London Build Expo is a two-day construction and design trade show scheduled for 25–26 November 2026 at Excel London. The event has run since 2015, previously at Olympia, and is moving to Excel as part of a growth strategy; it will be co-located with elementalLONDON, bringing construction, building services and sustainability under one roof.36
The programme is aimed at professionals across the built environment, including contractors, architects, engineers, developers, housebuilders and public-sector bodies. Organiser Nineteen Group expects more than 25,000 attendees. The Excel listing describes 450-plus exhibitors and 900-plus speakers across 15 CPD-accredited stages; other event materials give different programme counts, so these figures may vary across listings.167
Topics include sustainability and net zero, digital construction and AI, fire safety, housing and infrastructure, modern construction methods, workforce skills, and architecture and design. Alongside talks and CPD sessions, the format includes an Architect’s Hub, Meet the Buyers, workshops and networking events. The venue listing also describes live music and other entertainment as part of the show.17
The move to Excel is the main development highlighted in coverage of the 2026 edition. Excel’s announcement frames the relocation as a response to the show’s growth and points to the venue’s space, facilities and transport connections.3 The event is scheduled to open 9:30 a.m.–5:30 p.m. on Wednesday and 9:30 a.m.–4:30 p.m. on Thursday.1
