Big Data & AI World London 2027
by CloserStill Media Ltd.
The UK's largest free-to-attend data and AI show, inside TECH SHOW London at ExCeL
About This Event
Big Data & AI World London 2027 runs 10-11 March 2027 at ExCeL London and is the data and AI pillar of TECH SHOW London, CloserStill Media's co-located technology exhibition. It is aimed squarely at buyers: Chief Data Officers, AI strategists and senior technology decision-makers across healthcare, media, financial services and the public sector, with free entry reserved for buyers and consumers of technology solutions rather than vendors. The 2026 edition ran 15 conference theatres with more than 450 speakers, and the organisers arranged over 3,000 confirmed client meetings in advance of the show. CloserStill reports that 71 percent of visitors specify or influence purchasing decisions and 63 percent of attending companies are represented by senior leaders. The show is co-located with Cloud & AI Infrastructure, DevOps Live, Cloud & Cyber Security Expo and Data Centre World, so infrastructure, security and data leadership are covered on one floor and one badge.

Why Attend
For a UK data or AI leader this is the cheapest serious market scan of the year: two days, no ticket cost for qualified buyers, and the whole TECH SHOW London floor covering infrastructure, DevOps, security and data centre capacity alongside the AI content. The pre-arranged meeting programme means vendor conversations can be booked and filtered before travel rather than collected at random from a stand crawl, and the buyer-only entry policy keeps the corridors closer to peer conversations than to a sales floor.
