Today is the big day: ’s lights will be switched on for 2026 on . And this year, Oxford Street’s display will have a touch of added magic. The shopping stretch’s yuletide illuminations will be going full ‘The Boy Who Lived’ this year to celebrate the launch of the new TV show, scheduled to premiere on HBO on Christmas Day. 

Alongside Oxford Street’s classic star Christmas lights, expect a series of Harry Potter-themed designs. Details of the illuminations are still under wraps, though, so as not to ruin the big switch-on, which usually takes place in early November. In recent years Oxford Street’s festive displays have been made out of eco-friendly materials including LED lights and recycled plastic.

The lights will also make their sparkling debut in conjunction with the new Harry Potter flagship store, which opened on Oxford Street on November 4 (check out all the deets here). 2026 is turning out to be a big year for Potterheads.
