Oxford Street Christmas lights to switch on 9 November with Harry Potter theme

Oxford Street's Christmas lights for 2026 will be switched on Monday 9 November, according to Time Out London. This year the display takes on a Harry Potter theme to mark the launch of the new Harry Potter and the Philosopher's Stone TV show, which is scheduled to premiere on HBO on Christmas Day.

Alongside Oxford Street's classic star lights, visitors can expect a series of Harry Potter-themed designs. Details of the illuminations are being kept secret so as not to spoil the switch-on. In recent years the street's festive displays have used eco-friendly materials, including LED lights and recycled plastic.

The lights arrive alongside the new Harry Potter flagship store, which opened on Oxford Street on 4 November.

The switch-on event will open early at around 2pm on 9 November. The main festivities begin at 4.30pm, and the event finishes at 7pm. Sam Thompson will host, and Marvin Humes will play DJ sets throughout the afternoon.

London's festive traditions, such as carol singers, decorated trees and Christmas lights, have already started to return across the city.
