London Build Expo 2026 at ExCeL London: two days of construction

London Build Expo is the UK's leading and largest construction show, bringing the entire built environment sector together under one roof at its new home, ExCeL London. The 2026 edition opens a new chapter: a new venue, a co-location with elementalLONDON, four new conference stages, and three new feature areas. Over two days, more than 25,000 registered attendees and 450+ exhibitors meet to do business, share knowledge, and shape the future of construction. The programme features 600+ speakers across 15 stages and 300+ hours of CPD-accredited training, covering AI and digital construction, sustainability, fire safety, health and safety, modern methods of construction, UK housing, and architecture. Beyond the conference, visitors can access the Architect's Hub with project displays and 3D models, Meet the Buyer sessions with top procurement teams, the Government Hub, and the UK's largest networking events for Women in Construction and Diversity in Construction. With a festival atmosphere of live entertainment, networking parties, and industry awards, London Build blends real business opportunity with a vibrant show floor. Whether you are a contractor, architect, engineer, developer, or supplier, the expo is an efficient way to generate leads, discover the latest products and technologies, and connect with decision-makers across UK construction.
