The event has traditionally been held in the Olympia Grand Hall for 49 years, but this year it will exceptionally not be possible. The Olympia Grand Hall is closed for renovations and will not be ready in time. Event director Simon Brooks told Horse And Hound that the event is getting even better this year with the new location, despite the venue change. The event may also remain in ExCel Center instead of Olympia from now on. The accessibility in the ExCel Center is better, there is more parking space for horse trucks for example.
