The next big London AI date is AI & Big Data Expo Global at Olympia on 3 and 4 February 2027, followed in June 2027 by London Tech Week (7 to 11 June) and The AI Summit London (9 and 10 June at Tobacco Dock). The city has the scale to support them: the government’s latest AI sector study, published on 29 October 2026, found that 51.4% of UK AI companies are registered in London (DSIT AI sector study 2025). This guide from The London Report lists the events with verifiable dates, shows the data behind London’s AI scene, and tells you what we could not confirm.
It replaces our 2024 version, which was written around events that have since changed. For wider tech events see Innovation in the City: London’s Best Technology Events and Meetups, and for jobs in the sector see Top 10 Technology Companies to Work for in London. Dates change, so confirm with the organiser before you book.

Why London hosts so many AI events
The Department for Science, Innovation and Technology (DSIT) study, published on 29 October 2026, identified 10,488 UK AI companies in 2025, up 79% on 2024. Some of that rise reflects better coverage, but the report says it is underpinned by real growth. AI-related employment reached an estimated 130,400 (up 51%) and AI-related revenue rose 41% to £33.6 billion (DSIT AI sector study 2025).
London is the hub. Of the UK AI companies identified, 51.4% have a London registered office, and London, the South East and the East of England together account for 72% (DSIT AI sector study 2025). Events follow the companies, which is why so many AI conferences choose London.

AI & Big Data Expo Global (February 2027)
The 2027 edition runs on 3 and 4 February at Olympia London. The organiser’s agenda lists tracks including AI Leadership, Enterprise AI, AI Builders, Data & Analytics, Future AI, AI Developer and Physical AI, plus one-to-one meetings and a Learning Hub, and it labels some tracks “free” and others “gold” (AI & Big Data Expo Global). Check the ticket types before you register.
London Tech Week (June 2027)
London Tech Week runs from 7 to 11 June 2027. The expo and content stages are at Olympia on 7 to 9 June, and a fringe programme runs across London on 7 to 11 June. The organiser reports more than 31,600 attendees in 2026, and its site lists AI in retail, AI in finance and AI in critical infrastructure among the events in the programme (London Tech Week). Our own page covers the background: see London Tech Week.
The AI Summit London (June 2027)
The AI Summit London returns on 9 and 10 June 2027 at Tobacco Dock, and registration of interest is open. The 2026 event, on 10 and 11 June, was the 10th edition. Its programme includes a start-up and investor village, an AI skills accelerator training day, National AI Awards and a hosted buyer event (The AI Summit London). The 2026 edition had 10 stages and 14 tracks, five of them new (organiser FAQs).
Chief AI Officer Summit UK (February 2027)
A Corinium listing gives 23 February 2027 for the Chief AI Officer Summit in London, but we could not find a confirmed venue, so treat this as provisional (Corinium).
Data Science Festival, RE•WORK and community meetups
The Data Science Festival’s 2026 edition was listed for Saturday 16 May at CodeNode in the City, as a one-day event with tickets by random ballot (Meetup listing). We found no 2027 date. RE•WORK’s AI in Finance Summit London was listed for 15 September 2026 (Expomap listing). For regular, hands-on sessions, AI Tinkerers London runs builder meetups; its site notes that most chapters meet monthly, though frequency varies by city (AI Tinkerers London).
What London’s AI scene is working on
The DSIT study gives a data-led view of where London’s AI firms focus. Among dedicated AI firms across the UK, healthcare and wellness (17%), professional services (17%) and financial services (13%) were the leading application sectors. Financial services stands out in London, at 16% of London-registered dedicated firms against 9% across the other regions (DSIT AI sector study 2025).
| Measure | Figure | Source |
|---|---|---|
| UK AI companies identified, 2025 | 10,488 (up 79% on 2024) | DSIT AI sector study 2025 |
| AI-related employment, 2025 | About 130,400 (up 51%) | DSIT AI sector study 2025 |
| AI-related revenue, 2025 | £33.6 billion (up 41%) | DSIT AI sector study 2025 |
| Share of UK AI companies registered in London | 51.4% | DSIT AI sector study 2025 |
| Financial services focus among dedicated firms | 16% in London vs 9% in other regions | DSIT AI sector study 2025 |
| London-registered firms working in agentic AI | 22%, against 12% to 18% elsewhere | DSIT AI sector study 2025 |
The study also shows that agentic AI is a London specialism: 22% of London-registered firms work in it, against 12% to 18% elsewhere, while London recorded the lowest shares in AI implementation (9%) and perceptual systems (15%) (DSIT AI sector study 2025). Events with agentic AI and finance tracks are therefore a natural fit for London audiences. For the wider business picture, see our guide to the top industries in London, where information and communication had the UK’s highest high-growth rate in 2024.
What happened to CogX and the other events we used to list
Our 2024 version named AI Summit London, RE•WORK’s AI in Finance Summit and CogX. The first two still run, as above. For CogX, Wikipedia describes an annual festival that usually takes place in London in September (Wikipedia: CogX Festival), but we could not confirm official London dates for 2026 or 2027, so we have not listed it. If CogX confirms London dates we will add it.
How to choose an AI event
- Want a broad view of commercial AI? The AI Summit London or London Tech Week.
- Want enterprise and data tools? AI & Big Data Expo Global in February.
- Want to learn by building? A hands-on meetup such as AI Tinkerers London, or the Data Science Festival if you win a ballot place.
- Work in finance? The RE•WORK AI in Finance Summit, and the finance streams at London Tech Week.
- On a budget? Look for free tracks and free registration, such as those marked free on the AI & Big Data Expo agenda, and check each ticket type.
Making the most of an AI event
- Plan your agenda. Big events run many parallel tracks, so pick sessions in advance.
- Book meetings early. Some events offer one-to-one meeting tools.
- Follow up. Message the people you meet within a few days.
- Look beyond the headline events. See Innovation in the City: London’s Best Technology Events and Meetups for more London tech meetups.
Conclusion
London’s AI events are growing with the sector, and the government’s own data shows how concentrated that sector is in the capital. The 2027 diary has AI & Big Data Expo Global in February and London Tech Week and The AI Summit in June, and we will update this page as other organisers confirm dates.
