The Asylum Halloween Indoor Festival (London, United Kingdom) 2026

The Asylum returns to the Eutopia Warehouse in Barking on Saturday 31 October 2026, an indoor festival running from 3pm to 11pm with 35 artists across three arenas. Four London promoters have pooled their bookings for it, which is how a single day event ends up with a line up this long.

Wiley tops the bill with a showcase set, with a special guest still to be announced. Kaleem Taylor performs Promesses, Katie Pearl performs Something In The Air and Funky Dee performs Are You Gonna Bang?, with DJ sets from Supa D, Terminal 4, Shenin Amara, Beezo, JAYDAA, Jerome Six, Kismet, Tippa, Wigman, Petchy, DJ S, Poppy Rei, DBo, Jawzy, Spidey G, Darkman Zulu, DJ Nate, DJ Larni, Afro Karl, Big Business and Englishfire, plus a birthday set from DJ Majesty and radio sets from Teeshow of Capital Xtra and DJ Ace of Kiss Xtra. The programming runs through tech house and Afro house.

Tickets range from 5 to 50 pounds with backstage and VIP queue jump options, and last entry is 7.30pm. Entry is 18 and over and physical photo identification is required with no exceptions, so a photo of an ID will not get anyone through the door. Fancy dress is encouraged but not compulsory. The Eutopia Warehouse is at 42 River Road in Barking, in east London. It is a long music festival day for the money.
