in 2025 — clustered to roughly 100 metres and labelled via OpenStreetMap. Only police-reported incidents are included, so minor damage-only bumps are undercounted. See the full UK hotspots analysis for the national picture and methodology.
Need this cut a different way? A junction’s full history, cyclist or pedestrian casualties on their own, or a before-and-after on a scheme: we produce those, free for community groups, campaigners and journalists.

What actually changes the odds in London
Data is only useful if it changes what you do. These three are picked from London’s own figures above, each with the number that prompted it. Every guide explains how the thing works before it suggests buying anything, and most cost less than a third of a typical insurance excess.
Helmet camera
£50–£200
27% of collisions in London involve someone on a bike. In a disputed pull-out, footage from the rider's viewpoint is what settles liability.
How it works →
Alarmed disc lock
£20–£50
Motorcyclists are in 20% of London's collisions, and bikes are also lifted rather than ridden away. An alarmed disc lock covers the theft half for about £30.
How it works →
Dashcam (parking mode)
£50–£150
22% of collisions here involve a pedestrian, and those are the cases most often argued over. Footage removes the argument.
