London's busiest shopping street has officially gone traffic-free. As of Monday 26 October, Oxford Street is closed to vehicles along almost a full kilometre between Orchard Street and Great Portland Street, ending decades of talk about pedestrianising the famous retail strip.

The ban covers private cars, buses, taxis, cycles, e-scooters and pedicabs, with Transport for London enforcement officers issuing Penalty Charge Notices to anyone who strays into the zone. Mobility scooters are the sole daytime exception. Freight and delivery vehicles get a narrow window, allowed on serviced routes only between midnight and 7am. Parking is no longer permitted in the pedestrianised stretch, so some parking bays, Blue Badge spaces and taxi ranks have moved to nearby streets.

The timing is no accident: the switch-on of the Oxford Street Christmas lights in early November is one of the city's biggest festive moments, and this year's crowds will be the first to experience the street without dodging buses and black cabs.

This is phase one of a bigger overhaul. From next year, TfL plans to raise the road surface to pavement level, creating a single flat plane for walkers. The first two sections are due to be finished in spring 2027 and will include new public squares that could host events. Greening the street and adding more places to sit between shops are also on the agenda.

Mayor Sadiq Khan has billed the change as a defining moment for the capital, arguing that transforming the nation's high street into a world-class pedestrian space will boost jobs, draw flagship retailers alongside new shops and workplaces, and bring everything from fashion shows to cultural events to the West End. For visitors, the practical effect is simpler: more room, calmer crossings, and the freedom to wander between department stores without breathing in exhaust fumes.

Anyone heading to London for festive shopping now has a rare window to see a major thoroughfare reinvented in real time. Expect crowds, especially around the lights switch-on, but also an easier, more relaxed experience on foot than at any point in living memory.
