Halloween falls on a Saturday this year which, in London, is the difference between a nice-to-have and an actual event.
If you've ever wondered whether Halloween is even really "a thing" in London, the honest answer is: more than you'd think, and growing every year. There are Halloween decorations everywhere, even in the supermarkets and if you go out on the Friday or Saturday night nearest to the 31st, you will certainly see a lot of people in costume, with tubes and central London rammed with revellers heading to parties. With Halloween landing on Saturday 31 October 2026, this year is shaping up to be one of the biggest the city has seen with a proper spooky weekend rather than a single midweek evening squeezed in after work.
Whether you're bringing the kids, going all-out for a Harry Potter-themed weekend, or hunting for London's best haunted club night, here's everything worth knowing and exactly where to base yourself for it.
Yes, and increasingly so. Decorations appear in shop windows and supermarkets from early October, pubs dress up their staff and their bars for the weekend nearest the 31st, and while trick-or-treating is smaller-scale than in the US, plenty of London neighbourhoods do embrace it. As a rule, if a house has a pumpkin outside and the lights on, it's a safe bet that a knock and a "trick or treat" will be welcomed.
Where London does Halloween properly is nightlife and immersive events, this is where the city genuinely goes big. Areas like Soho, Camden, and East London, particularly Shoreditch, are known for their vibrant Halloween celebrations, and the streets around the London Dungeon on the South Bank become especially atmospheric for the occasion.
If there's one Halloween experience in London worth planning a trip around this year, it's this one. From 16 September to 8 November 2026, Warner Bros. Studio Tour London, The Making of Harry Potter transforms for Dark Arts, its annual Halloween takeover. Step into the Great Hall to find it filled with over 100 hand-carved pumpkins floating above the house tables, exactly as seen in Harry Potter and the Philosopher's Stone, alongside dramatic Death Eater projections and atmospheric dim lighting throughout the sets.
New for 2026, visitors can uncover the secrets of sound effects and Nagini in the Creatures Workshop, plus an interactive wand combat-learning session led by the franchise's own wand choreographer. For the truly committed, a darker after-hours event called Nox runs over three nights - 29th, 30th and 31st October though it's already sold out for 2026.
One important booking note: Halloween season tickets, especially October weekends and Halloween week itself, typically sell out two to three months in advance. If this is on your list, book now rather than later.
For an evening that mixes genuine spectacle with proper autumn atmosphere, Halloween at Kew Gardens runs from 16 October to 1 November 2026. After dark, the gardens transform into a 1.5km illuminated trail, with live performers, fire artists, and spooky installations winding through the grounds. New for 2026: a brand-new Cursed Tomb and an all-new Monster Disco finale, alongside returning favourites including Dracula's Lair and the Headless Horseman.
Sessions run from Daylight and Twilight through to Moonlight, with the scare factor increasing as darkness falls making it a genuinely flexible option for couples, families, or anyone who wants proper Halloween atmosphere without committing to a full night out. Kew sits in West London, which makes it a particularly easy add-on for anyone based in Notting Hill or South Kensington for the weekend with dinner beforehand, the illuminated trail after, and a short journey back to a proper apartment rather than a long trek across the city late at night.
October half term runs from 26th to 30th October in 2026 landing directly on top of Halloween weekend, which makes this an unusually good year for a family trip built around it.
Included with admission to the London Dungeon this half term is a Halloween special, Curse of the Mummy which is a historical show based on the true story of the Unlucky Mummy, a cursed artefact delivered to a London museum during the Egyptomania phase of the Victorian era. It's a strong option for older kids and teenagers who've outgrown cute pumpkin trails and want something with a bit more bite though it's worth checking the age guidance before booking, as it isn't aimed at younger children.
For families with a Harry Potter-obsessed child, Dark Arts at the Studio Tour is, by common consent among parents, basically compulsory which is magical and atmospheric rather than genuinely frightening, and one of the best ways to spend a day of half term.
High Street Kensington also runs a family Halloween trail to get everyone in a spooky mood that is a lower-key, free option for those staying nearby who want an afternoon of dress-up without booking anything in advance.
Halloween falling on a Saturday in 2026 makes it the single biggest club night of the year in London. Expect major venues across Mayfair and Soho which among them some of the city's best-known nightclubs to go all out with decorations, costumes, and dedicated Halloween events, alongside neighbourhood hotspots in Dalston and Peckham for a more underground, alternative night.
Whichever part of the city you end up in, the pattern holds across London: on the Friday and Saturday nights nearest the 31st, central London and the tube network fill with people heading to parties in the costume even if the day itself, for most residents, passes with barely a stir outside a few streets with the lights on for younger trick-or-treaters.
One genuinely new addition to London's Halloween calendar this year: The Nightmare Realm, one of Europe's most famous Halloween attractions, is coming to London for the first time in October 2026. It takes over Avery Hill in Greenwich for eighteen selected nights from 9 October to 1 November, themed "A Nightmare From Overseas" which is an immersive horror experience with live actors, elaborate sets, and special effects, having originated in Ireland before building a serious reputation across Europe.
For visitors staying near Liverpool Street or Farringdon, Greenwich is a straightforward journey via the DLR or riverboat which is worth combining with an afternoon exploring Greenwich Park and the Cutty Sark before the evening's scares begin.
Book everything early. Nearly every major Halloween attraction in this guide that has Dark Arts, Halloween at Kew, the Nightmare Realm's most popular nights which sells out weeks or months in advance. If a specific event is the reason for your trip, book the moment you've settled your dates.
Plan your transport around the weekend crowds. With Halloween landing on a Saturday, expect the tube network and central London streets to be considerably busier than a typical weekend from Friday evening onward. Building in extra time and knowing your route home before you head out which makes the night considerably smoother.

Costumes are genuinely embraced, but keep it appropriate. Full-face masks are generally restricted for adults at ticketed attractions such as the Studio Tour, and family-friendly outfits are expected at daytime and family events. Save the more elaborate or graphic costumes for evening nightlife venues.
If you're trick-or-treating with children, stick to well-lit streets, go in a group, and only knock where a pumpkin and porch light signal a welcome. London's neighbourhood character means this varies significantly street to street asking locally or checking a neighbourhood Halloween trail (such as the one in Kensington) is often the easiest way to find where it's genuinely embraced.
Halloween in London isn't a single-venue event as it's spread right across the city, from Leavesden in the north to Kew in the west and Greenwich in the south east. That geography makes where you're staying more important than for almost any other event on the London calendar, because your evening will likely involve at least one journey across town, in costume, late at night, alongside thousands of other people doing exactly the same thing.
D'Montrio's eight Zone 1 properties put you within easy reach of nearly every event in this guide. Notting Hill and South Kensington sit closest to Kew Gardens' illuminated trail with dinner beforehand, the trail after dark, and a short journey home rather than a cross-city trek at midnight. Liverpool Street and Farringdon Apartments connect easily to Greenwich for The Nightmare Realm via the DLR, and to Soho and Shoreditch's nightlife scene for those planning a proper night out. Baker Street and Fitzrovia sit centrally for the Studio Tour's shuttle transfers and for an evening split between central London's bars and pubs.
And for a night that almost certainly means arriving home later than planned, in a costume that won't survive a shared hotel corridor gracefully and a D'Montrio apartment offers what most hotel rooms can't: your own front door, a proper kitchen for the inevitable 1am snack, and a living room to actually unwind in before the next day's plans begin.
Book D'Montrio Notting Hill or South Kensington for Halloween at Kew, or Liverpool Street and Farringdon Apartments for Greenwich's Nightmare Realm and central London's nightlife scene which is your base for the spookiest weekend of the year.
With Halloween falling on a Saturday and October half term landing the same week, 2026 is genuinely one of the better years to build a proper London trip around it which is family-friendly by day, atmospheric and immersive by evening, and with enough spread across the city that there's a fitting event whichever part of London you're staying in.
Book the big-ticket events early. Pick a neighbourhood that puts you close to the ones that matter to you. And whatever London gives you this Halloween that has a floating-pumpkin-filled Great Hall, an illuminated trail through ancient trees, or simply a very loud Saturday night in Soho with a proper base to come back to afterwards makes all the difference.
