London's official taxis, black cabs can be hailed in the street or at designated ranks located in prominent places, including many train, Tube and bus stations. They can also be booked through the Gett app and by phone. If the yellow taxi sign on the front is illuminated, the cab is available for hire.

Hailing a taxi in London in 2026 is a blend of traditional gestures and modern tech. To catch a classic Black Cab on the street, you must look for the yellow "TAXI" light on the roof; if it's illuminated, the cab is available. Stand on the edge of the pavement and simply extend your arm straight out—no whistling or frantic waving is necessary. London drivers are experts at spotting a single raised hand. Once the driver pulls over, you typically walk to the front passenger window before getting in to tell the driver your destination; they will then unlock the rear door for you. In 2026, almost all Black Cabs are electric (LEVC models) and must accept credit/debit cards by law. If you are in a busy area like Piccadilly Circus where street hailing is difficult, look for a "Taxi Rank" (signified by a yellow sign) where cabs line up in order. Alternatively, you can use the Gett or Free Now apps to "hail" a black cab digitally, which provides the convenience of an Uber but uses a licensed London cabby who has passed "The Knowledge"—the world's most difficult geography test for drivers.
