Cycling Collisions in London, Borough by Borough

Westminster is the London borough where the most cyclists are hurt. Between 2021 and 2025, police recorded 2,060 collisions there in which a person cycling was injured, ahead of Southwark (1,842) and Lambeth (1,729). Eight central boroughs account for half of London's total. But the boroughs with the most collisions are not the ones where a collision is most likely to be serious. That list is led by Richmond upon Thames, where 34% of collisions killed or seriously injured the cyclist, against 20% across London. Busy central streets produce many low-speed collisions. Faster outer roads produce fewer, and worse, ones.

Which London borough has the most cycling collisions?

Westminster, by a clear margin, and it leads on serious collisions too (441). This is mostly a story about how many people ride there. Westminster, Southwark, Lambeth and Tower Hamlets hold the bridges, the West End and the City fringe, which is where London's cycling is densest. More riders on more crowded streets means more collisions, even if each journey is no riskier than one elsewhere.

Where is a cycling collision most likely to be serious?

In outer London. Richmond upon Thames (34%), Bexley (31%), Sutton (27%), the City of London (25%) and Bromley (25%) have the highest shares of collisions in which the cyclist was killed or seriously injured. Apart from the City, these are outer boroughs with faster roads, longer gaps between junctions, and a lot of sport and leisure riding. Richmond stands out: it ranks 13th for collisions but 6th for serious ones, ahead of boroughs with twice its total.

At the other end, Waltham Forest (14%), Brent (15%), Tower Hamlets (15%) and Camden (16%) have the lowest serious shares. Waltham Forest and Camden have both built a lot of protected cycle track and low traffic neighbourhoods over the past decade. This data cannot prove that is the cause, but it is the pattern you would expect if slower, calmer streets turn serious collisions into minor ones.

The full table: all 33 boroughs

Collisions in which at least one cyclist was injured, 1 January 2021 to 31 December 2025, by the borough where the collision happened. The chart above shows the top ten and re-sorts; the table has every borough. "All injuries" counts collisions in which a cyclist was injured. "Serious" counts those in which the cyclist was killed or seriously injured.

Does a high number mean a borough is dangerous to cycle in?

No, and this is the most important thing to understand about the table. A count of collisions measures two things at once: how risky the streets are, and how many people ride on them. Westminster tops the list largely because so many journeys pass through it. The City of London is one square mile and still records more collisions than Barnet, which is about 30 times its size, because a huge share of central London's commuters ride through it.

To compare risk fairly you would divide by the distance cycled in each borough, and no public dataset measures that well enough at borough level. So read the counts as "where the harm is" rather than "where you are most at risk". The share that are serious is the better guide to how bad a collision tends to be when it happens.

Borough totals hide the real pattern, which is street by street. Within every borough, collisions bunch along a handful of main roads and junctions, and whole neighbourhoods beside them record almost none. The map below shows each collision since 2025 in which a cyclist was killed or seriously injured. Zoom into your own borough to find the roads to avoid.

We covered which kinds of road and junction those are in Is cycling in London safe?: 62% of collisions are on A roads and at least 70% are at junctions. You can explore the full map, with cycleways and low traffic neighbourhoods switched on, on the London map.

Notes and sources

• Collision data: Transport for London road-collision records, compiled from police reports, for 1 January 2021 to 31 December 2025. We counted collisions in which at least one casualty was travelling by pedal cycle, and attributed each to the borough named in the record. "Serious" means the cyclist was killed or seriously injured.
• Boroughs are the 32 London boroughs plus the City of London. Collisions on a borough boundary are counted once, in the borough the police recorded.
• Counts are not rates. No figure on this page is adjusted for how much cycling happens in a borough. Transport for London publishes borough-level casualty statistics in its road safety reports.
• Method: aggregated by Cyclemate on 19 September 2026 from the dataset behind the collision layer on our London map. We will update this page when a new year of data is published.
