The provisional data has been published by The Department for Transport, taken from police force data submitted up to May 11, 2026.
While the number of deaths on the capital’s roads has generally declined in recent years, serious injuries have climbed to their highest level since 2018.
Westminster recorded the highest overall number of people killed or seriously injured (KSIs), with 265 casualties — up from 238 the previous year.
Southwark followed with 211 KSIs, while Lambeth, Hounslow and Croydon also ranked among the boroughs with the highest totals.
The figures highlight the continuing challenges facing Transport for London and London councils as they work towards the Mayor’s Vision Zero target of eliminating road deaths and serious injuries in the capital by 2041.
