London's Halloween season is a multi-week club calendar, not a single night. Mood tracks 104 confirmed Halloween-tagged parties across the city for the window between October 23rd and October 31st, 2026, spanning afro house at Camden's Roundhouse, goth and metal at Islington's Electrowerkz, and swing bands playing costume nights in Deptford. Six parties stand out for how differently they treat the same date.
Most of the calendar clusters on October 31st itself, a Saturday this year, which means the city's bigger rooms are running one-off specials rather than their usual weekly nights. A handful of parties land the weekend before, for anyone who wants the costume without competing with the Saturday crowds.
Labyrinth: Caiiro x Da Capo x Enoo Napa at Roundhouse
Roundhouse, the former railway turntable shed in Camden that has hosted everything from Jimi Hendrix to the Barbican's overflow programming, gives over its Halloween date to a five-hour back-to-back-to-back set from Caiiro, Da Capo and Enoo Napa - three of South African house and afro house's most consistent international touring names. It is a format built for a single, unbroken set rather than a lineup of short slots, which is unusual for a room this size. The details: Saturday, October 31st, Roundhouse, tickets via Resident Advisor. Find the event on Mood.
A Spooky Swingin' Sunday at Jamboree
Jamboree, the small Deptford room built around live jazz and swing, hosts Elise Roth's nine-piece band for two sets of Halloween-themed swing, with prizes for the best costume. On paper it is the least club-coded party on this list - no DJs, no bass - but Mood's data tells a different story: this show rates a full 1.0 on both danceability and organicness, the highest of any of the six parties covered here, ahead of every house and disco night in the round-up. A nine-piece band playing live in a room built for dancing outperforms the club nights on the exact metric they are supposed to own. The details: Sunday, October 25th, Jamboree, Deptford, tickets via Eventbrite. Find the event on Mood.
Voodoo Halloween Ball at Electrowerkz
Electrowerkz, the Islington venue built into a former print works and long associated with the goth and industrial scene through nights like Slimelight, runs an eight-zone Halloween ball across five floors - metal, emo, pop-punk and goth DJs, a live stage and a karaoke room, under one roof. Mood rates it 0.9 on undergroundness, roughly double the 0.45 average across the six parties in this guide, which tracks with the venue's identity: this is the one Halloween night on the list built for a scene rather than a general crowd. The details: Friday, October 30th, Electrowerkz, Islington. Find the event on Mood.
Zombie Pirate Ship at Crown Pier
Crown Pier on Victoria Embankment runs four separate Halloween boat parties this season - Zombie Pirate Ship is the one leaning hardest into the theme, with NYCity Soundz, MISSFIT, VanRock and Eddie Van Poppel playing house and club classics across two floors as the boat moves along the Thames, before a late-night after-party. It is the only outdoor-rated party in this guide, for the obvious reason that half of it happens on open water. The details: Saturday, October 31st, departs Crown Pier, tickets via Resident Advisor. Find the event on Mood.
Jack Your Body LDN at Stringfellows
Jack Your Body LDN takes over Stringfellows in the West End for a daytime house and disco session, with Wayne Soul Avengerz, MTCO and George Goodson on the lineup. Running a Halloween date as a day party rather than a night-through-dawn rave is a smaller, deliberate choice - it reads as a party for people who still want their evening free for a second one. The details: Saturday, October 31st, Stringfellows, West End. Find the event on Mood.
Insomnia London: Halloween Special
Insomnia's Halloween edition brings a Club Glow label takeover into a night otherwise built around jungle, drum and bass, grime and breaks, with Killa P, Pete Cannon, Mantra and Benton among the names on the bill. It sits closer to London's core UK bass scene than to costume-party territory, which is exactly the point for a crowd that wants the date without the theme taking over the music. The details: Saturday, October 31st, Tottenham Arts Collective. Find the event on Mood.
What London's Halloween calendar actually looks like
Six parties, six different rooms: a five-hour afro house set at a former railway shed, a five-floor goth and metal ball, a live swing band outdancing every DJ on this list, a boat that is one of four run from the same pier, a daytime disco session, and a bass night that treats Halloween as a scheduling detail rather than a theme. London's Halloween calendar is not one costume party repeated across venues - it is dozens of scenes each running their own version of the same date, which is the pattern behind the 104 parties Mood has tagged for this window.
