Open House Festival 2026: Showcase Your Business in Piccadilly & Jermyn Street
HOLBA invites members to take part in London’s largest celebration of the built environment.
We are pleased to announce that we will be participating in this year’s Open House Festival, taking place from 12–20 September 2026. For the first time, Piccadilly and Jermyn Street will be featured as an official neighbourhood within the festival programme.
Open House is a city-wide celebration of London’s built environment, offering free public access to buildings, spaces and experiences that are not usually open to visitors. The festival attracts over 250,000 attendees annually and plays a significant role in driving footfall, increasing visibility, and enhancing cultural engagement across participating areas.
For HOLBA members, this is a valuable opportunity to showcase your business, tell your story, and connect with new and diverse audiences, supported by coordinated promotion across both Open House and HOLBA channels.
