London Build Expo 2026

London Build Expo 2026 moves to ExCeL London for what is billed as its most ambitious edition, expanding to 12 halls and welcoming over 650 exhibitors across construction, architecture, engineering, infrastructure and building products. Free to attend for trade visitors, the show is expected to draw over 25,000 visitors across the two days, making it one of the largest built environment trade events in the UK.

The programme extends well beyond the trade floor, with a substantial conference component featuring talks, keynotes and panel discussions across net-zero construction, housing delivery, digital construction technology and building safety. Dedicated strands address different professional audiences within the industry, from architects and structural engineers to quantity surveyors and project managers.

For architectural practices working on the delivery side of the sector, London Build provides useful access to the product and systems market in a single venue, alongside the opportunity to engage with the broader policy and commercial conversations shaping UK construction over the coming years.
