There is nothing quite like London at Christmas. The lights are back for 2025. Angels glow over Regent Street, Oxford Street is a sky full of stars, and the giant bells and Christmas tree are up in Covent Garden. In this guide, we’ll take you through the key switch-on dates, the best spots to see the lights, and how to navigate the crowds (mostly manageable). Your excuse to grab an overpriced Baileys hot chocolate is officially valid. Put on your comfiest shoes, keep your phone handy for festive snaps, and enjoy London doing what it does best at Christmas.
