1) Ford Fiesta – 94,206 registrations (Q2 2021) It's no surprise to find the Fiesta topping the used car chart. After all, it's been Britain's best-selling new car for the more than a decade and has only recently come under serious competition from the latest Vauxhall Corsa.

In 2026, the landscape of the "most used" car in London has shifted dramatically toward electric and hybrid models due to the expansion of the Ultra Low Emission Zone (ULEZ) and the high cost of fuel. The Tesla Model 3 and the Kia Niro EV are among the most frequently seen private vehicles on London streets, as they allow owners to avoid daily congestion charges. However, if we consider "usage" in terms of high-frequency road time, the Toyota Prius and Toyota Corolla Hybrid remain the undisputed kings of the city, serving as the primary workhorses for London's massive private hire (Uber/Bolt) fleets. For families, the Nissan Qashqai continues to be a top seller for its practicality in urban environments. Additionally, the iconic LEVC TX (the electric black cab) is technically one of the most used "specific" vehicle models in central London, as thousands of these zero-emission taxis operate 24/7. As London aims for a "Net Zero" transport system, the "most used" car title is increasingly becoming a battle between efficiency, tax-compliance, and the infrastructure support for electric charging.
