ElementalLondon 2026 will bring together the professionals, technologies and expertise shaping the future of building efficiency at Excel London on 25–26 November.
The UK's dedicated event for professionals working to improve the efficiency of commercial, industrial and large-scale residential buildings will bring together 25,000+ built environment and construction professionals, alongside expert speakers, leading manufacturers, solution providers and industry organisations.
The 2026 programme includes experts from across engineering, construction, property, sustainability, building services and government, with content focused on the practical challenges involved in improving building efficiency.
Across the dedicated ElementalLondon stages, sessions will explore decarbonisation, energy efficiency, HVAC, retrofit, building performance, net zero, overheating, heat networks and the future of sustainable buildings.
The programme includes five dedicated stages: the Climate Solutions Theatre, the NHIC Knowledge Hub, UK Housing Stage and CIBSE Build2Perform's Influence stage, alongside the co-located Sustainability Arena and further London Build stages.
Highlights include sessions exploring deep retrofit at scale, the future of commercial building standards, decarbonising London, tackling overheating and delivering healthier buildings, alongside practical discussions around the technologies and strategies needed to improve building performance.
The exhibition will bring together manufacturers, technology providers and specialist solution providers across heating, cooling, ventilation, renewable energy, energy management, building controls and water efficiency.
Confirmed exhibitors include major industry names such as Baxi, Danfoss, Daikin, Clivet, Mitsubishi Electric, Beijer Ref, Mitsubishi Heavy Industries and Excool Special Products, alongside a growing range of specialist suppliers and emerging innovators.
Beyond the stages and exhibition floor, ElementalLondon will provide dedicated networking opportunities to connect with the professionals responsible for specifying, designing, delivering and operating more efficient buildings.
Co-located with London Build, visitors will also have access to a wider programme spanning construction, architecture, digitalisation, housing, skills, building safety and innovation, bringing the built environment community together under one roof. London Build 2026 will have 450+ exhibitors, 600+ speakers, and a packed programme of CPD-accredited content.
Together, the two events provide a complementary view of the built environment, connecting the people delivering projects with the technologies and expertise needed to make buildings more efficient, sustainable and future-ready.
